Ladies and gentlemen, thank you for standing by and welcome to the Enphase Energy Fourth Quarter 2019 Financial Results Conference Call. [Operator Instructions] I would now like to hand the conference over to your speaker today, Adam Hinckley. Please go ahead, sir.

Good afternoon and thank you for joining us on today’s conference call to discuss Enphase Energy’s fourth quarter 2019 results. I am the Head of Investor Relations for Enphase Energy and I am pleased to be hosting my first earnings call for the company. On today’s call are Badri Kothandaraman, Enphase’s President and Chief Executive Officer; Eric Branderiz, Chief Financial Officer; and Raghu Belur, Chief Products Officer. After the market closed today, Enphase issued a press release announcing the results for its fourth quarter ended December 31, 2019. During this conference call, Enphase management will make forward-looking statements including, but not limited to statements related to Enphase Energy’s expected financial performance, technology, new products, operations and sales and marketing. These forward-looking statements involve significant risks and uncertainties and Enphase Energy’s actual results and the timing of events could differ materially from these expectations. For a more complete discussion of the risks and uncertainties, please see the company’s annual report on Form 10-K for the year ended December 31, 2018 which is on file with the SEC and the annual report on Form 10-K for the year ended December 31, 2019 which will be filed with the SEC in the first quarter of 2020. Enphase Energy cautions you not to place any undue reliance on forward-looking statements and undertakes no duty or obligation to update any forward-looking statements as a result of new information, future events or changes in its expectations. Also please note that financial measures used on this call are expressed on a non-GAAP basis unless otherwise noted and have been adjusted to exclude certain charges. The company has provided a reconciliation of these non-GAAP financial measures to GAAP financial measures in its earnings release posted today, which can also be found in the Investor Relations section of its website. Now, I would like to introduce Badri Kothandaraman, President and Chief Executive Officer of Enphase Energy. Badri?

Good afternoon and thanks for joining us today to discuss our fourth quarter 2019 financial results. We had a good quarter. We reported revenue of $210 million and shipped approximately 2.1 million microinverters. Demand was strong for our microinverter products in Q4. We are pleased with the preorders for our Encharge battery utilizing our Ensemble energy management technology and have started training installers to support the upcoming product launch. We exited the fourth quarter at approximately 37, 12, 25. This means 37% gross margin, 12% operating expenses and 25% operating income, all as a percentage of revenue on a non-GAAP basis. As a reminder, we introduced our new baseline financial model of 35, 15, 20 at our Analyst Day in December. The baseline model represents the minimum financial performance we expect to achieve over the next 18 to 24 months while demonstrating meaningful top line growth. Eric will go into greater detail about our finances later in the call. Let’s now talk about ease of doing business, how customers perceive us. Our Q4 net promoter score was 56% in North America compared to 54% in Q3. Our average call rate time is slightly over a minute and we are working on several self-service initiatives to reduce call volumes. We recently opened our online Enphase 2 with the objective of providing even better customer experience. Our target is to exit 2020 with an NPS score greater than 65, a number that’s considered very good in our industry. Let’s talk about the impact of the coronavirus. Our thoughts and prayers are with the people of China as they fight the virus. Our priority is to ensure the well-being of our teams as well as our partners in China. Our contract manufacturing facility – partner facility in China is steadily ramping back up…

Thanks, Badri. I will provide more details related to our fourth quarter of 2019 financial results as well as our business outlook for the first quarter of 2020. We have provided reconciliations of non-GAAP to GAAP financial measures in our earnings release posted today which can also be found in the Investor Relations section of our website. Total revenue for the fourth quarter of 2019 was $210 million, including approximately $36.4 million of safe harbor revenue. Total revenue for the fourth quarter of 2019 increased 17% sequentially and increased 128% year-over-year. We shipped approximately 677 megawatts DC in the fourth quarter of 2019, an increase in megawatts DC of 16% sequentially. The megawatts shipped represented approximately 2.1 million microinverters. Non-GAAP gross margin for the fourth quarter of 2019 was 37.3% compared to 36.2% for the third quarter of 2019. Expedite fees are now normalized within our expected range and therefore did not have an abnormal impact in gross margin. Our component supply is stable and as a result we will no longer quantify this expense if it is within the normal course of business. Non-GAAP operating expenses were $26.1 million for the fourth quarter of 2019 compared to $25 million for the third quarter of 2019. GAAP operating expenses were $33.4 million for the fourth quarter of 2019 compared to $31 million for the third quarter of 2019 and GAAP operating expenses for the fourth quarter of 2019 included $5.6 million of the stock-based compensation expenses, $545,000 of amortization expenses for acquiring intangible assts and $1.1 million of restructuring expenses. Our restructuring program was completed at the end of 2019 and at this time, we do not anticipate any further or future expenses related to restructuring. On a non-GAAP basis, income from operations was $52.3 million for the fourth quarter…

[Operator Instructions] Our first question comes from Brian Lee with Goldman Sachs. You may proceed with your question.

Hey, guys. Thanks for the questions and congrats on the strong quarter. I guess maybe first question on the Q1 guidance, the safe harbor revenue, appreciate all the granularity of providing around the dollar figures, can you also give us a sense of what the customer mix looks like, I know in Q4, you had specific called out the one customer, SunRun, is it the same customer in Q1, is it a totally different customer in Q1 and if it’s a different customer, are there multiple customers? That will be the first question I have.

It is a different customer. In fact, there are multiple customers, yes, for the safe harbor, long-term $44.5 million.

Okay. And Badri, it’s safe to assume that our Tier 1 installers, as you mentioned during your prepared remarks, there is only a handful of data due to the safe harbor?

Yes.

Okay, fair enough. That’s helpful. And then I guess if I – I don’t want you to – I don’t want to corner you into give any more guidance than you are willing to provide, but you did try to provide us a little bit of sense around Q2. So when I look back at the Q2 revenue trends historically, there has been about an average of 30% give or take sequential revenue growth and also a similar range for volumes if I look back to the model, dating all the way back to the 2010s. I know a lot has changed over the period, but is that the type of seasonality we should expect in Q2 this year as well based on your incumbents around healthy bookings and seasonality on core revenues, again, assuming no safe harbor and then no incremental coronavirus impact being the base cases, just wondering if that’s sort of the read we should be taking away from your comments? Thanks.

Yes. I mean, that’s a good question. As you correctly said, Q2 is quite seasonally strong whether the number is 20% or 30%, it’s hard for us to say at this point in time, but in general, we expect to outperform the industry seasonality.

Alright. And then maybe last one if I could squeeze it in, just around the Encharge, it’s encouraging to hear you guys are on schedule for the shipments in Q1, one of your peers who also has a new product in the market. Just last week, Generac announced that they are raising their target for shipments by 50% versus there original view, any thoughts around kind of the market makeup as you are seeing early traction of preorders and also to March and just in the context of your 5% attach rate, is there potentially some upside as you move through the year given how the market is developing? Thanks guys.

Yes, I mean, look we are extremely excited by our product. In fact, Encharge is running well at all three of our houses, my house, Eric’s house, Raghu’s house, we are all running. In fact, I went off-grid this morning for about 8 hours. So we are really happy with the performance of Enchage so far. And of course it’s time for us to bring to the market. Ours – if you really step back and think about it, why installers like that solution a lot and this is what the installers told us is really it’s the all in one solar and storage system, seamless experience for the homeowner, one number to call, very high quality, very high customer experience, safe AC architecture, all controlled by Ensemble energy management technology. That’s our value proposition. And we are sticking to our value proposition, there is obviously a lot of competition, lot of noise in the market, but I think our value proposition is quite difficult to compete against. So, we will – many people are coming, we will see them in the marketplace, that’s all I can say right now.

Okay. Thanks guys.

Thank you. Our next question comes from Mark Strouse at JPMorgan. You may proceed with your question.

Yes, thank you very much for taking our questions. Badri, I just wanted to go back to the comment that you made about the impact from coronavirus and what’s included and what’s not? I believe you said it’s possible there could be some expedited shipping fees, is that included or excluded from the 36% to 39% guidance that you have given?

We have already included that in the guidance we gave you.

Okay, thank you. And then you have been talking about expedited shipping fees for several quarters now, excluding the wildcard from coronavirus, can you just give an update there? Are you tracking expectations having your capacity be above expected demand?

Yes, I mean, look we used to have expedite charges of more than 200 basis points before. That situation has changed. We are now normalized with respect to expedite it’s really in the noise. Of course, due to coronavirus, we have planned little bit more than usual, but that’s already factored in the guidance and going forward if the situation normalizes with respect to coronavirus we will – expedite is going to become nice. It’s not going to be significant for us.

Okay, thank you. And then just one quick follow-up for Eric starting next quarter, with the Encharge starting to ship in March, how should we think about any metrics that you are going to give around those shipments – or those revenue beginning in 1Q?

Yes. So we are considering the possibility that starting in Q3 we may start providing breakouts on revenue. We haven’t made the final decision yet. There are external reporting considerations, but we understand that when this becomes meaningful part of our ramp, it will create a little bit of a problem for you folks to be able to model and we are very sensitive to that and we will address it when we have more visibility into how that will workout for external reporting.

Okay, very helpful. Thank you.

Thank you.

Thank you. Our next question comes from ` from Credit Suisse. You may proceed with your question.

Hi, good evening. Thanks for taking the questions and congratulations on the strong quarter. Maybe just on the other product launches just mentioned on the Analyst Day the IQ 8 and IQ 8D could you probably just talk about how you are thinking about the rollout of those products, specifically given the supply chain disturbances in China if any?

Yes, I mean for those, basically we are thinking about the second half of the year, it’s the rough order would be the IQ 8 microinverters on the roof would be the first followed by the commercial microinverters followed by the Ensemble in a box.

Got it, thanks. And just probably going back to the Encharge, could you just talk about like how much do you – should we expect from Encharge in Q1 specifically or is mostly a Q2 number?

We’ll have small shipments of Encharge in Q2 – I mean in Q1, but nothing significant in terms of revenue. Q2 will have one full quarter of Encharge and we expect that to be nice.

Got it. And just lastly on taxes, I just wanted to make sure we understood that correctly, so from a tax perspective it’s minimal cash taxes and like a standard GAAP tax rate in line with the U.S. corporate tax rate, is that a fair statement?

Yes, you got it. Think about $59 million of cash savings for the monetization of the NOL and tax credits, right. That’s for my cash. And for P&L, we give you all the data to be able to morrow on a non-GAAP basis. When those are exhausted, we flip GAAP and non-GAAP will be the same.

Got it, right. Thanks for taking your questions.

Thank you.

Thank you. Our next question comes from Colin Rusch with Oppenheimer. You may proceed with your question.

Thanks so much. Can you guys talk a little bit about the growth in Europe, how effective you have been in being able to build out the sales team and how much of the 1Q guide is especially come out of non-North American sales?

Yes, I mean, we don’t really breakout the exact numbers for Europe, but I did give you some color this time, on the total revenue for 2019 was $68 million. Our plan is to double it in 2020 to go to $136 million. And like what I told you, we have not been happy with our progress in Europe, but that has changed. Now, we are actually doing very well. We have hired already bunch of sales guys in place. We have internal transfers from the U.S. already in place, they have already started. And so in terms of headcount, approximately 5 sales people was the number we had in 2019 and that number will triple as we get towards March and April. So we are tripling our sales headcount in Europe. We are focusing on the right regions. Our sales guy in Germany already started. He is driving the collaboration with Kraton. We have already hired the guys for Spain. And we are doubling down on Netherlands, our most important area. We are also going to double down on France, where we have a very high market share already. Yes, I mean it’s a good story right now. We are very confident that we are going to make progress. We are very confident of start seeing an uptick in revenue as early as Q1.

Great. And then as you think about the battery supply chain and your cost structure there, how should we think about the cadence of cost reduction, I am assuming that you are going to go through a series of costs as you get to higher volumes, but just trying to get a sense of what the order of magnitude is on that and how quickly we might get to some of those cost breaks?

Yes, like what I told you guys in the Analyst Day, cost reduction is embedded in our DNA, that’s what I call as operational excellence. We look at all kinds of costs. If I look at microinverter costs, I look at the transformer costs, defect costs, the connector costs, for example, the connector yes I can talk about that for hours. So we have a DC connector in our microinverter. Today, we have an adapter cable that converts the connection from the panel into a proprietary connector on the microinverter. We are going to eliminate that adapter cable by building what is called as an MC4 light connector on the microinverter. That alone will save us roughly $2 to $3, but that’s going to take some time. It’s going to take some time. It’s going to be done over multiple quarters. That is just an example of one. We are focusing on transformers. We are focusing on the – always on sourcing the right AC effects. We are always working on combinations where we can integrate more components into out ASIC. So that’s on the microinverter. On the accessories, gateway is an entire exercise. Our Envoy is – we are spending a lot about trying to take cost out of the Envoy, the same effort on the cable and we will apply the same diligence to Encharge going forward. So, that’s why you see our gross margins kinds of sequentially going up. If you see the Q4 number or Q3 number was 36%, Q4 ‘19 we did around 37%, we are guiding 36% to 39% for Q1. So, we are getting more and more executing well on the cost deduction.

I will take the rest of it offline. Thanks guys.

Yes, thank you.

Thank you.

Thank you. Our next question comes from Jeff Osborne with Cowen & Company. You may proceed with our question.

Hey, good afternoon. Just a couple of questions of my end, I was wondering if – I know I’ve asked you this in the past, Badri, but if you just confirm that with Encharge, the launch of that margin profile would be consistent with the corporate average or how do we – I think Colin was trying to ask about that as well, is the initial phases of the launch pressuring margins in Q2 and Q3 and then as you say cost out will come back to the targeted range?

No, it’s not going to compress our margins it’s going to be right in line with our model.

Great. That’s great to hear. And then can you just talk about IQ 8 introduction for solar-only deployments, is that still targeted for Q2, Q3? So right now, it’s in the Encharge solution, but how do we think about it, somebody doesn’t want storage, when will that be available?

So, as I said, it’s in the second half of 2020 and yes, it’s almost ready. And basically you rightly pointed out it’s already available inside the Encharge, but of course we have to do a lot more work with lot of flavors on IQ 8, which is IQ 8, IQ 8+, the IQ 8X, the IQ 8A and then the real effort is to make sure that the gateway talks to the same language as IQ 8 and ensuring that we do all the due diligence on quality on the various flavors. So, we might do it, earlier things go better, but for now I am just – I am not giving a quarter, but I am saying generically second half of 2020.

Got it. And the last one I had either for yourself, Badri or Eric, just how do we think about the second half as your Mexico capacity ramps up to the million a quarter target and what the implications are for pricing as you sort of reverse the higher prices that you had experienced in 2019, because of the tariff fully recognized and it doesn’t impact the gross margins, but just it would be important for modeling as we think about ASPs per watt?

Like what I said, our – if you think about gross margin, gross margin is a combination of pricing and cost. We are continuously improving our cost in terms of pricing. We know right now the pricing environment is very stable, but of course, we always model 1% to 2% price reductions every quarter, that’s what we do.

Got it. Thank you.

Thank you.

Thank you.

Thank you. Our next question comes from Philip Shen with ROTH Capital Partners. You may proceed with your question.

Hey, guys. Thanks for the questions. First one is on the coronavirus situation, I was just wondering if you could give us a little bit more color on what’s happening on the ground there in their facility? So specifically, what kind of capacity utilization have you been running through this tough time and then how do you expect that to trend in the coming weeks? And then what kind of potential impact do you think you could see in Q2? And then finally, you source any critical components from Hubei Province specially?

Thanks. So just to give you a quick thing, we make all our microinverters at Flex for young [ph], that’s about 12 hours drive from Wuhan. We have done our homework in terms of the raw materials, the supplier of the raw materials etcetera. Most of our raw material suppliers are in Suzhou and Hangzhou which are also a little bit away from Wuhan. From our diligence checks, our raw materials aren’t, they aren’t affected. And so if I were to think about the entire situation in terms of priority, I would think the following: number one is labor, is labor back in full force or not, the labor in our Flex factory is roughly about, because of the reduced labor our throughput is roughly 50% of the full capacity which is still pretty good for us and then the second priority or the second constraint that we think about is logistics we hear that the outbound logistics from China is getting difficult and so we are always watching our we are paying attention to that the third is a raw materials that you pointed out which we have done the homework we think we are good there. The fourth is obviously we are doing this conference call so late 7 weeks into the quarter if the revenue guidance for the quarter is X we have already shipped 7 over 13X right now that is what I mean by I am at 100% lane we have already shipped that revenue 7 over 13 multiplied by X is what we have shipped the last one is what god he is doing over a 50,000 units a week and of course what depends on the raw material from China and so there is always risk there but we feel pretty good about that guidance right now we have factored all of this situation in both revenue as well as gross margin guidance and considering that we one of the data point is we are fully booked to the guidance that we gave you we are fully booked we are 100% linear we have done the homework in terms of raw materials we are paying extraordinary attention to logistics and so at this time we feel pretty good that if that situation materially changes because there is something that we don’t know we will come back to you but that’s what we know now.

Okay. Thanks Badri. But as it relates to Q2 I know you have not provided official guidance you talked to Brian about seasonality kind of being in lines is slightly better than historical or something like that what is the risk to Q2 obviously you have already shipped for Q1 so the question is what is your view on how lets say the current situation remains at this level 50% of full capacity how does that impact what you can deliver on Q2?

In the current situation I mean the situation remains the same we will be I don’t think will be in and I don’t think we will have a problem for Q2 if it remains the same the reason is of course we are making good progress in Mexico that is starting to take the burden more and more we are keeping a close eye on the raw material so all things being equal if it were exactly the same in a few days from now and Q2 beginning I am still pretty optimistic about Q2 but you don’t realize that things can change by the day so that’s all I can tell you right now.

Okay, great. That’s really helpful. Thanks. Shifting gears to pricing I know you talked about that briefly but historically you guys have talked about as you shipped away from China and from Mexico that you test long that pricing to customers earlier probably a few months ago you are talking about may be a price cut starting April 1st to pass it on to customers seems like our recent checks with customers that you are not necessarily getting you have not been actively talking about that what is your view on a potential for price reduction and at what point of time would you expect that to possibly happen?

Right. Yes, so we are clear when the supply chain right now is in turbulence due to the coronavirus. Other suppliers are thinking about raising the prices we are not we basically value our customers this time we think that they have already taken a lot of burden on the tariffs so we are not planning to raise prices and it is not prudent for us to also drop prices without understanding the situation on the supply chain due to the virus. So if things stabilize, we will do exactly what I said, which is basically depending upon the percentage of manufacturing in [indiscernible] versus China for North American shipments we will basically reduce prices to that level. And that will happen sometime in Q3 if the situation gets stable in terms of the coronavirus. If not, we got to wait and watch.

Thank you. Our next question comes from Brad Meikle with Williams Trading. You may proceed with your question.

Hi, guys. Thanks for the question. So your U.S. business grew 137% year-over-year in 2019, so can you give us some detail in terms of the level of inventories in the channel today versus a year ago? So we can understand how much market share has changed that is because other checks are indicating that SolarEdge inventories are higher in the channel than they were a year ago? I know you get POS data on your inventory in the channel, so can you add any color on that please? Thanks.

Yes. We think the reasonable level of inventory to have is usually 8 to 10 weeks and we tried to maintain our channel inventory between 8 to 10 weeks like what I pointed out the last earnings call. But what you said is right we have grown a lot in the last year. Mainly the growth is because of our IQ 7 product, fantastic product it’s due to quality, due to customer experience. We have made a lot of announcements with Tier 1s. We have made a lot of announcement with the long-tail installers. We recently signed up Petersen-Dean and SunRun as well. Things look good there. But as long as we don’t take our eye off the ball in terms of customer experience, I believe we will continue to take shift.

Can you quantify though what that market share is today in U.S. residential versus a year ago?

So, Brad, I mean, we don’t really track – we don’t really think market share. We control the inputs, but we don’t really track the output. So it would be – I don’t know the number and I am not going to that I am not standing by, okay?

Thanks. I mean, it’s obviously a big number given that the market is growing at 25% and you grew at 137% without much inventory growth, so what about storage, can you add anymore color on the beta installs, however many 500 to 800 that have been done, what your feedback has been from the customers, have you gotten follow-on orders? It sounds like April is when production volumes really start off. Can you give us a sense for, I know there is a day and a half training required for an installer? Can you give us some level of understanding what the ramp up might be? I know it’s a new business, but what is the theme like at this point?

Yes. Just to get our terminology straight, right now, we are doing what are called as alpha. Alphas are basically near and dear people is what we are doing and like what I said to Eric’s house, my house, or Raghu’s house are all running full Ensemble. And that’s what we have done. So we are giving feedback to the team. There aren’t any major issues. There are always minor in our teething issues that are there in this. And now coming to the second thing is the training, the training of installers. We have trained all our beta installers. So they are our – what we call as the ambassadors that we claimed in the first round. So we obtained about 70 installer personnel and 32 installation companies. These farm our beta network and that essentially in the first week of March they will start installing – pardon, the second week of March, they will start installing beta systems. Ad we are going to get further feedback from that. By that time our compliance will also be done. And so we will be in a very good position in order to ship the product. But in terms of the performance of the product, we are actually exercising it. Like in my house like yes, like what I said this morning I was off-grid for about 6 hours. And everything goes finally, didn’t even – someone has flipped my app to go from on-grid to off-grid, so we can enter it through the app and they were doing a test in my house and I didn’t even know that I was off-grid. That’s a big deal. If I can make that customer experience seamless, it’s all going to be that. We can make that customer experience seamless, I think so there is a lot of upside here.

Thank you. Our next question comes from Jeffrey Campbell from Tuohy Brothers. You may proceed with your question.

Good afternoon and congratulations on the strong quarter. Badri, at the Analyst Day, it was said that other than possibly the price that DC cannot compete with Enphase, and that's what I have me thinking about the IQ 8D and the and the small commercial solar I was thinking even with higher unit ASP IQ 8D reduction in components should see system costs come down relative to the IQ 7, so is it fair to think of it that way and could the IQ 8D be the first Enphase macro that will benefit from quality service and cost competitiveness?

Yes but it is not because of the reason you said our architecture is a scalable architecture fully resonant architecture so we are able to what we told you in the analyst day is that the power density for our product is 50% higher for IQ 8D than IQ 8 which means we are able to pack a lot more power not more power in the same form factor and of course that translates into cost and of course we are going to be competitive but we do not price on cost we price on value what is the differentiation with respect to our next best alternative we will have to look at what is in the competition and what value are we specifically providing is it higher quality is it better customer experience is it better installation less labor all of those factors need to be looked at and then we will price our products.

Okay well, that’s very helpful And then I also want to ask about the Kraton partnership that that you sent a press release on out recently it looks like it’s a large operation there is 8 factories but I have no sense of how large the client on retail market is or Kratons place in that market so some color there would be helpful and I also wondered if the installer relationships that Enphase will build through Kraton can go beyond claytie installation?

Yes the idea is very neat right. If you basically have in-roof solar, and you do it for new homes you would think that it can it basically can catch on like wildfire right but this is an entirely brand new market we have not seen it kick off I expect that it will be a slow and steady growth because we are introducing it in a matured country like Germany. Germany is very strict on quality is very strict on customer experience they would not ramp something as fast it is going to be in a measured way but the advantages are very, very clear it is an AC roof basically standardizes everything and it will reduce the cost of an installation it by definition the modules are built in the factory including the microinverters quality is going to be very high and it is all in all a good experience for the installer so the installers obviously they want it but at this point it is too early for us to talk about the wrap.

Thank you. Our next question comes from Eric Stine with Craig-Hallum. You may proceed with your question.

Hi everyone. Few quick questions here. The end maybe just on Tier 1 customers, I know a couple of years back you took the action to kind of step away there and late last year picked up sun run these new safe harbor customers that you referenced just curious what kind of contribution you expect from those customers as they come back in 2020 is it meaningful in 2020 and more of a 2021 or do you expect that it could impact 2020 nicely?

Yes, we did the safe harbor with SunRun in Q4 and we are doing safe harbor in Q1 with the couple of customers who are not new who are our existing customers the answer to your question is we expect them to use a lot of the safe harbor material but that does not mean that they would not place additional orders in the quarters of course the orders will be in the reduced magnitude but I think they will still be tightened that is what I think.

Okay, got it. And maybe last one for me just I know it is early here in the new year, but the new home mandate in California, whether you are starting to see an impact or how may be your view has changed or starting to become more clear and then just curious and do you have in mind kind of a share of that markets since you're partnered with SunPower and the Peterson and Dean relationship?

I mean it is one way here I have to rely on our partners like SunPower like Peterson and Dean like Lennar homes, these are our partners. They are our front-end to the homeowners to the home builders and so we expect it really well because of our partnership with SunPower here and partnership with Peterson Dean and like our imagine a house being fitted with like for example in the case of Peterson just imagine a house being fitted with an all in one solar and storage system with beautiful in charge in the Enphase solar system that is going to be an amazing customer experience for them.

Got it. So this is I mean still thinks I mean it has not changed either way you still think it is a big opportunity and may be still too early to tell the magnitude?

Absolutely. I mean it is a nice opportunity for us we are ideally placed because many of these will be small systems and if these small systems the whole point of micro inverters is I can build small systems very easily whole point of Encharge is I can do modularity flexibility very easily I can do 3.3 kilowatt or 6.6, 9.9 or 10 kilowatt hour and I can add chunks later depending upon the customer need for example Raghu has got a 10 kilowatt hour system he wants to add two more 3.3 I have a 16.8 kilo watt hour system Eric has got a 20 kilo watt hour system so each of us are different and the modularity really helps us to fine tune exactly what we want.

Got it. Thanks.

Thank you.

Thank you. [Operator Instructions] Our next question comes from Sameer Joshi with HC Wainwright. You may proceed with your question.

Yes good afternoon. Thanks for taking my questions. What are the products that are being pushed in Europe are they IQ 7 and 7+ based or are you pushing for IQ 8 as well there?

Most of Europe right now today is 72 cell modules I believe and so that’s basically IQ 7+ and IQ 7 are the predominant cells in Europe.

Okay. Coming to the safe harbor sales, are the gross margins similar the gross margin profile similar for a safe harbor versus non safe harbor sales?

Since we are actually shipping to Tier 1, the gross margin in terms are a little bit lower but as you can see we have made extraordinary improvements in gross margins so you can see despite our huge shipments of safe harbor in Q4 our gross margin increased from Q3 to Q4

Right. Same with the midpoint of your guidance for Q1 right we got our referencing point there either on the low end or high end of the range in all cases.

Yes, in all cases, it is pretty healthy.

Understood. Moving down the operating expenses, the G&A costs or other overall OpEx calls that have been guided for 1Q, are they representative of the rest of the year or does the first quarter have some extra stock-based comp?

Yes. So most of the infrastructure investments that we need to make for the headquarters, many of the IT improvements that we need to do actually will heat OpEx, so what I will say is that we provided the guidelines of 15% of revenue and our view is that the way you guys who know it is by taking that one as kind of base line and then it could be a little bit better than that but for the most part you should consider that to be best I mean investment lines through R&D increases a little bit of the sales in Europe and some of the IT infrastructure security things that we need to do for the company that in the old ways those used to be of a CapEx. Most of the subscription base or license-based IT investment that we need to make is on now P&L, here in the P&L. So that’s the way we are going to be subsidizing through the P&L in the form of investments and our infrastructure growth and supporting the growth.

Understood. And just maybe just one clarification on the ASP per unit per inverter, if I do a back of envelope calculation based on your revenues and total number of units sold, it seems that the ASP is actually reduced over the last several quarters. I know it is not a accurate way of looking at it, but is this trend expected to continue?

No, I mean it’s not an accurate way of looking at it. It basically depends the way you look at it, your calculations, take revenue, overall revenue divide it by the number of microinverters is not the real story, because for example, if we do ship our AC batteries which are our first generation batteries. Each of them has got an ASP of $1,000. So we are not breaking those, but your calculation includes those. If we ship a lot of cables for example, if we ship by disproportionate amount of cables, the overall revenue will actually come down. If you ship, I mean, the overall ASP will actually come down. So it’s a heavily dependent on mix. But what I can tell you is this we pay very close attention on what we call as customer variance that we reduced price at a customer – and specific customer and calculate that. And we roll that up. And those numbers are actually very, very less. So, there is really – pricing is very healthy, pricing is flat. And except for what I talked about in terms of the [indiscernible] transition, we don’t see many changes to pricing.

Until it’s good for them to model some price erosion, on their models, right, we always recommend…

We always model 1% to 2% for our modeling. So that is the right way to think about it.

And it will get a little more complicated with Ensemble coming onboard, right. So we will provide some help hopefully for you guys tomorrow when the meaningful revenue of Ensemble starts to become more clear right.

Thank you. Our next question comes from Pavel Molchanov with Raymond James. You may proceed with your question.

Thanks for taking my question. In its mid-term review, the International Trade Commission talked about potentially adjusting or even setting aside the Section 201 tariffs. As it relates to the AC module relationships you have, is there any read-through depending on what the decision will be?

No, I think there was a lot of discussion about it, but we have not heard anymore discussion on the tariffs going away and we also know that there is exclusions there. So I don’t believe that, that can play right now.

Most of our volume business with SunPower already is excluded so.

Understood. And you have already asked about one of the new entrants Generac, if I may, let me ask about another one, LG, can you confirm whether LG is currently a customer for your microinverter as a component to LG’s integrated module product?

No they are not a customer.

Okay, thank you very much.

Thank you. And that concludes our Q&A session. I would now like to turn the call back over to Badri Kothandaraman for any further remarks.

So, thank you for joining us today and for your continued support of Enphase. We look forward to speaking with you again during our Q1 2020 earnings call in April. Thank you.

Thank you. Ladies and gentlemen, this concludes today’s conference call. Thank you for participating. You may now disconnect.
