My understanding is that you can indeed include a generator.

In response to: What I Saw at Enphase - Mind Blown!

Comment from: Jim Jenal - Founder & CEO

In case it wasn’t clear, I am not associated with Enphase, other than being an enthusiastic installer of their products. That said, I believe the 10 kWh Encharge system contains 12 IQ8’s, and presumably 4 in the smaller unit.

I would not expect to see Enlighten try to model savings as that is a complex undertaking since utility rate structures are so complicated and diverse. However, there are companies that are good at doing that, for example we use EnergyToolbase to model potential system performance and apply it against historical interval data and the chosen utility rate schedule.

Thanks for taking the time to comment.

Oops - I missed reading on slide 39 that each 3.3kWh storage unit has a 1.28kW output (assume that is 3 * IQ8) - guys that is very, very nice!

Very innovative technology and great analysts presentation pack. I note two areas where I would love to know more. The first is basically how many IQ8 can you put into each 3.3 or 10 kWh storage unit? In Australia there is a huge pricing gap between peak time 2pm - 8pm grid electricity pricing and shoulder 7am - 2pm and 8pm - 10pm and off peak loads (10pm - 7am). The time hours before sunset to 8pm often generate 60 percent of our usage costs. In my typical scenario 4-6 kWh are needed over 2-3 hours. So an output of 2-4 kW for an hour or two would best economically cover my grid usage. This means a peak load storage unit is far more economically attractive than a base load storage unit. Something that can every day if need discharge fast! Your original 1.2 kWh unit took 4 hours to discharge - as only the one inverter per storage unit was released. Will your new units allow multiple 425W IQ8s to be installed per 3.3 kWh of storage? a 1, 2, 3 or 4 IQ8 per 3.3 kWh of storage would be a real game changer if it could be priced to give an ROI within 10 years - it could scale from base load to peak load depending on a customers needs. Secondly - will Enlighten or Enlighten Manager be enhanced to show financial performance of a PV system or benchmark my performance versus friends / a local community? Enlighten is great - a real differentiator for you. It could be superb if it was extended a bit more. I transfer a lot of daily / hourly data from Enlighten to Excel - simple because Enlighten doesn’t allow me to enter my 7 day a week 24 hour day cost of electricity in / value earned from electricity exported into a table - which could then be cross multiplied against usage to give me economic value derived. If I had that - I would love your reporting to death! I have 5 arrays in 3 compass bearing - I would love to see seasonal array performance at a glance (instead of half an hour of seasonal energy reporting analysis of each solar cell gymnastics I perform on Enlighten Manager to realise my North East and North West facing cells make 410 kWh per year and my SE cells average 310 kWh per year (as they only make half 60% of the power of the Northly facing cells in Winter). I have advocated for many of my friends to use Enphase - it would be great if we could readily compare our systems performance against each other. To me adding $ saved to Enlighten reporting versus only kWh produced or consumed would be a simple, yet killer feature to consider. Allowing each user to enter their specific 7 day 24 hour cost of a kWh drawn or provided would be wonderful to allow direct cost reporting from Enlighten would be wonderful. The social side of being able to blind or selectively benchmark is huge - look at what 3dMark / futuremark did when they not only created PC 3d graphics performance testing test but brilliantly added a world wide benchmark and ranking system - they revolutionised the game! Lastly - more specifics about what has to be done to integrate your new technologies to a M250 / S270 / IQ7 house would be appreciated. If I wish for power production with grid out - do I need your control (islanding circuitry) plus swap over all 36 micro inverters I own - or only one array of them - or can a hybrid mix exist but it will give different production performance? ALl up - many thanks - great work Enphase!

Thanks for the kind words (and for taking the time to comment).

I don’t have any insight into what SolarEdge has in store, but they don’t have anything like this in the market. SPI is next month, so it will be interesting to see how they respond.

The software is the entire key to how this works (assuming you have hardware that is capable of running it). The ability to coordinate without communication (let alone no master-slave relationship) is nothing short of astonishing. In fact, I’m reminded of Arthur C. Clarke’s line: “Any sufficiently advanced technology is indistinguishable from magic.” This was close to that!

Thanks for the excellent write up of the demo that very clearly explains how the IQ8 works under real life conditions. It does sound pretty extraordinary. Will other inverter makers like SolarEdge have anything like this to compete with in the near future or does Enphase truly have a deep moat that will take others years to catch up to? Wanted your impression of the battery solution they announced yesterday. Also, can you comment on their software and how important that is to the total Ensemble Platform? Appreciate your efforts to educate the market.

Awareness is critical for Enphase’s new revolutionary technology. There are literally millions of “anti-islanding” customers out there who will want this capability — in Hurricane Alley, Typhoon Alley, and basically anywhere where the grid goes down, sometimes for weeks after a hurricane or other natural disaster. Enphase’s IQ8 is the answer. All other microgrids are “dumb” as Raghu would say — Enphase is the first company to truly have a “smart” microgrid solution. Go Enphase!

Fascinating indeed. I am a homeowner in Florida and am considering the purchase of solar. FL is less solar-friendly than CA but it seems like a no-brainer to me, particularly with the fed credit. Enphase seems to be heading in the right direction with new partnerships and game-changing tech. Their financial picture concerns me and the Prescience Point report(s) make me even more gun shy towards them. You noted that 6+ and 7+ products will be compatible with Ensemble. Does that mean the 6+ and 7+ micros would provide the same mind-blowing functionality you saw with the 8s? I know it is early in the game but do you have a sense if there would be added costs involved with having the 6+ and 7+ products work with Ensemble? How about the Encharge storage offering they mentioned at yesterday’s Analyst day? In short, the case studies described exactly what I’m seeking so I’m trying to better understand if I should just wait for the 8s or I could go ahead and move forward with PVs, 6+/7+, and then add Ensemble software and Encharge storage when it arrives next year. Thanks for your great coverage on solar….

I am sorry to hear of your situation. You might contact the lease company and see what, if anything, they will do for you. Yet another reason why we hate leases! Jim

Our first bill was a shocker too. Our sales rep told us we would be paying our taxes, etc to the tune of around $19 per month for the Utility Company. Actually, they add up to around $40. Now we got our bill saying it is $120. That combined with the lease payment of $150 per month, we are paying about $90 a month more then we were paying for our level pay for electricity. We’ve read that we should use our utilities during the day when we are on sun energy. We’re so disappointed.

Hi there I recently had 20 solar panels installed,I have just recieved my first electricity bill, which are normally between 750/800 dollars After solar was installed I looked at the amounts on the box regularly and to often showed 3459 and figures higher or slightly lower I used my washing machine dishwasher and pool pump during the day ,there are just 2 of us Just recieved my latest bill and was horrified t see that it was 851.80 dollars The house on the bottom block has only 5 panels and they have 5 children much heavier consumption than us there bills are around 150 i am so upset with this bill can it possibly be correct feel like i have been stitched up completely

@Sunnyday –

Back in the day, we built an entire series of spreadsheets for each utility in our service area. Those spreadsheets encoded the details of all of the specific rate schedules that we had encountered. When we came across a new one, we built a new spreadsheet.

We would then take the monthly usage for the potential client from the past year and plug it into our spreadsheet. Usually our calculation matched the utility within pennies. We could then apply the monthly anticipated production of the proposed PV array to the past usage, and see what the new bill would be.

We operated that way for many years, confident that it was a reasonable, and reasonably accurate way to model savings - particularly compared to people who just said, “Oh, you will save $0.25/kWh produced!”

Alas, things are way more complicated today, particularly in SCE territory where all new solar clients are switched to time-of-use rates, which means that the quantity of energy produced has to be applied to when that energy is produced. Nowadays we rely on getting hourly interval data (via UtilityAPI) and we use Energy Toolbase to incorporate that hourly usage data against hourly production data, and then model that against the appropriate rate structure. Again, we believe that is the most honest approach we can offer.

You might be interested in the three-part series that we are working on now that talks about these issues. You can read it here.

Thanks for the comment!

Jim

Spot on analysis. I hope LG does get an exemption since clearly they have a high-end premium product that does not compete with the cheap panel models which caused the complaint to be made. However, LG, like Jinko Solar, does have the option of setting up manufacturing here in the USA and avoid any tariffs whatsoever on the first 2.5GW of solar panels manufactured. According to Jinko, setting up a plant here in the USA takes about 9-months timeframe. Living here in Florida, the news of a Jinko Solar $410M plant investment in Jacksonville, Florida, is big news. I hope things turn out OK for the LG NeON-2 ACM’s, as well as other LG solar products. TIme will tell the tale.

Ironically, the utility companies’ policy (which yes, is what the CA laws allow, but I am certain is what their political action committees created) - those policies de-incentivize any conservation. Even with solar, which is only installed and paid for by a small percentage of the population, conservation is (or would be) important if we really care about reducing carbon emissions, sustainability, etc. The current policy encourages me to use every bit of the solar I have produced, because those excess kWh are the cheapest ones I will ever get. If they cost the same as 1kWh over production, then it really would be 1kWh for 1kWh and make sense to just conserve (as well as be a greater incentive for people on the fence to install, since they could recoup their investment sooner.) I need to buy another electric car and start charging it!
