I just returned from two days of hands-on training with the new Ensemble Storage System from Enphase Energy at their HQ in Fremont, California.  Here’s my take… Ok, to say that I have been somewhat obsessed over the Enphase IQ8 and its…

We recently received PTO for a new project in Altadena, and part of what made this interesting was that we decided to modify the project mid-stream so that we would be positioned to add an Enphase Ensemble Storage System down the road.  We wanted to…

Readers of this blog are well aware of the fight being waged before the California Public Utilities Commission (CPUC) as we first wrote about this back in February!  Now we are entering the final stretch in this fight, and quite frankly, we are losing.…

tl;dr - Come Rally with us on June 2, at 10:30 a.m. in Grand Park, DTLA! As readers of this blog know only too well, the California Public Utilities Commission (CPUC) had proposed - at the urging of the investor-owned utilities (IOUs), that is SCE,…

Good article. TOU rates, tiered rates, demand-charge fees, etc. They're all concocted to keep the revenue stream of the energy monopolies going. Warren Buffet and his cronies have enough. It's time to end the monopoly. Residential storage is in its…

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…

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…

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!

I would not wait as we don't know how soon the IQ8's will be available (we have a shortage of IQ7's right now). I am assured that they are compatible, but that you will need a certain "critical mass" of IQ8 (30-50%) to allow the microgrid to operate. My…

Hi Jim, This read just erased about half the anguish of missing last week's conference. A few questions: 1. ATS/Meter intercept wiring challenge for combo meters: As desirable as a combo meter solution might seem, leaving pool pump/HVAC type loads on…

Thanks for keeping us updated Jim! I love the potential of IQ8 especially when coupled with storage. My interest is in both on and off grid versions. So many use cases...RV trailers, shed power for charging up the lawn mower, water pumping, greenhouse…

Srikanth -- I'm glad this was helpful. Here's the explanation, it is called "anti-islanding" and it is an important safety feature. Think of it this way - let's imagine that the grid is down because a tree fell over a power line and snapped it. The…

Bill - would need to know the specifics as to each device. The question is whether the peak output from the combination of the array (limited to 5.025 kW max - but normally some significant deviation down from that during the day), plus the peak output…
