Thx Wayne.
Curious, I guess they are in a sense AC batteries, as there is no way to access them for DC jump charge? And I guess that is the same with Tesla? In that there is not way to access the battery, or they didn’t figure you’d actually have a true black start? thanks for the info. jay > On Sep 30, 2024, at 5:51 PM, Wayne Irwin via RE-wrenches > <re-wrenches@lists.re-wrenches.org> wrote: > > Hurricane Helene has taught us the hard way that Enphase batteries with > anything other than IQ8's won't restart. > The issue is that when the batteries try to restart (at the non-programmable > time of 9:AM) if there are any significant loads, the batteries will not stay > on long enough (300+ seconds) for any non-IQ8 micros to energize.
