Christopher On Mon, Sep 30, 2024, 19:52 Wayne Irwin via RE-wrenches <re-wrenches@lists.re-wrenches.org<mailto: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. The battery will attempt multiple times, but if there is a load, (such as a well pump) the draw from the load will essentially prohibit the batteries from energizing the micros long enough to engage and produce. The only solution is to have a load controller or turn off all loads once the power goes out. Otherwise, during these "attempts to turn on" power in the house will momentarily turn on and back off and potentially drain the batteries down to lower than the point of which they can even attempt to restart. I spoke at length with Enphase upper engineering (not tech support) about this today. They now know that most of the tech support staff does not know this important information. Once the batteries are dead, they are very difficult if not impossible to jump start with a generator. At the recommendation of tech support we tried multiple times with the "approved" inverter generator which ultimatly just wasted our time. Even though the controller/switch will accept the gen power and pass the energy to the loads, it will not energize the combiner or batteries. If your goal is to have an autonomous system with Enphase, it's only going to happen with the IQ8's (at this point). This is a significant issue with retrofitting older systems. By the way: - We've received numerous desperate calls from (orphaned) Powerwall owners whose systems also won't turn back on. - ALL of our Outback systems were issue free. I hope this helps some of you. Good Luck out there!
