Any ideas?
Today we had grid outage for about an hour, really the first time (when I could look into it) during a brilliantly sunny day since commissioning our 3rd generation system about 18 months ago. SC3G, IQ8+ producing about 8kW when the grid went out, and four 5P batteries fully charged. We have Savings mode on and this happened as peak rate was just starting at 4pm. So now the weirdness: the solar stopped feeding anything, zero output but the devices were all healthy, and all house load was fed by battery discharge. I called Enphase support and I got basically a reset command sent to the gateway. Nothing resolved because by the time all that happened an hour had gone by and the grid came back. Was really just a "control-alt-delete" response anyway I think. My suspicion is it's a fundamental issue with Savings mode which might ever so simply say that all loads must come from batteries during peak hours regardless of on/off grid and even if it means completely shutting off abundant solar to loads. Is solar simply for export only until the batteries are exhausted down to the limit during peak hours for Savings mode even during grid outage and solar is being completely wasted? Not going to get that answer from support. Anyone have any experience with this?
