I have 6 year old Powerwall that's connected to a non-Tesla PV array. We've had a couple of utility outages the last few weeks and I noticed that after the power goes out the PV stops production even on a sunny day. PV production starts back up when utility power is restored. I know this isn't by design so wondering if anyone out there has seen this and has a (hopefully) simple explanation/solution. I've reached out to the local Powerwall rep and they agreed the PV system should re-start production shortly after utility power is lost. Unfortunately they want $300 just to schedule a tech to come out and check it (it being something they installed themselves).
