I installed 3X PowerWalls to a pre-existing (non-Tesla) grid-tied PV solar system on 17MAR22. Thru the end of June I have recorded 30 outages! 4 were self-induced “go offline”. Three were for “a few seconds”, which is consistent with our experience prior to the install. A couple appear to be legitimate outages ... but the great majority are of exactly 5 minutes duration, and occur in clumps of several outages over a few hours (always nighttime). I’m trying to understand what is happening, and am unable to find answers. As this group knows, PowerWall technical documentation is sparse to say the least.
I spent 28 minutes on the phone with a rude Tesla tech rep. I was told (A) the inverter was being kicked-offline because the solar panels were overproducing (Between midnight and 3:00 AM? ... Of course!) (B) My utility-installed net-meter was not regulating the voltage correctly, and I should contact them (Really?) (C ) When I asked if the Gateway monitors the grid frequency of the incoming AC current, I was told the frequency I use the Air Conditioners should not have any impact. Not a whole lot of help to say the least.
I’m guessing that either the incoming grid voltage or frequency is enough “off” that the Gateway is disconnecting from the grid ... and for some reason the Gateway is taking exactly 5 minutes to decide it is safe to reconnect .. I wish I understood more. Can anyone help, please?
