Our utility (SCE) has placed temporary diesel generators in our neighborhood to provide power while their underground cable repair project runs over schedule. The generators have been running for three days now. We have no problems with household power or with any of our appliances or computers, but I noticed that our solar PV production was down by almost 50% during these three days.
I checked my TED power monitoring system and noticed frequent on/off transitions in solar power generation reporting. I checked the solar inverter and I see intermittent drops to zero power production in full sun. TED shows normal build-up of PV power generation until between 10:30 am to 11 am, it differs on different days, and then it goes into on/off cycling for seemingly random time periods of up to 20 minutes to as little as a minute. The household voltage is also much more variable than usual, between 118 V and a low of 111 V.
My question is whether running my solar inverter during this temporary period is damaging to the inverter, or even for the solar panels. Also, could a varying voltage cause problems for my LEAF onboard charger or for my AV Level 2 EVSE during charging at night?
Thanks for any thoughts you folks might have.
