Inverter resets 2 days in a row

solar_dave

I have had 2 inverter resets 2 days in a row midday. I do notice a variation in the utility voltage at the time like maybe the utility is hammering substations midday but my one second data acquisition never shows voltage below 120 volts.

Could it just be bad utility power for a split second?

Re: Inverter resets 2 days in a row

it could be the utility adding a generator onto the grid and it is slow enough in locking into phase that it is throwing your system for a loop. i'd call them with this concern for it certainly isn't the fault of your equipment by that chart.
