I have a solar array with 2 Sunpower/Sunnyboy inverters model SPR-6000m. One of the inverters has an error that from the manual (see pic) is "Inverter Interference". The indicator lights that blink match the pattern in the attached pic. The display also says "Disturbance OFFSET". I contacted the installer and they can't come out right now because "grid tied solar systems aren't considered an 'essential service'"! I contacted the manufacturer and after about a 45 minute call, which basically ended just being "turn it off and on again"! (ARRG!) ended up with the same problem.

I tested the voltage on the breaker attached to the inverter and it was right at about 120-121 volts to neutral and about 240-242 across the hots. I also pulled the cover on the inverter and double checked the voltage there and it matched. The input voltage from the array was about 410vDC. The other inverter is doing fine, no issues.

Our governor just extended the stay at home order until May 4, meaning I'll lose out on an entire months solar production.

Is there anything I can do to fix this? Parts needed? I'm a pretty decent electrician ( but not licensed), still I'd like to at least try to diagnose this (and hopefully fix it) without losing a month of production.
