Yes Solar CowboyZ can fix these;Contact Kristina # 530-273-4895.
If the Inverter is not repairable due to catastrophic failure/burned PCB then we can get a RFB unit as a direct replacement(no need for any re-wiring etc.).

I believe this indicates a grid voltage out of tolerance. The inverter has correct grid voltage and frequency to the grid terminals and is a model that does not include the fuse. This inverter is on longer supported so I can’t get a repair. I have previously changed out the firmware and used the reset sequence.I tried resetting the inverter by cycling power for several minutes and using the ENS1/ENS2 procedure. No change in status. Does anyone happen to know of any other method to reset this inverter? Otherwise it becomes a boat anchor.Thanks,William
