I returned after a weekend away to find that our inverter would not provide any AC output nor will it charge the batteries. The inverter had been off, as I had no necessary loads while we were gone. There are no error codes or warnings on the Mate, but it does indicate the zero AC or DC output. However, all controls seem to be working, including turning on the inverter, which results in a hum and the appropriate green lights, but no voltage. I have two breakers that are paired to allow AC input from the generator to bypass the inverter, and when I switch to bypass, then I have power at the main panel, but when I switch back, the generator power is not passed on to the main panel.
Any ideas? Is there a function like this in the programming for some reason, that I might have missed in the manual? Any other troubleshooting suggestions?
