Steps you have taken to resolve problem:
1. Reset by turning to "off."
2. Did manual start. Unit ran for 30 seconds, shut down and returned "overvoltage" error.
3. Repeated steps 2 & 3 with same result.
4. Reset generator, set to "auto."
Hi...i am a new user here. As per my knowledge resetting it and putting back in auto is not a good idea if something is really wrong and for some reason you lose power. You don't want there to be a chance that the generator would be connected to the loads in the house like that.
