The Transfer Switch Saga - post mortem

We took out the blown transfer switch. Seems we welded the generator relay contacts when the gas gen was plugged in improperly, so when you shut off the gen, and enable the inverter, the gen never disconnects. Poof, fried inverter. Self inflicted, non-warranty issue, But the good folks at Back Woods Solar have a customer returned unit like new at a deep discount. Thank you Scott!
