Problem with GFCI breaker popping on my Xantrex inverter
I have a Xantrex SW2000 12V inverter that the GFCI breaker keeps on popping every time I switch from generator to inverter via my transfer switch (TS-30 power switch). While looking at my main panel, I discovered that my neutral to ground bonding wire was previously disconnected by someone else. Attaching the ground wire back to the neutral bus instantly causes the GFCI breaker to pop. I am at loss to explain why this is happening? Checking the ground wire to neutral bus with a volt meter, I am not seeing any voltage. This problem started up about a year ago, with the GFCI popping whenever I switched from the generator to the inverter. The system had previously been working flawlessly for 5 years.
