When I pulled in my doc today and hooked up the shore power as soon as I switched from my generator to the shore power I tripped the breaker on the main panel of the dock. It did not trip my breaker on the boat or the breaker on the power tower. After a bit of narrowing down I discovered that it was my inverter switc when I pulled in my dock today and hooked up the shore power as soon as I switched from my generator to the shore power I tripped the breaker on the main panel of the dock. It did not trip my breaker on the boat or the breaker on the power tower. After a bit of narrowing down I discovered that it was my inverter tripping it.

If I leave my inverter switch off on my panel everything works fine… As soon as I click the inverter switch it blows the breaker. How do you test the inverter to see if it’s bad or not? Can they be repaired or is it better to just buy a new one. As you can imagine I would prefer not to have to purchase one if it can be repaired etc.

I’m just not sure how to check it or test it to confirm that it’s really bad or not. It does not trip anything when my generator is running well underway. And it hasn’t had any problems at the marina where I keep it. I’m on a trip and pulled into a new marina for a week today and that’s when I noticed a problem.

Any feedback or thoughts would be greatly appreciate it thank you all so much!
