Circuit breaker on the inverter is one of those little push button styles. I’ve tried pushing it in several times but it never feels like it’s tripped. The panel doesn’t give me +- on the V input. Just says 12.6. The control panel allows you to select which input you want to see and using that, it shows 0.00 watts output. It’s not showing any fault codes. When you turn it on with the shore power disconnected it shows the switch to battery power through its indicator lights. I’ll try the deal with shorting across the power connects with the power all disconnected. Any other ideas?
