2008 providence 40e electrical problem

[a johnson]

OK...tonight, problem not sure where to start.

had microwave and TV on, then went to make toast. Everything turned off.

Here why I am stumped. The EMS panel shows power to everything.

Some 120v outlets work, washer/dryer works, fridge works.

what doesn't seem to work, light on fridge door, TV, microwave, outlets kitchen side.

here is where it gets interesting, everything works if I turn the inverter on. If I turn the inverter off, then the bank of outlets doesn't work any more.

I've reset everything, unplugged shore power, switched to genset and it's the same.

I'm not getting charging in the normal state either.

Any suggestions????????? What am missing?

Circuit breaker on inverter could be tripped or you blew out the transfer switch in it. Should be a reset on it.

Hi Aaron,

Reset the GFI in your bathroom and any other GFI equipped outlets and check the 120volt breakers.

found it. there is a breaker on the back side of the inverter which all those outlet go on. the input breaker was tripped.

now RV wiring 101. when you have shore power hooked up, shouldn't the inverter be bypassed?

[Gary RVRoamer]

The inverter is fed from shore power and has its own internal bypass system. When shore power is present, it internally bypasses itself but power still flows through its breaker(s) for those circuits that can be inverter-powered. Therefore the breaker on the inverter can trip before the breakers on the branch circuits. This usually happens when the total load (which is limited to 30A by the inverter) exceeds 30A even though individual circuits are all within their own limits.

Only some of your circuits are capable of receiving power from the inverter, so the others (washer, water heater, etc) still work.
