Microwave and TV Power - Need help troubleshooting

I'm getting power to the MH. The microwave and both TV's in living room and bedroom went completely out. I was plugged into shore power when they went out.

Any ideas/advise?

Thank you.

    You were plugged into shore power when they went out, so what do your house batteries have to do with it? Weren't the appliances running directly off the shore power?



    Yes, I was plugged into shore power. Sorry for the confusion, I am not knowledgeable with the electrical on the MH. We've noticed our interior lights started dimming a few weeks ago and the last time our lights did this a couple of years ago we replaced the house batteries and it fixed the dimming lights. Just thinking of other possibilities but like I said I'm not knowledgeable with the electrical.

    Maybe area power outage? Anybody near you have power?


    There is no power outage.

    Agree. Microwave runs on 120 vac, not battery. Look for tripped GFCI outlet. Or if on 50 amp service, check to see if you lost one leg of the 50 amp outlet.


    The GFCI outlet is completely out, no power.

    Welcome to the forums!

    Is the RV a 50 amp service? YES

    Do any of the power outlets work? YES, SOME WORKING OTHERS ARE NOT

    Is the battery bank being charged? YES

    Do you have a way to measure the voltage at the outlets? (for example, a kill-a-watt meter)? YES

    You've done just about everything you can do. I sure as hell am not going to advise a novice to go behind the circuit breaker panel. But that is where I suspect the problem lies. You need someone experienced to help keep you from being electrocuted.

    The charger in the inverter? Sure. Get out the voltmeter and check your batteries.

    Yes. If you have a pass through inverter then it could also be it's input CB as well as the related panel CB.

    Recommend you get the batteries charged while finding the problem.

    Always helpful to post what you have like: mfg model xxx charger/inverter yyy watts etc.

    A few (nutty) inverters are hard wired in place and the power flows through the inverter first--I think this is a stupid design choice.
    I wired my prosine that way to act as a power minder but it was easy enough to verify with a voltmeter at the pedestal if it was refusing shore.

    And I've never heard of an inverter with breakers on it.
