Inverter powering only one outlet

Appears my inverter is powering only one outlet in my RV. The TV/DVD outlet in the living area. All outlets work on shore power. This just started a month or so ago. Any thought on how this could be happening?

Both shore and the inverter are distributing through the same AC wiring system aren't they? If that's the case, it doesn't seem there could be circuit breakers or wire issues. Either one of those would affect both shore and inverter distribution wouldn't they? I'm new to the RV world. Am I misinterpreting how the system is wired? I am absolutely baffled!


    NO.!!!

    shore power goes to the transfer switch
    from the TS it goes to the breaker panel

    then (1) 15 or 20amp circuit breaker feeds your inverter
    and only the outlet(s) on that circuit are powered

    are you sure everything else has always worked on inverter before
    that seems unlikely

    I hope not. Pass through rating on the 1000 is 15 amps. See manual section 3-14.

    Are you sure the inverter is hardwired for 120v ac? Or is it just connected to the batteries? See sections 2 and 3 in the manual.

    You need to trace the wiring, and post your set-up here, or it's anybody's guess what's going on. You mention a GFI, but where is that GFI??? In the inverter, or somewhere in the trailer??? At this point, I haven't a clue as to how things are wired up, and it appears no-one else does, either, including you. No room for interpretation here... we need facts, first.

    First: Factory inverters are often wired this way.. I assume in olden days (2 months ago) the invrter powered other outlts.

    On many inverters there are one or two circuit breakers... They may be hidden back around the backside of the RV.. You will need to check and if you find them one may be tripped.. The one NOT tripped feeds the TV.
  • Some inverters have a circuit breaker on it's output, and one might be tripped. What brand inverter is it, what brand coach?

    Normally if the inverter had been running several receptacles, say 2 in the kitchen, the microwave, and the TV area, then if those will no longer work on inverter power, they also would not work on shore power as well.

    Most RV's do not have all the receptacles hooked up to the inverter. This saves battery power, and only runs what you need to run, not everything. Each GFI connected to a inverter will consume about 6 watts per hour, or with the typical RV having 8 GFI's installed, about 4 AH hourly! This can take a toll on your RV battery supply.

    Good luck,

    Fred.

    You have an open circuit.


    X2, and I would start with that theory. Shut the power off, pull all your outlets and look for a wire that has come loose on the back of an outlet. They daisy chain the outlets so one bad wire can kill the whole chain.
  • I thought you said there was no power to the gfci? If that's the case, there should be no output whatsoever. Or is half the gfci, i.e; one of its two plug receptacles, working?
