Inverter outlets have no power

This morning we had a small electric heater turned on to remove the morning chill and was plugged into one of the outlets controlled by the inverter. We are plugged into shore power, so without much of a thought, went to use the microwave, also on the inverter circuit, all outlets went dead. There is a gfi outlet near the bath sink, it did not trip, and will not reset. Checked for a tripped circuit breaker, none found, no blown fuses in the fuse box. The inverter continues to charge the battery banks, current is good through the inverter class t fuse. There is a gfi outlet in the engine compartment, it works fine. This is a 1999 Monaco Diplomat DP. Every thing I've checked, checks out fine. I replaced the bathroom gfi outlet, still nothing. I'm at witts end trying to figure this out. All suggestions are welcome. Thanks in advance.

    Hey, one of the games they play in the RV industry is "Hide the breaker"

    Another: Hide the GFCI

    Just so you know

    Glad you found yours.
  • My inverter has a 30 amp fuse on the output. It is a plug in fuse, much like would be found on a air conditioner disconnect switch, and needs to be pulled out to replace it.

    My buddy's Country Coach as two circuit breakers mounted on the inverter.

    So you might find a fuse inside the inverter box, or a circuit breaker on it or nearby.

    Let us know what you found!

  • Circuit breaker on inverter, on the 120v pass thru side
    Or
    The inverter transfer switch/circuit

    You over loaded the circuit

    I did that to a Freedom 10, inverter/charger, burned out the pass thru transfer relay, using an extra battery charger on the circuit
    Mine was a slow dead from cumulative over heating

    Thanks for the suggestions, I'm blind in one eye and can't see out of the other. I never saw, though I looked right at them, 2-20A push type reset breakers. Everything works again, like it should.

    Three options.. I've seen 2 (one about an hour ago) and read of the 3rd.

    First.. My layout, Inverter is a "pass through" model, feeds a sub panel that's near the main panel.. I tripped one of the breakers in the sub panel about an hour ago.. Noticed it right away, re-set and re-configured so Dinner was done on time.

    The one I read about.. in some cases the "Sub panel" is built into the Inverter, same thing, often Post type breakers (Press to reset) though instead of the more common switch style.

    Option 3: This too happened to me plus I just this morning read of it happening to someone else... Bad conneciton in the junction box where the inverter is connected.


    My inverter monitors input and output voltage and current or 12 volt voltage/current and 120 volt output and current or.. Well several options.

    It showed proper power coming in
    It showed proper power goign out (only no current)

    But no power at outlet.

    Opened the junction box and prounced a loud AH-HA.. Fixed it, and joy was had.
  • just a quick thought i have two breakers on the inverter--one works with the microwave plug---could your microwave also have a breaker?
