    2910BH tv wiring mystery load

    Hello, we recently picked up our new 2910bh. I plan to add solar and a small inverter to power the tv and misc plug loads (no microwave). So, the solar went well, MPPT charger + 100w panel, we'll see how far that gets us. Now to the inverter. I have an old 600w sine inverter that I was going to reuse. I wired it to the load center to the gfi circuit, turn off the breaker, and that works great. But unfortunately the TV is not on that circuit. Actually nothing built into the camper is on that circuit, it's just for the plugs. With the exception of the outlet behind the TV and the one in the entertainment area behind the radio. The outlet nearest the radio is on the microwave circuit (I can also power this fine with my inverter) and the TV one is on *one of* the refrigerator circuits (it's 50a). My inverter trips if I try to power it (again all breakers turned off so it's just that circuit). It's not the TV because I can plug that directly into the inverter and it uses less than 20w. With the tv unplugged, I measure 10 ohms DC between hot & neutral on this circuit. I unplug the refrigerator plug from outside and still measure 10 ohms. That seems like maybe the water heater element, so I unplug that and no luck, still 10 ohm. It's not the converter, because I can see it and the circuit it's plugged into and it's not this one.

    So, this leaves me with 2 questions: 1) why are there 2 refrigerator circuits (15a)? and 2) what is the mystery load on the TV circuit?

    What am I missing?

    Thanks

    10 Ohm would be close to 1500W. Fireplace? Whatever it is will be producing some heat.

    Mystery solved. The clue was in my question. Two refrigerator circuits means two refrigerators. The outdoor kitchen has a small dorm mini fridge. I unplugged that and everything is happy. Too bad my inverter can't start it because I measured it running and it pulls less than 50 watts. The startup current must be too much.

    I was able to swap a few circuits around and now the inverter will power only one of the 50A phases with the converter being on the non-powered side. This way I don't have to remember to flip any breakers off before turning on the inverter. This gives me GFI, both refrigerators, and microwave on the inverter side and the other side has the AC, water heater, and converter. Someday I can add an auto transfer switch and larger inverter and make it really nice but this is good for now. It would be nice if they added an inverter prep from the factory like the solar prep. That made it very easy to add the panels. Without that I had to figure out the ac wiring and move a few circuits around to make it inverter friendly. And more descriptive labels would have been nice, a label with "Outside Refrigerator" instead of just "Refrigerator" would have avoided this confusion.
