Xantrex Freedom 458 20D tripping

Good Afternoon,
Why does my inverter "trip" when running two appliances? I try to run a coffee pot and griddle, and my inverter trips. This causes the refrigerator to turn off as well. Is that really too much draw? It is quite annoying. A circuit breaker in the coach has never been tripped. It is always the same branch circuit on the inverter that trips, the top one. The bottom circuit has never tripped. I have read that maybe the fan is not coming on or maybe not enough ventilation in the compartment. Before I start troubleshooting, is this normal?

Thanks,
Todd

    Sorry, why would you run through the xantrex whilst on shore power?


    I don't seem to have a choice. Like another commenter said, AC runs through the inverter while on shore power. Inverter will only turn off when not plugged in to shore power.

    The circuit coming from the inverter (even though it's voltage being passed through from shore power) is still passing through the circuit breaker in the inverter. You are overloading that breaker.

    The refrigerator element, griddle and coffee maker are all resistive (high current draw) loads. You need to run the refer on gas (or move to another circuit) and also move one of the other appliances to a non-inverter circuit.

    Depends on how it is wired. With the built in "pass through"/ATS, some coaches just rely on the on-inverter breakers for circuits that can be powered by the inverter.

    Find an outlet or wire one that comes direct from the main 120 VAC breaker panel rather than through the inverter to power high-amp appliances.

    Hi,

    Next time it trips wander around the rv and test every outlet. Seeing as the fridge is involved, count 325 watts for running that to any other base loads.

    Why wouldn't a circuit breaker in the coach trip? Why the inverter breaker? So do you think the inverter is fine?

    By the way, each one of those appliances can draw as much as 100 AmpsDC.
    Running both on the inverter will drain your batteries very quickly.
    Now the above statement is no good if you are connected to shore power, then the AC is only a feed thru. Meaning the AC goes into the inverter and then back out to an Inverter circuit breaker panel. In this case the inverter is not turned on, but only allowing the ac to pass thru it and onto the ICB panel.
    Then it could be a back CB, bad connection on the outlet or and a overloaded circuit breaker.

    You are overloading one of the circuits. Move the coffee pot to an outlet on the other side so it may be on the other circuit.
