On our rigs, the Freedom inverter contains an additional transfer switch (battery vs shorepower).
So shore power passes through the inverter on the way to the coach 110v outlets.
If the breakers on the inverter do not like the power draw, they will pop.
If the shore power is routed around the inverter, then the outlets will not be able to receive inverted power.
If a larger breaker is in front of the inverter at the breaker panel, the inverter will still trip.
I suspect the only solution is to modify the inverter box itself with a larger breaker?
