No power from shore or generator, ok on inverter, need help

Have you checked the breakers on the inverter? DW would try to run our microwave with the space heater on. No matter how many times she tried it would knock to power off. The inverter was under the bed and I had to remove a cover to get to it. After a few times I installed a little door to get to the two breakers on the inverter itself.

Good luck....Let us know what your fix is.
