How do you run the microwave and outlets without shore power? What is an inverter?

normally, you'd need an inverter generator.

but if you have a big battery bank and a big inverter, you might be able to run the microwave for a few minutes.

to run the outlets, the inverter would have to be wired into the RV's 110v AC electrical side. this would not be an easy task.

an inverter inverts 12v DC battery power to 110v AC power.
most just use an inverter plugged into the 12v cigarette lighter socket and plug a tv or electronic devices into the inverter.

I have a 1000W inverter wired directly to the battery bank then to a transfer switch in my system. The inverter transfer switch provides power to the microwave circuit, the outlets for TV etc. but NOT the AC, HWH, Fridge or converter.

As for running the microwave for a "few minutes". In reality I could run the microwave for an hour or so before running down the batteries. I run a panasonic true inverter microwave set to 50% power (1000VA) when using the inverter. Draws about 90A. On a 220AH battery bank that translates to about an hour of run time accounting for the AH on a high draw. Typically it is used for a few minutes at a time to warm vegies, DW tea, my coffe, etc. or warm up a meal at a rest stop.
