Howdy, Leisurepaw.
I have used a GE Spacemaker and a Sharp on a 2000 watt inverter without any problem. I can't remember how long I did run the microwave on the inverter but I was cautious. I reheated some frozen spaghetti sauce and I think that it took 10 minutes.

Hi Leisurepaw,

We have owned nothing but Sharp and have run them a lot on the inverter. Not long periods of time at once but many shorter intervals. Never have had a problem.

Your biggest potential problem is the three batteries.  Most microwaves draw at least 1000 watts, meaning a continuous load of around 90+ amps from the batteries.  Even a few minutes at 90A will drop the voltage severely and may trigger the low voltage shut-off on the inverter.  New batteries will probably handle it, but aged or abused batteries may not.

For your purposes, a smaller (lower power) microwave is better.  Or increase your battery bank to four batteries, which spreads the load better.

An electric coffee pot is a much easier load to handle than a microwave, but that won't pop your corn for you.  :D
