I actually ran one (650 watts or so) for about 5 yeaqrs off an inverter.
Drew a little over 100 amps. Used to start an engine to keep the battery
draw under control. Did not really have a bank big enough to sustain the
current. Actually worked well. Run one at fast idle for about 15 minutes
before breakfast and we got both microwaved stuff and the coffee pot. Big
alternator on one engine.

for a small microwave for a boat, what wattage inverter do u need and
what will
it draw in terms of amps to start and run the microwave?
I picked the most efficient 700 Watt microwave I could find at the time.
Through the inverter it draws 84 Amps DC. A 1000 Watt inverter might
handle it, but it would be close. I have a 2000 Watt Heart
inverter/charger and its overkill.
