ok, there is an "easy peasy" way to run a microwave on a 1000W sine wave inverter. Been doing it for a decade or more. solution: Buy a panasonic true inverter microwave. rather than cycling between 0% and 100% power on reduced settings it runs continously but on lower power. the 50% power level easily runs on our 1000VA inverter, draws about 850W on that power level.
At 50% power level things like heating water, cooking frozen veggies etc. takes about 25-30% longer than 100% power.
Nice thing is we can use the microwave w/o having to go out and start the generator.
Now for the downside. If your battery bank is a PAIR of GC-2's, likely the inverter won't like the voltage drop if the batteries are below about 80% SOC. four GC-2's and your good down to around 50% SOC. Here is where a pair or even one 12V outperforms the GC-2's. The 12V has WAY less internal resistance and hence voltage drop. and a pair of 12V wins even more with the batteries splitting the current.
