Sure it will run your micro, it will just deplete your battery's.
Do the easy math. Theoretically here ya go. Not figuring the inverter loss while operating.
2 x 100ahr lithium batteries equals 200 hrs total availible at 100% discharge which you dont want to do.
I think 90% is acceptable but not recommended.
So you have 180ahrs availability right?
Microwave will draw 1350 max at 120vac still with me?
Inverter is rated for 2k so your good there.
Micro will draw max 11.25 amps at 120vac.
Inverter converting to DC you will use 112.5ahrs of battery capacity using the micro for 1 hr. And you only had 180ahrs.
So using the micro for like 15 minutes will deplete your battery's approx 28ahrs or so which would be about 15% capacity.
Now you will need a way to recharge those battery's to get back to full state. Either by battery charger , solar etc.
Good luck and dont burn the popcorn.
