Thanks for all the great responses.
Unfortunately the Samsung mw620wa model is no longer available, parts only.
Do you have a model number for either of your Panasonic Inverter microwaves ? My initial search found the smallest one to be 1.2cu ft which would correspond to 1200 Watts. That is probably not it.
Other option is to go with a good inverter but the distance from the battery bank to the converter would necessitate access through the floor and a 4/0 cable to minimize voltage drop. Not my first choice.
Mine is the 0.8 cuft, 950W model. it fit in place of the exisiting microwave in the trailer.
I ordered it from Amazon, since most stores didn't carry the small one.
here is a link to the one I bought

The 950W is the output power of the magenetron, actual VA consumption is around 1200VA at 100% power IIRC. When I got ours I hooked it up to my kilowatt meter and measured the VA consumption from 10% to 100% power to determine (a) actual VA draw at 100% and (b) VA draw at various power levels to determine the max power setting I could use with my 1000VA sine wave inverter.
50% power level works very nicely with my 1000VA sine wave inverter.
One thing to keep in mind. Virtually ALL appliances you buy will in almost all condition never draw the nameplate power, but something less. The reason is that for U.L. testing the mfg must state the absolute max power draw under worst case condtions. Designed products that needed to meet U.L. when working and one thing a mfg never wants to do is UNDERSTATE the max draw. So typical operating condition with a line voltage near nominal will normally be less than worst case draw.
