that 6.5a at 120v translates to almost 800w , thats going to be the compressor start up surge
our residential ridge runs 90~100 watts and we also have the Tripp-lite PV1250
inverter
it will power our 1100 cooking watts (1650watts consumed power) MW
but i prefer to use the generator when using the MW, unless its late at night no-genset hours
that is one very well built inverter
