i have (5) AGM at 135Ah (each) total = 675 amphrs
and i still prefer to run the generator when i use the MW
and my use is typically 1 min at a time , except for baking potatoes
which it is 6 or 7 minutes
your looking at 34 ? amps per battery
34 amp minutes per battery 102 amp minutes total use or 1.5 Amp hrs
and that does not include purkert effect at that rate your batteries are good for 2hrs max to total discharge aka dead
technically by the listed specs, yes your those batteries will support that when new and fully charged
how will they act after a couple of week ends doing that 3 times a day
IDK
