Bill,

What are you going to use that inverter power for? Big difference if
your trying to drive a 2000watt microwave for 10 minutes once a day,
vs. some other use.

The 2000watt inverter option on my Beneteau 393 is powered by (2)
200Amp Hr Deep Cycle 12V, total 400AmpHr. I figure if I run the
Microwave for just 6 minutes, I barely have enough juice for the rest
of my energy budget for the day. That's assuming I can charge the
whole thing each day from dock power. Therefore, I am thinking of
removing the microwave and turning that area into storage.
