OK, I've got the 450 Amp hour figured out. Since it's a 12-volt inverter, and I'm wiring 2 - 6 volt batteries in series to get the usable 12 volt supply, it does not increase the Amp hours. Using 4 batteries doubles my Amp hours to 450. Each set of batteries will add another 225 amp hours capacity.
I still don't understand the AC1 Breaker though. The default is 30 Amps but is configurable between 5 and 30. Apparently, there is not a 50 amp option.
Low Batt Cut Out: In the manual it shows the settings to be 10.5V, 10.0V, 12.0V, 21.0V, 20.0V, 24.0V. I understand I don't want to discharge too low. So the default of 10.5 is too much?
