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?
Your charger is capable of using up to 30 amps of power. Whether you are on 50 amp or 30 amp is irrelevant to the charger, it will only ever try to draw 30 amps at the most if you set it at 30 amp. Leave this setting at 30 amp. The only time you should change it is if you are plugged into something less than 30 amp power. In this situation the charger could potentially call for up to 30 amps for the charger to recharge a depleted battery bank. If less than 30 amps are available, you will trip the breaker. In this case, set this number to whatever amperage you are plugged into (15 amp or 20 amp).
The low battery cutout is what tells the inverter to stop inverting if the batteries get too low. There is usually a time associated with the voltage. For example if you set this at 10.5 volts and the time is 10 seconds, the inverter will shut down if it measures 10.5 volts or less for more than 10 seconds. The reason there is a time associated with this setting is because the inverter will initially draw down the batteries to get an AC load going (surge) and then settle into a more constant voltage. You do not want this initial surge to shut your inverter off. As the inverter draws power from the batteries, it will also make the batteries read lower voltage than they actually are. Once the AC load is done (ie the microwave or hair dryer is done being used), the batteries will rebound some to a higher resting voltage. All of this is a long winded answer to say the default setting of 10.5 volts is good.
