Motor31,
For clarification, if you have the inverter option, AND the generator option (not just the gen prep), the power system monitiors the shore power and batteries to autostart the generator when necessary/required.

The Onan Generator also has an autostart feature that is connected to the thermostat so it will start (regardless of battery level) when the thermostat calls for AC or the heatpump.

It's a pretty cool system. With shore power, the system distributes AC power to the coach and charges the batteries. When the shore power is lost, the inverter converts battery power to AC power to run TV, lights, etc. When the batteries become low, the generator auto starts and recharges the batteries. When the batteries are recharged, the generator autostops. Once AC power is restored, and the batteries are recharged, the Generator autostops as well and stays off with shore power available.

We have the inverter and gasoline generator on our Elite Suites. We used a portable generator on our Mobile Suite for tailgating at sporting events. We like the option to have AC power (via the inverter) when minimal AC is required and 'full power' for items such as both ACs when required via the generator.

I hope this helps.
