Inverter Questions

[cmillsap]

First off, you shouldn't let your batteries discharge too deeply. 51% is too low. This shortens the batteries life.

The generator provides AC voltage to the inverter which in-turn converts the AC to DC and charges the batteries.

When the Cummins engine is running, it turns an alternator which charges the battery banks directly. The inverter is not used in this circuit. So, No, the inverter doesn't need to be on when the engine is running to charge the batteries.

I would turn off all battery master switches when storing the coach for long periods without shore power. But I would start the coach weekly to keep the batteries charged.

Also, if you are storing your M380 in Monson, MA this winter, you will need to winterize it especially if you are not hooked up to 50A shore power. Frozen lines and busted water heaters creates a major catastrophe in any motor coach. Your manual will show you how to winterize it. If you don't have a manual, there should be one available here in the "Documents" section of this forum.
