Question about inverter. If connected to shore power does it(shore power) charge my house battery and should my inverter be turned off? The folks at the rv place have me all confused. I understand the inverter converts 12 volt to 110, and converter(sp) converts 110 to 12 volt for lights, etc. So I would think generally the inverter would be switched off most of the time. Is that correct? Sorry to be so long, any help would be appreciated.
