I know generators have been talked about to death on this forum. I am just trying to reconcile some things I've read here with what the user manual and dealer told us. We have a Firman Inverter style generator and two 12 volt batteries. Using the generator to charge the batteries through the shore power cord takes forever. Not literally but I hate the generator sound! The book and the dealer both say we can charge the batteries using the DC cable and hook directly to one of the batteries. We've done this and it does charge the batteries a bit faster not going through the shore power converter.
I think I've read here (or elsewhere) that charging that way causes damage to the batteries. The dealer says that the voltage is controlled by the inverter so that is not an issue. I'm truly just a battery power dummy and can't figure this out. Wouldn't the DC cable method be similar to a portable solar setup?

All thoughts are welcome. Thanks.
