i was wondering if there would be issues of adding two six volt batteries independent of the factory twelve volt set up. I want to add the six volts and charge them using a generator , until I can get solar set up and run cable to the inverter only and plug in the shore power cord to the inverter. thoughts ?TIA, Joe

Not sure what you mean by independent. If you are connecting all batteries together.. here are some other posts.Add 12v to 2 6v12 and 2 6v 2010

Sorry, I mean to not have the six volt batteries hooked to or connected to the trailer in anyway other than through the inverter and power cord

What you wish to do can be done. However, when drawing on the inverter, it would be better for it to draw on all possible batteries. Add a switch similar to this one from Napa

Thanks for the input, Don. Could you please elaborate re the inverter and switch ...

Joe,I think you're mixing "inverter" with "converter". Your onboard converter uses shore power to charge batteries and provide 12 V power. An inverter takes 12 V power from batteries and provides 120 V AC.There are no issues about leaving a 2 x 6 V battery set independent of the trailer's original 12 V battery. The question arises, why? If you wire the new 6 V's into the RV's charging circuit, when you're on shore power they get charged. Also, connecting the 6 V set into the existing 12 V power distribution, the whole battery bank nets you more power. If you want to use the 6V's as an emergency backup, wire all the batteries together and use a main battery disconnects switch that has four positions: Battery 1, battery 2, Battery 1&2, off.

^^^^ yes, although there are probably a few other items on that branch circuit.

Hi,

I have two unequal battery banks. I put the switch(es) between the banks and the inverter. I can use either one, or both to power the inverter. I can use one bank and charge the other. It is cheaper and more flexible than an A,B,Both,Off type of switch.

And yes, you can turn off the converter at the breaker panel. Mine is a plug in unit so I simply have a default of unplugged. That leaves me with only the fridge to move to propane.
