I have 300 watts of solar and 4 X 6 volt batteries. I installed a separate PD9260 in the compartment next to the batteries, hooked up with the proper sized cables. We dry camp almost exclusively, use a toaster, microwave, coffee maker with a 2000 watt PSW inverter. We can stay out as long as the water holds. When camping in the forest I run the genny for a couple of hours in the evening directly hooked to the stand alone charger.
I have left the stock charger alone, only added a separate breaker to turn it off.
