Yes, I am running 6 deep cycle marine and 600 watts of panel and never have to start the (12v) generator except if I get a couple cloudy days. I use my laptop, run the radio or TV, lights, microwave, fridge on 12v, just as one would in a normal home. And I could actually get away with only 4 batteries.
As you know, there is a fine line between battery/panel ratio. Too much battery and they do not fully charge during the day. To much panel and you are wasting free energy. So there is a balance to it. I would suggest to the OP for his rig 4 deep cycle marine batteries and 600 watts of panels would be a good balance.
How much area does 600 watts of panel need.
