Power off the grid - Solar?

We can easily make a 3 day weekend on our (2) 6V 235 Ah batteries running LED lighting and little concern for conservation. With you being (2) days a week max you should be fine with a battery set-up like this and the solar set-ups recommended by those above. We bought an LED TV from Walmart, many of them actually run off 12V power through a transformer in the cord. We cut off the transformer and hooked directly up to our 12V battery power. Based on your intended usage, I see no need for a generator. You should be good for 2 days even without any solar input while you are there, then you will have a week of solar recharge to top back up again so a few cloudy days should not effect you.
