What are you planning on running with all that solar? With my 2 cheap batteries my 136 watt solar panel can charge them up by 10am or noon if I'm in the woods on a cloudy day and they are usually down to the 12.6 range after running the LED lights and 12 volt controlled fridge and heat plus charging the phones or tablets or whatever small draws over night. If I'd spent the extra money on the golf cart batteries I'd be using 15% of their capacity instead of the 25% capacity of the cheap batts I'm using. In my application, mostly dry camping with the wife and two kids with no computer or TV and I don't even bother bringing the generator anymore, I don't need the more expensive batteries.
