Thanks all for your input/suggestions! I decided to go with the Grape Solar COMET 12/24-Volt 40 Amp Solar Charge Controller. I want to keep things simple and inexpensive. (2) 100 watt panels is all the space I have on my 17' roof, and should provide plenty of power to my little trailer.
Last Summer I ran just fine on the Harbor Freight 100 watt Thunderbolt system. Since then I've upgraded from dual group 23's to dual 6 volts, therefor needing to upgrade my solar setup.
I ran my heat and lights for about 18 hours bringing my batteries down to 81%. One 100 watt panel had them back up to 100% in just under 3 hrs with the most intense sun hitting it in the last hour.
Again, thanks for all your help! Now I just need to figure out the best way to mount them to my roof :)
