I am using AGM batteries the DEKA Unigy1 series 105AH 12VDC version. I want the weight to be in the center of the vessel. 4 of these batteries are the similar to 2 8D batteries. Hence the reason I bought the AC DC Inc 2 8D battery box. I have 8 of these batteries they are new.
Since I will initially start out with 200 watts of 24-28VDC solar and an AIR-X 24-28 wind generator into smart controllers to charge a 12-14VDC house bank. I figure I might be able to use a small 420AH house bank. However I'm prepared to go as high a 840AH's if needed.
