I have 2 solar panels @ 150watts each,I have 2 12v batteries @ 175amp hours each, my solar generator has an inverter that is 5,000watts peak and 2,500watts continuous. I am powering a small cabin. Refrigerator, lights,TV,small appliances, computer,etc. What way would be the best way to hook up the batteries to give me the maximum run time with what I have?
