Interstate Batteries tied together for 24vdc for my PV system, I call my small solar structure. Interstate Batteries are great for Photvoltaic (PV) systems because they are a very reliable battery, available in most cities at any Interstate Battery location and are easily configurable to most PV arrays. My PV array was a 12vdc system until I changed it to a 24vdc system to accommodate the stronger 24vdc pumps required to pump my solar hot water up the hill to and from my home. The Interstate Batteries I chose were the 6vdc model, U2200UTL Deep Cycle.
