I have 8 - 2 volt 362ah batteries for a solar bank. I would like to use all the batteries with a 12 volt charger/inverter. My question, can I connect 2 of the 8 in parallel and the remaining batteries in series? calculation: 8 batteries all equal in age and size - 2 volt 362 ah 2 in parallel = 2 volt 724 ah 6 in series = 12 volt 362 ah. Parallel Wiring: Parallel wiring, on the other hand, involves connecting multiple batteries side by side, increasing the overall capacity. This means that the voltage remains the same, but the system can draw more current. For example, connecting two 12 volt batteries in parallel will result in a 12 volt system with double the amp-hour capacity.
Battery bank wiring matters. It matters how a battery bank is wired into the system. When wiring a battery bank, it is easy to make a mistake. One of the most common mistakes is to parallel all the batteries together and then connect one side of the parallel battery bank to the electrical installation. As indicated in the image on the right.. To wire this system you will need 2 sets of the system described in "Connecting two 12V batteries in parallel. Connecting two 12V batteries in parallel." Ensure these batteries are all of the same capacity, voltage, age, type, etc. Wire two of the batteries as described above, then do it again with the other two batteries.
