Proposed Solar Install thoughts

Hi 6 x 6 = 36 volts.

If you stick to 12 volts with 6 six volt there is only one way to wire them to be balanced. See method #3 here: correctly interconnecting multiple twelve volt batteries

Thanks PT. Totally missed the battery bank type in his post. IMO, if you haven't purchased the batteries yet, I might go with 12V for less voltage drop under heavy loads (ie the A/C) although 6 6V's will work well too. That said, don't skimp on the wires. I would not go less than 2/0 for the interconnects and 4/0 for the inverter wires. If your inverter manufacturer says go bigger then go bigger. Keep the inverter to battery run short (under 6ft). If you need to go a long way from inverter to batteries, double up some 2/0 to a bus bar near the batts then go 4/0 from there.
