Pics. The following wiring diagram shows that the two 12v, 10a, 120w solar panels connected in parallel will charge the two 12v, 100ah parallel connected batteries as well as power up the ac load through batteries and inverter during the day in normal sunshine. Multiple batteries and solar panels can be connected in series, parallel or series parallel.

Four 1.2 volt 2,000 mah wired in parallel can provide 1.2 volt 8,000 mah (2,000 mah x 4). The following wiring configuration requires four 6v batteries. But there are a few ways to do it wrong that i'll go over.

But what happens if you wire batteries of different voltages and amp hour capacities together in parallel?

The purpose of this wire is to balance the voltage drop evenly across both batteries and each wire during charging. Say you have 2 x 100 watt solar panels and a 12v battery bank. To wire this system you will need 2 sets of the system described in connecting two 12v batteries in parallel. For example if a 3v and a 9v battery were wired in parallel the output voltage would be 6v ( 9+3 divided by 2 ) however the current will be total amperage of all.
