Hi all,

I cant quite wrap my head around how to wire 4 12volt batteries together to make a 24 volt system, but I found this wiring diagram online and want to see if anyone for sure knows if this is correct!

Im almost finished with this solar system!

thanks so much!

It seems correct for my limited knowledge.

Connecting negative to positive combines the voltage to 24. Looks like two groups of those,  connected together.

Well, I found more guidelines about wiring in series/parallel and Im seeing this come up a lot:

Wire the series first, then wire the series sets in parallel.

The leads to inverter are attached to opposite corners of the bank. Make cables the same length.  

When you draw it, put a dotted line around the series segments, this will help you visualize it.

So the original image I attached doesnt follow those guidelines quite right.

This new attachment does, but uses 6 volt batteries.  substitute 12 volt batteries and it would show how to get 4 12 volts batteries wired into a 24volt bank
