Wire size from batteries to inverter Question.

[Flumes]

I have 6 - 12volt batteries that are 105 Amp-Hour each. I would like to make a 24 volt battery bank. I would like to wire 3 pairs of batteries in series, and then parallel them before the 1500 Watt/24 Volt inverter.
Questions:

Am I right to assume this will equal 315 amp hours total at 24 volts to inverter?

The batteries have bus bar connectors to make series connection for 24 volts. What size cable would be needed for the parallel connections and the connections to the inverter?

Should the charge controller wires be hooked up to the opposite terminals of the load side of the batteries?

Thanks in advance

Yes that would be 315 AH @ 24 volts.

80 amp minimum requirement is 4 AWG up to 15-feet.

Thanks Sunking. Much respect.

I have a bunch of 2 AWG that I was hoping would be adequate and am happy to be able to put it to use.

Too bad you already have the batteries and will be having to wire 3 strings in parallel.


When they prematurely fail, check in with us about a better way to wire with 6V batteries and fewer cells to check water levels on.

Thank you for replying Mike. Yes, I understand the parallel configuration would be best avoided.

(I acquired a remote bush camp that needs alot of work. Before I invest alot of money into something I'm not sure I am going to enjoy, I am trying to make use of materials that I have available. The batteries were freebies.)

When this battery system dies, I will take your advice and go with a 24v system made up of 6 volt batteries in series.

Thanks for your advice
