Battery wiring diagram

[Slider]

Guys,

I have seen a link to a site showing the best way to wire batteries. Anybody have that handy?

I have 8x12v batteries that I want to wire in 4 strings of 2 batteries to make 24v (no need for 48v as its just for lighting and the batteries are free)

Where should the inverter be connected to in the string?

Thanks...Kent

8x6v would be a much better choice for a 24v bank

I agree with the battery voltage of 6 volt.

As for the diagram showing how to hook up your batteries. I would go with the "Method 2" wiring shown in the link that FloridaSun provided.

yes, but then I forgot about that lil word he said, 'free'. hahaha, does make a difference and only hope he's getting decent deep cycle batts with some use on them. Starting that way is fine as long as one is committed to upgrading with NEW batteries when the time comes.

very true.....I am just using these to get started to keep costs down....will buy some good 6v batteries for year 2.

Because I have 8 batteries and am only going to run 24v not 48v, I have to run them in 4 strings of 2 batteries. Does anyone have a diagram of how this would look? I get the 2 batteries in series, just not sure how to joing the 4 strings together properly.

The two batteries in "series" will have a wire running between the negative post of the first battery going to the positive post of the second battery.

Once you have done that for the 4 pairs of batteries you will then connect all of the positive posts on the first battery of each pair and all the negative posts of the second battery of each pair.

If you go back to that website and look at the "Method 2" diagram try to imagine each of those rectangles as a pair of batteries. What you see is the positive post on the left and the negative post on the right.

Gotcha, makes sense. Now how does the CC and inverter connect to the battery design from above?

Same as the diagram for 'Method 2' (+&- from opposite ends of the bank, NOT from the same battery)

The CC and the inverter should connect to the same pair of battery terminals. And that same pair should be as in Method 2. There is no reason to do it any other way.

However, if you have a lot of plain DC loads, you may find it easier to hook everything up and fuse it properly if you use a + and a - busbar instead of just cables direct to the batteries.
