Unfortunately, the only way I could understand how to wire our batteries together was to draw a picture. Open Office<\/a> has a nice drawing program. Despite its niceness, my drawing is not attractive. I think though that it’s accurate and it’s nice to have as documentation.<\/p>\n

On a side note: Our blog is surprisingly nice for documentation. The other day I had to look up the pay load for the truck (hauling bags of cement) and it couldn’t have been easier.<\/p>\n

This is the physical layout as well<\/p><\/div>\n

The idea here is to create one giant 48 volt battery from a bunch (24) of 12 volt batteries.<\/p>\n

The process is to wire the batteries together both serially and in parallel. Groups of four batteries are wired together in series to get up to 48 volts. (In the picture, this is the little wires that go from positive to negative.) The blocks of 48 volts are wired together in parallel to create the giant battery. (In the picture, the red and black wires are in parallel.)<\/p>\n

Not according to plan, but electrically correct<\/p><\/div>\n

Yes, as Karen pointed out, not according to plan. I confess that when I bought all the solar equipment I didn’t understand exactly how it all went together. I can’t imagine what I was thinking. I didn’t have the right cables to follow my plan. I was going to order the right cables when I realized I could use what I had. Instead of linking each block together with the one above it, I link it with the one above and across. It’s the same electrically, but a little funky.<\/p>\n

This is an addendum to my original post. The battery wiring went through a little reworking. This is the final physical layout. I wouldn’t have added the horizontal wiring; however, since I had them I used them to insure the lowest possible resistance.<\/p>\n
