Wiring Batteries for Solar

[@benkanobe7500]

Where did they get those cool battery connection grouments? I already have batteries for my pump (RPS) and would like to purchase them (preferably from the same folks they purchase from).

When connecting your positive and negative leads from battery to the charge controller, you should mount at opposite corners of your battery bank. This allows for even 'draw' and charge levels for each battery. Otherwise, you are relying on the first two batteries in your bank more than the entire bank.

H&H is absolutely correct. the diagram presented will kill all the batteries down the string over about a year in some studies i did in college. to prevent this, spend the money and make every connection to every battery in parallel exactly the same length. spend the money, or don't waste your money on batteries this is very common and does not last when done as a long string. Be advised also, that you will have to add panels to fill the tank as it were on those batteries. there is internal loss of current and that has to be replaced as well as usage. talk to a solar tech such as myself if you don't understand.

@dysfunctional_vet can you elaborate on spend the money to make sure all connections same length? Are those connectors he's using not good, thanks

I have a 60 foot well with a 240 volt 3/4 horse pump...how would I turn it into a solar off grid one?

[@jonathansilverman6683]

Good overview but could use a segment on connecting to the charge controller. When I did mine I got a big spark and wasn’t sure that was normal. RPS support helped me out as always but in a video like this it would be a valuable addition.

That's actually normal. It comes from the initial surge of power from the battery when connecting. You can prevent that by using a resistor or a lead pencil touching between the positive terminal and positive cable.
