Wiring Batteries for Solar

Today, Mike walks you through the wiring process for our ultimate off-grid deep cycle batteries from Back40 Solar! The highest quality VLRA sealed batteries with operation lifetime up to 15 years and 1,350-1,550 cycles (50% DOD) before they lose only 40% of their capacity.
Compare that to standard flooded lead acid batteries and you will see you are getting 3-4 times the lifetime for about the same cost. Plus at 55ah and 12V, these pack a punch yet are easy to carry and handle.
Gone are the days of checking and filling batteries every few months and risks with battery acid spilling. Bar none, these are the highest quality and longest lifetime lead acid batteries on the market today!

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

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).

[@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.

[@wasabininja3494]

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.

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?
