Question:
Answer:
Don't know about the controller but I do know that if you can purchase Forklift batteries, they will last a very long time and 2-3 of them are enough to run a whole house.
Try the library on the controller or even contact your solar pannel manufacturer. If not in the US try a locar manufacturer like First Solar or Evergreen Solar. They have web sites.
