Ok so to answer some questions. When I said upgrade I guess I should have said replace, but what better time to get something better. The current group 24s are ac delcos multi pupose. From what I've found the are only about 55-60ah ea an at this point when I pull 60ah out of the bank it is about 50%. 1 is 3 years old and the other 2 are about 2 years...
I fulltime an do have access to shore power but try to avoid it if possible. I currently am using between 50 an 60 ah per day. I would like to have enough capacity to go a couple days of bad weather.
As for adding more batteries in the future, it would be in the next 6 months if needed. I am looking to add to the solar hopefully in the next month or so. I have to climb up an see if I have room for 2 more 140w's. If not it will be a 140w and an 100w.
This is what is currently up there.....
