first off I suggest you get and use the one of the home power usage (analysis) work sheets from one of the dealer web sites. work this up and see what you are currently using then obviously pare it down. once you've done this you can get down to figuring just what you need. an awful lot people use the T-105 golf cart batteries. fair to good battery but to get the most out of them you need to treat them rite. I've heard of people get
6-7 years out of them. 5 years is more practical. these are the cheaper end and believe me you can spend lots more for batteries. mostly depends on what you want to spend or have to spend. what ever you do don't cut corners . it's going to take a small fortune to set yourself up.
