Question is can I run on just 3 or 2?you cannot add to a bank
like water seeking its own level.
run on three, or pony up four 4 new
fact of battery world....... sorry
Koreano,
How old are the other Batteries? If they are over a year, one solution is to change the one bad battery for a second hand one about the same age as the others. Also you must charge it to the same state as the others. If they are fully charged so must the one you put in.
I have done this a number of times and have 12 Batteries. If you have more than one string of 4 batteries -ie 8 itis possible to change a one whole string with 4 new. I have also done this a number of times with no bad effects.
I am sure many posters will jump on this reply but I have been carrying out an experiment for the last 8 years and my Batteries are now -one bank 3 years old, one bank 2 years old and one mixed of old good ones and a same age replacement.
Do not put a new one in with the old ones but get a good second hand one about the same age, capacity and state of charge as the others. The same brand is also a good idea but it doesn't seem to make much difference.
A battery load tester should be used to identify the bad batteries and the good ones.
Hope that helps and look forward to the tirades in response.

Koreano,
The invertor wont run of 2 or 3 batteries so you have to get another. Get a one or two year old trojan red T105 - these are often available. Dont know where you are but "Facebook - Everything Cabarete " has some second hand batteries advertised.

WW - dont understand your post ?
Windeguy,
You can adjust what the new string gets by how you connect the main lines from the invertor . Twelve batteries - connect the main leads to the oldest string of batteries and the interconnection leads give you enough differential that you dont cook the new ones. All the batteries must show "Good" on the load test.

It is DEFENITLY "Conventional Wisdom" here that you should NEVER replace one battery in a "Bank".
However, I have NEVER seen a "Link" actually say that it's TRUE!!!!!

I WOULD LOVE TO SEE ONE!!!!!
