I have two Hab 3 versions of the kilovaualts and a newer Hab 4 version all from alt-e. These are 7.5 kw LifePO batteries
These are connected to one another with communication cables-the 3s worked fine with each other-the 4 has never communicated with eth 3s.We are working thru an exchange now under warranty on a nother version 4 that will hopefully talk to the 3s. They do work as one if communication is turned off as they all land on a single buss bar before heading into the Sol-Ark.
Anyone elese have these batteries and are they talking to one another .?
