Currently have 2 x 5.2kWh batteries, thinking of adding another.
Quite capable of doing the wiring myself, but I guess there is a proper way to connect in the additional battery (I already know about the DIP switch settings) - do you have to ensure that all three batteries are at the same state of charge, for example?
Also..............warranty?
There is a training course provided by GE for this, all free. I will find the link the repost it. I was looking at adding a second batt to my system but asking a mate who's a sparky to it. Tad cheaper than an official installer!
This can affect warranty agreements in place with your original installation company, as you are effectively opening up and wiring into existing workmanship that was signed off. We highly suggest before doing so contacting them and requesting their permission for this in writing.
Adam-Reynolds I can confirm EON do not agree to this. But doing it yourself or a friendly sparky to do it could save £800
