I am trying to create a system that will save energy from solarpanels to my battery and also sell the energy from battery to the grid. I have followed the instructions regarding installing the LG Resu battery to the Cerbo GX. But when doing so, the MPPT "disconnected" (both the battery and the MPPT was connected to the VE.Can bus on the Cerbo GX). I have read the ESS instructions and other blog post. But I cannot get it to work. My questions are:
- Where do i connect the RJ45 cable from MPPT in the Cerbo GX? The instruction for the LG Resu battery tells me that I have to connect it to the VE. Can bus and then the MPTT "is disconnected".
- Which settings do I have to change to make it work?
Here is a picture of the current status of the installation.
