I tried to design a simple ESS system for a client that already had a solar system installed, and wanted to add batteries to save excess energy that goes into grid into battery for later use and vice versa.
I installed the system according to manual, updated all firmwares into latest, loaded up ESS assistant, sent settings into Multiplus-II and nothing... ESS doesn't even show color control...
Am i doing anything wrong or ESS just not working on latest firmware?
CCGX Firmware: v1.74
Multiplus-II VE.BUS Version: 2629476
System looks like the follwing:
Multiplus-II goes into "passthru" mode and never leaves it unless i disconnect Grid AC Input which then makes it to into Inverting.
I followed the manual Q4 that meantions passthru mode and possible causes, but nothing works...
I need urgent help with this, otherwise i will have to remove all Victron equipment from client and return it since it doesnt work...
