Materials : Multiplus II 5KV + CCGX v2.90+ 4 Pylontech batteries.
Everything was working fine except some recent alarms rise on High voltage battery.
I took the opportunity to upgrade Mutliplus II from V459 to V497 using VRM. The ESS that was ok is now empty menu with No ESS assistant found.
I tried to use VE configure 3 to re-initialize the ESS assistant but no way, VE configure 3 does not see my CCGX and the Multiplus while VictronConnect is able to see the CCGX.
Please drive me to the right direction to re-engage the ESS mode on the CCGX, I am lost now.
