Hi, I'm running 2 x 5kVA Multis (one GX) in split-phase mode, all working fine until I enable ESS.
As soon as I add ESS (to both Multi's) the system crashes IE Low Battery Errors, (Error code: #67 - No BMS) and one of the Pylontech's seems to go offline (no power LED).
If I revert to no Assistants all works fine. One observation is the battery capacity reports 50% of the total during charge & discharge. I have copied identical ESS setups to both Multis and set 2x 200Ah on each. I've spoken to many experienced installed and tried & applied all their suggestions.
Any Ideas
