Hello,
I am hoping some Schneider Conext XW Pro experts can help me with a problem.
Short summary: I have an XW Pro connected to the grid, and it is primarily a battery charger. I have two other XW Pros supplying power from batteries. I have EG4-LL batteries and BMS communication is working.
The Charger XW Pro is charging at night and I cannot figure out why. Here is the nighttime battery chart:
It started charging at 12:19 am:
It stopped when the batteries were at 50% charge. This parameter I understand. The High SOC Cutout is set to 50%. It happened again at 2:47 am.
I think it is starting the charge because of two possible reasons: the SOC touches 45% or maybe the battery voltage drops to 52.4V.
These numbers are nowhere in the inverter settings.
I have seen some really good comments from Schneider experts. This has me baffled. What am I missing? Also, these are the Charge Controller settings.
The Charge Controller MPPT 100 600 seems to have no communication with the BMS. I am surprised there is no setting for Li-on batteries.
I appologise for the long post, but hopefully some wizard can scan my settings and point out any obvious errors.
