Hi all,
ESS-system details are: MP-II GX 3000, Pylontech US2000C and 2 MPPT
Wiring and setup according to pylontech_phantom.

But currently it is not connected to grid because we wait for approval of grid company.
Issue is that MP-II and Pylon BMS are showing constantly different voltages as shown in dashboard
49.78V (BMS) vs. 52.36V (MP):
Impact is that Multi doesn't allow the battery to be charged by MPPTs because it is sharing the wrong voltage with them, and 52.4V is the charge limit. For example 1 MPPT has:
But the battery does actually have only 49.78V
GX-system setup battery monitor is autoselected with Pylontech.
I could not find any hint why this is happening. Does someone had similar results and what could be done to get Multi to use BMS voltage ?
Thanks in advance for any help.
