Hello,
I have a system consisting of 3 Multiplus, with 120kWh Batteries (JKBMS), it is controlled externally via Modbus.
Charging stops at 56.9V (16s), the external control will still push the Charge command (never goes to 0), but the Multiplus will start to discharge with 12kW after around 50min with 0 Load. This is very consistent and happens each time the battery is charged to 100%. It takes around 20 minutes to stop again, until then no external control is possible.
What settings might cause this? I assume it's some security feature related to voltage? Might it be caused by some force-discharge communicated by JKBMS?
Thanks for any tips
