Hi, I have been struggling a lot to get my multiplus II feeding back into the grid. I have a Modbus controlled multiplus 2 via a Cerbo GX with Pylontech batteries. Everything I can control perfectly fine via Modbus. Only when I change the grid setpoint to a negative value nothing happens. When I change it to a positive value the multi start charging the batteries with the selected value.
I followed all steps in the manual for the Pylontech batteries setup in VE configure 3.
Multiphase regulation is set to individual phase
There is no pv coupled just the multi with the batteries and the grid
DVCC is forced on
Does anybody an idea why I can not feedback?
