Good dag all. I have an growatt spf 5000es and 4.8kwh pylontech battery with 4 x 415w panels. Its connected to the grid also.
Problem i have currently is that the inverter doesnt connect to the inverter with the bms cable. The Li keeps on flashing and then the other problem is that the PV panels also doesnt show on the inverter.
Did test the pv array and pushes good. Until you plug the into the inverter then the volts are gone. Only pushing 200volts
Any help please....firmware problem? Programing problem? Please assist
