Hi, i am Using a Pylontech Powercube - SC1000-100 + 14*H48050! I installed (my) latest Firmware on the BMS 5.7 Using HV Battery View 3.9.4 but i have different Firmware Versions on the H48050. Pylontech do not answer me - my companies where i bought the H48050 can or will not help me! Anybody can help me? Thanks Helge
