March 22, 20215 yr Good day, please, give me an advice. I have a new MPP Solar PIP5048GK inverter and a new Pylontech US2000C battery. I made a cable for the communication between the inverter and the battery. Communication is functional, but an error 69 is displayed on inverter while the battery is being charged and the inverter stoped charging procces. How to fix this error? Thank you
