Hello, I am Jewel Hasan acting head of implementation from Rahimafrooz Renewable Energy Limited in Bangladesh. I have installed numerous Victron products across Bangladesh over the past 6 years. Recently, we installed a BYD battery with a Victron inverter and charge controller, but I am encountering issues with system commissioning. The BMU of the BYD Battery is indicating a communication failure with the inverter, and the BYD battery is not receiving a charge from either the grid or the solar PV system. I am seeking your assistance in resolving this issue. Could you please provide guidance on how to charge the BYD battery using either the grid or the solar PV system?
The Victron products we have installed are as follows:
# Charge Controller: Blue Solar MPPT150/85 - 2 units
# Inverter: Quattro 48/8000/110-100/100 - 3 units
# As well as - CCGX and Shunt are also available.
Thanks
