User Manual V1.0-2023-10-30
• The smart meter and CT have been preset parameters before delivered with the inverter. Do not
modify the relevant parameters.
• The BMS communication cable and meter communication cable are delivered with the inverter,
with default length of 3m and 10m respectively.
• Each inverter needs to be connected to one smart meter independently. Do not connect one
smart meter to multiple inverters. Contact the manufacturer or supplier to purchase additional
smart meter(s) if you need.
• Ensure that CT connects with the corresponding phase line: CT1 is connected to L1; CT2 is
connected to L2; and CT3 is connected to L3. And ensure that the CT is connected in the right
direction. Please refer to the smart meter user manual for detailed operations.
• Use the included BMS communication cable to realize communication between the inverter and
the battery. Otherwise, the communication may fail. If more communication cables are needed,
please prepare network cables and RJ connectors by yourself to make the cable. Only crimp
PIN4 and PIN5 of the connector when making the cable, otherwise the communication may fail.
