keywords: Communication connection between battery and hybrid inverter.
NOTE:
SHRT inverter series is compatible with SBRxxx .
SHT inverter series is compatible with SBRxxx and SBHxxx.
If the BMS communication to the hybrid inverter is abnormal, the Error Code 714 will be shown.
BATTERIES
SBR communication ports:
SBH communication ports:
HYBRID INVERTERS
SHxxRT BMS/CAN communication ports
SHxxRS BMS/CAN communication ports
SHxxT BMS/CAN communication ports:
The SHxxT series can be used with the SBRxxx as well as the SBHxxx series. Thus, two possible methodologies for Battery communication are given:
Method One: RS485 communication cable:
Method Two: RJ45 communication cable:
Communication connection:
The first two pins of the RS485 cable on the battery side are connected to the CAN H and CAN L of the inverter.
