Electrical connection
There are 2 ways to connect the battery with the inverter. The details as follows.
Single unit is connected to the inverter, Please find the following diagram for details. 
Multiple units are connected to the inverter, Please find the following diagram for details. 
Troubleshooting
Check the indicators on the front to determine the state of the battery pack. a warning state is triggered when a condition, such as with voltage or current or temperature, is beyond design limitations. The battery pack’s BMS periodically reports its operating state to the inverter. when the battery pack falls outside prescribed limits, it enters a warning state. When a warning is reported, the inverter immediately stops operation. use the monitoring software on the inverter to identify what caused the warning. The possible warning messages are as follows:
- Battery Over Voltage
- Battery Under Voltage
- Battery Over Temperature
- Battery Under Temperature
- Battery Discharge Over Current
- Battery Charge Over Current
The abnormal state is cleared when the battery pack recovers normal operation.
