To shut down the system, follow the steps described below:
1. Turn off the breaker between Inverter and battery pack;
2. Open the upper cover board;
3. Power off the BMS;
4. Turn off the system by moving the circuit breaker switch to the OFF position;

Status of battery pack
S1
S1 and S2 represent independent status indicators. The status of S1 and S2 have
the same meaning for battery pack in the following table.
Note: only when both S1 and S2 are flashing once every 5s in Green LED, it
means the battery system is active.
NOTE!
After powering off the BMS, the LED lights of S1 and S2 will keep
flashing in 20 minutes.
Light off
The Green LED is light on for 1s, and light off for 4s
The Orange LED is light on for 1s, and light off for 4s
The Green LED is light on for 0.3s, and light off for 0.3s

Troubleshooting
Check the indicators on the front to determine the state of the T-BAT system. A
warning state is triggered when a condition, such as voltage or temperature is
beyond the design limitations. The T-BAT system's BMS periodically reports its
operating state to the inverter.
When the T-BAT system 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:
BMS_External_Err
The communication
between BMS and
Inverter is interrupted
Check if the
communication cable
between BMS and Inverter
is correctly and well
connected.
BMS_Internal_Err
1. DIP switch at the
wrong position;
2. The communication
between battery packs
is interrupted
1. Move the DIP switch to
the correct position;
2. Check if the
communication cable
between battery packs is
correctly and well
connected.
