The black-start function is only used in the off-grid environment and there is no
other power supply.
Note: If the battery is powered ON in black-start mode, the BAT port still has
high voltage and there is a risk of electric shock, even when there is no BMS
connection!
After the black-start mode starts, if the BMS communication can not be built
within 3 minutes, the black start will stop immediately.

6.1 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 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 its 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 properly
connected.
BMS_Internal_Err
1. DIP switch at the
wrong position;
2. The communication
