Black-start configuration
The black-start function is only used in the off-grid environment and there is no
other power supply.
Note: if the battery is started in black-start mode, although there is no BMS
communication, the port still has high voltage and there is a risk of electric
shock!
After the black-start mode is started, if the BMS communication has still not been
built within 3 minutes , the black start fails.

Note!
When powering on the BMS, the system will start self-testing. If the
buzzer bips, it means DIP configuration fault or communication failure
occurs. If the buzzer bips, please check if the number of battery
modules is corresponding to the DIP configuration, and also check if
the RS485 communication calbes are correctly connected. After these
two situation checked OK, press the POWER button to power on, and
press the POWER button again 10s later. In addition: The buzzer will only
alarm on the corresponding fault during the power-on self-test. After
the self-test is completed, it won't bip again even if the same fault
occurs.
5.2 Commissioning
Verify the model number of each battery module to make sure that they are all
the same model.
If all the battery modules are installed, follow these steps to put it in operation.
1. Configure the DIP (Ⅳ) to corresponding number accroding to the number of
battery module(s) that has(have) been installed;
2. Remove the cover board of BMS;

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 with 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 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
