1. Connect the battery power cables between Inverter and BMS. Please pay
attention to connect the cables (+,-) to the correct BAT port on both the Inverter
and BMS.
2. Connect the negative cable (-) (B)to the port on the right and the positive
cable (+) (A) to the one on the left shown as in the figure.
4.5.5 Connecting Battery Power Cables
This step is to connect battery power cables between Inverter and T-BAT system.
The length of the cables are 2 meters, so you can appropriately cut the cable
accroding to the actual installation environment. Please note, each cable has only
one terminal block ready when leaving the factory, and you need to connect the
other end of the cable by yourself.

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 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.

NOTE!
When powering on the BMS, the system will start self-test. If the
buzzer bips, it means DIP configuration fault or communication failure
occurs. In this case, please press the POWER button to turn it OFF, then
check if the number of battery
modules is corresponding to the DIP configuration, and also check if
the RS485 communication cables are correctly connected. After
checking all these, press the POWER button to power it back on.
In addition: The buzzer will only alarm on the corresponding fault
during the power-on self-test. When the self-test is completed, it won't
bip again even if the same fault occurs.
5.2 Commissioning

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
