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
connected.
BMS_Internal_Err
1. DIP switch at the
wrong position;
2. The communication
between battery
modules is interrupted
1. Move the DIP switch to
the correct position;
2. Check if the
communication cable
between battery modules is
correctly and well
connected.
