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:
