6peluqppy_66a93554057c8.pdf · page 12C07MOS overtemperature.Critical
MOSFET (power switch) temperature is over the protection limit.
1. The inner temperature is over the limitation. 2. Check whether the ambient temperature is too high.
Reduce ambient/inner temperature; allow the unit to cool. Verify ventilation and that ambient temperature is within the operating range.
6peluqppy_66a93554057c8.pdf · page 12C08MOS undertemperature.Critical
MOSFET (power switch) temperature is below the protection limit.
1. The internal temperature is lower than the limit range. 2. Check whether the ambient temperature is too low.
Raise ambient/inner temperature; verify ambient temperature is within the operating range.

6peluqppy_66a93554057c8.pdf · page 13C13Parallel failed.Critical
Battery pack failed to establish or maintain parallel operation with other packs.
Single unit may be incorrectly set to parallel system; or wiring between parallel-connected battery packs is incorrect/incomplete.
1. Please check if a single unit is installed to the parallel system. 2. if this error happens during parallel installation, please check wires connection. if they are connected correctly, please finish parallel installation first, and then restart the unit. 3. if the problem remains, please contact your installer.
6peluqppy_66a93554057c8.pdf · page 13C14Output loss.Critical
BMS detected loss of output from the battery pack (no power on the output side).
Circuit breaker may be open, or the fuse may be blown.
1. Please check whether the circuit breaker is closed. 2. Please check whether the fuse is normal. 3. Restart the unit. if the error persists, contact the repair center.
