Battery Abnormal
1. In case of abnormal battery voltage, check whether
the battery power cable connection is abnormal (re-
verse connection, loose, etc.). If so, connect the bat-
tery power cable correctly.
2. Check whether the battery real-time voltage is ab-
normal if the battery power cable is correctly con-
nected. If so, contact the battery manufacturer. If not,
contact SUNGROW.
3. In case of abnormal battery temperature, take
measures to change the ambient temperature, such
as improving heat dissipation conditions.
4. If the fault persists, contact battery manufacturer.
