6. If the problem persists, check whether there is a heat source near the battery and whether
the ambient temperature goes higher than 55°C. Switch off the battery in the event of the
temperature exceeding 55° C, and restart and charge it when the temperature falls below
40°C.
7. Contact the installer or manufacturer if the problem can still not be resolved. Switch off the
battery immediately once the SOC drops below 3%.
9.2.2 Battery Not Discharging
1. Please wait 5-10 minutes for data refresh of iSolarCloud App.
2. If the problem persists, try discharging the battery by enabling force mode. If the battery
can discharge now, please contact the hybrid inverter installer or manufacturer.
3. Check if the current battery SOC is the same as the set SOC lower limit of the hybrid in-
verter. Once the battery SOC reaches or falls below the SOC lower limit, the battery will not
discharge (please set the value to 5-50 as needed).
4. If the problem is still not resolved, please check the system for any faults and take coun-
termeasures according to the fault code.
5. Check whether there is a heat source near the battery and whether the ambient tempera-
ture goes higher than 55°C. Switch off the battery in the case of the temperature exceeding
55°C, and restart and discharge it when the temperature falls below 40°C.
6. Contact the installer or manufacturer if the problem can still not be resolved. Switch off the
battery immediately once the SOC drops below 3%.
9.2.3 SOC Jump
1. Occasional occurrence of SOC jump is considered to be a normal phenomenon, which
does not affect the normal operation of the system.
2. In case the SOC jump issue occurs frequently, please contact the installer or
manufacturer.
9.2.4 Battery Upgrade
1. Please contact the installer or manufacturer for iSolarCloud upgrade, if needed.
2. If the iSolarCloud is updated, please upgrade the software of the hybrid inverter, the com-
munication module, and the battery at the same time. Otherwise, there may be problems
arising from the mismatch of software versions.
3. Please contact the installer or manufacturer immediately in case of anything abnormal
during or after the upgrade.
