1. Generally, the fault will disappear by itself within 20
min.
2. In the event of continual and frequent occurrence of
this fault, please switch off the battery system, and con-
tact the installer or manufacturer to check whether the in-
verter is damaged.
3. Please contact the installer or the manufacturer if the
issue persists for a long time. Switch off the battery sys-
tem immediately if the SOC drops below 3% to avoid
damage caused by battery over-discharge.

1. Check whether there is a heat source near the battery
system, and measure the ambient temperature. The op-
erating temperature range of the battery system is 0 to
55℃ for charging, and -20 to 55℃ for discharging.
Please check whether the ambient temperature or the
battery temperature goes beyond this range. In case the
battery is placed near a heat source or in an unventilated
environment, or the ambient temperature is too high,
please improve the installation environment for the bat-
tery system.
2. Please contact the installer or the manufacturer if the
issue persists for a long time. Switch off the battery sys-
tem immediately if the SOC drops below 3% to avoid
damage caused by battery over-discharge.
