manner and do not store them in low state of charge (SOC). Otherwise, the
battery modules may be damaged due to overdischarge and need to be replaced.
Storing battery modules with low SOC may occur in the following scenarios:
● DC SWITCH on the power control module is OFF.
● The battery module power cables or signal cables are not connected.
● The battery modules cannot be charged due to a system fault after discharge.
● The battery modules cannot be charged due to incorrect
congurations in the
system.
● The battery modules cannot be charged due to no PV input and long-term
mains failure.
Regardless of scenarios, the battery modules must be charged within the longest
interval corresponding to the SOC when the battery modules are powered
o. If
the battery modules are not charged within the specied interval, the battery
modules may be damaged due to overdischarge.
Power-O SOC Before Storage Maximum Charge Interval
SOC>5% 30 days
0≤SOC<5% 7 days
When the battery SOC decreases to 0%, ensure that the battery modules are charged
within seven days. Permanent battery faults caused by delayed charge due to customer
reasons are beyond the warranty scope.
