User Manual (MAP05A1, MAB05B1)
Prerequisites
Power cables and signal cables are connected correctly.
Procedure
Step 1 Turn on the corresponding switch based on the scenario.
●
●
Step 2 Turn the AC input switch to ON.
Step 3 Observe the annular strip light. If all green lights are steady on, battery charging is
complete.
Step 4 After the charge is complete, turn off the upstream AC input circuit breaker of the
iSitePower-M system and then the DC SWITCH. Hold down the manual ON/OFF
switch for 5s to shut down the battery module. If other batteries need to be
charged, repeat the preceding steps.

10.5 Storage with Low SOC
After battery modules are powered off, static power consumption and self-
discharge loss may occur in them. Therefore, charge battery modules in a timely
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:
●
●
●
●
●
Regardless of scenarios, the battery modules must be charged within the longest
interval corresponding to the SOC when the battery modules are powered off. If
the battery modules are not charged within the specified interval, the battery
modules may be damaged due to overdischarge.
Power-Off SOC Before Storage
SOC>5%
0≤SOC<5%

If there is PV input, turn on the DC SWITCH.
If there is no PV input, hold down the manual ON/OFF switch for 5s.
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 configurations in the
system.
The battery modules cannot be charged due to no PV input and long-term
mains failure.
