Step 2 For details about how to install battery recharge cables, see 8 Electrical
Connection.
Step 3 After the installation, refer to 8.9 Verifying the Installation to verify the

Battery Power-On and Commissioning
● Ensure that the charge process is supervised to prevent any abnormality.
● If a battery experiences an abnormality such as bulging or smoking, stop
charging immediately and dispose of it.
● Ensure that only trained professionals perform recharge operations.
● When the battery SOC is 0%, the product cannot be activated by pressing and
holding the power button. It can be started only after the solar power and AC
power are connected.
● It is recommended that a battery be charged to 50% SOC during recharge.
Long-term storage will cause capacity loss. After lithium batteries are stored at
the recommended storage temperature for 12 months, the irreversible capacity
loss is 3% to 10%.
Prerequisites
Power cables and signal cables are connected correctly.
Procedure
Step 1 Turn on the corresponding switch based on the scenario.
● 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.
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
o 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.

After battery modules are powered
o, static power consumption and self-
discharge loss may occur in them. Therefore, charge battery modules in a timely
