Battery Power-On and Commissioning
NO TICE
● 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 charge operations.
● When the lithium battery SOC is less than or equal to the value of End-of-
Discharge SOC for Lithium Batteries(%), the product cannot be activated by
holding down the manual ON/OFF switch. It can be started only after the PV
power and AC power are connected.
● It is recommended that a battery be charged to 50% SOC during charge. 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 switches based on the scenario.
● If there is PV input, hold down the manual ON/OFF switch for 5s, and turn on
the DC SWITCH.
● If there is no PV input, hold down the manual ON/OFF switch for 5s.
