8. System Maintenance
After the system is powered off, there is still residual power and heat in the enclosure,
which may cause electric shock or burns. Therefore, in the systemTo operate the
accumulator 5 minutes after the power is off, protective gloves should be worn. Only when
all lights of the accumulator are off
Only then can the energy storage be maintained.
System power-off operation steps:
Step 1 Turn off the circuit breaker switch on the inverter with the battery pack input.
Step 2 Turn off the power button switch on all battery packs to ensure that all LEDs are
successfully turned off and all LEDs are off.
Observe whether the appearance of energy storage is
damaged or deformed. Listen to whether there is any
abnormal sound during the operation of theenergy
storage.
When the accumulator is running, check whether the
energy storage battery indicator is correct.
First commissioning and
testing half a year after this
It is then done every six
months to a year.
Check for disconnected or loose cable connections.
Check the cable for any damage,especially if there are
cuts in the sheath where the cable is in contact with the
metal surface.
Check that unused DC input terminals,energy storage
terminals, COM ports,and cable covers are locked.
Check that the grounding cable is reliably grounded.
