If only the circuit breaker is disconnected, the cable connection terminals in the AC/DC
cabinet of the energy storage inverter are still live!
Before opening the cabinet door and starting the formal maintenance work, it is necessary
to disconnect not only the circuit breaker, but also the front and back stage circuit breakers
of the energy storage inverter.
After the energy storage inverter is out of operation, please wait at least 15 minutes before
operating it.

Inspection
Observe whether the appearance of energy storage
inverter is damaged, deformed or rusted.
Listen to the abnormal sound of the energy storage
inverter.
LCD was used to observe the running parameters.
Use thermal imager and other detection systems to detect
the heating status.
Check whether the ventilation, ambient temperature,
humidity and dust around the inverter meet the
requirements.

Duct cleaning
Check duct dust.
Listen to if there is any abnormal vibration when the fan is
running.
Use compressed air and turn on the fan for cleaning.
Clean or replace the air filter

Due to the capacitance of DC bus, it will take at least 15 minutes to wait until the energy
storage inverter is completely cut off. Before removing the dust, please use the multimeter
measurement to confirm that there is no electricity in the machine, so as to avoid electric
