12.3. Daily Maintenance
Usually, the inverter does not need regular maintenance and calibration. Due to natural heat
dissipation, the radiator must not be covered by dust and other dirt.
In order to ensure good ventilation of the inverter, it is necessary to check the radiator and
make sure that it is unobstructed.
If necessary, clean the inlet and outlet of the inverter with a soft brush. Do not use water,
corrosive chemicals or strong detergents to clean the inverter.

Before removing the fault, it is necessary to ensure that the circuit
breaker of DC or AC circuit is disconnected, and professional
personnel are contacted to deal with it. Other people are not allowed
to close the circuit breaker without authorization.
There is no repairable part in the inverter. If there is any problem, it
must be maintained by professionals. Even if the inverter has been
disconnected from PV and battery and power grid, it may still have
dangerous voltage. Before starting work related to electronic system
in the cabinet, the voltage of DC bus should be measured first. This
voltage must be below 48V.
