Maintenance
Inverters generally do not need any daily or routine maintenance. Heat sink
should not be blocked by dust, dirt or any other items. Before the cleaning, make
sure that the DC SWITCH is turned OFF and the circuit breaker between inverter
and electrical grid is turned OFF. Wait at least for 5 minutes before the Cleaning.
Inverter cleaning
Please clean the inverter with an air blower, a dry & soft cloth or a soft bristle
brush. Do NOT clean the inverter with water, corrosive chemicals, detergent, etc.
Heat sink cleaning
For the long-term proper operation of inverters, ensure there is enough space
around the heat sink for ventilation, check the heat sink for blockage (dust, snow,
etc.) and clean them if they exist. Please clean the heat sink with an air blower, a
dry & soft cloth or a soft bristle brush. Do NOT clean the heat sink with water,
corrosive chemicals, detergent, etc.
