Cooling fan working code:
Cooling fan of inverter is through detecting output power and over temperature situation to
work.
When start to turn on the inverter and output power is under 300W, the cooling fan does
not start running. It complies with saving energy sources requirement. Until, output power
is up to 300W, the cooling fan will start to work in order to drop the inner temperature.
If the ventilation opening is obstructed, the inverter will enter over temperature protection
mode (OTP). The cooling fan will continue working to drop the inner temperature. When
the temperature comes down to normal situation, the inverter will turn on automatically.
3 Maintenance:
Very little maintenance is required to keep your inverter operating properly.
You should clean the exterior of the unit periodically with a dry cloth to prevent accumulation of
dust and dirt. At the same time, tighten the Screws on the DC input terminals.
