Environment

Altitude

Less than 1000 meters, no derating required. For places with an altitude of more than 1000 meters, please reduce the rated voltage and rated output current by 1% for every 100 meters increase. When the altitude exceeds 3000 meters, it is necessary to consult the manufacturer for guidance.

Ambient temperature

-10 ℃ ~ +40 ℃, the ambient temperature exceeds 40 ℃, and derating is required. For every 1 ℃ increase in the ambient temperature, the derating rate is 1%. When the ambient temperature exceeds 50 ℃, consult the manufacturer for guidance. The ambient temperature is lower than -10 ℃, and additional auxiliary heating equipment is required.

Humidty

Less than 95% RH, no water condensation.

Storage

The storage temperature is -20 ℃ ~ +60 ℃. At the same time, due to the characteristics of the electrolytic capacitor, the storage time is more than half a year. The inverter needs to be powered on for 10-30 minutes every six months to charge the electrolytic capacitor.
