2.4 Ambient temperature
The inverter can be operated in an ambient temperature from -22 °F to 140 °F (-30°C to
+60°C). The following diagram illustrates how the output power of the solar inverter is reduced
automatically in accordance with ambient temperature.
The device should be installed in a well-ventilated, cool and dry location.
Due to tolerrance of temperature sensor and efficiency difference under different PV voltage, this
derating curve may be a litter different from actual behaviors of unit.
