8.5Power Derating

To ensure inverter safe operation under any temperature and electrical condition, the unit will automatically derate the power to be delivered to the grid.

Power derating can occur on one of the two following occasions:

Power Derating due to Ambient Temperature

Under certain operating conditions, AURORA automatically regulates the power to ensure that the components are always run well-within their operating temperature limits. Several environmental factors can influence the operating temperature of the unit, such as ambient air temperature, airflow, exposure to sun radiation, input voltage and power, orientation of the heatsink fins, etc.

AURORA supplies the max output power for ambient temperatures ≤ 40°C, provided it is not exposed to sun radiation or other direct heat sources which may affect the internal thermal behavior.

Power Derating due to Input Voltage

The graph shows the automatic derating of delivered power when input voltage values are too high or too low.
