8.5 Power 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.
