8.5 Power Derating
In order to ensure inverter operation under safe conditions both from the temperature
and electrical point of view, the unit automatically decreases power input to the grid.
Power derating can occur in two cases:
Power reduction due to environmental conditions
Power reduction and temperature at which it occurs depend on many operating
parameters other than ambient temperature, such as input voltage, grid voltage, and
power available from the photovoltaic panels. AURORA can thus decrease power
output during certain periods of the day according to these parameters.
In any case, AURORA ensures maximum power up to 122°F for PVI-4.6-I-OUTD, up
to 140°F for PVI-3.8-I-OUTD provided it is not directly exposed to the sun.
Power reduction due to input voltage
The graph shows automatic power output derating when input or output voltage is too
high or too low.
