DLS 300 / 450 / 600
Power Derating
In order to ensure thermal and electrical safety during the operation of the DLS system, the power drawn
from the grid by the system is automatically reduced.
The power derating can occur for adverse ambient conditions or inadequate input voltage values.
Although the power derating conditions may be caused both by adverse ambient conditions and inadequate
input voltage, the power derating will always be related to the lower value detected.
Power Derating Caused by Ambient Conditions
The power derating and the DLS system temperature detected when it occurs depend on the ambient tem-
perature and on many operating parameters. Example: input voltage, mains voltage and power available
from the PV array.
Therefore the DLS system can reduce its power during certain times of the day according to the value of
these parameters.
However, the DLS ensures the maximum output power even with high temperatures; see technical fea-
tures.
Power Derating Caused by Input Voltage
The DLS system reduces its output power if the input voltage from the PV array is too low and exceeds the
maximum input current for each input.
