serve and ensure that the agreed reactive power can be delivered from any active power operating point. The graphic
shows the appropriate P-Q operating range with a required example active power of 48% of the maximum apparent
power of the plant or 43% of the maximum active power of the plant.

The power reduction parameters can be adjusted in SunSpec model DID123. During this process, you should also check
whether internal and/or external power reduction is active.

If the ramp time "WMaxLimPct_RvrtTms" in the SunSpec model is specified as 0 s, then the internal output gradient is
used. Otherwise, the set value will be used.
Irrespective of the communication protocol used, the settling time "WMaxLim_Ena" is used in order to transfer the new
power value. Otherwise, the internally configured value will be used.
The additional ramp time "WMaxLimPct_RmpTms" specifies the jump time from a power value to the new power value.
