Power Factor Derating
When the power factor PF<1.0, the inverter will reduce the output power within a specified range.
The following figure shows the power factor derating curve.
5.5 External Demand Response
The inverter provides a terminal block(RJ45) for connecting to a demand response enabling
device (DRED). The DRED is demand response modes (DRMs). The Dred Demand Response
Model (DRMS) is applicable in Australia. The inverter detects and initiates a response to all
supported demand response commands within 2s.
The following table lists the DRMs supported by the inverter.
Mode Explanation
DRM0 The inverter is in the state of
“Disconnect Output”.
DRM1 The import power from the grid is 0.
DRM2 The import power from the grid is no more than 50% of the rated power.
DRM3 The import power from the grid is no more than 75% of the rated power.
DRM4 The import power from the grid is 100% of the rated power, but subject to the
constraints from other active DRMs.
DRM5 The export power to the grid is 0.
DRM6 The export power to the grid is no more than 50 % of the rated power.
DRM7 The export power to the grid is no more than 75 % of the rated power.
DRM8 The export power to the grid is 100 % of the rated power, but subject to the
constraints from other active DRMs.
The DRED may assert more than one DRM at a time. The following shows the priority order in
response to multiple DRMs.
Multiple Modes Priority Order
DRM1
…DRM4
DRM1 > DRM2 > DRM3 > DRM4
DRM5
…DRM8
DRM5 > DRM6 > DRM7 > DRM8
