3.2.2 DRM (“AU”/“NZ”)
The inverter provides a terminal block for connecting to a demand response enabling device
(DRED). The DRED asserts demand response modes (DRMs). The inverter detects and ini-
tiates a response to all supported demand response commands within 2s.
The following table lists the DRMs supported by the inverter.
table 3-1 Demand Response Modes (DRMs)
Mode
Explanation
DRM0 The inverter is in the state of “Turn off”.
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 feed-in power to the grid is 0.
DRM6
The feed-in power to the grid is no more than 50 % of the rated power.
DRM7
The feed-in power to the grid is no more than 75 % of the rated power.
DRM8
The feed-in 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
3.2.3 Regular Operational Voltage Range
The inverters can operate within the allowable voltage range for at least the specified obser-
vation time. The setting of the conditions depends on whether the connection is due to a nor-
mal operational start-up or an automatic reconnection after disconnection from grid.
When the voltage level is out of the operational and protection levels, the inverter will discon-
nect within the specified time from the grid. If a disturbance lasts longer than the required
protection time, the inverter can reconnect to the grid once the voltage level goes back to
normal levels after the disturbance.
