To implementation of power management, the digital input interface receives the
specifications of the network operator via a ripple control receiver.
• Australia and New Zealand:
The inverter support the demand response mode (DRMs).
DRM 0 - Operate the disconnection device.
DRM 5 - Do not generate power.
DRM 6 - Do not generate at more than 50% of rated power.
DRM 7 - Do not generate at more than 75% of rated power.
And sink reactive power.
DRM 8 - Increase power generation.
(subject to constraints from other active DRMs)
• Customer : User defined.
The inverter can detect the state of the relay of the ripple control receiver.
The information which relay shall be controlled parameter by the network operator.
