Appendix B
Digital Input
To implement power management, the digital input interface receives the specifications of the
network operator via a ripple control receiver.
• Germany : The active power limitation in the stages 0%, 30%, 60% and 100%
• Italy : Power output of Max 6KW for PV plant installation.
Remote shutdown
Narrow Frequency limits between 49.5 Hz to 50.5Hz.
• 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.
DRM 8 - Increase power generation.
• Customer : User defined.
Ripple control receiver
Figure B-1: Pin assignment at ripple control receiver
The inverter gives a voltage to the Output (6) and measure Digital Input (1 to 5). The inverter can
detect the status of the relay of the ripple control receiver. The information which relay shall
be controlled parameter by the network operator.
And sink reactive power.
(subject to constraints from other active DRMs)
