Delta H2.5 - Digital Input

Active/Reactive Power Control and LVRT (Optional)
36
6.8 Digital Input
To implementation of power management, the digital input interface receives
the specifications of the network operator via a ripple control receiver or a DRED.
H2.5/H3/H3A/H4A/H5A can access these command via DC1_100.
• 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.
And sink reactive power.
DRM 8 - Increase power generation.
(subject to constraints from other active DRMs)
