DRED or RCR
Optionnal function.
• DRED (Demand Response Enabling
Device): the inverter satisfies the Australian
DERD certification and offers DRED signal
controlling ports.
• RCR (Ripple Control Receiver): In Germany
and some other European regions, grid
companies use Ripple Control Receiver
to convert grid dispatching signals into dry
contact mode for transferring. And the power
station receives grid dispatching signals
through dry contact communication mode.
