Since the beginning of this year, all new energy generators in Austria must be designed so that they can be disconnected by the grid operator using ‘Dynamic Response Management (DRM)’.
I can find this information in the EP600 documentation, but not how DRM is implemented.
Where can I find additional information on how/where the cable must be connected, and which signals to which pins?
Hello, application scenario: The system can issue a signal to automatically start the diesel generator to provide backup power when needed.
Hello @BLUETTI ,
Just to make sure I understand correctly, the DRM port of the EP600 is implemented as an output? That means the EP600 controls another device (diesel generator)?
Or can I use the DRM port to deactivate/throttle the EP600?
If the DRM port cannot (!) be used to control the EP600, how am I supposed to implement the new guidelines in Germany and Austria, which stipulate that ALL new PV inverter and generators can be throttled by the grid operator via a DRM signal (60% rule in Germany, 0% in Austria)?
Without this option, the new systems will no longer be approved and will no longer be allowed to feed into the grid (only as a stand-alone solution).
In this case, the EP600 (and probably also the EP760, EP900, etc.) can only be used as a backup battery, but not as a PV inverter for feeding into the grid!
For further clarification, the network operator uses these DRM modes for control purposes:
Mode Requirement
DRM0 Operate the disconnection device
DRM1 Do not consume power
DRM2 Do not consume at more than 50% of rated power
DRM3 Do not consume at more than 75% of rated power and source reactive power if capable
DRM4 Increase power consumption
(subject to constraints from other active DRMs)
DRM5 Do not generate power
DRM6 Do not generate at more than 50% of rated power
DRM7 Do not generate at more than 75% of rated power and sink reactive power if capable
DRM8 Increase power generation
(subject to constraints from other active DRMs)
