3.4 Remote active power control (RS485 port)
In some countries, it might require that the generating plants should be equipped with a logic interface
(input port) in order to cease output active power or limit active power to a regulating level. This logic input
can be RS485 port, Ethernet port, etc. DTU-Pro provide RTU Modbus protocol over RS485 port for this
remote active power control. For more information, please refer to “Modbus implementation Technical
Note”.
3.5 DRM Port
DRM port is provided to support several demand response modes as below by connecting external control
device with a standard RJ-45 connector. For DTU-Pro, it can support DRM0/5/6/7/8 if used with Hoymiles
microinverters.
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)
