Delta 100kW PCS - Auxiliary Power Interface Connector; Demand Response Management; Black Start

Wiring Instructions
Installation Manual 49
Auxiliary Power Interface Connector (CNJ5)
CNJ5 is located on J board called Interface board, shown in the following figure. It is used for
alternative auxiliary power input with 24Vdc 0.5A. Connect two 1.32 ~ 0.326 mm
2
wires to the 2-pins
connector as the pin assignment table below. Customer can run PCS in black start mode via this
terminal.
Black Start
1. After the auxiliary power is connected, the communication part of PCS starts to work.
2. Make sure you connect the communication cable between the BMS and the PCS correctly and
the PCS battery manufacturer type is set correctly. The default setting is LGC battery in the
Modbus setting.
3. Turn on the auxiliary power of the BMS.
4. The BMS establishes a communication connection with the PCS, and the batter outputs the HV
DC.
5. The DC input of the PCS comes from the battery. Enters the island operation mode, starts the
PCS, establishes the microgrid, and completes the black start.
Demand Response Management (RJ45)
Demand Response Management
The inverter provides a RJ45 port to support the connection to a demand response enabling device
(DRED). The support is required as the DRED asserts demand response modes (DRMs). When the
inverter detects a demand response command, it initiates a response. The following table lists the
DRMs supported by the inverter.

Note:
The mandatory respond mode is DRM0 (standby), while support for the remaining listed
modes is option and may not be applicable for all models.
Table 12: Demand Response Modes (DRMs)
Mode Description
DRM0 The inverter is in standby.
DRM1 Power consumption from the grid is 0.
DRM2 Power consumption from the grid is no more than 50% of the rated power.
DRM3
Power consumption from the grid is no more than 75% of the rated power, while source
reactive power enabled.
DRM4 Increased power consumption, but subject to the constraints from other active DRMs.
DRM5 Do not generate power
DRM6 The export power to the grid is no more than 50% of the rated power.
