System integration
The inverter also can be equipped with advanced accessory board (UNO-
DM-COM KIT or UNO-DM-PLUS-COM Ethernet KIT) adding either an
RS-485 serial interface or the Ethernet communication interface enabling
the inverter to be used in one of the following operating mode:
- Dyamic feed-in control / Load Management (meter required):
In combination with the supported meter (connected to RS485 commu-
nication port) the inverter automatically adapt the output power in order
to get self-consumption to be maximise or avoiding to feed power to the
grid according to the system settings.
In addition, the advanced accessory board (UNO-DM-COM KIT or UNO-
DM-PLUS-COM Ethernet KIT) is equipped with a congurable switching
relay which can be used for manage external loads with custumizable
activation power and temporal thresholds (basic load management cap-
ability).
- Modbus Sunspec certied interface:
Thanks to the Modbus RTU/TCP communication protocol (Sunspec
compliant), the inverter can be easily integrated with third party monit-
oring and control system by using the accessory board (UNO-DM-COM
KIT or UNO-DM-PLUS-COM Ethernet KIT).
Please contact the ABB tecnichal support or get access to Sunspec alliance website for getting
the Modbus register map supported by the inverter.
- Congurable relay:
The inverter also can be equipped with advanced accessory board (UNO-
DM-COM KIT or UNO-DM-PLUS-COM Ethernet KIT) that provides a
congurable switching relay, which can be used in different operating
congurations that can be set in the dedicated menu.
A typical example of application is the activation of the relay in the event
of an alarm.
