System integration
The inverter also can be equipped with advanced accessory board
(UNO-DM-COM KIT or UNO-DM-PLUS-COM Ethernet KIT) adding ei-
ther 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 configurable switching
relay which can be used for manage external loads with custumizable
activation power and temporal thresholds (basic load management ca-
pability).
- Modbus Sunspec certified interface:
Thanks to the Modbus RTU/TCP communication protocol (Sunspec
compliant), the inverter can be easily integrated with third party monitor-
ing and control system by using the accessory board (UNO-DM-COM
KIT or UNO-DM-PLUS-COM Ethernet KIT).
The Modbus RTU/TCP register map is the same for all the communication interfaces (Ether-
net, RS-485 and Wireless communication) of the inverter.
Please refer to ABB solar official website or get access to Sunspec alliance website for getting
the Modbus register map supported by the inverter.
- Configurable relay:
The inverter also can be equipped with advanced accessory board
(UNO-DM-COM KIT or UNO-DM-PLUS-COM Ethernet KIT) that pro-
vides a configurable switching relay, which can be used in different oper-
ating configurations 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.
