SP PRO ABB UNO Managed AC Coupling
Introduction
The SP PRO Managed AC Coupling provides a method of linking the ABB UNO Selectronic
Certified (SCERT) inverters to the SP PRO via the AC Load supply so that regardless of whether
the grid or a generator is connected, the SP PRO can manage and control the ABB UNO string
inverters.
Each SP PRO can manage a maximum of five ABB UNO inverters by commanding each inverter
to output the right amount of power that is needed simultaneously to supply the load, export
any excess and maintain the battery bank at any particular point in time. This is done via a
communications link which also serves to retrieve all the operational data for display and
logging by the SP PRO.
Note: This document needs to be read in conjunction with the SP PRO Instruction Manual and
any relevant ABB UNO Instruction Manuals.
