ABB’s single-phase inverter family is smart, optimal, and code compliant for an efficient solution in residential solar installations. The new UNO-DM-PLUS-US series is now available in five power ratings, from 3.3 to 6.0kW. These solar inverters have a compact design, delivering high performance with excellent power density enabling maximum energy production. They are designed with digital intelligence and technical sophistication which optimizes the performance of residential PV installations. The UNO-DM-PLUS-US series is Rule 21 phase 2/UL1741-SA and is SunSpec Certified. The UNO-DM-PLUS-US series is compatible with ABB’s string-level Rapid Shutdown. The ABB RSD 2.0 unit is available in single and duel channel connections and quickly installs to the panel. This flexible inverter design comes with embedded connectivity and efficient communication SunSpec Protocol, which enables the UNO-DM-PLUS-US to be easily integrated within any current or future device for smart building automation, smart grid integration, and with third party monitoring and control systems. The UNO-DM-PLUS-US also comes with remote Over the Air (OTA) firmware upgrade for inverter and components. Once the inverter is installed, operators can turn to a smartphone to commission the unit via a simple, built-in web user interface. This enables them to gain access to features such as advanced inverter con-figuration settings and Aurora Manager, which facilitates OTA firmware updates (remote software up-dates).
