Details on ABB’s new residential inverter series now available in the U.S.

ABB UNO-DM family

The new UNO-DM-PLUS-US series from ABB is now available for immediate shipment in the U.S. Available in five power ratings, from 3.3 to 6.0 kW, these solar inverters have a compact design that delivers high performance with excellent power density enabling maximum energy production. They are designed with digital intelligence and technical sophistication that optimizes the performance of residential PV installations.

Code compliance is not a problem with this family. 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 dual channel connections and installs to the panel in a snap, literally.

“The UNO-DM-PLUS’s new design wraps ABB’s quality and engineering into a lightweight and compact package; meanwhile, it embraces the digital advances and code requirements the industry requires,” said Mario Thomas, product manager for string inverters at ABB’s Solar business in the U.S.

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 configuration settings and Aurora Manager, which facilitates OTA firmware updates (remote software updates). Further efficiencies gained, with installation times greatly reduced due to an easy commissioning wizard, which simplifies the configuration process resulting in lower installation time and reduced costs.
