It’s been a long time between drinks, but ABB’s new single-phase solar inverter – the UNO-DM-PLUS – will be available in Australia from mid-July.

Available in six power ratings from 1.2 to 5.0 kW, ABB says the UNO-DM-PLUS string inverter provides higher performance and all DM-PLUS models are the same compact size (553 x 418 x 175 mm). The new units, all of which weigh 15kg, offer a maximum efficiency of between 94.8% and 97.4%; depending on model.

UNO-DM-PLUS features plug-and-play connectors; so the cover doesn’t need to be removed. Combined with a commissioning wizard, these features lower installation time says the company, saving money.

An in-built user interface enables access to advanced inverter configuration settings, dynamic feed-in control and load manager; which can also be accessed through wireless communication.

Calling it “future-proof”, ABB says the UNO-DM-PLUS also features remote Over The Air (OTA) firmware upgrade functionality.

“.. the new design wraps ABB’s quality and engineering into a lightweight and compact package, which thanks to intelligent technological choices means we have created an inverter solution which is optimized for domestic solar installations,” said ABB’s Giovanni Frassineti earlier this month.

Manufactured in Italy, the UNO-DM-PLUS comes with a 10 year standard parts and labour warranty. More information on the UNO-DM-PLUS can be found here.

ABB’s Aruba Microgrid Project

In other recent news from ABB, the company announced last week it will provide an advanced microgrid solution to the main power utility serving the Dutch Caribbean island of Aruba.

With a population of approximately 103,000 and a popular tourist destination, Aruba sources its electricity through a mix of thermal, wind and solar PV generation.

ABB’s solution will enable WEB Aruba N.V. to integrate more renewable energy capacity, while maintaining reliability and efficiency of power supplies – and meeting increasing demand for electricity

“The embedded software, automation and control technologies will also facilitate 24 hour forecasts and enable a stronger, smarter and greener grid,” said Massimo Danieli, head of ABB’s Grid Automation business.

Aruba is looking to free itself from the clutches of fossil fuel based power generation entirely and has set an interim goal of sourcing half its annual average electricity requirements from renewables by 2020. Currently, nearly 40 percent of the island’s electricity is sourced from clean power technologies.

Aruba’s largest solar power installation is a 3.5MW facility at Reina Beatrix International Airport, which consists of 14.000 solar panels.

Last November, Tesla signed a Memorandum of Understanding with WEB to supply Aruba with energy storage systems.

  1. Jay-Ar Guanzon says


    Does this DM-Plus can operate without grid and battery?

    • Ronald Brakels says

      I’m afraid it’s an on-grid inverter only. Batteries cannot be connected directly to it, but they can still be added to the home using AC coupling. Inverters for off-grid use will generally need to be multimode inverters, also known as hybrid inverters.

  2. My Abb uno 3.3kw has message waiting sun after install. No power is generated. Waiting for Sunterra contact abb for a solution. Could you please help me for a reason? Thank you. Vu

    • Ronald Brakels says

      Hello Vu

      The message “waiting sun” sounds like the inverter isn’t receiving current from the solar panels. There may be a problem with the DC connections or it might just be a glitch with the inverter. Hopefully it is something Sunterra can fix easily and quickly.

  3. Thank you for your advice.
