Fimer Inverters

Fimer Inverters


FIMER Group completed the acquisition of the ABB solar division in March 2020.   All ABB inverters are now manufactured under a trade license agreement with FIMER Group and some inverters may state this on inverter cover plates and literature.

Based in Italy, Fimer are one of the largest manufacturers of Grid Tie inverters worldwide.

Fimer’s UNO family of single-phase string inverters complements the typical number of rooftop solar panels, allowing homeowners to get the most efficient energy harvesting for the size of the property.

The high-speed MPPT offers real-time power tracking and improved energy harvesting.

Efficiency of up to 97%

The transformerless operation gives the highest efficiency of up to 97%. The wide input voltage range makes the inverter suitable for low power installations with reduced string size.

This rugged outdoor inverter has been designed as a completely sealed unit to withstand the harshest environmental conditions.




The UNO-DM-TL-PLUS-Q single-phase inverters, from 1.2 to 3.0 kW, are the optimal solution for residential installations.

All power ratings share the same housing and come with single Maximum Power Point Trackers.

The Plug and Play connectors, both on the DC and AC side, as well as the wireless communication, enable simple, fast, and safe installation.   The easy commissioning routine assists faster installation times and reduced costs.

The embedded logging capabilities and direct transferring of the data to the Internet (via Ethernet or WLAN) allow customers to enjoy the Aurora Vision® remote monitoring experience.

This tool allows customers to remotely monitor the performance of their solar system and assists with energy self-reliance and self-sufficiency.


  • Wireless access to the embedded Web User Interface
  • Easy commissioning capability
  • Future-proof with embedded connectivity for smart building and smart grid integration
  • Dynamic feed-in control (including zero injection)
  • Remote firmware upgrade for inverter and components




The UNO-DM-TL-PLUS-Q single-phase inverters, with power ratings from 3.3 to 5.0 kW, are also optimal solutions for residential installations.

All power ratings share the same size cabinet and feature dual Maximum Power Point Trackers.




The UNO-DM-6.0-TL-PLUS-Q single-phase inverter is an upgrade of the proven UNO family and is an optimal solution for larger residential installations.

The inverter allows high performance in a minimum space and has dual Maximum Power Point Trackers.
