High altitude solar plant, Italy

ABB supplied the solar inverters for a plant at 3,452 meters on Mont Blanc’s Pointe Helbronner, to support the energy needs of a new cable car station.

A 13.3 kWp solar panel plant at the Pontal d’Entrèves’ base station covers an area of 160 square metres and a 12.9 kWp plant at Pointe Helbronner covers an area of 120 square meters.

The challenging environment of the plant required a solution that could withstand the extreme weather conditions and the rarefied atmosphere of such a high altitude.

The solar panel plant generators are connected to solar inverters supplied by ABB. Two ABB string inverter models provided the optimum solution.


The presence of two solar panel orientations led to this choice. It has (along with all UNO inverters with a power rating over 3kW) a double input. This allows separate management of two generators with different working conditions using a single inverter.


This inverter is part of the UNO family of single-phase inverters that represent the most efficient solution for the majority of rooftop installations. UNO family inverters are also ideally suited to resist extreme environmental conditions.
