ATMOCE – MI-450 Microinverter

With 450W of power and a 97.4% efficiency, the ATMOCE MI-450 microinverter extracts maximum energy from your solar panels. Its intelligent technology automatically adapts to variations in sunlight to maintain optimal production throughout the day. Tested for over one million hours and backed by a 25-year warranty, the MI-450 is built to last.

Its waterproof casing withstands extreme weather conditions , from -40°C to +65°C, rain, snow, or wind. Lightweight at only 1.3 kg and compact, it attaches directly behind your panel in minutes thanks to its plug-and-play connectors. No complex wiring is required: communication is handled directly through the existing electrical network, greatly simplifying installation.

You can monitor the output of each panel from your smartphone or computer, allowing you to immediately detect any problems and maximize your return on investment. Low DC voltage makes installation safer for both installers and occupants, while European certifications and integrated surge protection ensure complete peace of mind.

The MI-450 is compatible with all standard solar panels on the market and is ideal for single-family homes, commercial buildings, and industrial facilities. Its flexibility allows for customized configurations, even on complex roofs with multiple orientations. The main advantage of the micro-inverter system is that if one panel is shaded or malfunctions, the others continue to produce at full power, whereas with a central inverter, the entire system loses efficiency.

Certified according to European standards EN IEC 62109-1/-2 for electrical safety and EN IEC 61000-6 for electromagnetic compatibility, the MI-450 meets the strict requirements of national and European regulations (VDE 0124, VDE 4105, UTE 0126, EN 50549, EN 50530).
