String inverters


The three-phase commercial inverter offers more flexibility and control to installers who have large installations with varying aspects or orientations.

The dual input section containing two independent Maximum Power Point Tracking (MPPT), allows optimal energy harvesting from two sub-arrays oriented in different directions.

The TRIO features a high speed and precise MPPT algorithm for real power tracking and improved energy harvesting.

NOTE: If installing a PV system using TRIO in North America, please verify that the selected PV module is listed for use in 1000Vdc systems in accordance with local electrical codes.
