Fronius Symo Advanced Three Phase Commercial String Inverter with Data Manager 2.0 Card

Fronius Symo Advanced Three Phase Commercial String Inverter with Data Manager 2.0

The Fronius Symo Advanced represents the next evolution in the SnapINverter portfolio, combining proven commercial performance with advanced safety features. Designed with power categories from 10 kW to 20 kW (with additional models up to 24 kW), this three-phase inverter is an ideal solution for commercial photovoltaic systems of all sizes.

A key highlight is the integration of Fronius Arc Guard technology, delivering reliable arc fault protection to enhance safety and compliance. The SuperFlex Design allows for complete flexibility in roof planning, while the Dynamic Peak Manager optimizes power harvest for maximum yields.

The Advanced models build upon the robust capabilities of the standard Symo, adding features that address Module Level Shutdown requirements, including an integrated PLC transmitter supporting the SunSpec Rapid Shutdown communication standard. These units meet NEC 2014 and 2017 requirements (as well as pre-2014 compliance), support zero-tilt mounting, and are both lightweight and field-serviceable for ease of maintenance.
