FRONIUS SYMO
/ Powering commercial projects that last. The Fronius Symo.
/ Featuring ten models ranging from 10 kW to 24 kW, the transformerless Fronius Symo is the ideal compact three-
phase inverter for all commercial applications. The high system voltage and wide input range ensure maximum flexi-
bility in system design. With low roof loading, NEMA 4X and 1000 V DC rating, the Fronius Symo can be mounted in
many different ways, including flat on a roof or on a pole. The modern design is equipped with the SnapINverter
mounting system, allowing for lightweight, secure and convenient installation. Several industry-leading features are
available with the Fronius Symo including Wi-Fi
®
* and SunSpec Modbus interfaces for seamless monitoring and data-
logging, field proven Arc Fault Circuit Interruption (AFCI), NEC 2014 compliant, and Fronius’ superb online and mo-
bile monitoring platform Fronius Solar.web.
