Description
The transformerless, three-phase Fronius Symo 15.0-3 208 Volt string inverter handles up to 19,500 Watt DC input and delivers 15,000 Watt AC output for residential or commercial solar installations with a 208V, 3-phase grid connection. The high system voltage and wide input range ensure maximum flexibility 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 compact design is equipped with the SnapINverter mounting system, allowing for lightweight, secure and convenient installation. Several features are included with the Fronius Symo including Wi-Fi and SunSpec Modbus interfaces for seamless monitoring and data-logging, Arc Fault Circuit Interruption (AFCI), NEC 2014 compliant, and Fronius online and mobile monitoring platform Fronius Solar.web. Certified to UL 1741-SA (Rule 21) and FCC. Order online or PHONE 888-498-3331
