Description
The transformerless, three-phase Fronius Symo Advanced 12.0-3 string inverter handles up to 15,500 Watt DC input and delivers 12,000 Watt AC output for commercial solar installations with a 208V - 240V, 3-phase grid connection. The high system voltage and wide input range ensure maximum flexibility in system design. The new Advanced versions combine the benefits of the Fronius Symo with additional value for states with Module Level Shutdown requirements including integrated PLC transmitter for SunSpec Rapid Shutdown communication standard, compliance with NEC pre-2014, 2014 and 2017, zero tilt mounting, light weight and field serviceability.
With low roof loading, NEMA 4X and 1000 V DC rating, the Fronius Symo Advanced can be mounted in many different ways, including 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 2017 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
