Description
Description
The transformerless Fronius Symo is the ideal compact three-phase solar inverter for commercial applications of all sizes. The Fronius Symo is the clear commercial choice: boasting power classes from 10 kW to 24 kW, necessary features fully integrated, Fronius SuperFlex Design with dual MPPT, and a streamlined installation process. The SnapINverter hinge mounting system, lightweight inverter and easy commissioning app make installation possible in under fifteen minutes. Several industry-leading features are available with the Fronius Symo including Wi-Fi and SunSpec Modbus interfaces for seamless monitoring and datalogging (with integration of Fronius Datamanager 2.0 card in one per 100 units), field proven Arc Fault Circuit Interruption (AFCI), NEC 2014 compliance, and Fronius’ superb online and mobile monitoring platforms. Also field serviceable, The Fronius Symo is the most communicative, efficient, sustainable and streamlined three-phase string inverter available on the market.
Information:
The Fronius Symo, transformerless three phase inverter suits solar PV systems of all sizes. Maximum flexibility in system design is guaranteed with the high system voltage, wide input voltage range and unrestricted use indoors and outdoors. The Fronius Symo Light comes with the option of installing an additional interface card allowing system owners to connect to the internet monitoring system. This can be done through any internet ready device anywhere around the world, giving system owners complete visibility and control.
UNIQUE FRONIUS PC BOARD REPLACEMENT PROCESS
Fronius Service Partners are able to deliver fast inverter servicing due to the unique way the Fronius Symo range has been developed. These units have been designed specifically to make replacing PC Boards quick and efficient to minimise the amount of down time of the system.
SNAPINVERTER
The innovative hinged system design of this inverter offers a simple installation and servicing process for the user. The connection and power stage set compartments are installed separately with the connection compartment and the cables mounted to the wall first, followed by the power stage set compartment. This means when servicing the unit there is no need to detach the whole inverter; only the power stage set compartment needs to be removed, leaving cables, settings and configurations in place.
OPEN DATA COMMUNICATION
Fronius have made their inverters connect easily to the communication platforms offered by third party suppliers. The open Modbus TCP SunSpec standard protocol provides a simple way of establishing a data connection to other systems. This is achieved by using the existing Ethernet interface giving reliable communication.
SMART GRID READY
Fronius have future-proofed their technology by equipping their inverters for the Smart Grid of the future. Advanced Grid features have been built into these inverters, these include control functions for optimum feed-in of reactive/effective power. This functionality allows for stable grid operation even in circumstances when the solar PV density is very high and yield losses can be a resulting factor. This helps ensure the return of your PV system.
