Description

The Fronius Symo 12.5-3-M Light 12.5kW Solar Inverter is designed for maximum flexibility for the solar pv applications of tomorrow. With power categories ranging from 3.0 to 20.0 kW, the transformerless Fronius Symo is the three-phase inverter for systems of every size. The high system voltage, wide input voltage range and two MPP trackers ensure maximum flexibility in system design. The standard interface to the internet via WLAN or Ethernet and the ease of integration of third-party components make the Fronius Symo 12.5kW one of the most communicative inverters on the market.

SnapINverter mounting system

The innovative SnapINverter mounting system makes installation and servicing extremely user-friendly. It is not necessary to remove the entire inverter for servicing, just the power stage set compartment. All the cabling, settings and configurations remain in place.

SuperFlex Design

The Fronius SuperFlex Design combines all the system design requirements into a single inverter form. Two MPP trackers combined with a high system voltage and wide input voltage range guarantee maximum flexibility.  The result: an inverter for every application. Thanks to the SuperFlex Design, a single inverter can cope with any challenge – including different roof orientations, shading of one or two strings, or the use of residual modules.

Dynamic Peak Manager

The Dynamic Peak Manager is a new MPP tracking algorithm searching for the optimal operating point. The special feature is that the Dynamic Peak Manager automatically checks the entire characteristic curve on a regular basis and finds the global Maximum Power Point (GMPP), even in partial shade.

The Fronius Symo 12.5-3-M Light 12.5kW Solar Inverter is Smart Grid Ready

Fronius inverters are ready for the Smart Grid of tomorrow. The inverters are optimally equipped to meet the technical requirements of grids in the future. A series of smart functions, known as Advanced Grid Features, are built into the devices. These include a number of control functions for optimum feed-in of reactive power and effective power.

Zero feed-in

In various countries power grid operators require a PV power feed-in limit as a precondition before connection. With dynamic power reduction, Fronius is offering a solution for optimum feed-in management. The Fronius Symo 12.5-3-M Light 12.5kW Solar Inverter allows zero feed-in into the grid. This meaning that no PV power is fed into the grid. The relevant requirements of the grid operator can be fulfilled by simply enabling a setting on the inverter’s web interface.

The history of the Austrian Fronius begins in 1945. At that time, charging car batteries was not something that could be taken for granted. Günter Fronius was unwilling to accept this. In 1950, Günter Fronius expanded his product portfolio to include welding transformers. Driving forward their growth and internationalisation strategy saw the establishment of subsidiaries around the world. In 1992, the decision was taken to focus on the “future field” of solar energy, which is why the company today is split into three strong divisions: Perfect Welding, Solar Energy and Perfect Charging.
