Fronius' 20 years of experience with forced ventilation brings a number of advantages:
A small transformer with high output and efficiency
The power stage is based on the use of high frequency (HF) technology. The HF transformer is extremely compact, yet capable of transforming considerable power. The innovative phase shift process used in the Fronius IG series also minimizes switching losses thereby ensuring a high degree of both efficiency and flexibility in terms of the unit's capacity.
The unique Phase-Shift process minimizes switching losses and is able to generate ultra-high conversion efficiencies of up to 96.2%.
Regulated forced ventilation
Fronius IG grid-tie inverters are equipped with a top-of-the-range cooling fan making it possible to use an extremely small heat sink which is mounted directly on the board.
Fronius' 20 years of experience with forced ventilation brings a number of advantages.
Simple maintenance, reduced levels of so-called grey energy and a notable reduction in weight mean savings both for the environment and your wallet. The cooling fan is only switched on when needed thereby not using any energy while the temperature of the power stage semiconductors is low. This configuration also extends the life of the cooling fan significantly.
Output vs. voltage, the Fronius IG Module-Manager
Whatever solar panel array you decide on, whether monocrystalline, multicrystalline or thin-film, the Fronius IG inverter always fits perfectly in the system-concept. The "Module-Manager" is software integrated into each Fronius IG inverter that optimizes the earnings of your system in each and every situation. The Module-Manager does a first class job and leads to optimal results.
The higher current produced by many high-output solar cells are no problem for a Fronius IG inverter. This is because of the wide input voltage range of Fronius inverters - from 150 to 450V. Because of this wide input voltage range you can choose from virtually any solar panel array on the market. This feature also ensures the optimal use of the roof space without limiting architectural options.
The Fronius IG graphic display
The built-in display on a Fronius IG is your personal communication with your entire solar grid-tie system. System information can be read directly on the inverter. The most relevant parameters can be read immediately so that you always know what is going on. The simple display navigation makes getting this information very easy!
Mounting & Connection
The Fronius IG inverter has several features that make installation extremely simple and convenient.
Mounting Frame - practical and simple
Not only does the the light weight of your Fronius IG make the installation easy and convenient, every inverter comes with an additional mounting frame. After installing this frame on the wall you can easily hang up your inverter.
AC and DC disconnects built-in
Each Fronius IG comes with built-in AC and DC disconnects and in many cases eliminate the need for external breakers. This reduces installation time and total system costs. With its lightweight and compact design, this inverter series can be easily lifted on or off of the bracket. Standard knockouts and terminal strips save time and expense when making electrical connections.
As soon as a Fronius IG inverter has been installed, it is immediately ready to do its job. All relevant safety settings have been pre-programmed. Just switch on your Fronius IG inverter and watch it work.
