Equipment features

Grounding selectable on site.
Decide on site what type of grounding is required as the Fronius IG Plus is field programmable for either positive or negative module grounding.

Designed for indoor and outdoor installations.
All Fronius IG Plus inverters have a robust, well designed aluminum housing. UV resistance and corrosion protection enable them to be used either indoors or outdoors. Fronius is proud to be one of the only inverters tested and approved to operate at 122

Integrated DC disconnect.
No external DC disconnect installation or cabling is necessary. The Fronius IG Plus comes complete with an approved, built-in, lockable and load breakable DC Disconnect.

The new power plug system.
The connection area and power stages are installed separately from each other. Very easy and extremely safe: The connection area is attached to the wall as normal. Then the power module is simply plugged in. The power plug connects both parts into one secure unit. If service is required, the connector remains on the wall maintaining all settings and configurations.

Field Programmable AC output voltage.
The Fronius IG Plus inverter line from 3.0 to 11.4 kW is field programmable to 208, 240 or 277 volts (Fronius IG Plus 12.0 kW only availabale in 277 volts), eliminating the need to install different inverter models to accommodate three-phase installations.

Technology
Three efficiency peaks.
Greater power harvest for every system size: The unique automatic transformer switching function of the Fronius IG Plus makes enables not one, but three equal efficiency peaks. The result: Consistantly high efficiency over a wide input voltage range.

In comparison: The efficiency of inverters without transformer switching declines steadily with an increasing input voltage. Devices without a transformer only have one efficiency peak.

With a 96.2 % maximum efficiency, the Fronius IG Plus series scores the highest grade among HF devices.

MIX™ Concept.
Get the maximum power harvest out of partial load ranges, e.g. on cloudy days, through a clever combination of multiple power stages in each inverter. The power stages in Fronius inverters divide up the work depending on operating hours and only operate as many power stages as required to efficiently process available power from the PV array.

Module Manager™.
The Module Manager keeps all Fronius IG inverters at the maximum power point (MPP) with fast and exact MPP tracking, ensuring that you get the most power out or each ray of sunlight. This is especially important for amorphous modules whose MPP can be more challenging to track.

Smart Ventilation Design.
Disruptive ambient factors such as dust or moisture remain on the outside: The reason: Cooling air is drawn in on the wall side and routed through a closed channel over the heat sink. This prevents contact with the circuit board. At the same time, the components are kept cool - the device operates with a stable consistency.

The First Universal Inverter

Versatility as a basic principle: The Fronius IG Plus works well with all PV modules and is suitable for all system sizes.

Compatible with all module configurations

The Fronius IG Plus works optimally with all module types, including amorphous modules. The Fronius IG Plus works well with all module types because of its wide input voltage range, galvanic isolation, field programmable grounding option, and its precise MPP tracking feature.

Grounding selectable on site

Decide on site what type of grounding is required as the Fronius IG Plus is field programmable for either positive or negative module grounding.

Designed for indoor and outdoor installations

All Fronius IG Plus inverters have a robust, well-designed aluminum housing. UV-resistance and corrosion-protection enable them to be used either indoors or outdoors. Fronius is proud
to be one of the only inverters tested and approved to operate at 122º F.

Field programmable AC output voltage

A small transformer with high output and efficiency

IG Plus 7.5 UNI 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%.

Regulated forced ventilation

Fronius IG Plus 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.
