Fronius IG Plus 3.0 Inverter

Availability: Call For Availability

Quick Overview


IG Plus Series Inverters
The first complete inverter solution. Reliable. Proven. Smart.


An outstanding addition to the family
The next generation Fronius IG Plus inverter builds on a successful model with multiple enhancements, including maximum power harvest, a built-in six circuit string combiner, integrated, lockable DC Disconnect, significantly improved efficiency, and unbeatable reliability.


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.


Fronius IG Plus Inverter designDesigned 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° F.


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
This Fronius IG Plus inverter line from 3.0 to 3.8 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.

Fronius' 20 years of experience with forced ventilation brings a number of advantages:

A small transformer with high output and efficiency

inverter transformerThe 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.

Fronius IG Module-ManagerOutput 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.

Fronius IG graphic displayThe 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

AC and DC disconnectsEach 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.
