FRONIUS INVERTERS FOR GRID CONNECTION

Fronius have three models of grid connect inverters. They are known as the Fronius IG, Fronius Plus and Fronius IG TL range of inverters.
The Fronius IG range offer maximum flexibility as they work with all makes of solar panels available on the market. Built with an ingenious processor control - the Fronius IG Module-Manager™ - and a large number of other enhancements makes them into the perfect all-rounders. The IG range is reliable and efficient.
The Fronius IG Plus Range are the next generation of inverters and expand the power of the IG range from 3.5 to 12kW.
The Fronius IG TL incorporates all the advantages of a transformerless inverter concept with the high innovation and quality demands of Fronius. They are perfect for system sizes ranging from single-family homes up to agricultural or commercial operations. Unique in its class is the standard system monitoring which makes it the most future-proof transformerless inverter providing maximum earnings security.

| FRONIUS IG15 | The Fronius IG series has proven itself to be powerful, user-friendly and highly reliable. Equipped for every size of PV system, especially for smaller systems (e.g. on the roof of one-family houses). The combination of different types available for selection is limitless. The ingenious processor control combined with the powerful HF transformer extracts the maximum energy yield from all types of modules. The FRONIUS IG 2000,IG 3000 and IG 2500-LV (low voltage 208V) photovoltaic inverters utilize high frequency architecture to deliver higher reliability and performance while reducing size, weight and installation cost. Follow the links below to find out more about features that improve the performance and reduce the cost of your PV system.

| FRONIUS IG 40 / 60 | Now you can handle a lot more power, thanks to the new Fronius IG 4000, IG 4500-LV (low voltage 208V) and IG 5100 grid tied inverters that output up to 5,100 Watts but still weigh only 42 pounds. The key is that these units use the same proven hardware and software as the 200,000 IG units already operating worldwide. It's like having two inverters in one easy-to-install box, but with the advantages of even greater part-load efficiency and increased longevity due to the new FRONIUS IGs' load-sharing ability. You also get everything you would expect from the leader in inverter technology:

| FRONIUS IG Outdoor | The Fronius IG Outdoors has been created specially for use in the open air and has been tested to an IP45 degree of protection. This ensures a continuous circulation of air that prevents condensate from collecting. The inverter is also protected against the entrance of solid particles and hose water. It is also reliable and safe to use near the sea due to a special protective coating applied to the printed circuit boards within the inverter. The Fronius IG Central Inverters are optionally available in a housing tested to an IP43 degree of protection, what means that these inverters can also be used for outdoor application. |

| FRONIUS IG Central Inverters | The FRONIUS IG central inverters are suitable for pv systems starting with an AC output power of 24 kW and work with a completely new system configuration. There is not only one power stack converting the electricity but also 9, 12 to 15 printed circuit boards that share the work, depending on the output class. The reason for this is that it is well-known that the energy yield increases in part-load areas if smaller power stacks are operated at higher capacity. Therefore, every FRONIUS IG central inverter works with several smaller power stacks that switch on or off completely automatically depending on irradiance so that they can always deliver maximum power. |

All Fronius inverters include precision MPPT tracking and are incredibly lightweight. Each inverter has built-in DC and AC disconnects and in many cases eliminates the need for external circuit breakers thus reducing installation time and overall system costs. An active, on-demand cooling system, results in superior energy output from the PV system. Its lightweight and compact design means the Fronius IG can be easily lifted on or off of its mounting bracket. All Fronius IG inverters include an integrated LCD to record or view over 20 different parameters. The inverters can be mounted either indoors or outdoors. All Fronius IG inverters carry a standard seven-year warranty with an option for an additional three years of coverage
Also available:
Fronius IG DatCom – Remote data communications and data logging features can easily be added and will transform your Fronius IG inverter into a sophisticated data acquisition system and weather monitoring station. All data can be viewed on the IG inverter display and data from optional sensors can also be viewed on your PC. Data can be downloaded in real time, or cumulative for the day, the year, or since installation. One Datalogger Box is required per DatCom system. The Datalogger coordinates data traffic and stores the data collected from all Fronius IG inverters and sensors in your weather station. Connection to a PC or an external modem allows you to monitor your PV system from anywhere in the world. A communications card is required for each Fronius IG inverter in your DatCom system. This simply plugs into one of the available slots. The COM Card supplies power to the DatCom components.
Fronius IG Sensor Box – The Fronius IG Sensor Box allows you to collect even more information about your system. With 6 inputs, you can measure the array temperature, wind speed, irradiance, load, and numerous other types of data.
Fronius Interface Box – The Optional DatCom System is a feature that enables a user to output data into an open protocol for a system of up to 100 Fronius IG inverters. This data can then be used by a third party sources for different monitoring options. This unit does not replace the need for a Datalogger Box and enables a user to operate the DatCom System including the use of the Fronius IG online (free service allowing the user to monitor and analyze system performance). This interface offers real-time open protocol data without data storage and stores closed protocol data for use with Fronius IG access.
Fronius IG Personal Display – The Fronius wireless Personal Display shows data from the inverter on a remote LCD that can be placed anywhere in the home or office. The range is approximately 150 ft. indoors or 450 ft. outdoors. It can be used with up to 15 Fronius IG inverters - each inverter requires a Wireless Card. The Personal Display operates independent of the DatCom data communication system and can be used in tandem with it.
