A family business founded in 1945, Fronius now has over 1,400 employees and is a successful international system provider for welding systems.
Fronius has been engaged in solar electronics since 1992, in particular in the development and production of photovoltaic inverters for both grid-connected and independent power supplies. Meanwhile Fronius have a large number of renowned manufacturers and wholesalers of solar modules amongst our satisfied customers. Thanks to solar electronics Fronius has advanced to the ranks of the worldwide leading manufacturers and continues to develop its position through ongoing product innovations. State-of-the-art technology in high-performance electronics, a higher level of integration through the use of high-capacity processors and the interconnection of stand-alone devices by using modern means of communication are the key to our success. Fronius is optimally prepared in each of these fields.
The young divisions of solar electronics - in the meantime Europe's second largest manufacturer of solar inverters with an increasing market share - as well as battery chargers are considered innovative models of their branch.
Innovation is firmly rooted in the Fronius corporate philosophy and on-going development of high tech quality products reflects the importance of this basic value.
FRONIUS IG 2000
The FRONIUS IG 2000 photovoltaic inverter utilize high frequency, phase-shift architecture to deliver higher reliability and performance while reducing size, weight and installation cost.
For high reliability, long life and the ability to operate at full power over a wide range of temperatures, inverter components must be kept cool. Fronius, which perfected Active Cooling in HF welders, employs the same Active Cooling technology in its IG inverters. FRONIUS IG inverters operate reliably at full power, without de-rating, over a wider range of temperatures than competing inverters.
Features:
• Lightweight, only 26 lbs. (11.5 kg), makes installation a one-man job and reduces shipping cost
• Easy and fast installation due to mounting brackets
• Integrated DC/AC disconnects reduce time during installation and costs
• Wide input voltage range permits the use of modules of every power size and voltage
• Large LCD display comes standard
• Maximum power point tracking (MPPT) accuracy of 99.9%
• High efficiency
Basic Electrical Features*
• Peak Efficiency: 94.4%
• CEC Efficiency: 93.50%
• Recommended PV Power: 1500 – 2500 Wp
• Operating DC Voltage Range : 150 – 500 V
• Max AC Power: 2000W
• AC Operating Voltage: 240V
*Specifications subject to change.

FRONIUS IG 4000
How much power can you handle?
Now you can handle a lot more, thanks to the new Fronius IG 4000 grid tied inverter that output up to 4000 Watts but still weighs only 42 pounds. The key is that these units use the same proven hardware and software as the 60,000 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 IGs' load-sharing ability.
Features:
• Lightweight, only 41.8 lbs. (19 kg), makes them easy to install
• MIXTM concept allows your system to output more energy under
• Integrated DC/AC disconnects reduce time during installation and costs
• Large LCD display comes standard
• High efficiency
• Plug-and-Play: Expansion slots in the inverter allow you to easily upgrade the inverter with a complete data communication solution.
• Maximum power point tracking (MPPT) accuracy of 99.9%
Basic Electrical Features*
• Peak Efficiency: 94.4%
• CEC Efficiency: 94%
• Recommended PV Power: 3000 – 5400 Wp
• Operating DC Voltage Range : 150 – 500 V
• Max AC Power: 4000W @40°C
• AC Operating Voltage: 240V
