Fronius Ig3000 3000W Grid-Tie Inverter

It’s a whole new technology, but it’s easy to pick up.

The Fronius IG 2000 and IG 3000 photovoltaic inverters utilize high frequency, phase-shift architecture to deliver higher reliability and performance while reducing size, weight and installation cost.

• How can the Fronius IG be so much lighter weight than competing inverters?
  
• High Frequency
  The IG uses a high frequency transformer, which is substantially smaller than the 60 Hz transformers used in inverters with one-stage topologies. The transformer also provides galvanic isolation. Since transformers are largely made of copper and iron, that's a lot of raw metal that is no longer necessary.
• Active Cooling
  The use of active cooling means the heat sinks can be much smaller as well. Because the heat sinks are just large pieces of metal meant to conduct heat away from the inside of the inverter, smaller heat sinks means less metal and less weight.
• Inductor Optimization
  We have optimized the output inductor to put two inductors on one coil. Many other inverters use 2 separate inductors, which adds up to a heavier inverter.
• Lightweight Housing
  The IG’s housing is made of lightweight aluminum, which is significantly lighter than stainless steel while continuing to offer the necessary durability and corrosion resistance.
  

  Because we use less raw materials in building each Fronius IG, this means less CO2 emissions and less material to recycle down the road. Its light weight also means it costs two-to-three times less to ship an IG inverter. This means less fossil fuels consumed to get the Fronius IG from our production factory to your photovoltaic installation. And when it arrives, you’ll be able to pick it up. At 26 lbs, it’s a one-person job. The delivery person, warehouse handler, and installer will all appreciate your choice.

• Mounting Bracket makes installation simple and fast

  At 26 lbs, the Fronius IG weighs about the same as a large framed picture and does not require special bracing or a back plate to install. An aluminum mounting bracket comes standard with each IG, making installation fast and easy. Mount the aluminum bracket to the wall, slide the IG onto the positioning lip, and fasten the securing screws (included). The mounting bracket is predrilled and patterned for mounting to a single stud, flat wood or stucco siding, 6” and 8” lap siding, and shingles.
  

  Integrated DC/AC disconnects reduce installation time and cost Every FRONIUS IG comes standard with integrated DC and AC disconnects. Both DC and AC electrical connections are made in the convenient installer accessible wiring compartment. We’ve pre-wired the DC breaker to a heavy-duty terminal block that accepts up to eight #8 AWG conductors (four input strings). Our DC/AC disconnects are UL rated and meet the technical requirements of the National Electric Code for PV systems. See our FAQ section for further information. Large LCD display standard on all models Each FRONIUS IG comes standard with an integrated LCD display to allow users easy access to a wealth of system information, including: Instantaneous AC Power to the Grid Total Energy Savings for Day/Since Start Date in Total CO2 Emissions Avoided in lb Peak DC voltage Peak AC Power Min./max. AC voltage And many more…

  

  It is easy to navigate, with large clear digits, and backlight for easy reading (with automatic shutdown to conserve power). There is additional functionality when you add the DatCom data monitoring system with weather station sensors. Take a look at our demonstration.
  The LCD is also used to display three-digit service codes relating to non optimal operating , both momentary and those needing correction. Knowing what your system is doing helps insure that it will produce the maximum output now and in the future. Using the displayed service codes saves time and effort in troubleshooting, and allows installers and dealers to resolve many issues remotely.

  Optional DatCom data logging and remote sensors can be added to any system for more sophisticated and almost limitless data analysis using Fronius IG.access.

• High efficiency with intelligent thermal management maximizes energy yield

  The Fronius IG combines several key design elements to insure operation at a high efficiency under all operating conditions.

  MPPT accuracy of 99.9%- Regardless of which PV modules you use; crystalline, poly or thin film, the FRONIUS IG Module Manager tm software locks onto the array’s maximum power point to optimize the energy output from your array. Accurate MPP tracking and high efficiency is maintained throughout the voltage and power range.

  Active Cooling – To operate at full power over a wide range of temperatures, inverters 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.

  Phase Shift Technology- Unique phase-shift design maximizes switching efficiency. Switching losses are minimized through an innovative process, allowing an even higher efficiency to be maintained.
  

• Wide Input Voltage Range allows greater system design flexibility

  A wide input voltage range permits the use of modules of every power size and voltage. You can easily fine-tune your system with different wattage modules and string configurations. The voltage window for the entire IG series is 150-450Vdc.
  

• Reliable-Rugged-Built to Last -over +60,000 units in operation throughout the world.

  FRONIUS IG inverters are built in an ISO 9001 facility. As a world leading manufacturer of HF welding equipment Fronius builds products that can withstand the test of time in harsh environments and heavy use. That know- how is built into each and every IG inverter. Built to last by a company that has been around long enough to know.
