Lightweight; 26 lbs total weight for the IG3000.  

• 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.
