The IG-4000 Inverters from Fronius utilize high frequency, phase-shift architecture to deliver 4,000 watts of high performance, while reducing size, weight, and installation cost.

Fronius has built a lightweight inverter that can withstand the test of time regardless of harsh environments and heavy use. The IG-4000 weighs only 42 pounds, making it the lightest grid-intertied inverter you will find on the market.  Fewer raw materials are required to build each Fronius IG, therefore less CO2 emissions are produced and less material that will end up in a landfill someday.

Lightweight also means that it costs 2 to 3 times less to ship a Fronius IG inverter, saving you money and using less fossil fuels to get the Fronius IG from our warehouse to your photovoltaic installation. Keep up the conscious effort to eliminate the threat of pollution.
