The IG-3000 Inverters from Fronius utilizes high frequency, phase-shift architecture to deliver 2,700 watts of high performance while reducing size, weight, and installation cost.

Features and General Information

• Regardless of which PV modules you use, crystalline, poly or thin film, there is a MPPT accuracy of 99.9 percent.
• The FRONIUS IG Module Manager ^TM software locks onto the array's maximum power point to optimize the output of an array.
• FRONIUS IG inverters operate reliably at full power, without de-rating, over a wider range of temperatures.
• Phase Shift Technology - Switching efficiency is maximized by a unique phase-shift design. Switching losses are minimized allowing an even higher efficiency to be maintained.
• Fully programmable operation
• The Fronius IG uses a high frequency transformer, which is substantially smaller than the 60 Hz transformers 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.
• We have optimized the output inductor to put two inductors on one coil. Many inverters use two separate inductors, which add up to a heavier inverter.
• A wide input voltage range permits the use of modules of very power size and voltage. You can easily fine-tune your system with different string configurations and wattage modules. The voltage window for the entire Fronius IG series is 150-450Vdc.
• Includes integrated DC and AC disconnects. Both DC and AC electrical connections are made in the convenient installer accessible wiring compartment. We have pre-wired the DC breaker to a heavy-duty terminal block that accepts up to eight #8 AWG conductors.
