The IG-5100 inverters from Fronius utilize high frequency, phase-shift architecture to deliver high performance while reducing size, weight, and installation cost.

Features and General Information

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.

Active Cooling- The 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..

Fully programmable operation

The Fronius 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.
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.

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 Fronius IG series is 150--500Vdc.
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.
