The FRONIUS IG 3000, 3000 watt grid-tie photovoltaic inverter utilizes high frequency architecture to deliver higher reliability and performance while reducing size, weight and installation cost.

The Fronius IG series has proven itself to be powerful, user-friendly and highly reliable. Equipped for every size of PV system, especially for smaller systems (e.g. on the roof of a one-family home). The combination of different types available for selection is limitless. The ingenious processor control combined with the powerful HF transformer extracts the maximum energy yield from all types of modules.

All manufacturing, assembly and testing of the FRONIUS IG inverters occurs at Fronius' ISO 9001 factory. The result – superior quality control, high product availability, and quick response time.

Plug-n-Play Digital Technology

Just like your Personal Computer, FRONIUS IG inverters come with 3 user interface slots that allow you to add features, such as external sensors and remote displays, to your FRONIUS IG at any time. You can also connect to your IG via laptop or PC to update your inverter with new state of the art features and technology advances as they become available.

Active Cooling

For high reliability, long life and the ability to operate at full power over a wide range of temperatures, inverter 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.

Easy Installation

Each inverter comes with a separate quick mounting bracket. With its lightweight and compact design the FRONIUS IG can be easily lifted on or off of the bracket. Standard knockouts, built in AC/DC breakers (optional) and terminal strip saves time and expense when making electrical connections.

High Frequency (HF) Technology

High frequency technology is extremely compact and yet capable of transforming considerable power. Using an innovative Phase-Shift process the FRONIUS IG minimizes switching losses and is able to generate ultra high conversion efficiencies of 94.4%!
