All Fronius IG Plus Advanced, Galvo, and Primo inverters carry a 10-year warranty, with an optional 15-year warranty.

Fronius manufactures three major types of grid tie solar inverters: The IG Plus Advanced, The Galvo, and The Primo.

The latest and greatest Fronius grid-tie inverters are the IG Galvo and Primo lines, which are fully NEC 2014 and UL compliant. They come with built-in ground fault protection, DC reverse polarity protection, islanding protection, over temperature protection, and arc-fault circuit protection. If you're interested in three-phase models, the Symo inverters will meet your needs. Fronius inverters are available in both single phase and three phase AC models, which makes them suitable for both residential and commercial applications.

The newest Galvo and Primo inverters also come standard with Wi-Fi capability with included web monitoring via the Solar.web portal. Designed for single-phase AC, small to medium-sized residential applications.

Fronius IG Plus - The first complete inverter solution.

An outstanding addition to the family: The next generation Fronius IG Plus inverter builds on a successful model with multiple enhancements, including maximum power harvest, a built-in six circuit string combiner, integrated, lockable DC Disconnect, significantly improved efficiency, and unbeatable reliability. New, larger power stages expand the proven Fronius IG family from 2 to 12 kW in a single inverter.

At only 26 lbs, the Fronius IG 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 pre-drilled and patterned for mounting to a single stud, flat wood or stucco siding, 6" and 8" lap siding, and shingles. Integrated DC/AC disconnects reduce installation time and cost.

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 (four input strings). Large LCD display standard on all models. Each FRONIUS IG comes standard with an integrated LCD display to allow users easy access to a wealth of system information, including:

  • Instantaneous AC Power to the Grid
  • Total Energy Savings for Day/Since Start Date
  • Total CO2 Emissions Avoided in lb
  • Peak DC voltage
  • Peak AC Power
  • Min./max. AC voltage

High efficiency with intelligent thermal management maximizes energy yield. The Fronius IG inverters combine several key design elements to ensure operation at a high efficiency under all operating conditions. MPPT accuracy of 99.9%- Regardless of which PV modules you use; crystalline, poly or thin film, the FRONIUS IG Module Manager software locks onto the array's maximum power point to optimize the energy output from your array. Accurate MPP tracking and high efficiency are maintained throughout the voltage and power range.

Active Cooling - To operate at full power over a wide range of temperatures, inverters 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. 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. Wide Input Voltage Range allows greater system design flexibility.

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 IG series is 150-450Vdc. Reliable-Rugged-Built to Last -over +60,000 units in operation throughout the world. FRONIUS IG inverters are built in an ISO 9001 facility. As a world-leading manufacturer of HF welding equipment Fronius builds products that can withstand the test of time in harsh environments and heavy use. That know-how is built into each and every IG inverter. Built to last by a company that has been around long enough to know.

FRONIUS "LocalNet"

FRONIUS "LocalNet" is an in-house developed data communication system, which is noted for flexibility and stability. LocalNet devices connect to one another via the RS 485 interface using standard Cat5 networking cables. Once connected it is possible to transfer large volumes of data across long distances and all LocalNet devices can be conveniently accessed and managed from a PC computer.

Fronius IG Plus Advanced Grid-Tie Inverters

Fronius IG Plus Advanced - The first NEC and UL compliant grid-tie inverter solution.

The Fronius IG Plus Advanced is the first complete inverter lineup of the NEC 2011 compliant AFCI protected inverters in the United States. Power classes ranging from 3 to 12 kW in both single and true 3 phase applications with integrated Fronius MIX Technology and wide voltage windows are the perfect match for your system design.

The IG Plus Advanced have many improvements over the older IG, such as being configurable for either standard household 120/240 volt service, or for 208 Volt 3-phase commercial and industrial service. The IG Plus V inverter line is going to be phased out for the newer IG Plus Advanced models.

Fronius IG Plus Advanced grid-tie inverters are fully NEC and UL compliant. They come with built-in ground fault protection, DC reverse polarity protection, islanding protection, over temperature protection, and arc-fault circuit protection. Available in both single phase and three phase AC models, they are suitable for both residential and commercial applications.
