Alpha Solar: Fronius IG inverters, IG2000, IG3000, IG 2500LV, IG 4000, IG 5100, IG 4500 LV

The FRONIUS IG inverters offer high efficiency, precision MPP-tracking, and
active cooling, all of which result in superior energy output from grid-tied
photovoltaic systems. FRONIUS IG inverters are less than half the
weight of competing inverters. High frequency technology is compact and
capable of transforming considerable power. Using an innovative Phase-Shift
process, the Fronius IG minimizes switching losses. Built-in DC and AC
disconnects eliminate the need for external disconnects in many cases,
reducing total system costs. Fronius IG inverters come standard with an
integrated LCD where the installer can view and record over 20 parameters
pertaining to inverter and system operation. Optional remote data
communications and data logging features can easily be added via
Plug-n-Play cards to transform IG inverters into a sophisticated data
acquisition system and weather station. Outdoor rated unit,

Regulated forced ventilation
FRONIUS IG solar inverters are equipped with a top-of-the-range cooling fan making it possible to use an extremely small heat sink which is mounted directly on the board. 20 years experience with forced ventilation brings a number of advantages.
Simple maintenance, reduced levels of so-called grey energy and a notable reduction in weight mean savings both for the environment and your wallet. The cooling fan is only switched on when needed thereby not using any energy while the temperature of the power stage semiconductors is low.

Whatever module you decide for, the FRONIUS IG inverter always fits perfectly in your system-concept. The FRONIUS IG Module-Manager is a software already integrated in each FRONIUS IG that optimizes the earnings of your system in each and every situation because of the wide input voltage range of our inverters ranges from 150 to 500V. Because of this wide input voltage range you can choose every module available on the market. This feature also ensures the optimal use of the roof space without limiting architectural options.

The FRONIUS IG graphic display - Information directly on the inverter
The display at your FRONIUS IG is your personal communication with your entire photovoltaic system. The most relevant parameters can be read immediately so that you always know what is going on. Additionally, the simple display navigation eases the provision of information. The display is the interface between you and your PV-system.

Reliable-Rugged-Built to Last -over +125,000 units in operation throughout the world.

High efficiency with intelligent thermal management maximizes energy yield

Large LCD display standard on all models

Integrated DC/AC disconnects reduce installation time and cost

Wide Input Voltage Range allows greater system design flexibility

The FRONIUS IG 2000,IG 3000 and IG 2500-LV (low voltage 208V) photovoltaic inverters utilize high frequency architecture to deliver higher reliability and performance while reducing size, weight and installation cost.

Now you can handle a lot more, thanks to the new Fronius IG 4000, IG 4500-LV (low voltage 208V) and IG 5100 grid tied inverters that output up to 5,100 Watts but still weigh only 42 pounds. The key is that these units use the same proven hardware and software as the 125,000 IG units already operating worldwide. It's like having two inverters in one easy-to-install box, but with the advantages of even greater part-load efficiency and increased longevity due to the new IGs' load-sharing ability.
