Fronius IG 4000 inverter

Dependable and a great value

The Fronius IG 4000 Inverter is part of the Fronius IG family of inverters and represents an evolution of the proven Fronius IG product family. With a reliable maximum efficiency of 95.2%, this inverter is a great value.

The higher current produced by many high-output solar cells are no problem for a Fronius IG 4000. This is because of the wide input voltage range of Fronius inverters - from 150 to 450V. Because of this wide input voltage range you can choose from virtually any solar panel array on the market. This feature also ensures the optimal use of the roof space without limiting architectural options. They work reliably and efficiently in every class thanks to Fronius' incredible experience and decades of research and development.

Designed for indoor and outdoor installations
All Fronius IG inverters have a robust, well designed aluminum housing. UV resistance and corrosion protection enable them to be used either indoors or outdoors.

The Fronius IG line is perfect for smaller applications, such as residential utility intertie systems.  The different inverter types can be combined as required.  Time proven Fronius technology gets the most out of all solar panel varieties.

You can count on the Fronius IG 4000 for:

  • Maximum yield dependability
  • Exceptional reliability
  • Ease of installation

Fronius IG 4000 LV Review

The Fronius IG 4000 is a powerful, user-friendly and highly reliable solar grid-tie inverter. It is equipped for every size of solar system, especially for smaller systems (e.g. on the roof of one-family residences). 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 solar modules.

Equipment Features

  • Fronius LC-Display
  • HF-Transformer
  • Module-Manager
  • MIX™ Technology

HF transformer switchover 

Fronius transformer inverters use a high-frequency (HF) transformer. The automatic transformer switchover facility produces three efficiency peaks. The result: a constant level of efficiency across the entire input voltage range, resulting in higher yields. Other advantages of HF transformer technology are the compact, lightweight design, a high level of efficiency and safety as a result of the electrical isolation.

Fronius Module Manager 

Whatever solar panel array you decide on, whether monocrystalline, multicrystalline or thin-film, the Fronius IG 4000 inverter always fits perfectly in the system-concept. The "Module-Manager" is software integrated into each Fronius IG inverter that optimizes the earnings of your system in each and every situation. The Module-Manager does a first class job and leads to optimal results.

The IG 4000 is compatible with all solar panels. What makes this inverter even more appealing is the intuitive operation and ease of use, together with its highly informative analyses of system values in every situation.

MIX™ Concept Technology

Fronius MIX™ technology provides more yield.  Two power stages are combined in a single device.  Depending on the level of available power, either one or both power stages work together.  Advantages include higher yield during partial load conditions and significantly reduced operating hours.
