Low Voltage, High Power

The Fronius IG 4500 LV 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 94.4%, this inverter is a great value.

The IG 4500 LV is compatible with all solar panels and 208V AC utility power. This flexible compatibility is because of the wide input voltage range of Fronius inverters - from 150 to 450V. This wide input voltage range allows you to choose from virtually any solar panel on the market.

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 grid-tie solar systems.  Different inverter types may be combined as required allowing flexibility and scalability for the future. Time proven Fronius technology gets the most out of all solar panel types.

You can count on the Fronius IG 4500 LV for:

  • Maximum yield dependability
  • Exceptional reliability
  • Ease of installation

Fronius IG 4500 LV Review

The Fronius IG 4500 LV is a powerful, user-friendly and highly reliable solar grid-tie inverter designed for 208V AC home grid-tie solar systems. Equipped for every size of grid-tie solar system, especially for smaller systems (e.g. on the roof of 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. 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.

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 4500 LV 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 higher current produced by many high-output solar cells are no problem for a Fronius IG inverter. 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.

MIX™ Concept Technology

Get the maximum power harvest out of partial load ranges, e.g. under shady trees, through a clever combination of multiple power stages in each inverter (known as the MIX™ Concept). The power stages in Fronius inverters divide up the work depending on operating hours and only operate as many power stages as required for maximum solar power harvest from the solar array.
