The reliable PV inverter series.

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 one-family houses). 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.

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

The Fronius Module Manager always locates the maximum power point (MPP), even in the case of the more demanding thin-layer modules. The Fronius Module Manager achieves an outstanding MPP adaptation efficiency of >99.9 % in total.


PC board replacement

The foundation of the unique PC board replacement is laid as we develop our inverters, as PC boards can only be replaced if the device has been designed accordingly. This enables our Fronius Service Partners to provide the fastest inverter servicing on the market.
