Fronius IG 300 / 400 / 500
 |
These central inverters convert solar energy into high-quality electricity on a large scale. This Fronius development, just like all others, has also been based on four central parameters:
- Optimum user-friendliness
- Maximum efficiency
- Unconditional reliability
- Professional system monitoring
The new series not only successfully integrates these features but also demonstrates new, amazing characteristics. The intelligent inverter concept and the built-in features make the series lighter, smaller, easier to install and easier than ever to maintain.

Equipment features
Ventilation Control.
The innovative ventilation system prevents unwanted heating and dust deposits.
Module Manager.
The intelligent Module Manager from Fronius quickly finds the maximum power point (MPP): the working point for maximum output. The yield is always the best available. This even applies to the thin-film modules that are particularly demanding in this respect.
Safety.
Electrical isolation ensures the highest level of safety. Due to the high-frequency technology, the space-saving transformer is capable of transmitting an extraordinary amount of power very safely.
Focus.
The display exhibits the intelligent communication interface between the PV-system and the operator on site. Operation is simple and selfexplanatory as with the smaller classes of inverters.
Interface.
The integrated Com Card with sufficient space for Datalogger and modem presents the best possible prerequisite for installing a professional PV monitoring system.
