Fronius IG Plus and IG Plus V

New generation PV inverters

Fronius MIX™ concept

Maximum power harvest out of partial load ranges, e.g. on cloudy days, through a combination of multiple power stages in each inverter. The power stages divide up the work and only operate as many as required to efficiently process available power. Should one module fail, the others continue to function.

Installation

The power-plug system allows the connection and power stage compartments to be installed separately. During installation, only the connection compartment needs to be mounted onto the wall. Once all connections are done, simply plug-in the power stage(s) to the connection compartment.

Smart Ventilation Design

Ventilation design keeps ambient factors such as biological infestations, dust, moisture, or coastal salt air outside of the Fronius IG Plus inverters and away from the circuitry. Cool air is drawn in through a filter screen on the back of the inverter and routed through a closed channel over the heat sink. This prevents contact between outside air and circuit boards while cooling the inverter components. Circuit boards are also dipped in Conformal coating.

Power Stage Replacement

The new Power-Plug system for the Fronius IG Plus series facilitates installation and simplifies any required future servicing work. The power stage compartment can be exchanged on-site by a certified service provider. The connection compartment, including cabling and all configurations, remains on the wall.
