Three efficiency peaks. The unique automatic transformer switching function enables not one, but three efficiency peaks resulting in consistently high efficiency over a wide input voltage range.

The Mix™ Concept on the 2 and 3 power stage inverters allows maximum power harvest out of partial load ranges, e.g. on cloudy days, through a clever combination of multiple power stages in each inverter.

The optimized Module-Manager™ Software enables even more efficient MPP-tracking which is especially important for systems with thin film modules who's MPP can be a bit more challenging to track.

Smart ventilation design keeps disruptive ambient factors away from the circuitry by drawing cool air through a filter screen on the back of the inverter where it is routed through a closed channel over the heat sink. This prevents contact between outside air and the circuit boards, while cooling the inverter components.

The new power plug system allows for easy installation and service work by the separate mounting of connection-area and power stage unit. If service should be required, the connection compartment remains on the wall maintaining all settings and configurations.

The Fronius IG Plus comes complete with an approved, built-in, lockable and load breakable DC Disconnect. Grounding selectable on-site, and field programmability of the AC output voltage are additional benefits.
