Fronius features advanced high-frequency technology that delivers high-efficiency, precision Maximum Power Point Tracking MPPT in a lightweight design.
Active cooling delivers full power from -4° to 122°F; voltage input range of 150V to 450V permits flexible array sizing.
Though Fronius strongly encourages system designers and installers to avoid shading as much as possible, the net effects of using the Fronius IG inverter with a shaded array vs. two separate units or a unit with separate MPPT tracking functions is less than 1%.
The Fronius IG also outperforms other inverters in situations that involve similar strings at different angles.
Backlit LCD display shows: instant AC output, daily output, output since installation, CO2 emissions avoided and more, including fault displays for quick repairs.
