This is an Open Box item: It was (slightly) damaged in shipping. The small plastic bracket that goes around the DC disconnect switch at the bottom was broken. It is a fully functional unit though, everything works as it should, and it comes with full Fronius factory warranty. Besides the plastic bracket there is no damage, and the inverter looks and works like any new inverter would. In fact, if you don’t know about the bracket you wouldn’t notice. For someone that can live with a small cosmetic blemish this is a great deal!

Please check the pictures, they are of this unit and show the issue.
