The 40 mm version of the Enphase Frame Mount (Compatible with IQ Series) makes it easier to connect an IQ Micro Inverter to a solar panel with a 40mm frame. There is also a version for 35mm frames. The clamp consists of only two parts. One that attaches to the inverter and the other is positioned over the frame. The pair, with the frame in between, is then tightened with a cap screw, securing the whole thing. Not only does this result in less parts and thus saves costs from purchasing mounting material, the system is also quick and easy.
