C) Hang the microinverter on the screw (as shown in the picture), and tighten the screw. The silver cover side of the microinverter should be facing the panel.

*Note: Please install the microinverter at least 50 cm above the ground/roof for better communication with the Hoymiles DTU.

Step 2. Connect AC Cables of Microinverter

A) Plug the AC connector of the first microinverter into the connector of the second microinverter to form a continuous AC branch *circuit. Note:** The length of the AC cable on the microinverter is around 2.04 m. Use AC extension cable if two microinverters are more than 2.04 m apart. hoymiles HM 800
