    B ) Fix the screws on the rail. Mounting Torque : 9 N·m C ) Hang the microinverter on the screws, and tighten the screws. The silver cover side of the microinverter should be facing the panel. © 2022 Hoymiles Power Electronics Inc. All rights reserved.
  • Page 14 A ) Select the appropriate AC Trunk Cable according to the spacing between microinverters. The connec- tors of the AC Trunk Cable should be spaced based on the spacing between microinverters to ensure that they can be properly matched. (Hoymiles provides AC Trunk Cable with different AC Trunk Con- nector spacing.) B ) Determine how many microinverters you plan to install on each AC branch and prepare AC Trunk Connectors accordingly.
