sunMAX - Install: Mounts & Trim Kit (First Row)


The purpose of the Mounting Assembly is to support the AC Modules at a fixed, continuous height across the array. The Trim Kit (CoverLock) is installed across the bottom rows of modules to improve the appearance of the Array on the customer rooftop. Together, this mounting hardware is used for the FIRST ROW of mount points.

Note: In the next KB article/video, you will install mounting hardware for separate rows.


1. Using the mounting hardware, use the mounting bolts to attach mounting assemblies to both outer-location roof mounts installed in the front row of your solar array. Each Mounting Assembly has an arrow on the top surface of the 360° swivel that should always face forward toward the trim cover.




2. The mounting base and swivel portion for each mounting assembly should be facing towards the front as shown.

Note: You may need to adjust the position of the mounting assemblies as you proceed, so you can leave the mounting bolts slightly loose for the time being.



Leveling the Mounting Assemblies
Using leveling string, tie a knot around the first mounting assembly stud, just below the swivel portion of the mounting assembly. Ensure that the top portion of the stud can be seen through the opening of
the mount swivel.



3. Pull the leveling string up and over the top of the mount swivel, extending it all the way to the last mounting assembly in the row.



4. Once the last mounting assembly has been reached, pull the leveling string over the top surface of the mount swivel and tie another knot around the mounting assembly stud as performed in step one. (Note: Apply some tension to the string to create a leveling guide between the first and last mounting assemblies.)

5. At both ends of the leveling guide, measure the height between the string and the surface of the roof structure. If the height is not the same at both ends, turn the mounting swivel to adjust the height so they are the same. To raise the height, turn the mounting swivel counterclockwise. To lower the height, turn the mounting swivel clockwise.



6. Once the first and last mounting assemblies in that row are the same height, adjust the remaining mount assemblies by turning the mount swivels (clockwise or counterclockwise) until they are the same height and position as the leveling string.



7. Secure and tighten each mounting assembly bolt (19 N-m torque) and remove the leveling string before installing the trim cover.

Trim Cover Installation

With all of the mounting assemblies now at the same height, install the trim cover by following these steps:

1. Hook the trim cover over the top lip of the mounting assemblies by placing it horizontally across the mount swivels in row one and rotating it down until it comes to a stop.



2. The trim covers are sized to fit the AC Module edges and should be positioned to support each location the AC Modules will be installed. Make sure each trim cover is fully seated on the mounting assemblies in that row. If more than one trim cover will be installed, position each additional one side-by-side until the front row is complete.




Trim Lock Installation

Once the solar trim covers are installed, secure each to the mounting assemblies by installing a trim lock on each mounting swivel.

1. Place and hold the trim lock up against the side of the mounting assembly and align it underneath the hole located in the mounting swivel.



2. Holding the trim lock in place, insert the trim lock screw through the top of the mounting assembly and secure the trim lock to the mount swivel. The trim lock will also will also secure the trim cover to the mounting assemblies in row one.




Panel Connector Installation for Trim Cover

Prior to installing the first row of AC Modules, panel connectors need to be inserted along the trim cover at all locations where AC Modules will be installed. If the first row in your solar array will consist of more than one trim cover, you will also use a panel connector to join together the ends of side-by-side trim covers.

Each panel connector has an arrow on its top surface, marking the center point that should be aligned with each of the following:

  • The alignment mark on all 2-panel portrait trim covers.


  • The joining line created by the installation of two trim covers installed side-by-side.
