Trim Cover Installation

Trim Cover Installation With all of the Mounting Assemblies now at the same height, install the trim cover by following these steps: 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. The trim covers are sized to fit the AC Module edges and should be positioned to support each location in which the AC Modules will be installed. Ensure that 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. Using the included hardware, attach the endcap plates to both of the open ends of the Trim Cover. Align the holes in the endcap plate with the pre-drilled holes on the ends of the Trim Cover and secure it to each of the...

Leveling the Mounting Assemblies

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. As a starting point, adjust the Mounting Assembly to mid-height where the top of the mounting stud is level with the lower lip of the mount swivel. 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. Once you’ve reached the Mounting Assembly at the other end of the row, 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 1. Note: Apply some tension to the string to create a leveling guide between the first and last Mounting Assemblies. 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 mount swivel to adjust the height so they are the same. To raise the height, turn the mount swivel counterclockwise. To lower the height, turn the mount swivel clockwise. Once the first and last Mounting Assemblies in that row are the same height,...

Mounting Assembly Installation

Mounting Assembly Installation Use the mounting hardware to attach Mounting Assemblies to the Roof Mounts. To begin, only install Mounting Assemblies at the two outer locations in the front row of the array. Each Mounting Assembly has an arrow on the top surface of the 360° swivel that should always point towards the Trim Cover. Secure and tighten each mounting assembly bolt using 14 lb-ft or 19 N-m of torque. The mounting base and swivel portion for each Mounting Assembly should be facing downroof as shown. Note: If you need to adjust the position of the Mounting Assemblies later, you can loosen the mounting bolts and make the necessary...

Roof Mount and Flashing Installation

Roof Mount and Flashing Installation Locate on the roof where the solar array will be installed. Ensure that you adhere to all local rules and regulations that correspond to your location in regards to measurements and spacing from roof eaves and ridges. For tile roof installations, refer to “Appendix B: Tile Roof”. Mark the location of the first row of Roof Mounts by placing a chalk line horizontally across the roof. This chalk line should be 1.5″ (38 mm) up from where the lower edge of the solar array will be installed. Mark the location of the second row of Roof Mounts by placing a parallel chalk line above the first, using the following guidelines: For portrait configurations, mark 66″ (1675 mm) up from the previous chalk line. For landscape configurations, mark 40.13″ (1020 mm) up from the previous chalk line. For additional rows, repeat this step as needed. Mark the center line of each rafter along each of the horizontal chalk lines. These marks should be within 0.25″ (6 mm) of the rafter center line. Identify the first mount location by locating the closest rafter underneath the outside edge of the first AC Module in your array. Mark the center of the first rafter that will support the lower-edge corner of the first AC Module in your array. Ensure the location does not exceed the maximum cantilever distance of 15.75″...

Chapter 5: AC Module Assembly

sunMAX User Guide – Chapter 5: AC Module Assembly The AC Module is a Solar Panel with a Microinverter installed. For ease of installation, assemble the AC Module and attach the required cabling and support clips prior to transferring the AC Module to the roof.   Installing the Microinverter Stand the Solar Panel up against a sturdy wall or lay it on a flat surface that will not scratch the top side of the panel. The pre-installed junction box should be facing you on the upper half of the Solar Panel. Note: Do not sit or place heavy objects anywhere on the Solar Panel. Position the Microinverter into the Solar Panel and slide it up along the edge of the frame until the holes line up at the top. Ensure that the neighboring side of the frame edge sits in the slotted edge of the Microinverter, which secures it to the frame. Connect both cables on the junction box to the DC ports on the Microinverter until you hear them snap in. Each connector is uniquely shaped to prevent reversal during the installation. The Solar Panel will now be referred to as an AC Module.   Installing the Cable Support Clips and Y-Cable Before attaching Cable Support Clips and Y-Cables to the AC Module, decide whether your solar array will be configured for portrait or landscape orientation. Portrait AC Modules...
