Module Installation
This section describes how to lay down and interconnect AC modules on a previously installed
mounting system. No attempt is made to describe how to install the mounting system on the
roof or how to use module clamps.
Before installing the mounting system, ensure that mounting rails will be positioned below the
microinverter once the module is installed. The microinverter extends beyond the edge of the
frame of most modules. Do not install modules with the microinverter resting on the mounting
rail.
The frame of the installed module must rest firmly on the mounting rail.
Installing a module with the microinverter resting on the rail and uneven
contact between the frame and the rail can cause damage to the
microinverter and the module.
The metal components of the AC module, including frame and
microinverter, can reach temperatures of approximately 80
℃
. To reduce
risk of burns, use appropriate safety procedures when handling.
Installing the Modules
The ideal installation path is to begin closest to the installed transition box and plug in each
module as you move away from the box. Depending on the configuration of your array and the
location of the transition box, this path may not be feasible. For example, in a 2-row
configuration, we recommend installing the bottom row first and working up toward the
transition box, which is likely mounted higher up the roof.
The following diagram shows two installed modules as viewed from the bottom or underside of
the module.
