Installation Procedures
APsystems Microinverters are designed to only operate when they can sense power coming
from the grid. Even if they are plugged into the solar array, they will not turn themselves on
until they can read power from the grid.
Do NOT connect APsystems Microinverters to the utility grid or energize the AC circuit
until you have completed all of the installation procedures as described in the following
sections.
Step 1 - Lay the AC bus according to the arrangement of APsystems
Microinverter
Step 2 - Attaching the APsystems Microinverters to the Racking
Figure 2
a. Mark the location of the Microinverter on the rack, with respect to the PV module
junction box or any other obstructions.
b. Mount one Microinverter at each of these locations using hardware recommended by
your module racking vendor.
Prior to installing any of the microinverters, verify that the utility voltage at the point of
common connection matches the voltage rating on microinverter label.
Do not place the inverters (including DC and AC connectors)Where exposed to the sun,
rain or snow, even gap between modules. Allow a minimum of 3/4’’(1.5cm.) between
the roof and the bottom of the Microinverter to allow proper air flow.
