3-10 Building Blocks of an Array
6 Building Blocks
•
There are 6 building blocks of AC modules which can be used in building an array. Using the 6
building blocks helps installers sketch array configuration and plan the AC cable connection. The
designer needs to keep in mind that the location of female and male connectors will affect array
design.
•
Each building block has a limitation on the space between two AC modules because of cable
length. Therefore, the space gap between two AC module frames must be kept under the value
specified in each building block.
•
Also, to avoid tensile strain from thermal expansion, it is recommended to leave a space more
than 6 mm (0.236 inches) between AC module frames.
•
This manual provides gap limitation between AC module frames for each building block. After
male and female connection of two AC modules, use cable clips in order to fasten the AC cables
on frames or PV racks.
•
Keep the AC cables off the roof surface or ground.
•
In brief, simple diagrams indicate different types of building blocks describing location of male
and female connectors and gap limitation between AC module frames. So do not interpret the
simple diagrams as the AC cables must make path only to the top direction from an AC module.
•
In cases of portrait in reverse and landscape in common, AC cables run below the microinverter
to meet another AC cable. Keep in mind to fasten the AC cables on frames or PV racks in order
to keep them off of the roof surface.
