l
If connecting more modules than optimizer inputs in parallel, use a branch cable. Some commercial
power optimizer models have a dual input.
l
Position the power optimizer close enough to its module so that their cables can be connected.
l
Make sure to use power optimizers that have the required output conductor length:
o
Minimize the use of extensions between power optimizers, and use only if connection between
optimizers in different rows or arrays is required.
o
Do not
use extension cables between the modules and the power optimizers.
l
The minimum and maximum string length guidelines are stated in the power optimizer datasheets.
Refer to the SolarEdge Site Designer for string length verification. The SolarEdge Site Designer is
available on the SolarEdge website at

l
Completely shaded modules may cause their power optimizers to temporarily shut down. This will
not affect the performance of the other power optimizers in the string, as long as the minimum
number of unshaded power optimizers connected in a string of modules is met. If under typical
conditions fewer than the minimum optimizers are connected to unshaded modules, add more
optimizers to the string.
l
To allow for heat dissipation, maintain a 2.5 cm / 1" clearance distance between the power optimizer
and other surfaces, on all sides except the mounting bracket side.

Step 1: Mounting the Power Optimizers
For each of the power optimizers

:
1. Determine the power optimizer mounting location and use the power optimizer
mounting brackets to attach the power optimizer to the support structure . It is
recommended to mount the power optimizer in a location protected from direct
sunlight. For frame-mounted power optimizers follow the instructions supplied with
the optimizers, or refer to
