Step 1: Mounting The Power Optimizers - SolarEdge SE50K Installation Manual

Step 1: Mounting the Power Optimizers

The steps in this chapter refer to module add-on power optimizers. For smart modules, start from
l
Step 3: Connecting Power Optimizers in Strings on page 15 . Also refer to the documentation supplied
with the smart modules.
The power optimizer can be placed in any orientation.
l
If connecting more modules than optimizer inputs in parallel, use a branch cable (available from
l
SolarEdge). Some commercial power optimizer models h ave a dual input .
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:
l
Minimize the use of extensions between power optimizers, and use only if connection between
o
optimizers in different rows or arrays is required.
Do not use extension cables between the modules and the power optimizers.
o
The minimum and maximum string length guidelines are stated in the power optimizer datasheets.
l
Refer to the SolarEdge Site Designer for string length verification. The SolarEdge Site Designer is
available on the SolarEdge website at http://www.solaredge.com/products/installer-tools/site-
designer#/.
Completely shaded modules may cause their power optimizers to temporarily shut down. This will
l
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.
T o allow for heat dissipation, maintain a 2.5 cm / 1" clearance distance between the power optimizer
l
and other surfaces, on all sides except the mounting bracket side.

The images contained herein are for illustrative purposes only and may vary depending on product
models.
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 . For
frame-mounted power optimizers follow the instructions supplied with the
optimizers, or refer to https://www.solaredge.com/sites/default/files/installing_
frame_mounted_power_optimizers.pdf.
