Installation Guidelines

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
Position the power optimizer close enough to its module so that their cables can be connected.
l
To allow for heat dissipation, maintain a 2.5 cm/ 1" clearance distance between the power optimizer
l
and other surfaces.
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
l
available on the SolarEdge website at http://www.solaredge.us/groups/support/downloads, under
Software Tools.
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.
Do not leave the power optimizers connectors disconnected. Open connectors should be mated to
l
each other.
Equipment grounding tightening torques: 4-6 AWG: 45 lb-in, 8 AWG: 4 0 lb-in, 10-14 AWG: 35 lb-in.

Step 1: Mounting and Grounding 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 (See Figure 2). For frame-mounted power
optimizers follow the instructions supplied with the optimizers.
2. If required, mark the mounting hole locations and drill the hole.
CAUTION!
Do not drill through the power optimizer or through the mounting holes. The drilling vibrations can
damage the power optimizer and will void the warranty.
Ne pas percer à travers la optimiseur de puissance ou ses trous de fixation. Les vibrations qui en
résulteraient peuvent endommager la optimiseur de puissance.
