Installation Guidelines; Step 1, Mounting The Power Optimizers - SolarEdge Solar Inverter Installation Manual

Chapter 2: Installing the Power Optimizers

Installation Guidelines


This chapter refers only to the module add-on power optimizers. For module-embedded models,
refer to the installations instructions supplied with the embedded module.

The power optimizer can be placed in any orientation.

Position the power optimizer close enough to its module so that their cables can be connected.

To allow proper heat dissipation, maintain a 1" /2.5 cm clearance distance between the power
optimizer and other surfaces.

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 http://www.solaredge.com/groups/support/downloads, under
Software Tools.

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
numbers of power optimizers are connected in a string to modules. 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 uncovered. Open connectors should be mated to each
other.

Step 1, Mounting 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 1).
2
If required, mark the mounting holes locations and drill the holes.
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.
3
Attach each power optimizer to the rack using the M6 (1/4'') or M8 (5/16") stainless steel bolts, nuts
and washers.
4
Verify that each power optimizer is securely attached to the supporting structure or the module.
NOTE:
Record power optimizer serial numbers and locations, as described in Providing Installation
Information on page 27.
