Mounting the SMI

This chapter describes how to mount the SMI. At this stage, power optimizers are 

already installed and connected in strings. For more information on power optimizer 

installation, refer to the IndOP™ power optimizers installation guide available on the 

SolarEdge website at 

http://www.solaredge.com/files/pdfs/products/power-optimizers/se_

power_optimizers_installation_guide_indop.pdf

.

The SMI can be mounted either vertically or horizontally. Each of these installation 

options is described below. The SMI is supplied with two brackets pre-assembled for 

vertical mounting. When choosing the horizontal mounting option, remove these 

brackets and use the four floor anchoring brackets supplied in the package.

To Mount the SMI vertically:

 1.  Determine the SMI mounting location, on a wall or pole, as follows:

To allow proper heat dissipation, maintain 2'' / 5 cm minimum clearance areas 

between the SMI and other objects.

Make sure the mounting surface or structure can support the weight of the SMI.

 2.  Position the mounting bracket against the wall and mark the drilling hole locations. 

Ensure that the flat side of the bracket is at the bottom.

Figure 6: Wall mounting bracket

 3.  Use at least two bracket holes. Additional holes can be used to fix the 

bracket.Determine which and how many holes to use according to mounting 

surface type and material.

 4.  Drill the holes and mount the bracket. Verify that the bracket is firmly attached to 

the mounting surface.

 5.  Hang the SMI on the bracket: Align the two assembled brackets on the SMI 

enclosure with the two triangular protrusions of the mounting bracket, and lower 

the SMI until it rests on the bracket.
