Installation Guidelines - SolarEdge SE8000H-AU Installation Manual

Installation Guidelines

Frame-mounted power optimizers are mounted directly on the module frame ,
l
regardless of racking system (rail-less or with rails). For installation of frame-mounted
power optimizers, refer to http://www.solaredge.com/sites/default/files/installing_
frame_mounted_power_optimizers.pdf.
The steps in this chapter refer to module add-on power optimizers. For smart
l
modules, start from Step 3: Connecting Power Optimizers in Strings on page 17 . 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. Some commercial
l
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.
o
You can use extension cables between rows and from the end of string to the inverter.
o
Do not use extension cables between the modules and the power optimizers, or between two
o
power optimizers within a string.
The minimum and maximum string length guidelines are stated in the power optimizer datasheets.
l
Refer to the D esigner for string length verification. The D esigner 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.
