SolarEdge SE5000H-AU Installation Manual page 19

Frame-mounted power optimisers are mounted directly on the panel
frame, regardless of racking system (rail-less or with rails). For
installation of frame-mounted power optimisers, refer to
http://www.solaredge.com/sites/default/files/installing_frame_
mounted_power_optimizers.pdf.
The steps in this chapter refer to panel add-on power optimisers. For smart panels,
start from Step 2: Connecting Power Optimisers in Strings on page 20 .Also refer to
the documentation supplied with the smart panels.
The power optimiser can be placed in any orientation.
If connecting more panels than optimiser inputs in parallel, use a branch cable.
Some commercial power optimiser panels have a dual input.
Position the power optimiser close enough to its panel so that their cables can be
connected.
Make sure to use power optimisers that have the required output conductor length:
Do not use extension cables between a panel and a power optimiser, between
two panels connected to the same optimiser, or between two optimisers other
than in the cases specified below.
You can use extension cables between power optimisers only from row to row,
around obstacles or pathways within a row, and from the end of the string to
the inverter, as long as the maximum distance is not exceeded.
NOTE
Use at least 11 AWG/ 4 mm² DC cables.
The total cable length of the string (excluding power optimisers'
cables) should not exceed 300 m from DC+ to DC- of the inverter.
Completely shaded panels may cause their power optimisers to temporarily shut
down. This will not affect the performance of the other power optimisers in the
string, as long as the minimum number of unshaded power optimisers connected in
a string of panels is met. If under typical conditions fewer than the minimum
optimisers are connected to unshaded panels, add more optimisers to the string.
To allow for heat dissipation, maintain a minimum of 2.5 cm clearance between the
power optimiser and other surfaces, on all sides except the mounting bracket side.
