Installation Guide

IMPORTANTSAFETYFEATURE
For a compliant PVRapid Shutdown (PVRSS) installation, use no more
than 30 optimizers per string.
Enabling PVRSS from the inverter menu is only required if the installed
optimizers were manufactured before 2015, otherwise it is enabled by
default.
NOTE
The DC bus of each unit is separate and not shared for all units. Therefore in
addition to following the inverter design rules, each unit should follow the
unit design rules as detailed in the Technical Specifications.
1. Connect the Minus (-) output connector of the string’s first power optimizer to the
Plus (+) output connector of the string’s second power optimizer.
2.
Connect the rest of the power optimizers in the string in the same manner.

If you intend to monitor the installation, using the SolarEdge monitoring platform,
record the physical location of each power optimizer, as described in Creating
Logical and Physical Layout using Installation Information on page 66.
Step 4: Verifying Proper Power Optimizer Connection
When a module is connected to a power optimizer, the power optimizer outputs a safe
voltage of 1V (±0.1V). Therefore, the total string voltage should equal 1V times the
number of power optimizers connected in series in the string. For example, if 10 power
optimizers are connected in a string, then 10V should be produced.
Make sure the PVmodules are exposed to sunlight during this process. The power
optimizer will only turn ON if the PVmodule provides at least 2W.
