3. If you intend to monitor the installation, using the monitoring platform, record the
physical location of each power optimizer, as described in Creating Logical and
Physical Layout using Installation Information on page 44.

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.
In SolarEdge systems, due to the introduction of power optimizers between the PV
modules and the inverter, the short circuit current I
hold different meanings from those in traditional systems.

current, refer to the V
