of one Power Optimizer to the long Plus (+) output connector of the next Power
Optimizer.
2. To minimize electromagnetic interference (EMI), make sure to minimize the distance
between the positive and negative DC cables.
For detailed instructions, see:

performance-application-note.pdf.
3. Connect the rest of the power optimizers in the string in the same manner.
WARNING!
If using a dual-input power optimizer and some inputs are not used, seal the
unused input connectors with the supplied pair of seals.
AVERTISSEMENT!
Si un optimiseur à double entrées est utilisé et que certaines entrées ne sont
pas connectées, fermez ces entrées avec la paire de couvercles fournie.
4. 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 58.

Step 4: Verifying Proper Power Optimizer Connection

When a panel is connected to a Power Optimizer, the Power Optimizer outputs a safe
voltage of 1V (±0.1V). Therefore, the total PV string voltage should equal 1V times the
number of Power Optimizers connected in series in the PV string. For example, if 10
Power Optimizers are connected in a PV string, then 10V should be produced.
Make sure the PV panels are exposed to sunlight during this process. The Power
Optimizer will only turn ON if the PV panel provides at least 2W.
In SolarEdge systems, due to the introduction of Power Optimizers between the PV
panels and the inverter, the short circuit current I
hold different meanings from those in traditional systems.
