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 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.
