Step 2: Connecting a PV Module to a Power Optimizer
NOTE
Images are for illustration purposes only. Refer to the label on the product to
identify the plus and minus input and output connectors.
For each of the power optimizers:
Connect the Plus (+) output connector of the module to the Plus (+) input
connector of the power optimizer.
Connect the Minus (-) output connector of the module to the Minus (-) input
connector of the power optimizer.

Step 3: Connecting Power Optimizers in Strings
You can construct parallel strings of unequal length, that is, the number of power
optimizers in each string does not have to be the same. The minimum and maximum
string lengths are specified in the power datasheets. Refer to the SolarEdge Site
Designer for string length verification.
NOTE
Use at least 11 AWG/ 4 mm² DC cables.
The total conductor length of the string (excluding power optimizers’
conductors; including home runs and necessary extensions between
optimizers) should not exceed:
For inverter models SE14.4K and SE33.3K - 2300 ft./ 700 m from DC+
to DC- of the inverter
