Step 2: Connecting A Pv Module To A Power Optimizer; Step 3: Connecting Power Optimizers In Strings - SolarEdge SE3000H-US Installation Manual

6. Record power optimizer serial numbers and locations, as described in Reporting and Monitoring
Installation Data on page 35.
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 poweroptimizers:
Connect the Plus (+) output connector of the module to the Plus (+) input connector of the power
l
optimizer.
Connect the Minus (-) output connector of the module to the Minus (-) input connector of the
l
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 optimizer datasheets. Refer to the Designer for
string length verification.
NOTE
Use at least 11 AWG/ 4 mm² DC cables.
l
The total cable length of the string (excluding power optimizers' cables) s hould not exceed
l
1000ft./300 m from DC+ to DC- of the inverter.
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.
