Step 2: Connecting a PV Module to a Power Optimizer
For mounting on un-grounded structures (such as a wooden structure): If the star washer or
l
the plate cannot be used, use the SolarEdge grounding lug (purchased separately) with an
equipment-grounding conductor a ccording to the supplied instructions. The grounding terminal
accepts a wire size of 6-14 AWG, and must be sized for equipment grounding per NEC 250.122
requirements. Tighten the screws connecting the power optimizer to the frame and the
grounding terminal screw. Apply torque of 9.5 N*m / 7 lb*ft.
5. Verify that each power optimizer is securely attached to the supporting structure or the module.
NOTE
Record power optimizer serial numbers and locations, as described in Providing Installation
Information on page 61.
Step 2: Connecting a PV Module to a Power
Optimizer
For each of the power optimizers
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.
