     3. Attach each Power Optimizer to the rack using M6 (1/4'') stainless steel bolts, nuts and washers or other mounting hardware. Apply torque of 6.5-7 lb*ft. For 3NA series power optimizes, SolarEdge recommends mounting the Power Optimizer on a rail with the smooth side facing out, so that the Power Optimizer body will prevent its rotation.
  • Page 24 (1) These methods have been evaluated by a nationally recognized testing laboratory as part of the Power Optimizer evaluation. The SolarEdge-supplied grounding lug kit has been evaluated only for use with SolarEdge power optimizers. It is not intended or listed to be used as a general purpose grounding lug with other electrical equipment.
  • Page 25 Figure 5: Power Optimizer installation and grounding using a grounding plate For mounting on un-grounded structures (such as a wooden structure): If the star washer or the plate cannot be used, use the SolarEdge grounding lug (purchased separately) with an equipment-grounding conductor according to the supplied instructions.

  • Page 26: Step 2: Connecting A Pv Module To A Power Optimizer

    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.

  • Page 27: Step 4: Verifying Proper Power Optimizer Connection

     3. Connect the rest of the Power Optimizers in the string in the same manner. Figure 8: Power Optimizers connected in series  4. If you intend to monitor the installation, using the SolarEdge Monitoring platform, record the physical location of each Power Optimizer, as described in Creating Logical and Physical Layout using Installation Information on page 58.
  • Page 28 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. In SolarEdge systems, due to the introduction of Power Optimizers between the PV modules and the inverter, the short circuit current I and the open circuit voltage V hold different meanings from those in traditional systems.
