8 Mounting the Power Optimizers Determine the mounting location of each power optimizer Attach the Optimizer to the racking in close proximity to the PV Module location The Power Optimizer can be installed in any orientation At least 1 between the and roof, optimizer and PV Module Do not leave unmated Optimizer connectors exposed to the elements. The Power Optimizer is waterproof when the input and output cable connectors are mated. 8

9 Mounting the Power Optimizers Use 1/4 or 5/16 mounting hardware, appropriate for the racking rail, verify secure attachment. Use both mounting holes to attach each power optimizer to the racking Install the 5/16 stainless steel star washer included with the optimizer behind the flat mounting tab surface Mounting Hole Star Washer 9

10 Grounding the Power Optimizers SolarEdge Power Optimizers only require equipment grounding Equipment grounding of the power optimizers can be accomplished using one of two methods as outlined in the SolarEdge installation manual. 1. Mounting to grounded racking where the star washer contacts the rail Use the 5/16'' stainless steel grounding star washer Star Washer (provided with the power optimizer) between the rail and the flat side of the mounting bracket Unirac Solarmount IronRidge XRL, XRS More examples in the Grounding SolarEdge Optimizers app note 10

11 Grounding the Power Optimizers 2. Mounting on rails with sliding nut fasteners or non metallic structures A separate Equipment Grounding Conductor is required for power optimizers mounted on non metallic structures and structures utilizing sliding nut fasteners (ground lugs may be purchased in bulk from SolarEdge, part number SE GNDLUG 100) ProSolar SnapNrack More examples in the Grounding SolarEdge Optimizers app note Attachment of the grounding lug 11

Connecting Optimizers in Strings Connect the Plus (+) connector of the output wire of the first power optimizer in the string to the Minus ( ) connector of the second power optimizer in the string.

12 Connecting Optimizers in Strings Connect the Plus (+) connector of the output wire of the first power optimizer in the string to the Minus ( ) connector of the second power optimizer in the string. Repeat for each power optimizer in the string. Verify Plus (+) and Minus ( ) connector cables are firmly inserted. Cutting the power optimizer s input or output cable connectors is prohibited, and will void its warranty. Fasten any excess wire to the racking with tie wraps or cable clips 12

13 Array Home Runs Combining Strings at the array No fusing required if 2 strings or less Running individual strings to the inverter allows for troubleshooting at ground level Conduits Metal conduit required whenever DC wiring enters a building Flexible metal conduit or liquidtight conduit allowed Wire Types All exposed PV wire must be double insulated PV wire Installers typically transition from PV wire to building wire (THWN 2 or similar) and conduit for the run from the roof to the inverter 13

19 Connecting the PV Modules Connect each PV Module to power optimizer inputs As long as the optimizers are not connected to the inverter or the inverter is OFF, the optimizers will output a 1 Vdc safe voltage. Note: The power optimizer has reverse polarity protection. Even so, verify the correct polarity by checking the PV module s polarity with a voltmeter. 19

20 Safe Voltage Verification Connect a voltmeter with at least 0.1V measurement accuracy to the string outputs and verify: The voltage equals the number of power optimizers in the string Verify each string individually before proceeding SafeDC Voltage Correct polarity Note: modules should be exposed to sunlight during verification 20
