PV ConnectorsPV connectors are used to connect the end of each array of panels to the PV wire that runs back to the combiner box.Note: Not all PV connectors mate together. It is critical that you know the manufacturer of the connector that is on theend of the array of panels.Combiner BoxesSolar combiner boxes are used to combine PV cables from several solar arrays. The PV cables are fed through fusesto produce a single output that is then fed to the inverter. Combiner boxes are used for both commercial rooftopand solar farm applications.• 600 V or 1 kV• Input circuits: 1–48 circuits• UL 1741 standard• Enclosure types, NEMA 4X fiberglass or NEMA 3R painted steel• Fuses: fused or nonfused• Monitoring: wireless monitoring, wired monitoring, unmonitored• Integral disconnect: with or without disconnect switchFusesFuses for combiner boxes can be included with the combiner box or may be purchased separately.600 V• Fast-acting fuses• 8 A, 10 A, 12 A and 15 A (most common)1,000 V• PV fuses• 8 A, 10 A, 12 A and 15 A (most common)GroundingAnixter has a wide variety of product available to help you with your grounding requirements.• Copper ground rods• Mechanical and compression grounding connectors• Flexible braid• Lightning arrestors• Exothermic groundingPower ConnectorsCopper and aluminum compression connectors are used for terminating medium and large AWG size cablesin electrical applications.• Compression type lugs• Compression barrel splices• Mechanical lugs and splices
Physical Support ProductsPhotovoltaic installations (whether rooftop or utility scale) are subject to adverse UV light, wind and corrosive conditions. Anixter offers a full line of physical support products to help protect,route and support solar installations of any type. Our product portfolio includes cable tray, conduit, cable ties and clips, roof blocks, and other innovative routing and mounting solutions.Cable Tray• Supports and routes cable• Available in several materials (e.g., aluminum, galvanized steel and stainless steel)• Ladder tray or basket trayConduit• Conduit fittings and connectors• Routes and protects cable• Flexible or rigid• Metallic or nonmetallicRoof Blocks• Made from recycled rubber• No roof penetration required• Customizable to support conduit, tray, duct, walkway or framePanel Racking SolutionsPanel racks are used to support, mount and ground solar installations. Anixter can supply several racking solutions, including innovativeproducts that are lightweight, yet strong, and also serve as a system that routes and protects the PV cabling.UV Stabilized Cable Ties and Edge ClipsSpecifically designed for the solar industry, Anixter offers cable ties and edge clips that are made of UV stabilized PA66UV material.This provides additional protection against UV radiation for long-term outdoor use.Cable TiesUV stabilized cable ties are available in a wide range of styles, tensile strengths and bundle diameters.Edge ClipsUV stabilized edge clips are designed to route cable by securing them to a metal or plastic frame rail edge, which eliminatesthe need for mounting holes or mechanical fasteners.

This can strings in parallel, eliminating the need be especially valuable to a contractor to run a positive and negative from each working on a large job with cable reels string back to the combiner box. scattered throughout a lay-down area.• Jumpers can be used to connect the end of an array to a parallel wiring assembly.• Pigtails are useful in wiring the end panel of an array to the combiner box.
CASE STUDY | Anixter Helps Contractor on Solar Farm Project Meet Deadline and Reduce Costs Challenge A contractor working on the construction of a new solar farm needed to complete the project within seven months while staying on budget. With such time and cost restrictions, coupled with the limited on-site storage space, the contractor didn’t want to worry about the material management aspect of the job. The contractor wanted to spend its time getting the project up and running by the deadline instead of poring over cable specifications, managing multiple manufacturers and building out a bill of materials. If it could streamline to procurement, delivery and management of materials, the contractor could better focus on its core competencies and control costs. Anixter’s Solution: READY!SM To Install To help the contractor address its deadline and budget challenges, Anixter assumed control of the procurement and management of products for the solar farm construction, including 15 kV and 2 kV power cable, 12- and 24-fiber cable, bare copper cable, lugs and conduit. After procuring the products and consolidating them at a local distribution center, Anixter used its READY! To Install material management solution to cut the cable to customer-specific lengths and place them on multicompartment Parapull reels. Each reel was clearly labeled with the circuit ID and power station number as specified by the customer. The cables and accompanying products were then deployed per power station: two power stations per release with five releases over the project duration. In addition, Anixter recycled the empty reels to eliminate labor and disposal costs. Benefits • Deployed project on time and on budget • Eliminated challenges of in-field terminations • Simplified material management and deployment at the job site • Improved contractor’s efficiency • Reduced material scrap, excess and obsolete inventory • Integrated into contractor’s schedule/process • Single part number specification and ordering • Complemented contractor’s core competency TO INSTALL Our Manufacturer Partners Anixter partners with best-in-class manufacturers to provide you with the products and technologies you need.
