Rand PV specializes in <>.

    Combiner boxes save labor and material costs through wire reductions while enhancing overcurrent and overvoltage protection and increasing reliability. This is accomplished by bringing the output of several solar strings together by having each string conductor land on a fuse terminal and the output of the fused inputs are combined onto a single conductor that connects the box to the inverter. You can add disconnect switches, remote rapid shutdown devices, monitoring equipment, and other additional equipment added based on your application needs.

    We will work with you to ensure you have the best <> specific needs and requirements.

    Our linear component design and custom-fabricated enclosures take into consideration wire management, minimization of over-the-air transmission, arc suppression, and safety.

    We work with our customers to create your <> with easy access and egress of lines and cables without bends and tension. As solar panels requirements have evolved all Rand PV’s designs include standard dual polarity fused protection. This is why Rand PV fuses both the positive and negative incoming lines. Our high-current ceramic fuse links with custom-designed holders that are all UL approved for this application, and they come in a variety of amperages.

    NEMA 4X rated enclosures are custom-fabricated using durable UV-resistant poly-coated steel and fully grounded connection between the enclosure door, frame, and back panel with a urethane gasket seal on the enclosure door. The urethan compound is the best choice for a gasket because of its resistance to temperature, moisture, chemicals, and compression set.

    Every <> has the following safety features:

    • The DC disconnect switch is manufactured with a patented design with arc-extinguishing chamber.
    • The switch has a deeper mounting base keeping the suspended cables further away from the back plate which is a concern for electrical arcing.
    • The enclosure is fully grounded to the frame.
    • Both the positive and negative lines are routed through the surge protection block.
    • An acrylic electrical arc shield is installed in front of the bus bars, wire, and connectors.

    We are able to customize wall mounts, free-standing modular models, junction terminals, operator interfaces, PLC’s, meters, controls, switches, server racks, for indoor or outdoor unique applications.

    Whether your combiner boxes are for battery storage, solar utility energy, IT, climate control, medical facilities, data centers, telecommunications, computing or computer storage, alternative energy, EV charging, game room equipment, wind turbines, manufacturing, building, or construction, we will ensure your <> is the perfect solution for your unique end application.

    We are able to manufacture all combiners according to ISO 14001, ISO 45001, ISO 9001, NABCEP, NRTL, UL 1703, UL 1741, all UL approved and listed certifications, IP55, IP56, IP65, IP66, and IP67 certifications.
