Your Installation Accessories for Photovoltaic and Solar Systems

At Offgridtec, you’ll find the right installation accessories for every photovoltaic Project - from small balcony systems to large rooftop installations: mounting and installation on roofs, facades, or open spaces; electrical installations for DC and AC; and pre-assembled and loose solar cables from our in-house cable manufacturing facility. All components are designed to work together and are ready for immediate use.

Mounting and Installation

For mounting and installing your solar modules, we offer mounting profiles, rail connectors, roof hooks, clamps, and screw sets. Whether you have a tile, metal, or flat roof, or are setting up a freestanding or mobile system: With our mounting kits, you can tackle your PV installation quickly and safely.

Electrical Installation

For the electrical installation of your PV system, DC fuses, fuse holders, DC load break switches, surge protection, and AC distribution panels ensure a safe connection. We also provide measurement and protection equipment, switch panels, and timers.

Wiring and Connection

For wiring and connecting your solar system, you’ll find solar cables such as the H1Z2Z2-K, pre-assembled PV connection cables, extension cords, Y-adapters, MC4 connectors and couplers, cable glands, and cable bushings. We manufacture many of these cables in our own cable factory, custom-made to your exact length and cross-section.

• PV Cables and Solar Cables: 4 mm², 6 mm², 10 mm²
• MC4 connectors, branch connectors, crimping pliers, and tools
• Battery cables, ring terminals, pole clamps, and main switches

Connection Technology

In our connection technology section, you’ll find solar connectors, plug-in connectors, and adapters for virtually any application: MC4 and Stäubli connectors, branch sockets as Y- and T-connectors, SJ50 connectors (Anderson-compatible), Wieland circular connectors, as well as flush-mount receptacles and switches. These allow you to securely and detachably connect modules, cables, and loads.

Adhesives and Sealants

Our adhesives and sealants provide a permanently elastic and UV-resistant seal and bond for your mounting Points - for example, Dekalin’s MS polymer high-strength adhesives, available as single cartridges or as a convenient adhesive set that includes a Dekavator and cleaning cloth. This allows you to reliably seal cable entries, mounts, and attachments.

Accessories for Solar Modules, Electronics, and Batteries

Our solar module accessories include mounts, cable channels, protective tubes, and gaskets for neat cable routing. Our electronics accessories complement inverters and charge controllers, and our battery accessories include battery monitoring systems, disconnect switches, and compatible fuses. This helps you get the maximum performance and service life out of your system.

Miscellaneous Installation Accessories

Under “Miscellaneous,” you’ll find practical tools to help with your installation: cable ties and Velcro cable ties for neat cable management, PV cable clamps, outlet-mounted electricity meters for balcony power plants, surge protection adapters, and temperature sensors. Small parts with a big impact on your day-to-day use of your solar system.

Frequently Asked Questions About PV Installation

• What products do I need for a PV installation?

  Typical components: mounting profiles and roof hooks, module and terminal clamps, solar cables and MC4 connectors, connectors and adapters, DC fuses and load break switches, surge protection, adhesives and sealants, as well as battery cables and protective equipment.

• What cable gauge should I use?

  4 mm² and 6 mm² are standard for module strings; 10 mm² is used for higher currents or longer distances. The key factors are current, cable length, and permissible voltage drop. Our team will be happy to help you with the design.

• What should I keep in mind with MC4 connectors?

  Use only original-compatible MC4 connectors, crimp them correctly, and ensure proper strain relief and a tight seal. Avoid mixing different types of connectors, and always connect or disconnect them only when the system is de-energized.

• Which protective components are required?

  We recommend DC fuses for each circuit, DC load break switches, overvoltage protection for both DC and AC, as well as properly sized cables and protective conductors. Follow local standards and manufacturer specifications.

• Does Offgridtec offer pre-assembled cables?

  Yes. In our cable manufacturing facility, we produce PV and battery cables in the desired length and cross-section with matching connectors and cable lugs. This saves you time during installation and increases operational safety.

• What is the difference between “Wiring & Connecting” and “Connection Technology”?

  In the “Wiring & Connecting ” section, you’ll find the cables themselves; in the “Connection Technology” section, you’ll find the matching plugs, sockets, and adapters.
