At Offgridtec, you will find installation accessories for projects of all sizes: fastening and mounting on roofs, facades, or open spaces, electrical installation accessories for DC and AC, as well as pre-assembled and loose PV cables from our own factory. All components are compatible with each other and ready for immediate use.
Electrical installation
Everything you need for the safe connection of PV systems: DC fuses and holders, DC load break switches, surge protection, AC distributors, measurement and protection technology. We also offer battery chargers, charge boosters, and accessories for inverters and voltage converters.
Cabling and connection
PV cables (e.g., H1Z2Z2-K), pre-assembled connection cables, extensions, Y-adapters, MC4 plugs and couplings, cable glands, and cable bushings. We manufacture many cables in our own cable factory, precisely tailored to the required length and cross-section.
- PV cables: 4 mm², 6 mm², 10 mm²
- MC4 connectors, branch connectors, crimping pliers, and tools
- Battery cables, ring cable lugs, pole terminals, and main switches
Fastening and mounting
Mounting profiles, rail connectors, roof hooks, clamps, and screw sets for modules. Solutions for tile, sheet metal, and flat roofs, as well as for outdoor installation and mobile applications. Fully coordinated kits speed up installation and increase operational safety.
Accessories for modules, electronics, and batteries
Brackets, cable ducts, protective tubes, and seals for clean cable routing. Electronic accessories for inverters and charge controllers, battery accessories such as monitoring, disconnect switches, and fuses. This allows you to get maximum performance and service life from your system.

-
What products do I need for the PV installation?
Typical scope: mounting profiles and roof hooks, module and end clamps, PV cables and MC4 connectors, DC fuses and load break switches, surge protection, AC distributors, battery cables, and protection technology.
-
What cable cross-section should I use?
4 mm² and 6 mm² are common for module strings, 10 mm² for higher currents or longer distances. The decisive factors are current strength, cable length, and permissible voltage drop. Our experts will help you with the design.
-
What should be considered with MC4 connectors?
Only use original compatible MC4 connectors, crimp correctly, and ensure strain relief and tightness. Avoid mixed configurations and always connect or disconnect connectors without voltage.
-
Which protective components are mandatory?
We recommend DC fuses per string, DC load break switches, overvoltage protection on DC and AC, and correctly dimensioned cables and protective conductors. Observe local standards and manufacturer specifications.
-
Does Offgridtec offer pre-assembled cables?
Yes. In our cable factory, we manufacture PV and battery cables in the desired length and cross-section with matching plugs and cable lugs. This saves time during installation and increases operational safety.
