Which products do I need for PV installation?
Typical scope: mounting profiles and roof hooks, module and end clamps, PV cables and MC4 connectors, DC fuses and isolators, surge protection devices, AC distribution boxes as well as battery cables and protection equipment.
-
Which cable cross-section should I use?
Common are 4 mm² and 6 mm² for module strings, 10 mm² for higher currents or longer distances. The decisive factors are current, cable length and permissible voltage drop. Our experts assist with system design.
-
What should be considered with MC4 connectors?
Always use original-compatible MC4, crimp correctly and ensure strain relief and tightness. Avoid mixing different connector types and always connect or disconnect under no load.
-
Which protection components are mandatory?
Recommended: DC fuses per string, DC isolators, surge protection devices on DC and AC sides, as well as correctly sized cables and protective earth conductors. Observe local regulations and manufacturer specifications.
-
Does Offgridtec provide prefabricated cables?
Yes. In our cable workshop we manufacture PV and battery cables in the desired length and cross-section with suitable connectors and terminals. This saves time during installation and increases operational safety.
