Having Doubts? Our FAQ

What cable sizes are compatible with Frigate’s MC4 connector assemblies?

Our assemblies are fully compatible with industry-standard solar DC cables, accommodating cross-sections of 2.5 mm ², 4.0 mm ², and 6.0 mm ² (14, 12, and 10 AWG), allowing for seamless integration into diverse project layouts.

Are these connectors compatible with third-party MC4 brands?

Yes, they are engineered to intermate reliably with standard MC4-style connectors according to IEC 62852. However, for maximum efficiency and to ensure complete IP68 protection.

How do these assemblies hold up against severe outdoor weather conditions?

Frigate assemblies are constructed using UV-stabilized, UL94-V0 flame-retardant polycarbonate materials and premium internal seals. They carry an IP68 rating, meaning they are completely dust-tight and resistant to continuous water immersion.

Can Frigate customize the lead wire length and configuration?

Absolutely. We can provide tailored wire lengths, specialized wire types (such as electron-beam cross-linked solar cables), and pre-terminated harness configurations based on your design blueprints.

What certifications do your solar connector assemblies carry?

Our products are manufactured in compliance with international performance and safety benchmarks, adhering closely to TÜV Rheinland (IEC 62852) and UL 6703 standard guidelines for photovoltaic systems.
