Solar cable extension kit with MC4 connectors, designed for clean and reliable panel wiring in outdoor, marine and off-grid installations. Each kit includes a pair of H1Z2Z2-K 4mm² solar cables with MC4 connectors supplied separately, allowing easier routing through cable glands, bulkheads or smaller drill holes before final assembly.
Unlike fully pre-assembled extensions, these kits give you more freedom during installation:
• pass the cable through tighter openings
• route it through deck glands or conduits more easily
• assemble the MC4 connectors only once the cable is in place
This is especially useful on boats, vans and compact technical installations where access is limited.
This extension set uses H1Z2Z2-K photovoltaic cable, a cable type specifically intended for solar applications. It combines:
• tinned copper conductors for corrosion resistance
• 4mm² section for efficient current transfer
• high flexibility for easier routing
It is suitable for installations exposed to UV, humidity, temperature changes and long-term outdoor use.
These cables are designed for demanding service conditions:
• UV-resistant outer insulation
• double insulation for solar use
• good flexibility even in complex routing paths
• reliable performance in humid or exposed environments
Combined with MC4 connectors, they provide a secure and standardised connection for solar panels, charge controllers and extension runs.
Designed for most low-voltage solar systems:
• 1000V DC / 30A max
• compatible with standard MC4 systems
• suitable for 12V, 24V and 48V solar installations
The 4mm² section offers a good balance between flexibility, compactness and current capacity for small to medium solar systems.
• solar panel extension cable
• routing from panel to charge controller
• boat solar installations
• van / RV solar systems
• off-grid photovoltaic systems
