Pair of 30-foot red and black 12AWG solar cables with waterproof connectors

BFKK

BFKK 30 Feet 12AWG Solar Extension Cable Kit

SKU CH-7Q4Q-SG2RY

A 30-foot 12AWG solar extension cable pair with IP68 waterproof connectors rated for 57A and temperatures from -40°C to 90°C

Cable Length 30 Feet

  • 30 ft reach connects distant panels to controllers
  • 12 AWG tin-plated copper cuts resistive loss
  • IP68 waterproof rating survives decades outdoors
  • TÜV / CE certified for 57 A continuous duty
  • 40 °C to 90 °C operation handles extreme climates

Solar Extension Cable Kit

The BFKK 30 Feet 12AWG Solar Extension Cable Kit provides a pre-terminated pair of photovoltaic cables for linking panels to charge controllers in off-grid and RV installations. Each kit includes one red and one black lead fitted with locking male and female connectors that snap together for secure, tool-free daisy-chaining. The tin-plated copper conductors and PPO flame-retardant jacketing are rated for direct burial and decades of outdoor exposure.

12AWG Capacity and 57A Rating

At 4 mm² cross-section the 12AWG conductors carry a rated 57 A, giving ample headroom for typical residential and mobile arrays while keeping voltage drop low over the 30-foot run. Conductor resistance is 5.09 Ω/km at 20 °C, so losses remain modest on shorter strings but will become noticeable on very long parallel runs or high-current configurations. The cable is certified to 6500 V test voltage, ensuring insulation integrity under normal system voltages.

IP68 Weatherproofing and Thermal Range

Connectors meet IP68 waterproofing, and the jacket withstands continuous ambient temperatures from -40 °C to 90 °C (-40 °F to 194 °F) plus UV, moisture and corrosion resistance. No active cooling is required; the assembly runs passively and silently in normal operation. Power draw is determined solely by the connected array, with the cable itself adding negligible loss within its rated current envelope.

Questions about this item

Will the 12AWG cable handle the 57 A rated current from my existing charge controller without overheating?

Yes, the 12AWG tin-plated copper conductors are rated for 57 A at 20 °C with a resistance of 5.09 Ω/km, keeping voltage drop low on a 30-foot run.

How can I verify the IP68 waterproof seal is intact after connecting the male and female connectors?

Engage the self-locking mechanism until it clicks; the mated pair is then rated IP68 for continuous outdoor exposure and direct burial.

Does the kit include both the red and black 30-foot cables with pre-attached MC4-compatible connectors, or must I crimp my own?

The kit supplies one red and one black 30-foot 12AWG cable, each terminated with factory-fitted male and female waterproof connectors ready to plug in.
