BFKK

BFKK 30 Feet 10AWG Solar Extension Cable Kit

SKU CH-0JRA-SEBA6

30-foot 10AWG solar extension pair with IP68 waterproof connectors, rated 57A and 6500V for PV systems

Cable Length 30 Feet

  • Tin-plated copper conductors cut resistance to 5.09 Ω/km for efficient power transfer
  • TÜV and CE certified cable rated for 57 A continuous current
  • IP68 waterproof connectors lock securely for reliable outdoor connections
  • PPO flame-retardant jacket withstands -40 °C to 90 °C ambient extremes
  • 30 ft 10 AWG pair connects panels to charge controllers in RV and PV systems

Solar Extension Cable Kit

The BFKK 30 Feet 10AWG kit provides a paired black and red cable set with pre-fitted male and female waterproof connectors. It is designed for installers who need a ready-made link between photovoltaic modules and a charge controller in RV or fixed-array systems.

Build integration

Each lead terminates in a self-locking PV connector so multiple kits can be chained together for longer runs without tools. The 10AWG tin-plated copper conductors reduce resistive loss, leaving more harvested energy for the battery bank while the IP68 rating means the joints survive permanent outdoor exposure.

Thermals and power

The 6 mm² cross-section is rated for 57 A continuous current and has a conductor resistance of 5.09 Ω/km at 20 °C. Insulation withstands an operating range of -40 °C to 90 °C (-40 °F to 194 °F) and passes a 6500 V dielectric test, so the cables run cool and safe under normal array voltages.

Questions about this item

How much current can the 10AWG cable carry before it becomes the limiting factor under sustained use?

The cable is rated for 57A continuous current, so that is the ceiling before the wire itself limits the system.

What temperature range can the cable and connectors withstand when running all day in direct sun?

The cable operates from -40°C to 90°C and the connectors share the same -40°C to 90°C rating, with IP68 waterproofing for long outdoor exposure.

Which connectors must already be on the solar panel and charge controller for this kit to plug straight in?

The kit uses standard MC4-compatible male and female connectors, so both the panel and controller need matching MC4 ports.
