5m single core extension cable (4.0mm) with MC4 connectors

This cable is a single core solar extension cable with a 4.0mm cross section. It is specially designed for solar panels to carry high current with minimal power loss. The cable comes with waterproof MC4 connectors - "male" on one end and "female" on the other end. These connectors can be easily connected to similar MC4-type connectors that come with most solar panels, including Photonic Universe solar panels.

The cable is suitable for all weather conditions, including cold and hot temperatures. The 4.0mm cross section is typically enough for off-grid 12V solar panels and systems up to 160W, or on-grid panels with a typical voltage of 30-60V and a higher power rating. If needed, the cable can be cut in half to make two 2.5m tails. Here are the cable specifications: 

- Conductor: tinned copper 

- Cross section: 4.0mm 

- Conductor resistance: 5.09 Ohm/km (at 20°C) 

- Insulation and Jacket: 120°C XLPE 

- Working temperature range: -40°C to +120C 

- Certification: TUV 

- Outer diameter: 6.1mm
