About This Cable
This 6mm black solar DC cable is purpose-built for the negative conductor in photovoltaic system wiring. The colour coding — red for positive, black for negative — is the South African solar installation standard that helps with circuit identification, fault-finding, and future maintenance of your system.

How to Order
Add the number of metres you need to your cart. For example, for a 10-metre run, add quantity 10. Cable is supplied as a continuous cut from the roll.
Order Red and Black Together
Solar DC string wiring requires both a positive (red) and negative (black) conductor. Most installations require equal lengths of each colour. Add the same quantity of both the red and black 6mm cables to complete your DC wiring set.





Mariette van den Berg –
Ordered the 6mm Solar PV DC Cable – Black (per metre) along with our panel installation and it arrived promptly with the rest of the system. Quality is noticeably better than local hardware store alternatives. Conductor is consistent and the crimping was clean. Satisfied customer.
Precious Nkosi –
The 6mm Solar PV DC Cable – Black (per metre) was exactly what we needed for our PV installation. Correct sizing, good temperature rating and the UV resistance has held up well after six months outdoors. PowerVault had the best stock availability we found.
