PV-Ultra® 4mm² 4 Core Double Insulated Multicore DC Cable | PV-ULTRA4C4.0

PV-Ultra® 4mm² 4 Core Double Insulated Multicore DC Cable is purpose-designed for photovoltaic (solar PV) DC installations, providing a safe, compliant and durable solution for DC interconnections between solar panels, DC isolators and inverters.

Please Note: PV-Ultra® Cable is sold per meter 

Developed specifically for the DC side of PV systems, PV-Ultra® replaces older multicore armoured approaches that are no longer recommended. With double insulated conductors, high mechanical strength and UV-stable outer sheath, it is suitable for both internal and external installation and is engineered for a service life of around 25 years.
