Suitable for outdoor and rooftop use when installed according to local regulations, it helps connect modules and inverters reliably.

## Long description

Solar PV cable extra digital NV821310 4 mm² on a 400 m spool is a black, cylindrical DC cable intended for photovoltaic systems. It is designed for interconnecting solar panels, creating strings and connecting modules to inverters in medium-power PV installations. The cable features an oxygen-free copper conductor and PVC insulation suitable for outdoor rooftop and ground-mounted applications when installed according to local rules.
Advantages
The conductor is oxygen-free copper (IEC60228 class 5) with low resistance and good conductivity, providing reliable current transfer. The PVC insulation has standard thickness, offers flexibility and mechanical robustness, and is flame retardant and waterproof. The cable is rated for a wide temperature range, resists acids, alkalis and UV exposure, and withstands short-circuit temperatures up to 200°C for short durations. Certified to multiple standards for photovoltaic use.
Suitable for
 DC connections between solar panels
 String wiring in medium-power PV arrays
 Connecting modules to combiner boxes and inverters
 Outdoor rooftop and ground-mounted PV installations (when installed per local regulations)

How to use
Install the cable for DC circuits between PV modules, combiner boxes and inverters, observing polarity and manufacturer instructions. Route and secure the cable to avoid mechanical damage, abrasion and excessive bending; maintain minimum bend radius recommended for flexible copper conductors of the given cross-section. Make connections using appropriate crimp or compression lugs and correct torque values; ensure proper sealing and strain relief at junctions and entry points to prevent water ingress.
Usage recommendations
Use the NV821310 cable for outdoor photovoltaic DC wiring in accordance with local electrical codes and PV installation standards. Verify compatibility with system current and voltage, protect runs with suitable overcurrent devices, and check connectors and terminations are rated for 1500 V and the specified current. Store the spool in a dry, shaded area before installation to preserve the PVC insulation.
