DC Cable 4mm & 6mm in Red & Black | High Quality Solar & Electrical Wire

Solar DC cable is one of the most important parts of a rooftop or ground-mounted PV system because it carries the panel-side DC current between solar modules, combiner points, isolators and the inverter. On the live CNC Electric Pakistan page, this product is sold as a 100 meter solar DC cable in red and black, with 4mm and 6mm selector options, and the page currently displays Rs.20,000. For buyers in Pakistan, this is the cable category used where ordinary house wire is the wrong choice and proper PV-grade insulation, sunlight resistance and outdoor life matter.

The common mistake is to buy good panels and inverter, then cut cost on cable. That is where voltage drop, heating and early insulation trouble begin. In Lahore, Faisalabad and Karachi, rooftop exposure is hard enough that proper PV cable matters.

Applications — Where to Use This Solar DC Cable

This cable belongs on the DC side of a solar installation. That means panel strings, combiner entry, DC isolator runs, inverter input runs and battery-related DC routing where the system design calls for solar-grade cable. It is not the cable to treat like ordinary building wire. In a Lahore rooftop hybrid system, the cable may sit across the slab and through conduit in high summer heat. In Faisalabad, long shed roofs and inverter rooms make voltage-drop planning important. In Karachi, sun, salt air and rooftop exposure make insulation quality even more important.

How to Choose the Right Solar Cable Size

Do not choose only on price. Solar cable selection depends on DC current, route length and voltage-drop target. A short domestic string run may suit 4mm, while a longer or heavier run often pushes the decision toward 6mm. If a designer already has a voltage-drop calculation, follow that instead of guessing by habit.

Solar DC Cable vs Ordinary Electrical Wire — Why CNC?

What This Product Does NOT Protect Against

This solar DC cable does not replace a DC breaker, DC fuse, SPD, isolator or voltage protection device. It does not stop lightning surge damage, DC short-circuit faults, or poor inverter settings. It also does not fix a bad cable-size decision. If the run is too long for the chosen size, voltage drop and heating problems remain. Cable alone is not a protection device.

For a complete DC side, pair this cable with the right DC Breakers, Fuses, DC SPD, DC Isolators, and where relevant, a complete Solar DB Bundle.

Installation Guide

1. Select 4mm or 6mm only after checking DC current, run length and voltage-drop allowance.
2. Keep polarity clear and use red and black routing consistently from panel side to inverter side.
3. Protect the run physically with the right conduit, tray or route support where required.
4. Terminate with proper solar-rated connectors and do not mix poor-quality DC accessories into a good cable run.
5. Keep DC cable away from sharp bends, hard abrasion points and needless rooftop exposure where a cleaner route is possible.

Frequently Asked Questions

1. What is solar DC cable used for?

It is used to connect solar panels, DC isolators, combiner points and inverters on the PV side of a solar system. It is meant for photovoltaic DC duty, not just ordinary general wiring.

2. Is this cable suitable for both on-grid and hybrid systems?

Yes. The product category is suitable for standard PV interconnection work in on-grid, hybrid and other solar DC-side applications where the design current and run length are matched properly.

3. Should I choose 4mm or 6mm solar cable?

Choose based on current, route length and voltage-drop target. Shorter lighter runs often suit 4mm. Longer or heavier runs often push the decision toward 6mm.

4. What price is shown for this solar DC cable in Pakistan?

At the time checked, the live CNC Electric Pakistan page displayed Rs.20,000 for the product listing.

5. Does the live page show a separate price for every red, black, 4mm and 6mm selector?

Not clearly. The page shows the selector options, but separate confirmed variant-by-variant prices are not clearly published on the visible page snapshot, so they have not been guessed.

6. Why not use ordinary electrical wire for solar strings?

Because solar cable is built for DC-side PV duty, outdoor UV exposure and harsher temperature conditions. Ordinary house wire is not the right substitute for long-term exposed solar interconnection work.

7. Is this cable tinned copper?

Official CNC photovoltaic cable family material describes the conductor as tinned copper built to EN 60228 / IEC 60228 class 5 style conductor practice.

8. Does solar cable alone protect my inverter from surge or fault damage?

No. Cable carries power. Protection still needs the right DC breaker, fuse, SPD and isolator around the system.

Solar DC cable is not the place to save a few thousand rupees and create years of voltage-drop, heat and outdoor-life problems.
