Best Solsquare Multicore Cables for Solar Projects
Cables are among the most ignored yet important components when it comes to the effectiveness and efficiency of a solar power build or construction. They might not be as patent as solar panels, or as advanced as the inverters, but without the appropriate cables, your solar project can experience power loss, safety challenges and shorter life cycle.
When it comes to large and professional solar projects, multicore cables are the preferred choice, especially for laying out an application that uses multiple installs within the same protective sheath. Yes, as well as answering the brief, there are many brands to choose from if you want performance, reliability, and price; Solsquare multicore cables have certainly built a strong reputation for all of these great features.
Why Cable Quality is Crucial for Solar Systems
Solar cables encounter far harsher working environments than the house-hold wiring. They have to work effectively and under safe conditions in hostile environments which may be hot, wet, dusty and exposed to UV radiation over decades.
A good Solar cable should be able to:
- Resist long periods of sunlight.
- Work under large temperature range.
- Resist moisture, chemicals, and mechanical wear.
- Carry current without excessive voltage drop.
- Ensure that electrical safety lasts through the decades.
It is difficult to provide an accurate figure of premature failure rates, but a failure rate of 20 percent as demonstrated in the Grid Impact report by Extra Effort can easily increase the cost of replacing the cables not to mention downtimes which may greatly affect the ROI of a solar installation. That is why specialists insist on making use of the cables of respected brands such as Solsquare.

What Are Multicore Cables?
The multicore cable is made in such a way that there are several insulated conductors covered in the same outer jacket. This makes them good in applications having many locations that require wiring but are desirable to organize into only one massive cable path.
In solar power projects, multicore cables are particularly useful for:
- Connecting inverters to the grid.
- Carrying both power and signal lines together.
- Running AC power from combiner boxes to distribution panels.
Advantages of multicore cables include:
- Simplified installation - fewer cables to run and manage.
- Better protection - all cores are shielded under a single outer layer.
- Increased durability - less wear and tear compared to multiple single-core runs.
- Time and cost efficiency - quicker installation and reduced labor costs.

3. Product Range
Available in sizes from 0.5 sq.mm to 50 sq.mm, with current ratings from 6A to 125A, Solsquare’s multicore cables are suitable for everything from small rooftop systems to large utility-scale solar plants.
Applications in Solar Projects
While single-core solar cables are standard for direct current (DC) connections between panels and inverters, multicore cables play an essential role in alternating current (AC) and auxiliary connections:
- AC Output from Inverters: Multicore cables can carry three-phase AC output efficiently from inverters to the main grid connection point.
- Control and Monitoring Circuits: Multiple control signals and low-voltage power lines can be run together for improved organization.
- Hybrid Systems: In systems combining solar and battery storage, multicore cables can integrate inverter, battery, and grid connections seamlessly.
- Commercial Solar Rooftops: For large rooftop projects, multicore cables reduce clutter and make cable management much easier.
Technical Overview
| Size (sq.mm) | No. of Strands | Current Rating (Amps) | Max Conductor Resistance (Ω/km @ 20°C) |
|---|---|---|---|
| 0.5 | 16/0.20 | 6 - 9 | 39.0 |
| 1.5 | 30/0.25 | 18 - 24 | 12.1 |
| 4.0 | 56/0.30 | 32 - 42 | 4.95 |
| 10.0 | 140/0.30 | 75 - 95 | 1.91 |

- Long life – Built to withstand 30 years of life in the outdoor environment.
- Availability-Easy to meet in various areas so that it can be bought in a short time.
Installation Tips for Multicore Cables in Solar Projects
- Respect bending radius – Avoid sharp bends that can damage the conductors.
- Use proper routing – Install in trays, conduits, or protective covers.
- Plan cable runs efficiently – Minimize unnecessary length to reduce voltage drop.
- Secure terminations – Ensure clean, tight connections to avoid hot spots.
- Separate AC and DC runs – Reduces electromagnetic interference.
The Future of Solar Cabling
With solar becoming more high powered and systems processing greater voltages and currents, the cables will have to be even stronger, more efficient and flexible. Multicore cables from Solsquare are already designed with future requirements in mind-capable of supporting modern solar plants that demand long service life, minimal maintenance, and maximum safety.
