PRODUCT DESCRIPTION
Heavy-Duty 10 AWG Solar Panel Extension Cable Pair
Maximize your off-grid power efficiency and extend the reach of your solar array safely with this premium 10 Gauge Solar Panel Extension Cable Pair. Designed specifically for outdoor environments, this set includes one red and one black high-output cable pre-terminated with secure male and female solar connectors on both ends. Whether you are wiring a home backup system, a workshop, or an off-grid cabin setup, these heavy-duty 10AWG wires ensure minimal power loss over long distances.
Key Performance Features
- UL 4703 Certified Wire: Engineered explicitly for photovoltaic power systems, providing superior resistance against moisture, severe UV exposure, and environmental corrosion.
- Plug-and-Play Solar Connectors: Pre-installed male and female solar connectors form a tight, secure connection right out of the box.
- All-Weather Reliability: Rated at IP67 waterproof and built with high-grade TPE insulation to withstand extreme temperatures from -40°F up to 194°F.
- Maximum Efficiency: Constructed using high-grade tinned copper to deliver exceptional conductivity while preventing oxidation over a 25+ year service life.

Frequently Asked Questions
What is a 10 gauge solar extension cable used for?
A 10 gauge solar extension cable is used to connect solar panels to charge controllers, combiners, or power inverters over longer distances. The thick 10 AWG wire minimizes voltage drop, making it the industry standard for safe outdoor solar installations.
Are these solar cables safe for direct burial or outdoor use?
Yes. These cables feature a specialized TPE jacket that is UL 4703 certified, meaning they are explicitly formulated to resist intense UV rays, moisture, and corrosion, ensuring long-term durability in permanent outdoor exposures.
Why is tinned copper better than bare copper for solar wiring?
Tinned copper features a thin layer of tin over the copper core. This prevents the metal from oxidizing and rusting when exposed to outdoor moisture, dramatically extending the life of your cables up to 25+ years.
Will this cable work with my Rich Solar panels' MC4 connectors?
Yes. This cable ships with standard male/female MC4-compatible connectors, which match the output connectors used on Rich Solar panels and most other solar panels on the market.
How long of a cable run can I use before losing too much power?
Longer runs increase voltage drop, which reduces the power actually reaching your controller. For 10 gauge cable at typical solar currents, keeping runs under roughly 25-30 feet keeps voltage drop minimal; longer runs may need a heavier gauge cable.
Is this cable rated for outdoor and weather exposure?
Yes. It's built with weatherproof insulation and IP-rated connectors so it can be run outdoors, on a roof, or through an exterior wall penetration without additional protection, within its rated temperature range listed in the specifications above.
Can I use this to extend the distance between my panel and charge controller?
Yes — that's the primary use case. Connect one end to your panel's MC4 output and the other to a matching MC4 extension or your controller's input leads to extend the total cable run.
Do I need one pair or multiple pairs for my system?
One pair (one positive, one negative lead) connects one panel or one parallel string to your controller. If you're wiring multiple panel strings separately back to a combiner or controller, you'll need one pair per string.
Is this cable compatible with panels from other brands?
Yes, as long as the other panel uses standard MC4 connectors, which is the industry standard across most residential and off-grid solar panels, not just Rich Solar.
Can I cut and re-terminate this cable if I need a custom length?
The cable itself can be cut to length, but re-terminating with new MC4 connectors requires a proper MC4 crimping tool and connector ends to maintain a weatherproof, low-resistance connection — if you're not equipped for that, it's safer to order the closest pre-made length instead.
