Overland Solar 20 Ft Extension Cable for All Kits
Overland Solar 20 Ft Extension Cable for All Kits
This is a 20-foot Overland Solar extension cable with Anderson SB50 connectors on both ends. It drops inline between your solar panel and the charge controller, adding 20 feet of reach so you can place the panel where the sun is instead of where the rig is parked. Stack it with a kit's existing lead and you get roughly 40 feet of total run.
Two builds. The 12 AWG version is non-UV-coated — more flexible and easier to coil, sized for a cable that lives in a bag most of the year and only sees the sun a few weeks at a time. The 10 AWG version is heavy UV-coated cable: stiffer and heavier, but built to sit out in the sun for weeks without the jacket breaking down. The heavier 10 AWG also keeps voltage drop lower on longer total runs.
Both ends terminate in black Anderson SB50 housings, the same connector on Overland Solar kits, so it plugs straight in with no adapters. SB50 housings mate by color: black and gray go together, red only mates with red. The connector is rated to 50A hot-plug and carries up to 120A static once mated — far above what a single overland panel pushes.

Overview
A 20-foot Anderson SB50 extension cable for Overland Solar kits. It adds reach between the panel and the charge controller so the panel can sit in the sun while the rig sits in the shade. Choose 12 AWG non-UV for flexibility or 10 AWG UV-coated for long-term sun exposure.
Key features
- 20 ft per cable; stacks with a kit lead for ~40 ft total run
- Anderson SB50 connectors on both ends — plug-and-play with Overland Solar kits
- 12 AWG non-UV-coated: more flexible, packs smaller, for short-term deployment
- 10 AWG heavy UV-coated: jacket built for long-term sun exposure, lower voltage drop
- SB50 rated 50A hot-plug, up to 120A static once mated
- Black housings standard; red available on request (note at checkout)
Use cases
Built for shaded or wooded campsites where the rig parks under cover but the sun sits 20-plus feet away. The added length lets you set the panel in a clearing, on a rock, or up a slope and still reach the controller. It also gives flexible-panel users room to chase the sun through the day without unplugging and re-staking the whole kit.

- Connector rating: 50A hot-plug / up to 120A static (SB50)
- Total run with kit lead: ~40 ft
- Color mating: black/gray mate together; red mates red only
- Ship weight: 12 AWG ~3.0 lb (1361 g) / 10 AWG ~4.0 lb (1814 g)
What's the difference between the 12 AWG and 10 AWG versions?
The 12 AWG cable is non-UV-coated — more flexible and lighter, sized for a cable that stays in a bag most of the year and only deploys a few weeks at a time. The 10 AWG is heavy UV-coated cable: stiffer and heavier, but the jacket holds up to long-term sun exposure and it drops less voltage on longer total runs. Pick by how long the cable will stay outside, not just by price.
Will it plug straight into my existing kit?
Yes. Both ends use Anderson SB50 connectors, the same ones on Overland Solar kits, so it goes inline between the panel and the controller with no adapters. Watch the housing color: black and gray SB50 housings mate together, and red only mates with red.
How many amps can it handle?
The SB50 connector is rated for 50A when hot-plugging (connecting under load) and carries up to 120A static once mated. That's well above the current a single overland solar panel produces, so the connector is not the limiting factor in a typical kit.
Can I leave the non-UV cable deployed all season?
No — that's the wrong cable for it. The non-UV-coated 12 AWG is meant for short stints in the sun; left out for weeks the jacket degrades faster. If the cable will stay deployed for long stretches, choose the 10 AWG UV-coated version instead.
