Add another Redarc solar panel to your solar system to increase your charging power and extend your off-grid campout. Multiple-panel solar arrays are most efficient when you use panels with the same wattage, so we recommend adding this to a system with other 50-watt panels. When panels of different wattages are combined, the panel with the larger rating will have its performance reduced.

Be mindful of the amperage and wattage limitations of your solar charge controller, as exceeding those limits may cause the solar array to not function.

Wiring panels together

Redarc offers multiple options for connecting multiple panels. It's important to understand what effect they will have. If you are unsure of what would work best for you, you should consult an electrician or dealer for professional advice and installation.

Three options for wiring Redarc solar panels together

Redarc offers Anderson connectors to wire panels in series (RED53VR) or parallel (RED59VR). By wiring your panels in series, you will increase the total panel voltage output. By wiring your panels in parallel, you increase the total amperage. In both cases, you get increased battery charging power going to your solar charge controller. If you increase your total voltage or amperage beyond what your charge controller can handle, it will not function properly. In solar arrays of 4 or 6 panels, you can wire half in series and half in parallel, so neither the volts nor amps exceed your controller's limitations. By being mindful of these options, it can save you the pain of having to buy a more expensive solar charge controller that can handle the increased input.

Redarc also offers MC4 style connectors for wiring panels in parallel (RED78VR). Since the connectors on the panel itself use MC4 connections, this eliminates the need for an MC4 to Anderson adapter and will make for a cleaner install.

Mount for joining 2 Redarc solar panels

For installing panels on the roof of your RV, also remember to get some Redarc Solar Panel corner mounts (RED79VR) and side mounts (RED89VR). The side mounts are especially great for multi-panel arrays, as they hold two panels together at their corners, conserving space on your roof while holding panels securely.

Expand your Redarc solar array with an additional 50-watt panel to charge your batteries faster and enjoy an off-grid campout longer. Connects to your solar setup with included MC4 connectors.


If you do a lot of remote camping, this works really well. Combined with a BCDC charger, this is the ultimate batery charging system.


Paul is awesome

  • AGM Battery Charging Recommendation Between Smart Charger or Solar Panel
    If your trailer is going to be parked near an outlet when you aren't using it then a smart charger will be more cost-effective and still sufficiently charge your battery, but if your trailer isn't near an outlet then you'll need to go with solar panels. I personally like the solar panel setup the best because it means your batteries can virtually be charged anywhere there is sun but a lot of this has to do with your budget so below is what I recommend out of either system - pricing can...

  • DC to DC Battery Charger & Solar Panel For 90 Amp Hour Trailer Battery
    We do have exactly the parts you need for a DC to DC charger and solar panel which can be installed onboard a trailer, though it wouldn't use the 7-way connector. Wire (6 gauge) would need to be run directly from the battery and then connected with a quick-connect set. Here's exactly what you will need: - Redarc In-Vehicle BCDC Battery Charger - Dual Input - DC to DC - 12V/24V - 25 Amp # 331-BCDC1225D - 40-Amp MIDI Fuse Kit for Redarc In-Vehicle 25-Amp BCDC Battery Charger # 331-FK40 -...
