Note: Not intended for use with lithium batteries.

This permanently mounted Redarc solar system can help extend your off-grid campout if you have low energy demands. It provides an easy way to charge your RV batteries with clean, renewable power. Using the 120-watt solar panel, this system collects solar energy to create DC power that passes through a solar charge controller into your battery. It can extend your off-grid campout by a day or so if you only need power for a fan, LED lights, and recharging your phone.

The solar panel mounts permanently to your roof using the included corner brackets. The solar controller will monitor the battery, maintaining it and preventing it from being overcharged.

Monocrystalline Solar Panel

Redarc solar panel installed on an RV roof

The charging process starts with the solar panel, which mounts permanently with screws or other mounting hardware (sold separately). When solar energy interacts with the silicon cells in the panel, it generates a flow of DC electrical current that charges your battery. Each of the monocrystalline cells is made from a single crystal of silicon, so the electrons that create the current have more space to move, making this panel more efficient than one with polycrystalline cells. And in optimal sunlight conditions, the panel produces 120 watts per hour.

Smart Solar Controller Charges and Protects Battery

The solar controller prevents harmful overcharging by adjusting the power generated by the solar panel before it reaches your batteries. It uses pulse width modulation technology to regulate the output through pulses that provide a consistent charge. Typically, PWM controllers are a good fit for smaller systems, rather than using more expensive MPPT solar controllers.

Redarc 10 amp solar charge controller

The controller is compatible with multiple battery types and includes preset charging profiles for sealed/gel and AGM batteries. The optional remote - sold separately - is required for flooded/wet cell and calcium batteries.

LED indicators provide information on the current solar panel output. The lights will tell you if the panel is providing a charge, if the battery is charging, and if the battery is fully charged. This will charge a battery reading at least 9V in a 12V system, or a battery bank reading 18V in a 24V system.

Optional Remote Monitor Offers More Info and Options

While this kit will work perfectly for a hands-off approach to giving your battery an extra boost, the optional Redarc Remote Monitor (RED83VR - sold separately) is an easy way to upgrade your setup. This remote would be required if you want to use this system with flooded or calcium, as it is the only way to change the solar controller's battery type.

This monitor's digital display lets you see the solar array's charging status, read your battery's voltage, check electrical usage, and other info. Since your solar charge controller is likely to be installed somewhere close to your battery bank, being able to check on your solar status from inside your RV using this remote will be far more convenient. While not necessary, this is an upgrade we highly recommend.
