40W 12V dual battery solar kit for camper / boat with controller and cable

Ready to unlock true freedom for your camper or boat? The 40W 12V Dual Battery Solar Kit offers a smart, reliable way to power your journeys. This complete system delivers consistent, free electricity to keep both your essential engine and leisure batteries charged. Enjoy peace of mind knowing your power needs are met, whether you're exploring remote landscapes or anchored in a quiet cove. It’s built for adventurers who need dependable energy without the fuss.

This comprehensive kit brings together everything you need for efficient dual battery charging:

• Powerful 40W Monocrystalline Solar Panel: Highly efficient and built for permanent outdoor use in all weather conditions.
• Smart Dual Battery Charge Controller: A 10A 12V/24V controller that intelligently manages and protects two batteries independently.
• Plug-and-Play Connectivity: Includes 5 meters of special solar cable with pre-crimped MC4 connectors for easy setup.
• Designed for Dual Systems: Perfect for caravans, camper vans, boats, or any setup with separate engine and leisure batteries.
• Expandable Power: The controller supports up to 160W of solar input, allowing you to add more panels later without changing your controller.

Your Solar Panel: Power Anytime, Anywhere

The included 40W 12V monocrystalline solar panel is built tough. It’s fully waterproof, ready for any weather, and designed to provide stable, free electricity for years. Its advanced 5-busbar solar cells are more efficient than older designs, pulling more power from a smaller area – perfect for tight spaces on your RV or boat. These innovative cells also perform exceptionally well in warmer climates, ensuring reliable power even when temperatures rise. You can easily charge your 12V batteries or even directly power applications like electric motors or pumps that aren't sensitive to voltage changes. The included 5-meter solar cable is specially designed to minimize power loss, even on hot roofs, and comes with standard MC4 connectors for simple expansion.

Your Charge Controller: Smart & Safe Battery Management

This kit features a robust 10A 12V/24V dual battery charge controller, engineered to charge and protect two batteries at once, independently. Using advanced PWM technology, it not only ensures your batteries are charged optimally but can also extend their lifespan and even recover some lost capacity. You can prioritize which battery gets charged first, and the controller intelligently diverts power once one battery is full. It’s packed with safety features like overcharge protection, reverse polarity protection, and it even stops power draining back to the panel at night. Handy LED indicators show your battery status, and you can select the correct battery type (sealed, gel, or flooded) for precise charging. For optimal performance, especially if your controller is far from your batteries, consider adding an optional external temperature sensor. Plus, you can upgrade your system later by adding up to three more 40W solar panels without needing a new controller.

Important Notes for Your Setup:

This is an essential solar kit, meaning it provides the core components for power generation and management. Please be aware that mounting accessories and battery cables are not included. If you require these items, they should be purchased separately to complete your installation. Also, remember that while the solar panel is designed for outdoor use, the solar charge controller is not waterproof and must be mounted indoors to ensure its longevity and proper function.
