Color: 30a Overview This flexible camping solar panel kit is designed for mobile power on RVs, boats, sailboats, yachts, trucks, cars, buses, cabins, campers, tents, and trailers. The thin, lightweight panels bend up to 30 degrees for curved surfaces, are easy to mount, and withstand harsh weather conditions. The included charge controller intelligently charges 12V batteries and protects against overcharge, overdischarge, and overvoltage. Key benefits Flexible and portable: Panels can bend up to 30 degree for installation on curved roofs and decks. Thin 2.5 mm profile and light weight make transport and mounting easy. Reliable in harsh conditions: Rated for wind resistance, snow load, and hail impact, with an operating ambient temperature range from 40C to +85C (40F to 185F). Simple installation: Six predrilled mounting holes allow secure attachment to a variety of surfaces. Multiple panels can be connected in series for larger systems. Built for longevity: Multilayer sheet lamination improves cell performance and extends service life. Complete charging solution: Converts sunlight to electricity and, with the supplied 30A/40A charge controller, intelligently charges 12V batteries while providing battery protection. Practical applications RV and camper rooftop charging: Mount on a curved RV roof to off the coach house battery while parked or driving. Marine use: Flexible shape fits decks and cabin roofs on boats and yachts for maintaining house batteries during cruises. Remote cabins and trailers: Lightweight panels provide a mobile power source for lighting, small appliances, and battery maintenance at offgrid locations.
