Charge Visualization The indicator lights give a clear view of charging status. Blue indicates exposure to sunlight, red indicates charging, and green indicates a full charge. If a short circuit occurs, all three lights turn off. Intelligent Protection A builtin charging microprocessor and improved charging algorithm provide overvoltage protection, overcharge protection, and short circuit protection. This ensures safe charging and maintenance of 12V batteries. Higher Conversion Rate The panel uses a distribution of regular convex points that enhances secondary light propagation, maximizing solar energy absorption and significantly improving photoelectric conversion efficiency. Durable Construction Made from waterproof and dustproof PET material, reinforced with an epoxy board bottom plate for added durability. The charger kit remains sturdy even if the panel is damaged, while maintaining charging efficiency. Use scenarios Offgrid outdoor charging for camping or remote work sites: keep 12V batteries powered for lighting, radios, and small equipment. Marine or RV applications: maintain and protect 12V battery charge during travel or storage, reducing the risk of battery discharge. Emergency backup or rural installations: provide reliable solar charging for 12V batteries when grid power is unavailable.
