Compatible with 12V Battery Charging or Maintenance: This solar panel is designed for charging and maintaining 12V rechargeable batteries, including LifePO4, lithium-ion, AGM, SLA, GEL, EFB, and MF. It can power RVs, cars, boats, trailers, tractors, trucks, motorcycles, lawn mowers, water pumps, door openers, electric fences, street lamps and more to extend battery life. Under ample sunlight conditions it generates up to 180Wh of electricity and enters maintenance mode when fully charged.(Note: Our solar panels have been rear-mounted controller and cannot charge mobile power stations that already have built-in controller.)
12V Ultra Smart PWM Technology Charging Controller: Featuring advanced ultra-intelligent PWM technology (maximum power point tracking), this algorithm optimizes sunlight conversion with a tracking efficiency of up to 99% and peak conversion efficiency reaching 98%, which is about 20%-30% higher than similar brands.
23% High Efficiency: Made from high-efficiency monocrystalline silicon and A+ class N-type module cells that are minimally affected by temperature fluctuations. It excels in bifacial power generation even on cloudy days. By tilting the panels towards the sun efficiency can reach up to 24%. The design includes a 12BB power grid line for lower attenuation and only a 0.5% annual degradation rate ensuring a lifespan of up to 25 years.
Maintenance-free: The solar trickle charger automatically stops charging when the battery is full and resumes when it discharges, requiring no maintenance. It is a fully automatic 12-volt solar charger.
Multi-layer Sturdy Protective Material: The solar panel features durable low-iron tempered glass, transparent EVA film, N-type monocrystalline silicon cells, waterproof backing, and anti-corrosion aluminum frame for 100% water and rust resistance. It operates reliably in extreme temperatures from -40? to 185? and withstands strong winds (2400Pa), hail, snow loads (5400Pa), sandstorms, thunderstorms, blizzards, and other severe weather conditions.
Visible Battery Capacity and 3 Types: A PWM intelligent charging controller at the back of the 50W solar panel displays battery capacity (25%, 50%, 75%, 100%) and type (GEL/AGM/lithium) via LED indicators for easy monitoring.
Built-in Protections: The rear controller is user-friendly with various internal protections against reverse connection, overvoltage, overcharge, overdischarge, overcurrent, overload, short circuit, reverse polarity, overheating, water damage, and sparks—ensuring comprehensive battery safety.
Widely Applied: The versatile 50W solar panels are ideal for various off-grid applications including roofs, RVs, camping setups, mowers, motorcycles, solar stations, monitors, tractors, yachts, street lamps, trailers, ATVs, home, tents, cars, pumps, electric fences, door openers, etc.
Quality Service: We provide 12 months replacement and warranty after-sales service. If you have any questions, please feel free to find us, we will do our best to solve your problems.
