Versatile Compatibility: The perfect solar power kit for a variety of off-grid applications such as sheds, cabins, door openers, and more using 12V batteries, as well as for AGM, flooded, gel, deep cycle, and sealed lead acid etc. Battery charging and maintenance in cars, RVs, boats, boats, trailers, campers, pumps and more. Charger controller: Advanced PWM algorithm can fully protect the battery: undervoltage/overvoltage, output overload, short circuit and anti-reverse protection. It can greatly increase the charging efficiency by 20%, and has no additional power consumption. High-efficiency monocrystalline silicon solar cells, heavy-duty anodized aluminum frame, corrosion-resistant aluminum frame, and tempered glass coating protect the panel from weathering and abrasion. Lightweight and Durable: The four corners are equipped with a protective case, which better protects the glass plate and is stronger. Pre-drilled holes on the back of the panel for easy installation, easy installation and fixing.
