Solar Panel

About this product Highly efficient charging with 20W, 25W, 30W, or 50W output and a 12V output voltage ensures a reliable power supply for your vehicle battery. The monocrystalline solar cells offer high conversion efficiency and enable faster charging, even in varying light conditions. Depending on the model, the panel is equipped with highly transparent tempered glass or robust ETFE film. These materials improve light transmission and increase durability outdoors. Ideal as a solar battery maintainer for continuous maintenance and stabilization of the battery voltage. Intelligent charge control via an integrated or external MPPT controller or microcontroller automatically optimizes the charging process. Multi-stage protection functions saf eguard against overvoltage, overcurrent, short circuit, deep discharge, overcharging, and overheating. Some models automatically stop charging when 12V is reached and resume it when the voltage drops. This extends battery life and ensures saf e use. Suitable for continuous maintenance charging of sensitive 12V batteries. Broad compatibility with various 12V battery types, such as LiFePO4, Li-ion, AGM, Gel, SLA, and EFB, makes this solar panel incredibly versatile. It's perfect for cars, RVs, boats, motorcycles, trailers, caravans, lawnmowers, water pumps, gate openers, snowmobiles, or garden sheds. Thanks to different power levels, the system is suitable for both smaller vehicles and larger applications with higher energy demands. It's a flexible solution for seasonal use or long-term outdoor installations. The weatherproof construction with IP65 or IP67 protection ensures reliable operation in temperatures ranging from -40°F to 185°F (-40°C to 85°C). The modules are resistant to wind, rain, snow, and intense sunlight. Select models feature a 0°–60° adjustable mounting bracket for optimal sun orientation. Lightweight ETFE versions offer additional advantages in terms of low weight and flexible mounting options. Complete kits with various connection options simplify installation. Depending on the model, the package includes a 122-inch (3100 mm) extension cable, a 43.3-inch (1100 mm) alligator clip cable, an O-ring cable, a cigarette lighter plug, and M6 screws or suction cups. This allows for direct connection to various battery types. The simple plug-and-play installation saves time and enables quick setup. Key Differences The models vary in power output from 20 W to 50 W, making them suitable for different battery sizes and applications. Some versions have an integrated MPPT controller, while others are equipped with an external MPPT controller or microcontroller. The surface materials vary between tempered glass and ETFE film, which affects weight and mounting flexibility. The protection rating ranges from IP65 to IP67, depending on the model, resulting in different levels of water resistance. Certain versions include an adjustable 0°–60° bracket, while flat models are supplied without a bracket. The scope of delivery varies depending on the additional O-ring cable, cigarette lighter plug, suction cups, or number of screws. Weight and dimensions vary significantly depending on the power level and design. ...
