Function: 1. Multi-Function Solar Panel - Ideal for charging 12V batteries or multiple panels that can be daisy-chained to charge 24/48V batteries or for grid-tied applications. 2. Flexible design, can be curved to a maximum arc of 30° to enhance sunlight absorption. 3. It can withstand high wind pressure (2400 Pa), snow loads (5400 Pa) and temperature extremes, and has a durable aluminum frame that allows the panels to last for decades. 4. High charging efficiency, energy saving and environmentally friendly. 5. The panel can be mounted on a motorhome, boat, cabin, tent, car, truck, trailer or other irregular surface. Specification: The main function of this product is to power most 12V lead acid batteries, charge 12V lithium batteries and much more. The solar panel can also be bent 30° and installed in RV, fishing boat, wooden house, tent and any other outdoor scene. The power supply is energy-saving and environmentally friendly, making it the perfect companion when working outdoors, traveling or training at the campsite.
