1、DURABLE MATERIAL: : The solar panel frame has a low iron toughened glass surface and aluminum frame, which can prevent weathering and wear and has a long service life. The panels are made of highly efficient monocrystalline silicon, which generates more electricity in full sunlight. 2、BATTERY PROTECTION: The charge controller can prevent battery overcharge, overdischarge, overvoltage, short circuit and reverse current, extend battery life. 3、INTELLIGENT CONTROL: Automatic charging during the day, shutdown at night, reduce nighttime consumption, improve daytime efficiency, and do not consume battery power. 4、HIGH EFFICIENCY: The monocrystalline silicon panel, which can generate more power under full sunlight and achieve the most ideal charging effect in a limited space. 5、WIDE APPLICATION: It can be widely used in batteries for motorcycles, boat, tractor, trailer, truck, lawn mower, RV etc. Also be used for gate openers, electric fences, chicken coops, sheds, and lights.
