Feature 1DURABLE 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. 2BATTERY PROTECTION: The charge controller can prevent battery overcharge, overdischarge, overvoltage, short circuit and reverse current, extend battery life. 3INTELLIGENT CONTROL: Automatic charging during the day, shutdown at night, reduce nighttime consumption, improve daytime efficiency, and do not consume battery power. 4HIGH EFFICIENCY: The monocrystalline silicon panel, which can generate more power under full sunlight and achieve the most ideal charging effect in a limited space. 5WIDE 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.Item Type:Solar Panel .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Material: Monocrystalline siliconProtection Level: IP65Solar Panel Power: 20WSolar Panel Operating Voltage: 18VSolar Panel Open Circuit Voltage: 21.6VSolar Panel Short Circuit Current: 1.11A (maximum)Controller System Voltage: 12V/24V adaptiveOutput Port: Dual USB, DC5521 femaleSolar Panel Size: Approx. 330 x 360 x 3mm / 13.0 x 14.2 x 0.1inProduct Characteristics: Integrated voltage regulator module, 5V dual USB voltage regulator outputApplication: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.Package List1 x SolarPanel1 x Controller1 xClipLine1 x Car Charging Cable4 xSucker2 x Buckle1 x User Manual
