Feature 1Wide Applicability: This polysilicon solar charging panel is suitable for motorcycles, boat, tractor, trailer, truck, lawn mower, RV etc. Also be used for gate openers, electric fences, chicken coops, sheds, and lights. 2High Efficiency: Made of polysilicon and metal, high temperature and water resistance, and can easily cope with the harsh outdoor environment. It has a high charging efficiency to achieve the most ideal charging effect in a limited space. 3Sturdy Construction: The solar panel frame is made of low iron tempered glass surface and rust resistant aluminum frame, which can prevent wear and tear for a long service life. The polycrystalline silicon panel can generate more electricity every day under sunny conditions. 4Battery Protection: The charge controller can prevent battery overcharge, overdischarge, overvoltage, short circuit and reverse current problems. It prevents the battery from depleting due to long time non use. Indicators on the controller make it easy to know the status of charging and discharging. 5Built in Intelligent Controller: The charging algorithm of the solar battery charger has been upgraded to automatically charge during the day and shut down at night without consuming battery power.Item Type:SolarPanelCharger SetSolar Cell: Polycrystalline siliconProtection Level: Ip65Solar Panel Power: 10WController System Voltage: 12V/24V AdaptiveSolar Panel Working Voltage: 18VSolar Panel Open Circuit Voltage: 21.6VSolar Panel Short Circuit Current: 0.55A (Maximum)Output Port: Dual USB, DC5521 FemaleProduct Features: Integrated voltage regulator module, 5V dual USB voltage regulator outputSolar Panel Size: Approx. 435 x 200 x 3mm / 17.12 x 7.87 x 0.118inFitment: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 .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; }Package List1 x Solar Panel1 x Controller1 xClip Line1 x Car Charging Cable4 x Sucker2 x Buckle1 x Instruction Manual
