Feature:1. Simple Operation: Our solar charge controller can automatically identify 12V/24V system voltage and has LED digital display, single key operation, simple and convenient operation2. Good Battery Life: Adopting the ternary charging algorithm, the battery is balanced and charged once a week, which can effectively prevent the battery from imbalance and vulcanization and prolong the life of the battery3. 4 Working Modes: Our solar charge or discharge controller has 4 working modes, which are convenient for use on various street lights and monitoring equipment, with various status indications4. Emergency Handling: External temperature sensor for high accuracy temperature compensation, with power protection data function, when the power system fails, the parameters can be stored without resetting5. Protection Range: Overcharge protection, over discharge protection, overload protection, short circuit protection, reverse polarity protection, TVS protectionSpecification:Item Type: PWM Solar Charge ControllerMaterial: ABSSystem voltage: 12/24V autoSystem current: 10ASolar input voltage: Less than 55VWorking temperature: -35℃ to 65℃Protection level: IP30Package List:1 x PWM Solar Charge Controller1 x User GuideNote:1. When connecting the 24V system, the terminal voltage of the battery panel may exceed the safe voltage for human body. If operation is necessary, insulated tools should be used and hands must be dry.2. If the battery is connected in reverse, the controller will not be damaged, but there may be negative voltage output at the load side, which may damage your load equipment. Please take care to avoid this situation.3. In a 24V system, if the b
