Features:The controller has a design of household type and street light type, which is reasonable and thoughtful.This controller is suitable for 12V/24V battery systems.The controller has functions of light control and time control(street light type).This control has over-charge, over-discharge, over-current, short-circuit, reverse connection and other protection measures.The controller has power-down protection (that is, after the button is adjusted, the controller is powered off, and the last adjusted data is also saved).It has a strong charge, a uniform charge, and a floating charge three-stage type P to adjust the charging mode.Specifications:Condition: 100% Brand NewMaterial: ABSRated Voltage: 12V/24VStrong Charging Voltage: 14.8V/29.6VBalanced Charge: 14.5V/29.0VFloating Charge Voltage: 13.7V/27.4VUndervoltage Protection: 10.8V/21.6VUndervoltage Recovery: 13.0V/26.0VMaximum Charging Current: 5AMaximum Load Current: 5AWeight: approx. 161g / 5.7ozController Protection: Overload, reverse connection, over discharge, over charge, short circuit, etc.Charging Mode: PWM Adjustment ModeRain Control: when the rainwater in the sink is soaked into the rain control lineUse Altitude: 5500m (More than 2000m need to reduce power usage)Working Temperature: -40 C-60 CSize: approx. 11.9*7.2*3.4cm / 4.7*2.8*1.3inProtection Level: IP56Current: 5A, 10A, 15A (Optional)Product Installation:The installation environment: installed in a dry and ventilated place.The installation sizeThe wiring methodA. Connect the battery first (the positive pole is to the left) and connect it correctly.B. Reconnect the battery board (positive side to the left) and connect correctly. The charging indicator light starts to light up and enter the charging state. Otherwise check the line.C. Reconnect the light source (the bulb and the positive pole to the left) to connect correctly, and the bulb will emit light (the street lamp type will be extinguished during the day, undervoltage and overvoltage will be extinguished). Otherwise check the line.D. Finally, connect the rain control line and connect the rain control line to the water tank above the lamp to check if it is secure.(The rain control line can't be too long, it can't exceed 1 meter, too long affects the rain control sensitivity, the shorter the more sensitive)Note: The ABC must be connected in order, otherwise the controller will be damaged.Package list:1 * Charge Controller1 * Instruction ManualNote:1.Please allow 0-1 inch error due to manual measurement.
