Features:The controller has a design of household type and street light type, which is reasonable and thoughtful. This controller is suitable for 6V/12V battery systems. The controller has functions of light control, time control and rain control. This control has over-charge, over-discharge, over-current, short-circuit, reverse connection and other protection measures. Scientific and rigorous shape design, using high-level protection means. It has a three-stage PM adjustment charging method with strong charge, balanced charge and floating charge.

The installation environment: installed in a dry and ventilated place.2. The installation size3. The 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, under voltage and over voltage 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.
