DC 12V Solar Power Supply System for 4G Security Camera

Construction and installation are convenient and convenient, saving time and effort; With photovoltaic panel angle mark, it is convenient to confirm the installation angle and greatly improve the charging efficiency; ABS+PC+anti-UV+flame retardant, private mold integrated molding, stable operation in the environment of -45℃~135℃, the material is better than the front and rear protective bars of the car, and the service life is more than 8 years; The aviation head wiring prevents misconnection, has good waterproof performance, and is quick and trouble-free to install. A new generation of N-type 10-inch wafer photovoltaic cells The maximum output is 3 amps, with short-circuit protection to avoid burning the equipment circuit due to incorrect connection of the output positive and negative during construction. After it is fully charged, recharge it after it drops to a certain level to avoid shortening the battery life due to repeated charging at high voltage. Before the battery is depleted, the output is shut down protectively, and the output is turned on only after charging reaches a safe voltage. This prevents the camera from being drained of battery power after recharging after a loss of power, causing repeated restarts and affecting the life of the battery and camera. System watchdog function, automatically restarts within 30 seconds of crash;
