Feature: 1. AUTOMATIC MANAGEMENT: This solar charge controller helps you automatically manage your solar panels and batteries with a built in industrial microcontroller. You can also charge cell phones, tablets, personal computers with dual USB output 5V 2.5A( maximum). 2. THREE STAGE PWM REGULATED CHARGING: Adopting three phase PWM regulated charging for fast, large and float charging, it realizes efficient and fast intelligent charging through the controller, which effectively prolongs the service life of the battery. 3. SAFE TO USE: Overload and overcurrent protecting, short circuit protecting, reverse connection protecting, low voltage, overcharge protecting, 3 level PWM charging management. This solar charge controller will help you safely improve system efficiency and extend battery life. 4. WIDE APPLICATION: Suitable for solar power system, smart home, solar charger, solar ventilation system solar light box, solar billboard, solar warning light, etc. Compatible with 12V 24V system. 5. EXTREMELY LOW SELF CONSUMPTION: Has extremely low self consumption characteristics, making it an energy efficient and practical solution for off grid power systems. Due to the low self consumption rate, the charge controller consumes very little battery power, allowing you to maximize the efficiency and service life of your power system.
