What is feature of 12v / 24v pwm solar charger controllers 5v / 2a usb output ?
1. Applicable for 3 types of batteries: B01 Lead-acid battery, B02 Lithium-ion battery, B03 Lithium iron phosphate battery
2. The power-cut memory function can automatically retain users' last settings
3. Equipped with a large-screen LCD display
4. Features a complete three-phase PWM charge management system (Constant current mode, Constant voltage mode, Floating charge mode)
5. Includes multiple protections: Overcurrent protection, Short circuit protection, Open circuit protection, and Battery reverse protection
6. Utilizes a double MOS tube anti-reverse circuit protection to prevent battery current from flowing back to the solar cell at night, thus avoiding power loss
