20A PWM Charge Controller for 12V/24V Lithium Batteries with LCD Screen - Photovoltaic Solar Controller

Welcome to our shop! Discover our solar charge controller, your smart partner for automatic and efficient management of your solar panels and batteries. Equipped with an integrated industrial microcontroller, it ensures reliable management and is compatible with 12V and 24V systems. It features a dual USB output (5V/2.5A maximum), perfect for charging your smartphones, tablets, and PCs. Your safety and that of your equipment are paramount thanks to multiple integrated protections: against overcurrent, short circuits, reverse connections, undervoltage, and overcharging, thus extending the life of your battery. The 3-stage PWM charging technology (fast charge, bulk charge, and float charge) ensures an intelligent and highly efficient charging process. This versatile regulator is applicable in numerous fields: solar power generation systems, home automation, solar ventilation systems, solar light boxes, advertising panels, and warning lights. **Detailed Technical Specifications:** **Item Type:** Solar Charge Controller * **Supported Battery Types:** * B1: 12V/24V lead-acid battery (automatic identification) * B2: 3.7V lithium-ion battery (3 cells in series = 11.1V) * B3: 3.2V LiFePO₄ battery (4 cells in series = 12.8V) * **System Voltage :** Automatic adaptation 12V/24V* **Max PV voltage Up to 23V (12V system) / Up to 46V (24V system)* End-of-charge voltage: 14.4V (B1) / 12.6V (B2) / 14.6V (B3)* Discharge cut-off voltage: 10.7V (B1) / 9V (B2) / 10V (B3)* Discharge recovery voltage: 12.6V (B1) / 10.5V (B2) / 12V (B3)* Light control activation threshold: 8V photovoltaic panel* Light control deactivation threshold: 8V photovoltaic panel* USB output: 2 ports, 5V/2.5A (maximum)* Standby current: < 10mA* Operating temperature: -35°C to +60°C**Your order includes:*** 1 x Solar Charge Controller* 1 x User Manual in English
