Dual USB PWM Solar Charge Controller with ABS LCD Screen, 12V/24V 10A Regulator for 130W-260W Panels and Lighting

Welcome to our shop! Discover our K1688 dual USB solar charge controller, your reliable solution for renewable energy management. Made of robust ABS and finished in black, this controller is designed for long-lasting performance. At its heart is a high-quality industrial control chip. It ensures comprehensive three-stage charging management, incorporates a backflow resistance circuit, and generates very little heat for optimal efficiency. It features a large, clear LCD screen that displays the charging and discharging current, allows you to view the cumulative power generated and discharged, and indicates the temperature. This smart controller combines light control and a timer function. You can adjust the charging and discharging parameters to suit your needs, and it has a memory function in case of a power outage. Practical, it offers two USB outputs with a maximum current of 2.5A (5V), sufficient for quickly charging devices like the iPhone. Safety is a priority with built-in self-recovering protection against overcurrent, short circuits, open circuits, and reverse connections, thus preserving the controller's integrity. **Detailed Technical Specifications:** **Item Type:** Dual USB Solar Charge Controller** **System Voltage:** 12V/24V Automatic Adaptation** **Maximum Photovoltaic Voltage:** 50V** **USB Output:** 2 outputs, 5V/2.5A (Maximum)** **Boost Charge Voltage:** 14.4V** **Float Voltage:** 13.7V (Default Value, Adjustable)** **Discharge Cutoff Voltage:** 10.7V (Default Value, Adjustable)** **Discharge Recovery Voltage:** 12.6V (Default Value, Adjustable) (default, adjustable)* **Charge recovery voltage:** 13V* **Standby current:** <10mA* **Operating temperature:** -35°C to +60°C** **Maximum photovoltaic input power:*** **10A version:** 130W (12V system) / 260W (24V system)* **20A version:** 260W (12V system) / 520W (24V system)* **30A version:** 390W (12V system) / 780W (24V system)** **What you receive:*** 1 x Controller (Charge Regulator)* 1 x User manual in English
