Solar Battery Controller 12V/24V PWM Negative Ground Solar Panel Controller Regulator with Adjustable LCD Display and Dual USB Ports Timer Setting PWM Auto Parameter (Single Channel, 60A) Why this controller matters Keeps your solar charging system stable and predictable by managing charging and load output with PWM control. Protects battery life by preventing overcharge and supporting controlled discharge through programmable timer and output controls. Makes system monitoring and adjustments simple with an adjustable LCD display and userfriendly settings. Key benefits and problem solving Reliable charge regulation: 60A PWM charging provides steady, efficient current suitable for medium to large 12V or 24V battery systems. Auto detection switches between 12V and 24V to match the battery bank automatically. Easy monitoring and control: Adjustable LCD displays realtime voltage, current, and system status so you can verify performance and change settings without extra tools. Flexible load scheduling: Builtin timer setting lets you automate lighting or appliance loads, saving battery power and removing the need for separate timers. Direct device charging: Dual USB ports provide convenient 5V outputs to charge phones, tablets, and USBpowered devices from the battery system. System compatibility: Designed for negative ground systems to match common wiring standards and simplify installation. Primary features Voltage support: Auto 12V and 24V detection and operation. Current rating: 60A continuous rating for charging and load control (single channel). Charging method: PWM regulation for controlled, lowstress charging. Ground type: Negative ground design. Interface: Adjustable LCD display for status, parameters, and easy configuration. Ports: Dual USB outputs for device charging. Control: Timer setting for load on/off scheduling and energy management. Auto parameter function: Automatically optimizes charging parameters for consistent operation. Typical applications Offgrid cabin or workshop: Manage panel charging, schedule lighting with the timer, and keep phones and small devices charged through builtin USB ports. Recreational vehicle or boat: Use the controller to maintain battery health while powering lights and accessories and to provide convenient USB charging for passengers. Small commercial or remote lighting systems: Control timed lighting, monitor system performance via the LCD, and protect battery banks with PWM regulation. Installation and compatibility notes Suitable for DC solar systems configured as negative ground. Auto 12V and 24V selection requires correct battery connection for detection. Follow standard wiring practice for solar panel, battery, and load connections; ensure the controller is rated appropriately for system current and panel output.
