This PWM solar charge controller provides efficient, reliable charging and system protection for off grid solar installations. Key benefits charging efficiency: PWM automatic tracking charging optimizes power transfer from solar panels to batteries, improving charge efficiency and reducing wasted energy. System protection and reliability: Built in protections for overheating, overcurrent, short circuit, open circuit, reverse connection, and overload keep batteries and connected equipment safe. The controller also performs troubleshooting and automatic recovery after faults. Reduced heat and stable performance: Dual way MOS tube anti backflow circuit minimizes heat generation and prevents reverse current flow from batteries to panels, preserving battery charge and extending component life. Clear monitoring and control: Large screen LCD displays system status and key parameters, making it easy to monitor voltage, current, and fault conditions. Function and compatibility Function: PWM charging controller with automatic panel tracking, anti backflow protection, fault detection, and automatic recovery. Compatibility: Designed for use with standard photovoltaic panels and battery banks in small to medium off grid systems. Suitable for common solar lighting, battery charging, and DC load applications. Performance: Built in protections and dual MOS design improve conversion stability and reduce thermal stress during operation. Practical applications Remote cabin or cottage: Maintain battery banks and run lighting and small appliances while protecting batteries from overcharge and reverse discharge. Recreational vehicle or boat: Keep house batteries charged reliably while at anchor or parked, with clear LCD status and automatic fault recovery. Remote monitoring or equipment sites: Provide dependable charge control for telemetry, sensors, or communications equipment where maintenance visits are limited. What sets it apart Combines PWM automatic tracking with dual way MOS anti backflow circuitry for efficient charging and low heat generation. Multiple built in protections and automatic controller recovery reduce the need for manual intervention. Large screen LCD provides clear, actionable information for faster troubleshooting and system oversight. This controller is intended for integration with solar panel arrays and battery systems to enhance charging efficiency and safeguard components in a variety of off grid applications.
