Product overview This solar charge controller provides MPPT charging, reverse polarity protection, automatic load cutoff for low battery, temperature compensated charging, and multiple built in protections. It is designed to keep battery systems healthy, improve charging efficiency, and protect connected loads and equipment. Key benefits Protects the battery and connected loads by automatically disconnecting the load when battery voltage is low and restoring it when the battery recovers. Charging resumes automatically when conditions to normal. Prevents damage from incorrect wiring with reverse polarity protection for solar panel input and battery connection. Improves charging efficiency with MPPT tracking and two way focus tracking for continuous optimization during charging. Extends battery life with full three stage charging management and temperature compensated charging that adjusts charge parameters as ambient temperature changes. Reduces heat and energy loss through a bi directional MoS tube anti backflow circuit and power charging mode with ultra low heat generation. Provides clear monitoring and control via a large LCD display that shows temperature, charging current, discharge current and other real time data. Functions and protections Reverse polarity protection for solar panels and battery connections. Automatic low battery load cutoff and automatic load restore when battery condition returns to normal. Automatic temperature compensated charging to adjust charging according to ambient temperature. Lightning surge protection and other surge related protection functions. Built in protections for overheating, over current, short circuit, open circuit and reverse connection. The controller automatically recovers when faults are resolved and does not damage the device. According to battery level, the controller can automatically set load disconnect and load restore thresholds. Default parameter is 25. Some settings may be locked by the CPU and cannot be adjusted. Performance and features Industrial grade master chip with 16 AD sampling accuracy for precise measurements of temperature, charging current and discharge current. Real time display of charging current and discharge current so generation and use are visible at a glance. MPPT charging tracking with autofocus and continuous two way focus tracking for higher charging efficiency under varying conditions. Large LCD display with adjustable charging and discharging parameters. Wide and adjustable load and discharge settings allow matching to battery characteristics. Full three stage charging management to protect and prolong battery life. Bi directional MoS tube anti backflow circuit for efficient power charging and reduced heat. Convenient DC connections for solar input and lamp output as provided by the product design. What it prevents and maintains Keeps the battery charged and prevents chronic under charge. Prevents overcharging and protects battery health. Prevents over discharging and load related damage. Prevents reverse charging of the battery back to solar panels at night to improve conversion efficiency. Compatibility and use Designed for use with solar panels and battery systems in off grid and small scale grid independent installations. Intended for applications that require reliable charge control, battery protection and load management. Typical applications Off grid home lighting and power systems where battery protection and efficient solar charging are required. RV and boat solar systems for battery management, load control and charging optimization. Remote cabins, kiosks or telecom installations that need reliable charging, low battery load cutoff and automatic recovery. User controls and adjustability Charging and discharging parameters are adjustable through the LCD interface to match battery type and characteristics. Note that some parameters may be locked by the CPU and are not adjustable. Load output timing can be adjusted for convenience when outputs are switched off. This controller combines MPPT efficiency, precise monitoring, temperature compensation and multiple hardware protections to deliver reliable battery charging and load management for solar powered systems.
