60A Solar Charge Controller with MPPT and 3level PWM Charging Management Overview This 60A solar charge controller provides reliable battery charging and system protection for offgrid solar systems. It combines innovative MPPT detection of maximum charging current with full 3level PWM charging management to improve charging efficiency and extend battery life. Automatic 12V and 24V adaptation makes the controller suitable for leadacid and lithium battery systems. Key benefits Keeps battery at fill voltage to maximize state of charge and longevity Prevents overcharging, overdischarging, and reverse charging to solar panels at night Protects the system from reverse polarity on battery and solar panel connections Automatically stops and restarts loads based on battery voltage to prevent deep discharge tracking efficiency up to 99 percent through MPPT detection of maximum charging current Builtin monitoring and multiple protections reduce maintenance and system downtime Main functions Maintain battery at fill voltage condition for consistent performance Prevent battery overcharging and overdischarging Block reverse charging to solar panels during night hours Reverse polarity protection for battery and for solar panels Automatic load cutoff when battery voltage is low and automatic restart when voltage recovers Thunder protection for transient events Automatic setting of chargeoff, loadoff, and loadrestore voltages based on battery voltage grade; default parameters apply at 25 degrees Celsius and are locked by the controller CPU Automatic temperature compensation of charging voltage according to ambient temperature changes Features and performance Automatic 12V and 24V adaptation, compatible with leadacid and lithium battery chemistries MPPT technology that detects the maximum charging current rather than relying on boost type or solar panel voltage, achieving up to 99 percent tracking efficiency Full 3level PWM charging management to optimize charge stages and extend battery life Wide range of protections including shortcircuit, opencircuit, reverse connection, overload, overtemperature, and load overcurrent Overheat protection that automatically stops charging if needed and limits maximum charging current to protect circuitry Silent operation with continuous temperature monitoring Builtin backlight LCD screen for realtime monitoring and control: charging current, generated energy, temperature, battery voltage, and error codes; settings and debugging are fast and straightforward Recommended connection : battery first, then solar panel, and finally load Practical applications Offgrid cabin or tiny house: maintain battery health and prevent nighttime reverse discharge while monitoring system status on the builtin LCD Recreational vehicle and marine systems: automatic 12V/24V adaptation and comprehensive protections simplify installation and safeguard battery banks Remote equipment sites and telecom power backup: MPPT detection and temperature compensation support reliable charging and long battery life in variable climates What you get A 60A charge controller engineered for reliable battery charging, advanced MPPT detection, and comprehensive protection features Clear system status and diagnostics via backlight LCD for easy setup and troubleshooting Technical note Default voltage parameters are set at 25 degrees Celsius and are locked by the CPU procedure; the controller performs automatic temperature compensation for charging voltage during ambient temperature changes. This controller is intended for solar charging systems that require robust protection, efficient charging through MPPT and PWM management, and straightforward monitoring and control.
