Note: This Solar Charge Controller has a unique feature that will allow it to restart a lead-acid battery pack.

Warning: These Charge Controllers CANNOT operate in parallel.

For parallel operations see model ML4860.

These solar charge controllers have a Bluetooth function included to monitor the working status of the controller and its whole system. The BT-1 and BT-2 Bluetooth adapter is used to extend Bluetooth communication function of the Bluetooth module. Mobile phone app can be used for wireless monitoring, parameters setting, and data view.


·        Advanced double-peak or multiple-peak tracking technology.

·        Built-in algorithm for maximum power tracking to raise energy utilization efficiency of photovoltaic systems.

·        Charging efficiency 15%-20% higher than traditional PWM solar charge controllers.

·        Combination of multiple tracking algorithms that can track the optimum working point of I-V curve accurately in a very short period of time.

·        MPPT efficiency can be as high as 99.9%

·        Advanced digital power technology, with circuit energy conversion efficiency as high as 98%.

·        Current-limiting charging mode. When the power of a solar panel is too large, and the charging current is greater than rated current, the solar charge controller automatically reduces charging power, thereby making the solar panel work at rated charging current.

·        Automatic identification of battery voltage.

·        LED indicator, buzzer alarm, and liquid crystal display to help users identify system failures.

·        Supports data storage for up to five years.

·        LCD screen display to enable users to view equipment operation data and status and modify controller parameters at the same time.

·        Standard Modbus protocol that meets communication needs on different occasions.

·        Built-in mechanism for over-temperature protection. When the temperature exceeds the preset value, the charging current falls linearly with temperature, therefore slowing down the rise of controller temperature and avoiding controller damage from high temperatures.

·        External battery voltage sampling function to prevent line loss from affecting external battery voltage sampling and to ensure greater preciseness of control parameters.

·        Temperature compensation functions to automatically adjust charging and discharging parameters to extend battery service life.

·        Many protection functions.

·        TVS lightning protection.
