MPPT solar charge controller could detect the generation power of the solar panel in real time and track the highest voltage and current value (VI), allowing the system to charge the battery with maximum power output. It is used in the solar off-grid photovoltaic system to coordinate the work of solar panels, batteries and loads. It is the core control component of off-grid photovoltaic systems.

Advanced dual-wave peak or multi-wave peak tracking technology, when the panel is covered by shadows or part of the panel is damaged, multiple wave peaks will appear on the I-V curve, and the controller can still accurately track the maximum power point.
The built-in maximum power tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, which is about 15%-20% higher than traditional PWM charging efficiency.
The combination of multiple tracking algorithms can accurately track the best working point of the I-V curve in a very short time.
MPPT tracking efficiency up to 99.9%.
Using advanced digital power technology, the circuit energy conversion efficiency is up to 98%.
Support charging program of various types of batteries including gel battery, sealed battery, open battery and lithium battery.
With current-limiting charging mode, when the battery board power is too large and the charging current is greater than the rated current, the controller automatically reduces the charging power to make it work at the rated charging current.
Support instantaneous high-current startup of capacitive loads.
Support battery voltage automatic identification.
With fault LED indication and LCD display abnormal information, it is convenient for users to determine system failure.
Support historical data storage for up to 1 year.
With LCD screen display function, you can view equipment operating data and status, and support the change of controller parameters.
Support standard modebus protocol to meet the communication needs of different occasions.
Built-in over-temperature protection mechanism, when the temperature exceeds the set value of the device, the charging current decreases linearly with the temperature, thereby reducing the temperature rise of the controller and avoiding the controller's high temperature damage.
With temperature compensation function, automatically adjust the charge and discharge parameters to improve battery life.
With TVS lightning protection.
