industrialisation standard. Multi-synchronous rectification technology ensures extremely high conversion efficiency under any charging power environment, which greatly improves the energy utilisation of the solar system; advanced MPPT control algorithm is also adopted.

Advanced MPPT control algorithm minimises the maximum power point loss rate and loss time, ensuring maximum power point tracking efficiency, response speed and high power conversion efficiency in small and large power bands.

Advanced MPPT control algorithm minimises the maximum power point loss rate and loss time, ensuring the maximum power point tracking efficiency, response speed and high power conversion efficiency in both large and small power segments, which can quickly track to the maximum power point of the PV array and obtain the maximum energy of the solar panels under any environment.

The maximum power of the solar panel can be quickly tracked in any environment. It operates at rated power in the full working temperature range and has the function of automatic power reduction for over-temperature charging; it has the function of double automatic limitation of rated charging current and power, which fully ensures that the product can be used in the full range of temperature and temperature.

It has double automatic limiting function of rated charging current and power, which fully ensures the system stability of the product in over-temperature operation and access to excess PV modules as well as under high temperature operation. The LCD screen dynamically displays the operation status,

The LCD screen dynamically displays the operation status, operation parameters, controller log, control parameters and so on. With over-charging, PV connection and other protection functions, effectively ensure that the solar power supply system is safer, more stable and more

Long-term operation

Performance characteristics

 Adaptive three-stage charging mode controlled by digital circuits, effectively prolonging battery life and improving system performance.

 Excellent MPPT high power point tracking technology, tracking efficiency not less than 99.5%.

 Unique circuit design provides high DC/DC conversion efficiency in both high and low power bands, up to 98.5% and 97% full load efficiency.

 Advanced MPPT control algorithms ensure that the maximum power point loss rate and loss time are minimised.

 Accurate identification and tracking of multi-peak maximum power points.

 Dual automatic limiting function of rated charging power & charging current.

 Provide multiple battery types, support maintenance-free, gel, liquid, lithium and other battery types charging.

 With settable battery temperature compensation function.

 With real-time power statistics and recording function.

 With high temperature charging automatic power reduction function. Built-in over-temperature protection mechanism ensures that when the temperature exceeds the set value of the device, the charging current decreases linearly with the temperature, thus reducing the temperature rise of the controller and avoiding high temperature.

This reduces the temperature rise of the controller and avoids high temperature damage.

 With the photovoltaic panel input reverse connection and battery reverse connection protection function.

Various sampling data are visualised on the screen for easy access.

 Maximum input PV voltage 150V, a wider range of maximum power point operating voltage, improve the utilisation rate of PV modules, applicable to a variety of commonly used solar panel specifications.

 Ultra-low power consumption power supply chip, reduce static standby energy consumption, reduce energy loss at night.
