Product features:
1.Thanks to advanced dual or multiple peak tracking technology, when the battery panel is shaded or partially damaged, multiple peaks will appear on the IV curve, and the controller can still accurately track the maximum power point.
2.The integrated maximum power tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, which is approximately 25% higher than traditional PWM charging efficiency.
3.The combination of multiple tracking algorithms allows for accurate tracking of the optimal operating point on the IV curve in a very short time.
4.MPPT tracking efficiency can reach up to 99.9%.
5.By adopting advanced digital power supply technology, the circuit's energy conversion efficiency can reach up to 98%.
6.Supports charging programs for various battery types, such as gel batteries, sealed batteries, open-cell batteries, and lithium batteries.
7.Equipped with a current-limiting charging mode, when the battery board's power is too high and the charging current exceeds the rated current, the controller automatically reduces the charging power to operate at the rated charging current.It can support instant high-current starting of capacitive loads.
8.Supports automatic battery voltage identification.
9.With a fault LCD screen, it is convenient for users to identify system faults.
10.Built-in overheat protection mechanism: When the temperature exceeds the device's set value, the charging current decreases linearly with the temperature, thus reducing the controller's temperature rise and preventing damage caused by high temperatures.
11.Equipped with a temperature compensation function, it can automatically adjust the charging and discharging parameters to improve battery life.
12.Comprehensive electronic protection functions.
13.Adopts a metal casing for better heat dissipation performance.
14.0V lithium battery charging function.
15.The high input voltage withstand capability of solar panels can reduce the specifications of solar wiring and lower system costs.
