Anern’s MSC is a multi-level maximum power point tracking (MPPT) photovoltaic battery charge controller with independent technology. Compared with PWM controller, MPPT can improve the control accuracy and increase the output power of solar panels. It has the characteristics of high efficiency, stability, and safety, and can provide users with reliable energy supply. It is widely used in solar power supply systems such as homes, schools, streets, stations, and power stations.
