The WELLSEE WS-C2425 (15A, 20A, 25A) Solar Charge Controller applies in solar photovoltaic systems, which coordinates the working of solar panels, batteries and loads. It adds some protection functions, so that the entire system can be operated efficiently and safely.

WS-C series charge controllers apply to all types of photoelectric panels and various types of batteries, MCU (Micro-Processing Controller) has PMW (Pulse Modulation Wide-frequency) 0~100% variable duty cycle process. According to the types and actual charging situation of the battery, WS-C controller series can provide the fast and best charging voltage and electricity from the PV panel. C25 and C50 series are equipped with advanced man-machine interactive function, so the user can adjust the charging voltage.
