Tracer-BP Solar Charge Controller 20A By Epever


Tracer 5210BP 20A MPPT Lithium Battery MPPT Solar Charge Controller 12/24V Epsolar


Tracer-BP Solar Charge Controller adopts advanced MPPT (Maximum Power Point Tracking) charging methods, resulting in up to 30% charging efficiency increase compared with the PWM charge controllers. The RS485 interface with standard MODBUS communication protocol and 5V,150mA power supply makes it easy for the customer to expand the application. With the accessories like MT50, WiFi module, Bluetooth adapter, IoT module, users can realize remote monitoring and controlling the solar system via app and cloud platform.
