EPever MPPT 40A/30A/20A/10A Solar Charge Controller Black-Light LCD Solar Regulator for 12V 24V Lead Acid Lithium-ion Batteries



The Tracer AN series. Based on common negative design and advanced MPPT control algorithm, with LCD displaying running status, this product is artistic, economical and practical. Improving the MPPT control algorithm further, Tracer AN series can minimize the maximum power point loss rate and loss time, quickly track the maximum power point of the PV array and obtain the maximum energy from solar modules under any conditions; and can increase the ratio of energy utilization in the solar system by 10%-30% compared with a PWM charging method. The limitation function of the charging power and current and reducingcharging power function automatic improve the stability which works even connecting oversize PV modules and in high temperature, and increase the professional protection chip for the communication port, further improving the reliability and meeting the different application requirements.

Accessories (optional):


​Remote Temperature Sensor



Acquisition of battery temperature for undertaking temperature compensation of

controlparameters, the standard length of the cable is 3m (length can be

customized). The RTS300R47K3.81A connects to the port (4th) on the controller.

NOTE: The temperature sensor short-circuited or damaged, the controller

will be charging or discharging at the default temperature 25°C 


USB to RS485 cable 



USB to RS-485 converter is used to monitor each controller on the network

using Solar Station PC software. The length of cable is 1.5m.

TheCC-USB-RS485-150U connects to the RS-485 Port on the controller.


OTG cable



Used to connect a mobile communication cable and able to achieve real-time

monitoring of the controller and modification of the parameters by using mobile

APP software.


Remote Meter



MT50 can display various operating data and fault of the system. The

information can be displayed on a backlit LCD screen, the buttons are

easy-to-operate, and the numeric display is readable.


WIFI Serial Adapter 



After the controller is connected with the eBox-WIFI-01 through the standard

Ethernet cable (parallel cable), the operating status and related parameters of

the controller can be monitored by the mobile APP software through WIFI signals.


RS485 to Bluetooth Adapter



After the controller is connected with the eBox-BLE-01 through the standard

Ethernet cable (parallel cable), the operating status and related parameters of

the controller can be monitored by the mobile APP software through Bluetooth
