Features

1、Use CPU processor superior speed performance.
2、The high precision A/D sampling to ensure the accuracy of sampling.
3、The efficient tandem PWM charging mode, extend battery life, improves the system performance.
4、The controller with over temperature, over discharge, overload, short circuit protection function.
5、Radiator heat dissipation is fanless designed and fanless design. Dust is difficult to enter, sealed well, with sufficient material, no suction, low power consumption, effectively avoiding noise.
6、The photovoltaic array and reverse battery protection function.
7、Standard RJ45 interface equipment that can be used for connecting the liquid crystal display unit or PC monitor software and communication peripherals, it is convenient for the user view the controller’s running data, modify the controller control parameters.
8、Use of RS-232 communication, the communication speed and communication protocol compatibility are very well.
