12V/24V/48V 30A PWM Solar Charge Controller with RS232

The main features:

1. Using MCU and special software, based on the special software of the expert control system, realizes the intelligent optimization SOC control.

2. The temperature compensation adopt external temperature sensor, the control accuracy is higher than the internal temperature sensor.

3. Have the overcharge, discharge, electronic short-circuit, overload protection, unique counter-attack joint protection automatic control; Above the protection are not causing damage to any component, and don't burn the fuse.

4. Adopt the tandem PWM for charging main circuit, make the charging loop voltage is reduce nearly half than use the diode charging circuit. The charging efficiency is higher 3%~6% than the non-PWM, increased the power of time. Enhance the charge of over-discharge recovery, normal direct charge, the float-charge automatically controlled way can make the system has a longer use life.

5. The intuitive LED iuminotron indicates the current battery status, allow users to understand the situation of use.

6. The all control adopt the technical grade chip, can run freely in cold, high temperature, damp environment. At the same time use the crystal oscillator timing control, precise timing control.

7. Using the digital LED display and Settings, a key type operation can complete all Settings, use is very convenient for intuitive.
