12V 24V 48V Solar Charger Controller PWM

12V 24V/48V 10A/20A/30A Solar Charger Controller PWM Solar Controller Manual PWM Solar Charge Controller

PWM solar controller refers to the use of the digital output of the microprocessor to control the analog circuit, which is a method of digitally encoding the analog signal level. Controlling analog circuits digitally can greatly reduce the cost and power consumption of the system. A PWM controller is included in many microcontrollers.

   The basic principle of PWM solar charge controller: When the narrow pulses with the same impulse and different shapes are applied to the link with inertia, the effect is the same. The PWM solar control principle is to divide the waveform into 6 equal parts, which can be replaced by 6 square waves equivalently. There are many classification methods of pulse width modulation, such as unipolar and bipolar, synchronous and asynchronous, rectangular wave modulation and sine wave modulation.

Ten main functions:

1. Overvoltage  protection

2. Undervoltage  protection

3. Over  power  protection

4. Short  circuit  protection

5. AC input  undervoltage protection

6. PG circuit

7. Remote power-on signal

8. Power-on signal and PG signal delay

9. Two bypass regulators TL431 to stabilize 3.3V and 5V independent power supply

10. Soft start and maximum 93% duty cycle
