The project should work as follows:

  1. The project should charge a banks of batteries in automatic mode
  2. The microcontroller should monitor the battery voltage and current
  3. The setpoints should be set by push buttons increase or decrease
  4. The setpoints should be saved in the eeprom in case of power failure
  5. The battery voltage and current should be shown in the LCD
  6. The SCR should be fired as phase angle principle
  7. Zero crossing will be detected by the microcontroller and create interrupt
  8. In case the batteries are flat, the output current should be at maximum
  9. The SCR should be slowly changing its output as the setting is reached
  10. The SCR is connected back to back with diode and output is 48VDC
  11. There should be deviation of high and low output alarm
