Step 1: Mppt Detecting Solar.

if (((Panel_Voltage > Battery_Voltage + 40) && (Panel_Voltage < 3000))&&(!Start_Delay)&&(Battery_Voltage > 850))// && (GUI_Battery_Charge_Current_State))
{ if(!Reading_Captured) { Duty = (((Battery_Voltage * 10) / (Panel_Voltage / 10)) + 10)*6.80; Reading_Captured = 1;

• PANEL_ENABLE ; // Activate Relay ; PWM_ENABLE ; delay_ms(500) ; // Wait for relay To Latch .. Pwm_Phase_shifts() ; // Start pulse

}
