Working Principle    

                    
1: PV Charges DC CAP with its maximum power and DC-DC booster work with +/- 390Vdc, if load power        

     is bigger than PV power, the DC CAP voltage will drop and DC-DC booster output voltage will decrease        
     too, AC-DC booster works with +/-360Vdc, thus it will share the load power automatically between PV          
     AC. So the DC CAP voltage will reach to a stable value. Battery SCR Q1 stops if line voltage is normal          
2: If PV power is bigger than load power, MPPT charger autoatically charges the battery. MPPT charger       
     works in fload voltage mode, MPPT mode if battery voltage and DC CAP Voltage are high.                        
3: If AC loose, stop AC-DC booster, switch on batter SCR Q1, make battery and PV works together to             
     power for the load.                        
4:  If both PV and AC not there, battery works to power the load as the last option.                        
                        
Absolute advantages            

            
1: No affexted by nation power regulartion policy                        
2: Ouput voltage is stable. Zero transfer time between line mode and battery mode.                        
3: Battery works in normal situation, not frequently discharged and the life time is extended max long.                        
4: UPS works even in very low AC voltage when PV is also in picture together sharing the load.
