PV array

:    Provides DC power to the SPH inverter. A DC   

Disconnect  Switch  or  optional  Solar  Concentrator  is  usually 
fitted between the PV array and the SPH inverter.   

 

SPH inverter

:  Converts DC power from the PV array into AC power. The AC 

(Alternating Current) power is supplied to the electric grid (AC 
utility).  The  SPH  inverter  uses  Maximum  Peak  Power  Tracking 
(MPPT)  to  optimize  the  PV  array  operation  and  deliver 
maximum power to the electric grid.   

 

Connection

: The “interface” between the SPH inverter and the   

System 

Grid  usually  consists  of  an  electrical  breaker  or  fuse  and 
terminals  for  connection.  It  may  also  contain  a  disconnect 
switch.  For  proper  safety,  this  part  must  be  designed  by  a 
qualified electrician or electrical installation technician.         

 

Utility

The electricity supply from the main electric grid 

                          system must be single phase 220V to 250V, 50Hz 
                          or 60Hz.
