Hi,
 
	I have one 200KW inverter with 12 MPPT and a load limit of 200KW at the inverter level. The DC capacity is 311.04 kWp, and I have a total of 16 strings, with 36 modules per string, each rated at 540Wp.
 
	In both cases, when running PVsyst:
 
	Case 1: If I run PVsyst on one inverter with 16 strings, the result is PR (Performance Ratio).
 
	Case 2: If I run PVsyst with 12 MPPTs and 16 strings, the result for PR differs. (4 MPPTs with 2 strings and 8 MPPTs with 1 string)
 
	In both cases, PR varies , and inverter losses over nominal inverter power loss are high in case 2.
 
	 
 
	which case is correct
