August 22, 20214 yr Hi Leshen Tried to a search but difficult to get a direct find on this question. Does it make a difference in how you connect String 1 and String 2 to MPPT 1 And of course String 3 and String 4 to MPPT 2. Looking at the available spaces, you could connect String 1 and String 2 directly onto the Inverter MPPT 1 as there are 2 positive and 2 negative connections available. But would it make a difference if you first parallel string 1 and string 2 and then connect that to only 1 positive and 1 negative of MPPT 1? See below illustration (just showed the positive wires for illustration): Option 1: Direct to MPPT 1: Versus Option 2: First parallel and then connect to MPPT 1: I see the manual says the following: Therefore it seems that if there is a direct connection per string to the MPPT there may be some performance gains? Any insights on this matter will greatly assist Thanks Edited August 22, 20214 yr by branderplank
