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
