3S2P query

Good evening,

my setup:

ES 2GX

RS 450/100

2X PYLONTECH US5000

CANADIAN SOLAR 410WX6

I have CANADIAN SOLAR 410WX6,can I connect 2 strings in parallel with each string having 3 panels in series for the inbuilt ES2 GX MPPT 250/70 (as it has onlt 1 tracker)? Can the positive of each string be joined together to go to the + of the MPPT controller and likewise for the 2 negative terminals of the 2 strings to go to -ve of the MPPT controller?The RS 450/100 has its own 2 strings.

Many thanks

That goes without a hitch. I have practically the same set-up with three modules per string and two strings in parallel.

Both positive poles of the strings go to PV+ and both negative poles go to PV -. Double check the correct polarity.

However, the modules of the strings should be aligned in the same way, i.e. not east/west.
