I used the MPPT calculator for a 3S2P configuration of 380W panels, and it calculates a MPPT 150/35.
The 35A of the MPPT seems a bit on the low side (6x380W=2280W /57.6=39,58A).
Also the solar system will be in Thailand, and i want the equipment as cool as possible.
Will there be a pro’s/cons if I buy a MPPT 150/45 so the SCC doesn’t have to work at its limit?
I have very similiar panels in North QLD australia. I have 2 strings over 2 MPPTs.
40.8Vmpp x 9.56Imp x 7 = 2730W. String Vmpp theory should be 285V. It will depend on the panel’s performance. If you get budget ones you might not even get close when they heat up I have 390W Hyundai Shingled.
