Hi,
I have a 15kW inverter with two MPPTs, one (MPPT1) with two string input paths and the other one (MPPT2) with one string input path.
To this, I have two strings of 415W shingled solar panels (Voc 46.7V, Vmp 38.9V), one string with 15 panels facing NE and the other one with 18 panels facing SW.
The inverter's "sweet spot" is 450V-850V per MPPT (not per string input).
Would you connect both strings to MPPT1 or one string to MPPT1 and one string to MPPT2?
Please elaborate why, so that I can learn something new.
Thanks!
