12KW 3Phase mixed panels
I have the 12kw 3phase inverter.
My current pannel configs are:
Mppt1-S1: 8 x 660w Trina with config-> Vmpp=37.8; Impp=17.47A; VOC=45.7v; ISC=18.53
Mppt2: 4 x 550w Canadian Solar with config-> Vmpp=41.5; Impp=13.2A; VOC=49.6v; ISC=14.0
I want to add additional panels (6 additional) from Jinko Solar. My question is can I add this to MPPT2 with a combiner box as the spec is slightly different or can I add this to MPPT1-String2?
The Jinko configs are:
6 x 550w Jinka solar with config-> Vmpp=40.9; Impp=13.45A; VOC=49.62v; ISC=14.03A
All the stats for the panels are noted at STC.
Thanks

Your best option is adding the panels in series to mppt2 (closest Impp).
Otherwise you will end up with 2 different MPP's on the 1st string and leave a lot of power.
