  2. Hi @Derek Ramos I have a dilemma related to the post on not needing to match panels on an mppt. i have 12 by 650W panels connected in series to an 8Kw Deye inverter. I have read that sometimes the voltage of the panels can fluctuate in winter, so i am concerned that I may exceed the max v input of 500V. If i connect them in parallel and split them into 6 each I'm worried that my solar generation will be reduced. Both my strings face north and from 11am to 4pm i get full sun on all the panels. Should i split them into 8 on one mppt array and 4 on another, would that be more efficient than a 6, 6 split or does the inverter just total whats being generated regardless of the split? I live in Gauteng, South Africa. i hope my questions makes sense. I am a newb.
