Mix and match panels
I have 4 KC 170 panels connected to form a 48v system. I am now going to add 4 KC 175 panels for a second 48V string. Was told by the retailer that mixing the 2 sizes would not cause any issues. Wondering if it would not be better to use 2 of each in a 48v string or let the MX60 sort out the difference between the 4x175 and the 4x170 string.
