Hello everyone! I'm looking into a solar array for may campervan and I'm trying to understand the capacity of the smartsolar 75/15 Vs 100/20. I would like to install mounted orizontal on my rooftop 3x 430w (Vop 38,30 Impp 13,52 Isc 14,29) panels each with a dedicated mppt to charge a 560Ah 12v lifepo4 battery bank.
Now my question is should I go with 3x 100/20 or am I good enough with 3x 75/15? It's my understanding that under 75v of open circuit I should be ok, right?
