Hi guys. I am designing a PCB for a solar array. The array is composed of 24, Vmp=35.2, Imp=4.95 panels. They are connected such that there are 8 strings in parallel and each string has 3 panels in series. Therefore, each string is going to have a maximum current of around 5A, and the voltage across the two nodes is about 105V. My PCB is going to have 8 ACS715 Hall effect current sensor ic to measure the current before the strings combined, and a 0.25w rated 1megaohms/47kohm voltage divider with a 1w 4.7V zener diode for over voltage protection which will feed to an A/DC for voltage measurement. Considering this is a 4000W system, is there anything specific that I should paid attention to? Thanks.
