Hi folks,
Im having a problem that I was hoping to get some help with.
I have a 96V solar array, in which the battery is divided in two banks with a center point (+48,0,-48)
I need to measure when an imbalance has occurred and for that I need to measure the individual banks. My CPU ground is connected to the 0V supply. I am not sure how to measure the bottom bank as the voltage is negative in respect to the CPU GND.
Note: Both banks need to be measured at the same time, trough a simultaneous sampling ADC, so that rules out most external SPI ADC's.
Any suggestions on this?
Many thanks
