Thank you for this excellent resource, I've learned a great deal from it.
There are sone typos in this sentence on page 6: "Consequently, THE A limit on the Array Isc is most likely to be a limiting factor when the Voc THE OF PV Array is at the lower end of the operating PV voltage for the controller. "
Two sentences further on: " to produce a Voc that is higher
in the controller’s safe operating range" - should that be "higher THAN"?
