Most often, the implementation of string monitoring engineered in a combiner box is too expensive. We go out to solar sites with a non-intrusive method that uses a datalogger and clamp-on current transformers. Over the course of a few days, we get a great apples-to-apples comparison of current that comes from one string to the next during a consistent voltage window.
