String alarms reflect outages of single strings of a string combiner box or of inputs for string inverters. In this example, when at least one string of the string combiner box measures more than 10% of its nominal current during the daytime, the other strings are considered outages when they measure no current.
For systems equipped with string combiner boxes, if all strings of one combiner box are outages, all the string alarms are grouped into a single string alarm. This minimizes the overall number of alarms and creates maximum transparency for the user. You can also set the severity and delay.
