I'd like to see if anyone can recommend a solution for string-level AFCI. What I need is a device that does the 690.11 arc fault feature, but does not combine the strings.
I have a project that uses the European version of SMA Sunny Tripower inverters, which do not allow you to "pre-parallel" your strings in advance of connecting to the inverter, and does not already contain AFCI, which the project requires.
