Does anybody know the spec for SunnyBoy TL inverters inbuilt current protection? According to SMA "The inverter is equipped with an integrated all-pole sensitive failure current monitoring unit" but I can't find any detailed spec, does it effectively work as an RCD? if so what trigger current and what disconnection time? I get the impression it is protection for severe faults and disconnection times are 5 sec as G83 but can't find the details written down anywhere.
Any help would be appreciated
