Circuitry Options with Inline String Fuses
The string fuses for the SMA String-Monitor are integrated as so-called "inline string fuses" on the outside of the
enclosure in the string connection. The string terminals of the SMA String-Monitor are equipped with DC connectors
from the SUNCLIX product range of Phoenix Contact. Suitable for the SUNCLIX plug-in system, inline fuse connectors
(see Section 2.2, page 6) and Y adapters are available from SMA Solar Technology AG as accessories (see
Section 8, page 24).
The string terminals are located outside of the enclosure of the SMA String-Monitor. This offers several options for the
circuitry and fuse protection of the strings.
