Connectors of PV string cabels
Ensure that cables of the proper type are being used to connect the inverter to the PV gener-
ator. In particular, PVC and H07RN-F non-tinned cables are NOT recommended.
The PV cables must be terminated with the Amphenol H4 (MC4 compatible) provided with
the inverter.
If different types of connectors are used, or if different installation tools and procedures are
used, then it may not be possible to ensure safety and technical performance.
The 25/28/30 SHT units have integrated 15 A string fuses. The string fuses prevent too high
reverse current.
The following Connectors are recommended for PV strings:
■
Positive pole connector (+), female: Amphenol H4CFC4 S
PC
Insulation layer
Locking nut
