2.5 DC Switch
The DC switch can safely disconnect the inverter from the PV strings. The inverter is equipped
with one auxiliary switch and three DC switches. Three DC switches are used for controlling
the PV terminals in three different areas respectively. Upon detecting reverse polarity, back-
feeding, or a fault inside the inverter, the DC switch will turn off automatically to interrupt the
DC input.
In case the DC switch on the inverter turns off by itself, please proceed by referring to 8.2.6
DC Switch Maintenance.
