Rapid Shutdown
When all PV modules connected to the solar inverter are ÑÊĒªñà with
optimizers, the PV system shuts down quickly and reduces the output voltage of
the PV string to below 30 V within 30 seconds. If optimizers are ÑÊĒªñà for
some PV modules, the rapid shutdown function is not supported.
Perform the following step to trigger rapid shutdown:
ɲ
Dì¯ÑǁǿfñàÊÑč the AC switch between the solar inverter and the power
grid.
ἷ
If the SUN2000 supports and enables the Ñčȝªà² function, the rapid
shutdown function is not supported.
Ἰ
ɲ
Dì¯ÑǂǿfñàÊÑč the DC switch at the bottom of the SUN2000. (If an extra
DC switch is connected to the input side of the SUN2000, turning Ñč this DC
switch will not trigger rapid shutdown.)
