D Rapid Shutdown
When all PV modules connected to the solar inverter are congured 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
congured for
some PV modules, the rapid shutdown function is not supported.
Perform the following step to trigger rapid shutdown:
● Method 1: Use the rapid shutdown function. Set Dry contact function to DI
Rapid Shutdown. Connect the access switch to pins 7 and 5 of the inverter
communications terminal. The switch is turned
o by default. When the
switch is turned on, rapid shutdown is triggered.
● Method 2: Turn o the AC switch between the solar inverter and the power
grid.(If the SUN2000 supports and enables the
o-grid function, the rapid
shutdown function is not supported.)
● Method 3: Turn
o the DC switch at the bottom of the SUN2000. (If an extra
DC switch is connected to the input side of the SUN2000, turning o this DC
switch will not trigger rapid shutdown.)
● Method 4: If AFCI is enabled, the inverter automatically detects arc faults,
triggering a rapid shutdown.
