D Rapid Shutdown
If all PV modules are equipped with optimizers, the PV system can perform a rapid
shutdown, reducing the output voltage of the optimizers to below 30 V within 30s.
The rapid shutdown is not supported if optimizers are
congured for some PV
modules.
Triggering methods of rapid shutdown:
● Method 1 (recommended): Turn
o the AC switch between the inverter and
the power grid.
● Method 2: Turn
o the DC switch at the bottom of the inverter.
● Method 3: If the DIN5 port (port 15) of the inverter communications terminal
is connected to a rapid shutdown button, press the button to trigger rapid
shutdown.

Log in to the FusionSolar App as an installer, choose Me > Device Commissioning,
and connect to the WLAN hotspot of the SUN2000. Log in to the local commissioning
system as an installer user, choose Settings > Feature parameters > Dry contact
function, and set Dry contact function to DI rapid shutdown.
● Method 4: If AFCI is enabled, the inverter automatically detects arc faults,
triggering a rapid shutdown.
