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 off by default. When the
switch is turned on, rapid shutdown is triggered.
Method 2: Turn off the AC switch between the solar inverter and the power
grid.(If the SUN2000 supports and enables the off-grid function, the rapid
shutdown function is not supported.)
Method 3: Turn off the DC switch at the bottom of the SUN2000. (If an extra
DC switch is connected to the input side of the SUN2000, turning off this DC
switch will not trigger rapid shutdown.)
Method 4: If AFCI is enabled, the inverter automatically detects arc faults,
triggering a rapid shutdown.
