Restart the inverter only after removing the fault that impairs safety performance.
As the inverter contains no component parts that can be maintained, never open
the enclosure, or replace any internal components.
To avoid the risk of electric shock, do not perform any other maintenance opera-
tions beyond this manual. If necessary, contact your distributor first. If the problem
persists, contact SUNGROW. Otherwise, the losses caused is not covered by the
warranty.
Touching the PCB or other static sensitive components may cause damage to the
device.
• Do not touch the circuit board unnecessarily.
• Observe the regulations to protect against electrostatic and wear an anti-static
wrist strap.
9.2.2 Quick Shutdown
The PV system can perform a quick shutdown, reducing the output voltage of strings to be-
low 30 V within 20s.
Triggering methods of quick shutdown:
• Method 1: Turn off the AC circuit breaker between the inverter and the grid.
• Method 2: Connect DI and PGND in COM2 port to trigger quick shutdown. Disconnect DI
and PGND to exit the quick shutdown mode.
• The quick shutdown is not supported if optimizers are configured for some PV
modules.
• Please check regularly whether the quick shutdown function is normal.
