Rapid Shutdown Initiation

Upon initiating Rapid Shutdown, the MCI excitation signal is lost and all MCIs will open within 30 seconds, bringing all voltages across the solar assembly and PV strings to safe levels.

Rapid Shutdown Manual Initiation

Rapid Shutdown can be manually initiated using the Solar Inverter AC breaker, AC disconnect, or the System Shutdown Switch if one is present. The loss of AC grid is detected and RSD is initiated.
