When a Rapid Shutdown is triggered, the inverter reports it as an event and disconnects its AC side, so production stops. A separate success message confirms that the voltage at the DC inputs and the AC output has been discharged. Rapid shutdown is normally started by opening the main PV system AC disconnect, so check first whether that switch is in the Off (Open) position. A grid power failure can also start it: if the grid voltage does not come back within the ride-through time, the inverter disconnects and starts a rapid shutdown. If the shutdown event comes with an error in the Rapid Shutdown system instead, check whether the function is configured wrongly, whether the PV array disconnect switches work, and what their standby voltage is. Enable the function only when PV array disconnect switches are installed, because without them the inverter cannot discharge the DC conductors and may be damaged.

DC input voltage discharged
Event 9035 confirms that the voltage at the DC inputs and the AC output was discharged. The system must bring the DC conductors below 30 V within 30 seconds. This is a requirement, not a loss figure.
