Rapid Shutdown Initiator

The DC load-break switch of the inverter is a system shutdown initiator, which also switches off the battery. It can be configured as a rapid shutdown initiator. If a rapid shutdown initiator is required in your system and the DC load-break switch of the inverter is not easily accessible, an external rapid shutdown initiator (e.g. SMA Rapid Shutdown Initiator RSI-US-50) must be installed in the system. Up to 3 inverters can be connected to this rapid shutdown initiator using an adapter matched to the Sunny Boy Smart Energy.
