Tripping the Emergency Disconnection of the System
Effects of an emergency disconnection
Emergency disconnection triggers the uncontrolled shutdown of the system and unsaved data is lost.
• Only trip the emergency disconnection to avoid danger or consequential damage.
• In the event of an emergency disconnection in a multicluster system, always check whether any fuse elements
in the Multicluster-Box, such as circuit breakers, have tripped. If any fuse elements have tripped, reactivate
these fuse elements.
Procedure:
1. For systems with one Sunny Island, press the "Off" button on the
Sunny Island.
2. For systems with up to three Sunny Island inverters, press the "Off" button on the master.
3. For multicluster systems, press and hold the "Off" button on the master of the main cluster.
☑ The inverter LED is off on all Sunny Island inverters.
