2 Safety
Danger to life due to fire or explosion
In rare cases, an explosive gas mixture can be generated inside the inverter under fault conditions. In this state,
switching operations can cause a fire inside the inverter or explosion. Death or lethal injuries due to hot or flying
debris can result.
• In the event of a fault, do not perform any direct actions on the inverter.
• Ensure that unauthorized persons have no access to the inverter.
• Disconnect the battery from the product via an external disconnection device.
• Disconnect the AC circuit breaker, or keep it disconnected in case it has already tripped, and secure it against
reconnection.
• Only perform work on the inverter (e.g., troubleshooting, repair work) when wearing personal protective
equipment for handling of hazardous substances (e.g., safety gloves, eye and face protection, respiratory
protection).
Risk of injury due to toxic substances, gases and dusts.
In rare cases, damages to electronic components can result in the formation of toxic substances, gases or dusts
inside the inverter. Touching toxic substances and inhaling toxic gases and dusts can cause skin irritation, burns or
poisoning, trouble breathing and nausea.
• Only perform work on the inverter (e.g., troubleshooting, repair work) when wearing personal protective
equipment for handling of hazardous substances (e.g., safety gloves, eye and face protection, respiratory
protection).
• Ensure that unauthorized persons have no access to the inverter.
Danger to life from electric shock due to circuit breakers that cannot be tripped
In off-grid systems and battery-backup systems, the Sunny Island can only trip circuit breakers up to a certain
tripping characteristic. Circuit breakers with a higher operating current cannot be tripped. Under fault conditions, a
voltage that poses a danger to life may be present on accessible parts for several seconds. Touching live
components can result in death or serious injury due to electric shock.
• SI4.4M-13: Check whether a circuit breaker has a higher trip characteristic than B6 (B6A).
• SI6.0H-13 and SI8.0H-13: Check whether a circuit breaker has a higher trip characteristic than B16 (B16A) or
C6 (C6A).
• If a circuit breaker has a higher trip characteristic than the specified circuit breakers that can be tripped, you
should also install a residual-current device of type A.
Risk of crushing injuries due to moving PV array parts
A generator can be started automatically by the Sunny Island. Moving parts in the PV array can crush or sever
body parts.
• Operate the generator only with the specified safety equipment.
• Carry out all work on the generator in accordance with the manufacturer's specifications.
