WARNING
Danger to life due to fire or explosion
In rare cases, an explosive gas mixture can be generated inside the product under fault conditions. In this state,
switching operations can cause a fire or explosion. Death or lethal injuries due to fire or flying debris can result.
• In case of error, only carry out corrective measures specified by SMA Solar Technology AG (for corrective
measures see section "troubleshooting" in the detailed manual. If no corrective measures are specified, do not
perform any actions on the product. Contact the Service.
• Ensure that unauthorized persons have no access to the product.
• Disconnect the AC circuit breaker and secure it against reconnection.
• Disconnect the battery from the product via an external disconnection device.
WARNING
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-12: Check whether a circuit breaker has a higher trip characteristic than B6 (B6A).
• SI6.0H-12 and SI8.0H-12: 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.
WARNING
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.
CAUTION
Risk of burns due to short-circuit currents on the disconnected inverter
The capacitors in the DC input area of the inverter store energy. After the battery is isolated from the inverter,
battery voltage is still temporarily present at the DC terminal. A short circuit at the DC terminal of the inverter can
lead to burns and may damage the inverter.
• Wait 15 minutes before performing any work at the DC terminal or on the DC cables. This allows the
capacitors to discharge.
CAUTION
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• Mount the inverter in such a way that it cannot be touched inadvertently during operation.
