3 Safety
Risk of crushing injuries due to movable generator parts
Moving parts in the generator can crush or sever body parts. A generator can be started
automatically by the Sunny Island.
• Only operate the generator with the safety equipment.
• Install, maintain, and operate the generator according to the manufacturer's specifications.
Danger to life due to incompatible lithium-ion battery
An incompatible lithium-ion battery can lead to a fire or an explosion. Use of incompatible
lithium-ion batteries can also make the user's battery management system unsafe, and void
manufacturers' warranties. To avoid fire or explosion, we strongly recommend doing the following:
• Verify that the battery complies with locally applicable standards and directives, and is
intrinsically safe.
• Verify that the particular lithium-ion battery type is approved for use with the
SMA Sunny Island inverter (please see "List of Approved Lithium-Ion Batteries" under the
Technical Information tab at www.SMA-America.com).
• If manufacturer approved Sunny Island lithium-ion batteries are not available, you may use
lead acid batteries.
Destruction of the Sunny Island due to parallel connection of Sunny Island inverters
which are set to different grid voltages
• Do not connect a Sunny Island in parallel if its line voltage is set to different values.
Batteries may be destroyed due to deep discharge
The self-consumption of the Sunny Island discharges the battery. In standby mode, this load is about
4 W and about 25 W in no-load operation.
• If you install the Sunny Island and do not wish to use it immediately, switch the Sunny Island
off (see Section 9.3 "Switching Off", page 76).
• If you want to decommission the Sunny Island for a long period, switch the Sunny Island off
(see Section 9.3 "Switching Off", page 76).
Connection requirements
Be sure to observe all valid regional standards and directives.
