Danger to life due to incompatible lithium-ion battery
An incompatible lithium-ion battery can lead to a fire or an explosion. With incompatible lithium-ion batteries, it is not
ensured that the battery management is intrinsically safe and will protect the battery.
• Ensure that the battery complies with the locally applicable standards and directives and is intrinsically safe.
• Ensure that the lithium-ion batteries are approved for use with the Sunny Island.
The list of lithium-ion batteries approved for the Sunny Island is updated constantly (see Technical Information "List
of Approved Lithium-Ion Batteries" at www.SMA-Solar.com).
• If no lithium-ion batteries approved for Sunny Island inverters can be used, you should use lead-acid batteries.
Danger to life due to explosive gases
Explosive gases may escape from the battery and cause an explosion. This can result in fatal or serious injury.
• Protect the battery environment from open flames, embers, or sparks.
• Install, operate, and maintain the battery in accordance with the manufacturer's specifications.
• Do not heat the battery above the temperature permitted or burn the battery.
• Ensure that the battery room is sufficiently ventilated.
Chemical burns and poisoning due to battery electrolyte
If handled inappropriately, battery electrolyte can cause irritation to the eyes, respiratory system, and skin, and it can
be toxic. This may result in blindness and serious chemical burns.
• Protect the battery enclosure against destruction.
• Do not open or deform the battery.
• Whenever working on the battery, wear suitable personal protective equipment such as rubber gloves, apron,
rubber boots, and goggles.
• Rinse acid splashes thoroughly with clear water and consult a doctor.
• Install, operate, maintain, and dispose of the battery according to the manufacturer's specifications.
Risk of injury due to short-circuit currents
Short-circuit currents in the battery can cause heat build-up and electric arcs. Burns or eye injuries due to flashes may
result.
• Remove watches, rings, and other metal objects.
• Use insulated tools.
• Do not place tools or metal parts on the battery.

Risk of burns due to short-circuit currents on the disconnected Sunny Island
The capacitors at the DC connection input area store energy. After the battery is isolated from the Sunny Island, battery
voltage is still temporarily present at the DC connection. A short circuit at the DC connection can lead to burns and may
damage the Sunny Island inverter.
• Wait 15 minutes before performing any work at the DC connection or on the DC cables. This allows the capacitors
to discharge.
