SMA SUNNY ISLAND 4.4M Operating Manual page 15

SMA Solar Technology AG
To prevent personal injury or property damage and to ensure long-term operation of the batteries, read this section
carefully and observe all safety information at all times.
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 battery management is intrinsically safe and will protect the battery.
• Ensure that the lithium-ion batteries are approved for use with the Sunny Island (see technical information "List of
Approved Batteries" at www.SMA-Solar.com).
• If no lithium-ion batteries approved for the inverter can be used, lead-acid batteries can be used.
• Verify that the battery complies with locally applicable standards and directives and is intrinsically safe.
Danger to life due to explosive gases
Explosive gases may escape from the battery and cause an explosion.
• Protect the battery environment from open flames, embers and sparks.
• Install, operate and maintain the battery in accordance with the manufacturer's specifications.
• Do not burn the battery and do not heat it beyond the permitted temperature.
• Additional measures for lead-acid batteries: Ensure that the battery room is sufficiently ventilated.
Chemical burns due to battery electrolyte
If handled inappropriately, battery electrolyte can leak from the battery and cause irritation to the eyes, respiratory
system and skin.
• Install, operate, maintain and dispose of the battery according to the manufacturer's specifications.
• Whenever working on the battery, wear suitable personal protective equipment such as rubber gloves, an
apron, rubber boots and goggles.
• Rinse acid splashes thoroughly for a long time with clear water, and consult a doctor immediately.
• If acid fumes have been inhaled, consult a doctor immediately.
Risk of burns due to flashes
Short-circuit currents in the battery can cause heat build-up and flashes.
• Remove watches, rings and other metal objects prior to carrying out any work on the battery.
• Use insulated tools for all work on the battery.
• Do not place tools or metal parts on the battery.
