Battery Safety Information

This section contains safety information that must be observed at all times when working on or with batteries.

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.

WARNING

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.

  1. 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).
  2. If no lithium-ion batteries approved for the inverter can be used, lead-acid batteries can be used.
  3. Verify that the battery complies with locally applicable standards and directives and is intrinsically safe.

WARNING

Danger to life due to explosive gases

Explosive gases may escape from the battery and cause an explosion.

  1. Protect the battery environment from open flames, embers and sparks.
  2. Install, operate and maintain the battery in accordance with the manufacturer’s specifications.
  3. Do not burn the battery and do not heat it beyond the permitted temperature.
  4. Additional measures for lead-acid batteries: Ensure that the battery room is sufficiently ventilated.

WARNING

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.

  1. Install, operate, maintain and dispose of the battery according to the manufacturer’s specifications.
  2. Whenever working on the battery, wear suitable personal protective equipment such as rubber gloves, an apron, rubber boots and goggles.
  3. Rinse acid splashes thoroughly for a long time with clear water, and consult a doctor immediately.
  4. If acid fumes have been inhaled, consult a doctor immediately.

WARNING

Danger to life due to burns caused by electric arcs through short-circuit currents

Short-circuit currents in the battery can cause heat build-up and electric arcs. Heat build-up and electric arcs may result in lethal injuries due to burns.

  1. Remove watches, rings and other metal objects prior to carrying out any work on the battery.
  2. Use insulated tools for all work on the battery.
  3. Do not place tools or metal parts on the battery.
  4. Observe all safety information of the battery manufacturer.

CAUTION

Risk of burns due to hot battery components

Improper battery connection may result in excessively high transition resistances. Excessive transition resistances give rise to localized heat build-up.

  1. Ensure that all pole connectors are connected with the connecting torque specified by the battery manufacturer.
  2. Ensure that all DC cables are connected with the connecting torque specified by the battery manufacturer.

NOTICE

Damage to the battery due to incorrect settings

The set battery parameters influence the charging behavior of the inverter. The battery can be damaged by incorrect settings of the battery type, nominal voltage and capacity parameters.

  1. Set the correct battery type as well as the correct values for nominal voltage and battery capacity when configuring.
  2. Ensure that the values recommended by the manufacturer are set for the battery (refer to the technical data of the battery in the manufacturer documentation).
