11 Cleaning and Maintenance
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 or serious chemical burns.
• Protect the battery enclosure against destruction.
• Do not open or deform the battery.
• Do not throw batteries into fire. Batteries may explode in fire.
• 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.
• Install, operate, maintain and dispose of the battery according to the manufacturer's specifications.
Damage to the battery due to incorrect settings
The set battery parameters influence the charging behavior of the Sunny Island inverter. The battery can be
damaged by incorrect settings of the battery type, nominal voltage and capacity parameters.
• 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). Note that the battery charging behavior names used by
SMA Solar Technology AG and the battery manufacturer may, in some cases, differ in meaning (for the battery
charging behavior of the Sunny Island inverter, see technical information "List of Approved Lithium-Ion Batteries"
).
• Set the battery capacity for a ten-hour electric discharge (C10). The battery manufacturer specifies the battery
capacity in relation to discharge time.
Procedure:
1. Stop the system and switch off the Sunny Island (see Section 4, page 20).
2. Ensure that the battery is not grounded unintentionally.
If the battery is unintentionally grounded, identify the connection between the battery and ground potential and
remove the unintentional connection. This helps to prevent electric shock caused by malfunction of other system
devices.
3. Open the load-break switch of the BatFuse and secure against reconnection.
4. Remove the battery to be replaced (see battery manufacturer's manuals).
5. Mount and connect the new battery (see manuals of the battery manufacturer). The battery must comply with the
technical requirements of the Sunny Island inverter (refer to the Sunny Island inverter installation manual for
technical data of the DC connection).
6. Quickly close the load-break switch of the BatFuse and close the BatFuse (see BatFuse installation manual).
7. Switch the Sunny Island on (see Section 4.1, page 20).
8. If the Sunny Remote Control displays <Init System>
displays the QCG.
9. Select the menu New Battery and press the button.
10. Confirm with Y.
