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.
