8.2 Battery Management
8.2.1 Safety When Setting the Battery Management Parameters
This section contains safety information to be observed when configuring the battery management. To prevent property
damage and to ensure the long-term operation of the product, read this section carefully and observe all safety
information.
8.2.2 Adjusting the Battery Management to the Battery
For further information relating to the battery management and the charging behavior of the Sunny Island inverter,
see the Technical Information "Battery Management" on the supplied CD.
Procedure:
1. Switch to expert mode on the Sunny Remote Control (see the Sunny Island inverter operating manual).
2. Select the parameter 222.01 BatChrgCurMax and set it to the maximum battery charging current recommended
by the battery manufacturer.
3. Set the parameters for boost charge.
• Select the parameter 222.02 AptTmBoost and set to the boost-charge absorption time recommended by the
battery manufacturer.
• Select the parameter 222.07 ChrgVtgBoost and set it to the cell-voltage setpoint recommended by the battery
manufacturer for boost charge.
4. Set the parameters for full charge.
• Select the parameter 222.03 AptTmFul and set to the full-charge absorption time recommended by the battery
manufacturer.
• Select the parameter 222.05 CycTmFul and set to the full-charge cycle time recommended by the battery
manufacturer.
• Select the parameter 222.08 ChrgVtgFul and set it to the cell-voltage setpoint recommended by the battery
manufacturer for full charge.

Damage to the battery due to incorrect settings
Incorrect settings lead to premature aging of the battery. The parameter settings in the menu 220# Battery,
222# Chargemode, 262# BatUsage, and 223# Protection impact the charging behavior of the Sunny Island
inverter.
• Check whether initial battery charging with special settings is required.
If an initial charge is required, adjust the charging behavior of the Sunny Island inverter for one-off initial charging
(see Section 8.2.2, page 67).
• Ensure that the values for the battery as recommended by the battery manufacturer are set in the menus
222# Chargemode (see Section 8.2.2, page 67), 262# BatUsage (see Section 8.2.3, page 68 and Section
8.2.4, page 69), and 223# Protection (see Section 8.2.5, page 75) (for the technical data of the battery see
the documentation provided by the battery manufacturer). Note that the charging behavior names used by
SMA Solar Technology AG and the battery manufacturer may, in some cases, differ in meaning (for the charging
behavior of the Sunny Island inverter, see the Technical Information "Battery Management"). Tip: For questions
relating to the settings of the Sunny Island inverter, please contact the SMA Service Line.
