Battery Management

A

The inverter uses the battery within this range for increased self-consumption. When more energy is needed than can be supplied by the PV modules, the battery is discharged.

B

The value indicates the percentage of battery charge to be retained for secure power supply operation and battery-backup operation. This battery charge cannot be used in parallel grid operation, even if the secure power supply operation and battery-backup operation are deactivated.

C

In this range, the battery is no longer discharged, even in secure power supply operation or battery-backup operation.

D

The value specifies which percentage of the Real SOC is to be reserved as deep discharge protection. This value corresponds to a User SOC of 0%. When the state of charge is displayed as 0% (User SOC), the battery is actually (Real SOC) still charged to as much percentage as this value indicates.
