Battery Management
State of charge ranges of the battery
Range | Inverter parameters | Inverter behavior |
|---|---|---|
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 | Battery > Areas of application > Minimum width of backup power area (BatUsDm.BckDmMin) | The value indicates the percentage of battery charge to be retained for battery-backup operation. This battery charge cannot be used in parallel grid operation, even if the battery-backup operation is deactivated. |
C | Device > Self-consumption > Lower battery discharge limit (BatChaSttMin) | In this range, the battery is no longer discharged, even in battery-backup operation. |
D | Battery > Areas of application > Minimum width of deep discharge protection area (BatUsDm.DschProDmMin) | 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. |
