Battery Use by Systems for Increased Self-Consumption


4459087244

State of charge ranges of the battery in systems for increased self-consumption without battery backup

Range

Parameter

Battery inverter behavior

A

Self-consumption range (SlfCsmp)

The battery inverter uses the batteries within this range for increased self-consumption and for the "Time-of-Use" and "Peak Load Shaving" functions that can be configured in the power profile.

B

Range for maintaining battery state of charge (PVRes)

The battery inverter checks the current SOC every 24 hours. If the SOC is in range D, the batteries are recharged with 3 A from the utility grid until the upper limit of range B is reached. If the utility grid is not available, the batteries cannot be recharged.

D

Minimum width of deep-discharge protection range (BatRes)

The battery inverter recharges the connected batteries with 3 A. The recharging process does not stop until range A is reached.

If the utility grid is not available, the battery inverter cannot be switched on to check the SOC of the batteries.. The battery inverter and batteries are switched off. Exception: black start function

E

Lower limit of the deep-discharge protection range for disconnection (ProtRes)

When this range is reached and the utility grid is available, the battery inverter charges the batteries with 3 A from the utility grid until range A is reached.
