Energy-saving mode

The battery inverter has an energy-saving mode where the power consumption is less than 7 watts. When entering and leaving the energy-saving mode, the battery inverter behaves depending on the operating mode (stand-alone mode and parallel grid operation mode).

Energy-saving mode during stand-alone mode

In stand-alone mode, the energy-saving mode is coupled to the 3-level battery protection mode ( > Changing the Battery Protection Mode in Off-Grid Systems). The power saving mode occurs under the following conditions:

• The SOC limiting value of level 1 in battery protection mode has been undershot and charging current has flowed into the battery within 5 minutes.

• The SOC limiting value of level 2 in battery protection mode has been undershot and no charging current has flowed into the battery within 5 minutes.

Energy-saving mode during parallel grid operation mode

In parallel grid operation mode, the energy-saving mode is coupled to the battery utilization ranges for self-consumption systems. The power saving mode occurs under the following conditions:

• In the case of self-consumption systems without a battery-backup grid, this occurs when there is no surplus PV energy available to charge the battery in the state-of-charge conservation range PVRes ( > Changing the Battery Usage Regarding Systems for Increased Self-Consumption Without a Battery Backup Grid).

• For self-consumption systems with battery-backup grid, the energy-saving mode activates when no surplus PV energy is available to charge the battery in the state-of-charge conservation range PVRes or when the deep discharge protection range BatRes is reached ( > Changing the Battery Usage Regarding Battery-Backup Systems with Increased Self-Consumption).
