Battery settings

Battery type

Select the battery connected to the inverter.

Battery control
(only possible with service code)

The battery can be controlled via an external battery management system (e.g. energy supplier). In this case, the charging and discharging power of the battery is controlled by the external provider. The system operator then receives remuneration from the external provider for the energy supplied, for example. External battery control

Internal (default):

External control is deactivated.

Externally via digital I/O:

External battery management is carried out via the digital inputs on the Smart Communication Board (terminal X401) of the inverter. A default setting can be selected, or the digital inputs can be configured according to the provider's specifications.
If the control signals are not received, the system switches to internal control. The device status can still be read out in parallel via Modbus (TCP) / SunSpec. External battery control

Externally via Modbus (TCP):

External battery management is carried out via the Modbus RTU protocol. The control signals are received via the LAN interface. If the control signals are not received for the set duration, the system switches to internal control. It is still possible to read the device status via Modbus (TCP) / SunSpec in parallel.

Additionally, set the time for external battery control timeout. If the signals via Modbus are interrupted or fail to arrive, the system will switch to internal control after the time has elapsed.

Battery charging as of grid surplus of [W]

Enter a minimum grid surplus value as of which the battery is charged. (Default 50 W.)

Example: If a value of 50 W is set, the battery is charged when feed-in into the public grid (grid surplus) is more than 50 W. Charging to the battery is blocked if the value is below 50 W.

Min. state of charge (SoC) [%]

Set the minimum depth of discharge of the battery.

Intelligent battery control

Not supported by all battery types.

This function controls the charging and discharging of the battery completely automatically. This function should only be activated if the connected PV power is greater than the PV power of the inverter (inverter curtailment to 70%, for example). You should not use this function if an electric vehicle is being charged via a wallbox, as it is not possible to determine a clear consumption forecast in this case.

If the storage of surplus AC energy from local generation (Smart AC Link function) has been activated, the "Intelligent Battery Control" function is not available.

A detailed description can be found at Smart battery control

Storage of excess AC energy from local generation

If there is an additional AC energy source in the local house grid (e.g. an additional PV system or a combined heat and power unit), the AC energy generated can be stored in a battery connected to the PLENTICORE.

NOTE! The function can only be activated if the energy meter has been installed at the grid connection point (position 2).

Activated: The AC energy generated can be stored in the battery.

Deactivated: Extra generated AC energy is not stored in the battery.
