Smart battery control

Applies to PLENTICORE plus G2 from software version 02.20.

The inverter has an intelligent generation and consumption forecast (intelligent battery control) which, in conjunction with a connected energy storage system, optimally supplies the generated electricity to consumers in your own household.

By using this feature, the majority of the energy produced can be used by the consumer themselves, thus helping to reduce electricity procurement costs.

The intelligent battery control recognises and takes into account the times of day when the most energy is needed in the household. The system then independently derives forecasts of how household consumption will develop in the future and regulates the charging or discharging of the battery accordingly.

This ensures that as much of the energy produced as possible is consumed by the household itself and that as little energy as possible is fed unused into the public grid.

This function should not be used if an electric vehicle is also being charged via the domestic grid. In this case, it is not possible to determine a clear consumption forecast.

With the help of the intelligent generation and consumption forecast, the use of the generated energy is optimised beyond simple electricity storage, while at the same time complying with all legally prescribed power limitations (e.g. 60% EEG regulation).

Intelligent battery control should only be activated if curtailment has been activated in the inverter. This means that the connected PV power at the inverter must be greater than the power that the inverter feeds into the grid.

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

Example of control without intelligent battery control

1

Home consumption (own requirement)

2

Battery charge

3

Feed-in to the public grid

4

Power limitation of feed-in to e.g. 50%

5

Unused PV energy

The figure Control without intelligent battery control shows that without intelligent battery control, the PV energy generated remains unused, especially when there is high solar radiation, e.g. due to a power limitation of 50%.

With intelligent battery control and generation and consumption forecasting, the battery is only charged when the surplus energy cannot be consumed in the home network or fed into the public grid. This means that the PV energy generated is used sensibly or stored in the battery.

As a result, consumers increase their self-consumption and degree of self-sufficiency.
