General Power Control

In the interests of the highest possible internal power supply and the highest possible self-consumption, the power control at the grid-connection point has the following objectives:

• Before the PV system feeds into the utility grid, this electrical energy should be consumed directly or stored intermediately in a battery.

• Before the loads draw energy from the utility grid, this energy should be provided by the PV system or by discharging the battery.

The energy management system achieves these objectives taking the forecast for PV generation and electricity consumption for the current day into account.
