Info

AC power sources can be, for example, KOSTAL solar inverters, other inverters, combined heat and power (CHP) units, small wind turbines or other energy sources in your own house grid.

 

1

Grid energy:

- For use by local consumers
- For charging the battery from the public grid, e.g. to protect the battery in winter or via external battery control/battery manager.

2

Battery energy:

- For use by local consumers
- For feeding into the public grid (only possible via external battery manager)

The energy management system (EMS) controls the distribution of energy between the DC side (battery) and the AC side (house grid, public grid). For this purpose, the EMS checks for consumption in the internal house grid. The logic of the EMS then calculates and controls the optimal usage of energy. The self-consumers are given priority for using the PV energy generated.
