The energy management system controls the distribution of energy between the DC side (PV generator) and the AC side (home network and public grid). To do this, the energy management system checks whether there is any consumption in the home network. The logic of the energy management system calculates and controls the optimal use of PV energy. The PV energy generated is primarily used for the consumer's own consumption. The remaining PV energy generated is fed into the public grid and remunerated.
The energy from PV generators is used for the following:
- local consumers
- Charging the battery
- Feed-in to the public grid in case of surplus
The energy from a connected battery is used for the following:
- Local consumers
- Feed-in to the public grid (only possible via external battery control/battery manager)
The energy from the public grid is used for the following:
- Local consumers
- Charging the battery, e.g. to protect the battery in winter or via external battery control/battery manager.
The energy from additional AC generators is used for the following:
- Local consumers
- Charging the battery
- Feed-in to the public grid in the event of surplus
INFO
AC generators may include, for example, KOSTAL inverters, other inverters, combined heat and power (CHP) units, small wind turbines or other energy sources within your home’s electrical network.
The storage of surplus AC energy from local generation (Smart AC Link) is enabled by default in the inverter and cannot be disabled. This prevents surplus power from being fed into the public grid unintentionally and ensures that self-consumption is maximised.
