Pay particular attention to the number of licenses required, this example supports ZEV or vZEV with a uniform price for solar and battery power.

• n+1 Virtual PV totalizer (for visualizations)

If you want to differentiate the tariffs for solar and battery power (only possible if the battery is AC-coupled and metered separately), it is necessary to provide additional licenses for the virtual total consumption

• n+2 PV total meters + virtual total consumption meter
  (battery tariffs)

Additional explanation:

• Licenses for meters connected to the M-Bus gateway (heat, water, gas)

• Load management for each charging station + the reference point (n + 1)

• 2 car charging stations per apartment in the garage + dynamic load management
  (Billing Smart-me Billing) (+8 cloud service licenses)

• 4 external car charging stations, public charging points with eCarUp + dynamic load management
  (Billing with credit card) (+4 cloud service licenses)
