Configure tariffs
In smart-me billing, you can either work with electricity tariffs or with virtual tariffs.
Systems with solar tariffs (ZEV, vZEV)
Virtual tariffs and vZEV tariffs
Virtual tariffs allow you to define your own dynamic tariff model for energy billing. This can be used to distinguish between tenants drawing electricity from a solar installation or from the grid for their own consumption if merging of private energy consumption (tenant electricity) is used.
Please note that all normal electricity tariffs must be deleted.
You will see all the virtual tariffs that have already been entered under Virtual tariffs. Click on Add.

Tariff type
Solar tariff vZEV:
This allows a global solar tariff to be created in a ZEV or a vZEV. The solar energy is distributed evenly to all consumers and is based on the sum of the house balances (ZEV) and the sum of the productions (solar meter). With this tariff, it is not necessary to measure 100% of the loads if a house connection meter is physically present. The need for virtual summation meters is eliminated with this tariff.Solar tariff (legacy):
This allows the energy from a solar system to be offset within a ZEV. This means that ZEVs can be implemented with or without a balance meter (VNB). The tariff requires a virtual total meter for all relevant loads (100% measurement).Battery tariff (legacy):
This allows the energy of an AC-coupled battery to be distributed within a ZEV. This tariff is only compatible with the solar tariff (legacy). The tariff requires a virtual total meter for all relevant loads (100% measurement).Grid tariff (normal tariff):
This is used to charge for grid electricity. If required, this can also be divided into high and low tariff periods.
Generals about tariffs
A price / consumption unit and validity can be stored for each tariff.
Price/kWh: The price for this tariff
Valid from: The start date from which this tariff applies
Valid until: The end date for the validity of this tariff
Additional condition
You can define when this tariff is valid with an additional condition. This can be a time period (e.g. for high/low tariff) or any other condition. The condition must have been defined beforehand as an If/ Then action.
Additional notes:
When you have defined all tariffs, it is mandatory to click on "Recalculate". This calculates and activates all virtual tariffs. This process can take a few hours.
If one or more conditions are stored, all tariffs must cover the 24 hours of the day. If a normal tariff without conditions is stored, it automatically catches all energy quantities that cannot be allocated and thus covers the 24 hours. Alternatively, care must be taken that the times of the conditions are configured correctly (see example above).
Configure solar tarif vZEV
The vZEV solar tariff enables the implementation of ZEV and vZEV solutions.
The vZEV solar tariff configuration calculates the effective surplus of a virtual ZEV and the effective grid consumption based on several solar production meters and house connection meters.
The calculation takes into account the individual surpluses of a house and at the same time the demand of other houses for this surplus.
If there is a demand, it is made available to the neighboring house. If there is none, the surplus is identified as grid feed-in.
The solution supports the following implementations:
Realization of a normal ZEV with or without balance meter
vZEV: Several smart-me ZEVs with house connection meters
vZEV: Combination of smart-me ZEVs with buildings with consumers only
vZEV: Combination of smart-me ZEVs with EFHs with solar systems
vZEV: Several smart-me ZEVs in combination with former VNB practice models
Note: The battery cannot be tariffed separately with this tariff system.

Configure solar- and battery tariffs with legacy tariffs
The solar tariffs and battery tariffs of the Legacy series enable the implementation of a ZEV with or without a balance meter.
The use of this tariff group enables the following:
ZEV with or without a balance meter
Different tariffs for battery and solar power
Prerequisite for use:
Application of a 100% metering concept, all metered consumers must correspond to 100% of the load.
Requires a virtual total meter for all loads.
Solar or battery meter
For the solar and battery tariff, you must specify the meter that measures the battery or the solar system.
Total consumption
For solar and battery tariffs, you must specify a meter that measures all consumers to which this energy is to be distributed. This is usually a virtual meter that adds up all consumers (note that virtual meters require an additional license).
Balance meter
For solar tariffs and battery tariffs, a balance meter can optionally be specified. If the balance meter is listed, the energy that is fed into the grid is taken into account when calculating the solar tariff. This means that only the solar energy that was actually consumed in the building is distributed per 15 minutes (energy available = PV production - grid feed-in).
Please note: If the physical balance meter is dispensed with, deviations of 10-15% in the allocation of tariffs are not unusual.
Virtual meter
The virtual meter (total consumption) is required to create the reference for tariff allocation. This is formed from all load meters and is subject to a cost plan
(1x professional license)
The summed up meters must be exact 100% of the load. If you have meters in series the meter more near to te house connection is relevant only.
Solar meters, battery meters and house connection meters are to be excluded.If several solar systems are in the system and cannot be measured together, an additional license is required for total production

Peak electricity tariffs
Peak electricity tariffs can be used to cover extended or new types of electricity models from energy suppliers.
Dual tariff for basic consumption + peak power tariff
(virtual tariffs in combination with the peak tariff)Single tariff for basic consumption + peak power tariff
(virtual tariffs in combination with the peak tariff)Peak tariff only without basic tariffs
Validity period:
The validity period of a peak tariff is limited to 1 year, it can be created several times for several years.
Peak tariffs are either based on the monthly costs incurred (energy supplier bill) or are dependent on the stored tariff and the active measurement of the main measuring point.
Beispiel eines erfassten Stromtarifes mit Kostenbasis (Kosteneintragung)
General mode of operation:
The allocated peak tariff costs or the automatically calculated costs based on metering and the stored tariff are allocated to the consumers in the selected calculation interval when the invoice is created.
The basis for this is the respective electricity peak caused by each individual consumer in the billing period and the selected calculation interval.
Peak tariffs without active main metering (cost entry)
Suitable for all systems that do not have a physical balance measurement at the grid connection.
Peak tariffs with active main metering (automatic cost calculation)
Suitable for all systems that do have a physical balancing meter of the grid connection..
Systems with only grid tariffs
Electricity tariffs (only valid if VEWA function not used)
To access the electricity tariff settings, click on the property on the left and scroll to the green Tariffs Electricity window. Here the two tariffs T1 and T2 are displayed. Select one of the tariffs and click on Edit to make changes to its properties (e.g. name, price, etc.).
In order to be able to work with the electricity tariffs, the tariff signal of the electricity company must be connected to the tariff input of the corresponding meters.
