The multi-tariff feature allows you to set up different tariffs for storing energy values.

The energy values for different tariffs are stored in registers that correspond to each of those tariffs.

Multi-tariff example

The multi-tariff feature can be used when a utility has set up tariff schedules with different rates based on what day or time of day energy is consumed.

  Tariff energy containers

In the above illustration, the area under the power curve equals the energy consumed.

Typically, the utility sets tariff schedules so the cost of energy is higher during high demand or high energy consumption times. How these “tariff energy containers” are configured determines how fast these containers fill, which correlates to increasing energy costs. The price per kWh is lowest at tariff T1 and highest at tariff T2.
