Chapter 10—Multi-tariff feature

This section describes how to set up different tariffs for storing energy values in registers that correspond to each of those tariffs. An example of when this feature can be used is when a utility has set up tariff schedules with different rates based on what day or time of day energy is consumed.

The meter supports configuration of up to 4 different tariffs.

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.

Multi-tariff feature overview

The meter supports multiple tariffs to measure and monitor energy usage that can be used in billing or cost applications. There are different tariff modes you can use to determine what tariff is applied and when: Command mode, Time of Day mode, and Input mode.
