It is important to understand how the data from the smart-MAIC
energy monitor is saved at different time intervals. It is especially
important to understand the calculation principle for the Power
[W] parameter when it is converted from electrical power into
electrical energy.
As mentioned, there is an arrow on every current transformer. If
the arrow is positioned towards the consumer, the monitoring data
will be saved as follows:
- active power (consumption) in the [W] Power parameter;
- reversible active power (generation) in the [rW] Revers Power
parameter;
- accumulative meter of consumed energy in [Wh] Energy;
- accumulative counter of reversible energy in [rWh] Energy.
