Maximum permitted energy costs:
Maximum permissible energy costs You can set the maximum permissible energy costs for
operation of the load. The price range of the slider is based on the highest and the lowest possible
energy costs, e.g. the highest energy costs for operation exclusively with expensive grid current and
the lowest energy costs for operation exclusively with PV energy, the cost of which is calculated
based on the feed-in tariff less the self-consumption tariff. In addition, if Limiting of the active
power feed-in is activated, surplus PV energy can be taken into account which is free, as it would
otherwise be derated.
Example: Operating the load exclusively with free energy
A pond pump should only be switched on if there is more PV energy available than is permitted to
be fed into the utility grid.
• The slider is set to 0 Euro/kWh. When enough surplus PV energy is available, the pond
pump will be switched on.
Adding an Additional Time Period
If a load is not to run throughout the day, but rather at predefined intervals (e.g. pond pump), you
must add several consecutive time periods for this day. Here, the number of time periods equates to
the number of intervals in which the load is to run.
