When enabled, the self-consumption strategy will use the selected sub-meter as the reference point instead of the main grid meter. This is useful when self-consumption should be measured at a specific sub-meter in the installation rather than at the grid connection point. Note: the selected meter must be a power meter that is part of the installation. By default this feature is disabled.
Sometimes there are contractual agreements that a part of an installations should not be included in the self-consumption optimization. Imagine the scenario below: This can be a company that has a special contract for his 'sub site' with only solar production, and gets a fixed (high) injection fee for the energy produced by his solar production produced by this sub installation.consumption
Therefore, we'd like to exclude this part of the installation from the self-consumption control, but still guard or import and export limits on grid connection point.
This can be enabled -if and only if- both a grid meter and a secondary 'self-consumption meter' is installed. Then, follow the steps below:
When the self-consumption meter is removed, re-added, this feature is automatically disabled.
