Difference between internal power supply and self-consumption in PV systems with
batteries:
Internal power supply = the sum of power/energy that your household draws directly from your PV
system (direct consumption) and the battery (battery discharging). The internal power supply
therefore indicates from which source your household is supplied with PV energy - from the PV system
or from the battery.
Self-consumption = the sum of the power/energy that your household draws directly from your PV
system (direct consumption) and the power/energy that your PV system stores in the battery (battery
charging). The self-consumption therefore indicates how the PV energy is consumed - via your
household or via battery charging.
In PV systems without batteries, self-consumption is the same as internal power supply.
