Current Data in the diagram Consumption:
• Current value of consumption: Power that your household is currently
drawing from your PV system (direct consumption or internal power supply
for PV systems without battery), from the utility grid (purchased electricity)
and, if applicable, from the battery (battery discharging).
• Purchased electricity: Power that is currently being drawn by your
household from the utility grid.
• Internal power supply: Power that is currently being supplied to your
household by your PV system
For PV systems with battery, the power comes preferably directly from the
PV system (direct consumption). If the power produced by the PV system is
not sufficient, the remaining power is supplied by discharging the battery.
• Battery discharging* : Power that is currently being drawn by your
household from the battery.
• Direct consumption*: Power that your household is currently drawing
directly from your PV system, without intermediate storage in the battery.
Data in the diagram Generation:
• Current power: Power currently being generated by your PV system
• Self-consumption: Power that your household is currently drawing directly
from your PV system (direct consumption) and power that your PV system is
currently storing in the battery (battery charging).
In PV systems without batteries, self-consumption is the same as internal
power supply.
• Battery charging*: Power that your PV system is currently storing in the
battery.
• Grid feed-in: Power that your PV system is currently feeding into the utility
grid.
If your PV system is producing more power than your household needs at
the moment or can be stored in the battery, the surplus power is fed into the
utility grid.
