Data in the Consumption diagram:
• Current value of consumption: Power that your household
is currently drawing from your system (direct consumption or
internal power supply for 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 system
For systems with battery, the power comes preferably directly
from the system (direct consumption). If the power produced by
the system is not sufficient, the remaining power is supplied by
discharging the battery.
• Battery discharging (only displayed for systems with
battery): Power that your household is currently drawing from
the battery
• Direct consumption (only displayed for systems with
battery): Power that your household is currently drawing from
your system, without intermediate storage in the battery
Data in the Generation diagram:
• Current Power: Power that your system is currently
generating
• Self-consumption: Power that your household is currently
drawing directly from your system (direct consumption) and
the power that your PV system is currently storing in the battery
(battery charging)
In systems without batteries, self-consumption is the same as
internal power supply.
• Battery charging (only displayed for systems with battery):
Power that your system is currently storing in the battery
• Grid feed-in: Power that your system is currently feeding in to
the utility grid
If your 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.
