frame shown in the power graph.

Description
Generation has increased to approx. 3300 watts. This is used to cover consumption (blue)
and charge the storage system (green) at a minimal level. Charging with higher power is
prevented by the intelligent charging management system. This function ensures that
storage capacity is kept free in order to store part of the midday peak in the storage sys-
tem later.
Consumption (blue) exceeds generation and must be supplemented by the storage sys-
tem.
A breach of the feed-in limit is no longer expected. PV generation covers consumption
(blue) and the surplus is stored in the battery (green) so that it will be fully charged by
evening.
From this point PV generation is no longer sufficient to cover consumption. The differ-
ence is discharged from the storage system.
The storage system discharge (red) covers total consumption.
The storage system is discharged and consumption is covered by usage from the public
grid.
The pie chart symbolises the electrical power
gained by the generator in the analysed time frame.
The feed-in power is marked white in the chart. The
yellow part represents self consumption. Self con-
sumption is the part of the generated power that
has not been fed in, bus has instead been stored
temporarily in the battery or has been consumed.
