3. Switch-on of consumers (via sonnenSmart plug)
The consumers are activated as soon as the feed-in limit is exceeded. The consumers are
deactivated again once the level has dropped below the limit and stayed there for at least
three minutes.
4. Reduction of PV power
Production is reduced via an integrated switch contact on the inverter. This limited the PV
inverter to a set power output. In order for this to occur, the inverter must support power
reduction using a switch contact or an external solution (e.g. a solar datalogger). Configur-
ation and connection are carried out by the electrician.
3.4.3 Intelligent charging management
The charging behaviour of the storage system is controlled via intelligent charging man-
agement. The aims of this intelligent control are as follows:
• Storage of the midday peak in the storage system (sufficient storage capacity must still
be available for this)
• Full charging of the storage system until evening (so there is sufficient energy for night-
time)
The intelligent charging management only takes effect in storage systems which are oper-
ated together with PV systems for which a feed-in limit is activated.
Functional principle of intelligent charging management
The storage system is connected to a server via the internet. This server creates a con-
sumption and production forecast for the individual hours of the day in question. The pro-
duction forecast is based on
• the weather forecast,
• the nominal power of PV system and
• the orientation of the PV system.
The consumption forecast is calculated based on actual consumption from the previous
week.

consumption forecast (blue)
The figure on the left shows an example of a pro-
duction and consumption forecast. In this example,
an average consumption of 0.5 kW and a produc-
tion of approx. 9 kW are calculated for the time
between 10 and 11 a.m.
