3 Service Description
The field of applications for the SunnyHomeManager ranges from its use as a simple energy meter to monitoring a
PV system and intelligent energy management.
SunnyHomeManager as energy meter
The SunnyHomeManager detects energy flows in both directions:
• Continuous recording of the energy generated by the PV system
• Measurement of the feed-in of generated energy into the utility grid as well as the consumption of energy from the
utility grid takes place at the point of interconnection.

Monitoring
Basic PV system status monitoring to confirm correct system performance:
All energy flows are recorded and evaluated. You will be notified about disturbances at an early stage.
Limitation of Active Power Feed-In
Local legal regulations, for example the Renewable Energy Sources Act (EEG) in Germany, can call for permanent
limitation of active power feed-in for your PV system - that is, a limitation of the active power fed into the utility grid to a
fixed amount or a percentage share of the installed nominal PV system power.
The SunnyHomeManager monitors the active power that is fed into the utility grid. If the active power feed-in exceeds
the prescribed threshold, the SunnyHomeManager will limit the PV generation of the PV and hybrid inverters.
SunnyHomeManager in systems with self-consumption
Self-consumption means that the energy produced by your PV system is consumed at the site where it is generated.
Self-consumption reduces the amount of energy that you feed into the utility grid, but also the amount of energy that
you purchase from your grid operator.
Energy Management - Monitoring and Forecast
Creation of a PV generation forecast - based on the location-based weather forecast
Creation of a load profile - based on individual analysis of time-dependent energy consumption:
Taking into account different electricity prices, the SunnyHomeManager makes recommendations for the prudent use
of electrical energy. This allows you to selectively switch on loads at times when electricity is cheap (loads include, for
example, home appliances such as dishwashers, dryers, washing machines, as well as heating and hot water
preparation via heat pumps, and heating elements, but also charging stations for e-mobility).
To learn the load profile, the consumption data should be available over a period of at least 2 weeks.
The forecast generated by the SunnyHomeManager is calculated from the estimated energy balance from generation
and consumption for the next 48 hours.
Optimized self-consumption through load control
The SunnyHomeManager measures the power consumption of all connected loads and records both the power
consumption and the usage time of a load. The SunnyHomeManager uses this individual load profile combined with
the location-based weather forecast to support your increased self-consumption:
To control loads, there are the following options:
• Control of loads that do not communicate directly via switching devices such as radio-controlled sockets or relays,
e.g. Modbus devices that control the SG Ready interface of loads
• Control of directly communicating loads via the standard protocol interfaces EEBus or SEMP
The SunnyHomeManager switches home appliances on automatically when PV energy is available.
