Applications of the EnergyManager

Intelligent energy-control for your household

SOLARWATT EnergyManager monitors, controls and regulates all energy flows in the house. This energy management system offers possibilities for a wide range of applications. In addition, the EnergyManager is the ideal partner for MyReserve. You can see the MyReserve battery’s state of charge any time. The EnergyManager enables you to optimize self-consumption of your own solar power.

The possibilities of the EnergyManager grow with the number of appliances connected to the system. Although the "Internet of Things" is on everyone's lips, many household devices can’t yet be "remote-controlled" directly. Wireless sockets close this gap.

Lamps, washing machines or pool pumps - almost every power consumer can be switched on and off with a wireless socket. With the EnergyManager Portal, this can also be done while on the move.

The intelligent sockets can be connected to the EnergyManager in various ways: by connection with WLAN, via the router's WPS function or manually with an app. The only requirement for a successful integration is that the EnergyManager and the sockets are in the same network and the network is reachable via WLAN. The integration in the EnergyManager takes place via its configuration interface in the Smart Setup area.

Switching and operating times of the individual sockets are set in the Control application of the EnergyManager Portal. The number of connected smart switches is unlimited.

Store solar power as hot water

If you are looking for further ways to store and use your solar power besides home battery systems, storing your solar surplus as hot water can be an option for you. This saves heating costs and additionally reduces CO2 emissions for oil or gas heating systems.

This requires a heating rod for example. It can be controlled via the EnergyManager either time-controlled or solar-optimized. Most heating rods require a minimum of energy in order to work. Once this minimum is met, it can then be regulated continuously or incrementally.

Reduce heating costs

Surplus solar power can also be used to operate a heat pump. A heat pump works according to the principle of a refrigerator and extracts heat from the environment to add it to the heating system. In summer, this effect can even be reversed and used for cooling.

If the heat pump is connected to the EnergyManager, it will grant the pump priority of solar surplus. As a result, less grid power is consumed and heating costs are reduced. If a heat pump replaces oil or gas heating systems it additionally saves CO2 emissions.

Charging an electric vehicle

Charging your vehicle with self-generated solar power not only makes ecological but also economical sense: at a cost of just over 2 € per 100 km, this mobility becomes much cheaper than operated with fossil fuels or grid power.

The EV charger is integrated into the domestic network via the EnergyManager. The electric vehicle is preferably charged with surplus solar power in a way that guarantees the battery to be fully charged at a desired departure time. The system’s performance is displayed in the EnergyManager Portal: the average charging load, the average production of solar power and the distance that can be driven with the current state of charge.

Intelligent charging - safe driving

The charging process is precisely defined in the “Control” area of the EnergyManager Portal. In addition to "PV-optimized" charging with surplus solar power, specific charging times can be set, e.g. a quick "backup charge" after returning home from work to ensure a later drive to a defined distance. The EnergyManager uses the power of the PV system or the MyReserve battery. An additional meter for the wallbox is no longer necessary.

The solar optimizer is configured to display the minimum range associated with the corresponding state of charge. This makes it easier for end customers to select the right charging quantity. To further ensure charging, it is favorable to use night tariffs offered by some energy suppliers.

Define switching schedules for consumers

The switching schedules of all consumers can be controlled in the EnergyManager Portal via the clear and intuitive "Control" interface. The operation of each individual consumer can be set to solar-optimized (symbol: sun) or time-controlled (symbol: clock). When active the symbol is displayed in orange otherwise it’s grey.

Simple switching

All connected devices are listed under "Control": first the solar-optimized ones, then the time-controlled ones. The higher a device is in the list, the higher is its priority. This means, that the device listed highest is switched on or charged first if there is solar surplus. The other devices then follow.

New connected devices are automatically detected by the EnergyManager during a short setup and added to the list. Alternatively, consumers can be added via the "Add" button.

Depending on the kind of device, switching can be done continuously or in steps. Setups with switching thresholds are also possible, e.g. for SGready heat pumps and small consumers.

Exceptions confirm the rule

Fixed programs can be overwritten temporarily in the energy management system. After a set duration, the program returns to the automatic mode. This prevents e.g., a pond pump from being continuously switched off.

For wireless sockets that also have a physical switch, the setting "free" enables manual switching. Outside the designated “free” time frames, the solar-optimized switching will automatically take place. This program can also be customized by setting "minimum" or "defined running time" or a "minimum rest time". Dehumidifiers or pond pumps are good examples suited for these features.

Even more possibilities

Typical switching programs can be gathered in profiles. For example, it makes sense to define profiles for different seasons for the heating system.

The extensive functionalities of the EnergyManager Portal are explained in detail in the Help Center where users can find the answers to many of their questions.
