Your questions, our expertise

The energy management system uses excess PV power to control the connected loads. This allows the SMARTFOX Pro to make the best possible use of the electricity it generates. SMARTFOX maximizes self-consumption.

The SMARTFOX can charge electric vehicles, heat water, or be used as a load manager. We also offer free monitoring.

Would you like to charge your electric vehicle, heat water, and monitor your entire system? Then you need the SMARTFOX Pro Energy Manager.

If you just want to heat your water and don't need any monitoring features, the SMARTFOX Pro light is the perfect product for you.

Smart sector coupling refers to the integration and control of a wide variety of components—such as water heating, solar power generation, heat pumps, electric vehicle charging stations, and many others—using an energy management system.

The SMARTFOX Pro automatically detects excess energy from your solar power system and prevents it from being fed into the grid by directing it to the appliances in your home that you have previously designated.

For example, you can use the surplus electricity to heat water, thereby storing energy in a cost-effective way. If you compare the costs you would otherwise incur for water heating with the revenue generated by feeding the surplus electricity into the grid, you can save a significant amount of money easily and without any extra effort, and become somewhat more independent of the energy market.

The standard comprehensive package, which in many cases can help your solar power system reach profitability about 10 years sooner, costs approximately €1,500, including installation. In other words, it’s an additional investment that will definitely pay off.

No, there are NO additional ongoing costs for you.

Some licenses are valid for 10 years. You only need these licenses for larger systems (e.g., systems with two or more inverters).

SMARTFOX can control various heating elements in different ways:

Control via the analog output

Depending on the measured surplus, the energy manager’s analog output transmits a 4–20 mA (or 0–10 V) signal to a power controller. This controller is capable of continuously regulating a conventional heating element, thereby making optimal use of the excess energy.

For more detailed information about this control option, the required components, and their specifications, please refer to our manuals.

To the Downloads Section

Control via relay

Conventional heating elements can be activated or deactivated via the built-in relay contacts, depending on the available excess power.

SMARTFOX Ego Heater RS-485

The SMARTFOX Ego Heater is controlled via the RS-485 interface. This requires that the RS-485 interface is not already in use by other devices. No power controller is required for this control method. The Ego Heater is switched on in 500-watt increments up to a maximum of 3500W, depending on the surplus. You can find more detailed information about this control option, the required components, and their prerequisites in the manual.

In principle, it is possible to use the relay contacts with various wireless applications. SMARTFOX acts as a contact trigger here, closing the dry contact once a specified threshold value is exceeded. This signal is then processed by the transmitter/receiver of the selected product.

It is currently not possible to control Wi-Fi-enabled power outlets directly.

SMARTFOX can control a wide variety of devices, such as heating elements, heat pumps, infrared panels, battery storage systems, and household appliances. Various interfaces are available for this purpose (4 relays, analog outputs 4–20 mA and 0–10 V, RS-485, Modbus TCP, and Modbus RTU).

Similar to the control of heat pumps, it is possible to control CHP units using SMARTFOX. If the CHP unit has a potential-free control input, it can be switched via a relay on the SMARTFOX. The energy manager thus sends a recommendation to the CHP unit to switch on when, for example, a large amount of energy is currently being drawn from the grid and the generated electrical energy can therefore be consumed directly within the building. The “load shedding” control behavior of the relays is suitable for this application.

SMARTFOX can provide metering data for the utility connection point for certain inverter manufacturers (replacing smart meters). Dynamic output limitation can then be configured on the inverter. Please refer to the respective inverter manual to determine whether this feature is available.

Compatibility List

In our download section, you'll find all the manuals for compatible manufacturers.

To the Downloads Section

Connection via Modbus TCP/RTU

If the inverter you are using is Modbus-compatible but is not yet available in the download section, SMARTFOX offers a universal Modbus TCP/RTU interface. In this case, the device’s relevant energy and power registers can be entered manually (the manufacturer’s Modbus registers are required). This requires a certain level of technical understanding and basic network knowledge. The installer should perform the configuration.

To the Downloads Section

Alternatively, a SMARTFOX Energy Meter can be connected to the generator’s AC output to measure the power generated. The data is then transmitted in real time to the energy manager via an RS458 signal.

To the Downloads Section

S0 interface

SMARTFOX also offers the option of importing data via an S0 interface. The SMARTFOX Pro is equipped with an S0 interface for this purpose. If multiple S0 signals need to be captured, they can be integrated via a SMARTFOX Meter and transmitted to the energy manager over the network. A SMARTFOX Meter can capture up to five S0 signals.

Battery management is typically handled by the connected inverter. SMARTFOX monitors the data provided.

With some manufacturers and models, it is possible to take full control of the battery management system. This offers various benefits for energy management (for example, consumer priorities can be allocated more flexibly).

The energy manager itself does not store energy. The system intelligently distributes energy throughout the home, utilizing various devices such as hot water boilers, buffer tanks, electric vehicles, or battery storage systems.

The maximum desired/permissible load can be set on the SMARTFOX. If this limit is reached, the connected loads are intelligently reduced.

This is done dynamically (e.g., charging stations) or statically via load shedding.

If certain appliances, such as washing machines, do not transmit their power and energy data directly, their usage can be monitored via a SMARTFOX Energy Meter. Up to 5 meters can thus be connected directly via RS485. It is also possible to integrate any S0 meters into the portal. An S0 input is located directly on the device. If multiple S0 meters are read, they can be recorded via a SMARTFOX Meter and transmitted to the portal.

Yes, provided they have an S0 contact. An S0 input is located directly on the energy manager. If multiple S0 signals are read, they can be captured via a SMARTFOX meter and transmitted to the portal.

There is no defined kWp upper limit for the PV system. SMARTFOX is suitable for systems of all sizes at the 230/400 V level. The device’s available inputs and outputs are primarily designed for use in single-family homes and small and medium-sized businesses.

All certificates, CE markings, applicable standards, and EU declarations of conformity can be found in the product data sheets and user manuals

SMARTFOX is compatible with a wide range of charging stations and controls them via the network or RS485. You can find all compatible charging stations in the compatibility list.

You can find the instructions and compatibility lists for the respective charging stations in the Downloads section. 

The energy manager is typically installed in the main distribution panel or meter distribution panel of the system, since this is where the building’s main power line is measured via a current transformer. Installation in sub-distribution panels is possible, but it is important to note that the required current transformer cable can be extended by no more than 15 meters (to avoid measurement errors).

The included current transformers are installed on the building's power supply line and use inductive measurement to determine whether electricity is being consumed or supplied.

For information on where to install the current transformers, please refer to the relevant installation and operating instructions for the energy manager.

For detailed information on troubleshooting measurement issues, please refer to the manuals.

Open a web browser and enter the IP address 192.168.250.181. You can now access the SMARTFOX via the web interface, configure settings, or control outputs.

No, an internet connection is not required for the energy manager to function. Certain functions, such as controlling battery storage systems, are carried out via Modbus TCP, i.e., over the network. However, an internet connection is required to use the full range of features offered by the free web portal (e.g., changing the charging mode remotely via the app).

SMARTFOX uses TCP port 5000 (LiveView, Settings…) and TCP port 80 (SD card upload; energy and power charts…)

No internet connection is required for basic energy management. If you need to read data from inverters or control a charging station via Modbus TCP, a local network is sufficient. To take full advantage of the free web portal’s features (e.g., changing the charging mode remotely via the app), an internet connection is required.

In general, we recommend connecting the devices directly via an Ethernet cable. If this is not possible due to installation constraints, powerline adapters may be an option. However, since experience has shown that this technology is prone to errors, SMARTFOX cannot guarantee a constant network connection.

As a general rule, we recommend connecting the devices directly via an Ethernet cable. If this is not possible due to installation constraints, Wi-Fi repeaters may be an option.
