How to monitor photovoltaics and electricity consumption?

Added: Tuesday, 12/16/2025


Installing a heat pump powered by a photovoltaic system is a reliable and proven way to reduce electricity bills and improve air quality. Many investors also value the fact that they are contributing to slowing down climate change. However, the heat pump's electricity consumption can be reduced even further. However, to make this possible, it is necessary to continuously monitor and analyze energy consumption. The FOX ENERGY 3 energy consumption monitor will be of great help in this task.

FOX Energy 3 Wireless Electricity Monitor

FOX Wi-MEF-3 is a network parameter monitor. The device can support single- or three-phase networks and offers bilateral operation and 4-quadrant functionality. The only requirement for using the system is access to a Wi-Fi network and the Internet. Energy consumption is measured using three compact current transformers. Thanks to its small size, Wi-MEF-3 will fit even in a small switchboard, and its installation does not require laborious disconnection of wires. Installation will be even easier thanks to the fact that the transformers have an open core.

How to pay less for electricity?

In many cases, the energy produced by the photovoltaic installation is insufficient to meet the demand of the pump and other devices operating on a given farm. It is then necessary to draw electricity from the grid. Fortunately, the costs associated with its purchase can be significantly reduced. The most effective way is to choose a favorable tariff and to adjust the operation of the pump and the entire installation to its specifics. By planning the greatest energy consumption at hours when it is the cheapest, we can reduce expenses by up to several dozen percent.

3 Phase Energy Monitor Adjusting the operation of energy receivers requires obtaining data on its consumption and a thorough analysis. Without dedicated solutions, this is a difficult and time-consuming task. It is therefore worth using the FOX ENERGY 3 energy monitor . It offers its users a wide range of functions - primarily:

  • monitoring energy consumption and recording results. Measurements may concern both produced and consumed electricity;

  • analysis of power consumption on a daily, monthly and annual basis;

  • forecasting energy consumption in a given billing period (also in terms of available tariffs);

  • monitoring the most important parameters of the electrical network: power, voltage, current. The system also offers the possibility of saving results;

  • export of measurement results to files in the selected format (csv and excel);

  • share results in real time with the RestAPI interface.

Electricity monitoring

WI-MEF-3 is the perfect solution for homeowners looking for a way to effectively monitor energy consumption. If you already have or plan to install a photovoltaic system, the device and the entire FOX system will provide benefits such as:

  • intuitive operation;

  • access to state-of-the-art solutions such as timers, integration with Google calendar and astronomical functions;

  • highest level of security;

  • Wi-Fi failure protection thanks to direct Bluetooth connection;

  • modular design and possibility of expanding functionality;

  • a wide range of control methods (e.g. voice, manual buttons on the wall, mobile app or F&F cloud);

  • compatibility with many devices and systems – e.g. lighting, network sockets, household appliances and electronics, blinds and roller shutters, gates, etc.

The Fox Energy system is distinguished by, among other things, the function of selecting the main tariff for settling energy consumption and conducting a detailed analysis with simulation. Thanks to it, the user can assess what bills he would pay after switching to a different tariff. This gives the possibility of reducing electricity costs and adjusting the tariff to his lifestyle and energy consumption during the day. Importantly, all measurement data is saved on servers in Poland. The user can access them at any time using a free mobile application for Android and iOS systems or a website supported by any browser.
