A kWh meter is a device that measures and records the energy consumption of your household or business. It measures the amount of electricity consumed and expresses it in kilowatt-hours (kWh).

A kWh meter measures the amount of electricity consumed and expresses it in kilowatt-hours (kWh). Both the entire consumption and individual items, such as a charging station, can be measured.

The advantage of a kWh Meter is that you gain insight into your energy consumption, allowing you to save on energy costs. By knowing how much and when you use electricity, you can take targeted energy-saving measures.

A kWh Meter is usually placed in the circuit breaker box. This is where the electricity connection from the street enters and where the electrical circuits and main switch are located.

Whether you require a kWh 1-phase or 3-phase depends on the size of your connection and the number of phases used. The difference between a kWh 1-phase and kWh 3-phase is the number of cables entering your home and the indicated connections on your meter box.

kWh 1-phase
Most homes are connected to the electricity grid with a 1-phase connection. This enters the house in a cable consisting of a phase wire and a neutral wire. The difference between the phase wire and neutral wire is the voltage on your outlets. If you have a 1-phase group cupboard, the electricity meter will read 220/230V.

kWh 3-phase
With a kWh 3-phase connection, 4 cables enter. This connection is common in large homes or businesses. It is then possible to allow a higher energy consumption. A kWh 3-phase connection can be easily recognized because 3×220/230V or 380/400V is indicated on the electricity meter.

More information on which phase kWh Meter you need

You can read how much electricity has been consumed on the kWh meter. This is expressed in kWh. It is important to know how to read the meter to monitor your energy consumption.

Most meters have a digital display showing consumption. In addition, you can use the HomeWizard Energy app. You can then easily view your consumption on your phone or tablet and compare it with other periods.

To connect a kWh Meter, you must follow the manufacturer’s instructions and correctly connect the meter to the electrical installation. It is important to use the correct connections and place the meter correctly. Check out our simple step-by-step plan for installing a kWh Meter 1-phase and a kWh Meter 3-phase:

MID certified means that the kWh meter has been approved and complies with the European Measuring Instruments Directive (MID). This means that the meter measures reliably and accurately and is suitable for billing and trade. The HomeWizard kWh Meters are MID certified.

With a digital kWh Meter, you can only view your current electricity consumption or how much your solar surplus is. With the kWh meter in combination with the HomeWizard Energy app, you can view your electricity consumption for more than a year and compare it with other (current) periods.

Yes, data from the kWh Meter can be exported as a CSV file. This allows you to better map your energy consumption and save energy costs.

Do you want to see how much energy your solar panels are generating? You don’t need a different kWh Meter for this. In combination with the HomeWizard Energy app, you will not only gain insight into your consumption but also into how much your solar panels are generating.

A kWh Meter provides insight into your energy consumption and delivery. For a complete picture, a P1 Meter is recommended. With the combination of a P1 Meter and a kWh Meter on, for example, your solar panel group, you will not only see your consumption but also your production, total consumption, and how much solar power you are using directly. With an Energy Socket, you can also gain insight into the consumption of a single device.
