How to Correctly Connect an Electricity Meter to a Balcony Power Plant?

Connecting an electricity meter to your balcony power plant allows you to monitor energy production and ensure your system is properly integrated with your home’s electrical grid. Follow these steps to ensure a safe and correct installation:

Determine the Meter Required

When planning to connect an electricity meter to your balcony power plant, choosing the right type of meter is crucial to ensure accurate energy measurement and compliance with legal regulations.

It’s important to be aware that older electricity meters, specifically analog meters without a backstop mechanism, may not be suitable. These meters can mistakenly count backwards if your balcony power plant feeds more electricity into the grid than you are consuming. This results in incorrect recording of electricity usage and associated costs, which could potentially be considered a criminal offense due to the erroneous calculation of taxes, duties, and levies.

If your current installation includes an analog electricity meter with a turntable (commonly known as a Ferraris meter), it’s likely to be a type without a backstop. Upon registering a balcony power plant, your metering point operator or an appointed electrical contractor will need to replace this meter to accommodate the new setup.

For a balcony power plant, the following types of meters are suitable:

  • Analog Electricity Meter with Backstop:This type of meter has a mechanical turntable but is equipped with a backstop to prevent reverse recording of electricity.
  • Digital Electricity Meter:Modern and efficient, digital meters measure electricity consumption electronically and display it on a digital screen. Almost all models of digital meters include a backstop, making them inherently suitable for balcony power plants.
  • Bidirectional Meter: A specific type of digital meter, the bidirectional meter is designed to measure electricity flow both to and from the grid. This meter is essential if you plan to feed surplus energy from your balcony power plant into the public grid and benefit from feed-in tariffs. It adheres to the VDE standards required for such setups.

Connection and Installation

Once you have chosen your meter, here are the steps to connect it to your balcony power plant correctly, using the high-quality Anker SOLIX Balcony Solar Power System (2*RS40B Panel 410W, Micro Inverter 600W/800W, Balcony Brackets) as an example:

  1. Mount the Meter:Secure the electricity meter to a wall or a designated mount close to your balcony power plant. Ensure that it is easily accessible for readings and maintenance.
  2. Install the AC Disconnect Switch:Place the AC disconnect switch between the electricity meter and the power plant. This switch is crucial for safety, allowing you to cut off the flow of electricity when needed.
  3. Connect the Cables:Connect the phase conductor (L) from the balcony power plant to the corresponding input terminal of the electricity meter. Then you need to connect the neutral conductor (N) from the power plant to the appropriate output terminal of the meter. Ensure all connections are securely tightened to prevent any loose wiring issues.
  4. Set Up Circuit Breakers:Install circuit breakers in your home’s electrical panel to protect the new circuit. Ensure the breakers match the specifications of your balcony power plant and meter.
  5. Connect to the Home Network and Grid:Finally, connect the output from the electricity meter to your home’s electrical system. This connection allows the energy produced by your balcony power plant to be used within your home or fed back into the electrical grid, depending on your system setup.

Set Up the Meter

After installation, configure the electricity meter according to the manufacturer’s instructions. This may include setting up the meter to record and display information such as the amount of electricity generated and any electricity fed back into the grid. It is highly recommended to have a certified electrician or a professional from the power company to inspect the installation and verify that it is up to standard.
