The best wallbox for your solar system


Buy at Amazon


You own a PV system or want to buy one? You have an electric vehicle, but not yet the right wallbox for energy- and cost-efficient charging? You do now.

May we introduce? Our Amperfied Wallbox

You can integrate it quickly and easily into your existing photovoltaic system. The solar management system integrated from Q4/2023 adapts the charging power to the current energy production of your PV system, you avoid drawing from the grid and thus reduce the costs for charging your electric vehicle.

Do you have a Home Energy Management System (HEMS)? Here, too, the connection is possible without any problems in order to charge cost-efficiently, independently and in an environmentally friendly way.

Are you interested? Then we look forward to hearing from you!

How to charge your electric car with solar power

For this you need:

  • your PV system
  • your Amperfied Wallbox
  • and a our smart meter (power meter) that measures the flow of electricity.
In combination, these components enable so-called PV surplus charging. This means that you use surplus PV electricity to charge your electric vehicle that you do not currently need in your home. In this way, you avoid having to draw electricity from the grid or feed it into the grid.

Our power meter measures the PV surplus and forwards the data to the Wallbox so that it automatically regulates the PV surplus charging in ECO mode.

Integrated, clever phase switching

What happens when it is cloudy, the evening hours are approaching and the solar yield is not so high? Do you then have to resort to expensive grid electricity?

No, you don’t have to. Thanks to our integrated, clever phase switching. The integrated solar management* and external power meter** check whether the power requirement of the electric vehicle is covered with three phases and without additional mains supply. If the solar yield is below 4.1 kW, the Wallbox automatically and dynamically switches to single-phase charging.

Your electric car can then be charged with a surplus power of 1.4 kW. The charging process will then take a little longer, but you will always make full use of the available solar power.

Smart app control and simple RFID authorisation

It has already been mentioned: with our myAmperfied app, you can control the wallbox easily and efficiently.

  • Start and control all charging processes.
  • Reduce or increase the charging current.
  • Switch to PV-optimised charging.
  • Keep an eye on all current charging data.
  • Manage access to your wallbox by activating or deactivating RFID cards that prevent unauthorised access.


The external Amperfied PowerMeter measures the power generated by the PV system. If the PV system is producing enough power to charge the electric vehicle using three phases, phase changeover is not required. As soon as the generated power no longer suffices for three-phase charging, the integrated solar management system automatically switches to single-phase charging. This charges the electric vehicle without drawing additional power from the grid, reducing the costs for charging the vehicle.

Depending on the momentary internal consumption and the PV surplus, an HEMS decides which household consumers receive the self-generated power. The HEMS can also control phase changeover for the Wallbox. The available functions depend on the HEMS used.


You protect the environment

The electricity from PV systems is 100% renewable and does not cause any CO₂ emissions. CO₂ is only produced during the manufacture of the system components of a photovoltaic system. However, these emissions can be quickly offset by the subsequent production of completely green electricity.

The Federal Environment Agency has calculated that a photovoltaic system avoids almost 700 grams of CO₂ per kilowatt hour of electricity over its entire lifetime compared to conventional electricity. According to a study by the Fraunhofer Institute, this saved a net 34.9 million tonnes of greenhouse gas emissions in 2020.

Furthermore, the Federal Environment Agency states that photovoltaic systems in Germany pay for themselves in terms of energy after one to two years. After this time, the system has produced as much energy as must be spent on production, operation and disposal. Conventional energy generation plants using fossil fuels, on the other hand, never pay for themselves in terms of energy, since more energy is used in operation than can be used.

You are independent + save money.

Power failure? No problem. A photovoltaic system produces electricity independently of the power grid and, with an emergency power function included in the electricity storage unit, can continue to supply electricity even in the event of a power failure. In addition, you remain unaffected by future energy price developments on the world markets and save even more money in the long run. The sun does not raise prices.

Of course, you have acquisition costs that are often not exactly cheap. But if you take the purchase price of the PV system and divide it by the total expected electricity production, you often get a notional price of between 10 and 16 cents per kWh calculated over 20 years, according to This value is called the electricity production costs.

For one kilowatt hour of grid electricity, on the other hand, you pay around 47 cents per kilowatt hour, according to the German Association of Energy and Water Industries (BDEW) as of April 2023.
