The advantages of the
How to charge your electric car with solar power
For this you need:
- your PV system
- your Amperfied Wallbox connect.solar
- and our meter (Power Meter), which measures the flow of electricity.
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 power?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 demand 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 so-called 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. * Available via SW update as of Q4/2023

Smart app control and simple RFID authorization
It already came up: 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 optimized charging.
- Keep an eye on all current loading data.
- Manage access to your wallbox with activation or deactivation of RFID cards that prevent unauthorized access.
Example phase switching
The external Amperfied PowerMeter is used to measure the power produced by the PV system. If the produced power of the PV system is sufficient to charge the electric vehicle with three phases, no phase switching is required. As soon as the generated power is no longer sufficient for three-phase charging, the solar management integrated in the wallbox automatically switches to single-phase charging. Thus, the electric vehicle is charged without any additional mains supply and the costs for charging the electric vehicle are reduced.
Depending on the current self-consumption and PV surplus, a HEMS decides which
household consumer is provided with the self-generated power. In addition, the
HEMS can control the phase switching of the wallbox. The available functions depend on the HEMS used.
WHY CHARGING WITH SELF-GENERATED SOLAR POWER IS WORTHWHILE
You save 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 just under 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 tons 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 has to 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 than can be used in operation.
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 system, can continue to supply electricity even in the event of a power outage. In addition, you will 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 Finanztip.de. This value is called the electricity production costs.
For one kilowatt hour of grid electricity, on the other hand, you will pay around 47 cents per kilowatt hour, according to the German Association of Energy and Water Industries (BDEW) as of April 2023.
