Wallbox: The Key to Convenient and Efficient Home Charging

With a wallbox and the use of your own solar power, you have the possibility to charge your electric car independently from external power sources. With our energy manager Heartbeat, you can optimise the charging times of your electric car, for example by charging it at times with surplus solar power or favorable electricity prices.


4 Reasons to Upgrade Your Home with a Wallbox

1. Affordable Charging with a Solar System

With your solar power system, you can charge your electric car with low-cost solar power. At the same time, you increase your own consumption and shorten the payback period of your solar system. The more solar power you consume, the cheaper it is.

2. Increased Convenience

Prices at the petrol station fluctuate hourly. By using an electric car in combination with your own wallbox, you are independent of petrol stations, oil companies and OPEC (Organisation of Petroleum Exporting Countries) governments.

If you already own an electric car or are expecting one, your own wallbox allows you to start the day fully charged every day. This means you are independent of waiting times and expensive electricity prices at public charging stations.

3. Fast Charging

Wallboxes charge your electric vehicle much faster than a regular household outlet. You can choose between 11 kW and 22 kW. The charging time is approx. 2-8 hours. If you were to charge your electric car via the household socket with 2.3 kW, the charging process would take between 12 and 24 hours.

4. Secure Charging

They are designed with safety in mind, with features such as automatic shut off, overvoltage protection, and other safety features to ensure a safe charging experience.

We decided to go solar for several reasons: for ecological reasons, for political reasons, to be more independent and to please our children.
Zilian Family
I already knew the Göttingen location before it became part of the 1KOMMA5° Group. The team from Göttingen then informed and advised us, so that we decided on a solar system from 1KOMMA5°.
Sybille Fichte
I heard about 1KOMMA5° through a neighbour and in fact another neighbour has now also opted for 1KOMMA5° as a result of the installation at my house.
Dr. Josef Frasunek
We wanted to become more independent. Also from the electricity market. We asked various suppliers and 1KOMMA5° was able to deliver the fastest.
Mecke Family
That was an investment in the future! I want to produce free electricity on my own roof.
Guido Kahlmeyer
I would recommend my friends to think about environmental protection: What can I do personally? For example, buy a photovoltaic system. That way I'm doing something for the environment.
