The cFos Power Brain Wallboxes

The cFos Power Brain wallboxes have the most comprehensive software equipment on the market. You receive the following extras:

Simple commissioning

Connection by electrician -> charging. Configuration via WLAN access point and web browser.

Dynamic load management already integrated

Operate the charging station with other wallboxes (also from other manufacturers) and make optimum use of the existing house connection power.

PV Surplus Charging (Solar Surplus Charging)

Charge your car with the electricity from your solar system instead of feeding it in, e.g. controlled so that no electricity is needed from the grid. Possible with all Wallbox models.

Phase switching between 1-phase and 3-phase charging. Possible with the "cFos Power Brain Solar" models.
Now also with automatic phase switching! * New!

Record and optimise energy consumption!

Clever charging functions

The cFos Charging Manager has useful charging functions such as "wake up car", "let car sleep" and "save battery".

Optimised for the coming variable electricity tariffs

Green charging, cost-conscious charging, smart meter gateway, energy supplier API, etc.

* as of firmware version 1.23.3

Our cFos Power Brain Wallbox is available with 11 kW and 22 kW charging power.

New: cFos Power Brain Solar with additional contactor for phase switching.

Specially designed for solar surplus charging. Can be switched from 3-phase charging to 1-phase charging so that you can use your solar surplus during low solar irradiation.

Eligible for funding under KfW 442 (solar power for electric cars)

What our customers say about us


Andreas B.

I would like to formally thank you and also the company cFos for such customer-friendly action and the smooth replacement of the meters.


Axel L.

The possibility to display graphics and thus visualise the energy flows is great! Thank you for this new possibility!


Markus K.

Thanks again for the great service. I am thrilled.


Harald K.

I am very pleased with the new version 1.16.0 of the firmware. PRAISE!



It's really great how you expand the functions and respond to customer feedback... I know that in the end you can't please everyone... But (no matter how the "PV charging logic" turns out in the end) that's the reason why the second wallbox (for the parking space in front of the house) will also be a cfos and I recommend the wallbox to anyone who asks (or doesn't ask 😉).
