E-mobility · Wallbox

EV charging

We install wallboxes with correct protection, solar-surplus charging, dynamic load management, user control and energy metering.

Solar PV on a residential building

Direct answer

A smart wallbox adjusts charging power to the building’s capacity. The car can absorb solar surplus while dynamic control protects the grid connection.

01

Electrical assessment

We check the contracted capacity, distribution board, cable route, conductor size, earthing and manufacturer-specific protection.

  • Single or three phase
  • Residual-current and overcurrent protection
  • Cable route and installation method
02

Solar charging

An energy meter tracks import and export. Charging power follows the available surplus and the vehicle’s minimum current.

  • Solar and boost modes
  • Priority versus the battery
  • Configurable time windows
03

Manage peak loads

Cooking, heat pumps and charging can overlap. Dynamic control reduces EV power before the main connection is overloaded.

  • Grid-point limit
  • Multiple charging points
  • Reserve for building loads
04

Access and reporting

For businesses and apartment buildings we assess RFID, users, reporting and allocation based on the selected platform’s functions.

  • User authorisation
  • Charging history
  • Provision for expansion

FAQ

Frequently asked questions

Can I charge only from solar?+

Yes, with a compatible wallbox, meter and vehicle. Passing clouds and minimum current can cause pauses or limited grid support.

Do I need 22 kW?+

Not always. Vehicle capability, parking duration and grid capacity determine whether 11 kW is already sufficient.

Can several wallboxes be managed?+

Yes, with compatible dynamic load management and clear rules for the total available capacity.
