Electrical work and groundwork – one point of contact

Wallbox, heating control, network and cameras – plus cable trenches, pits for transformer stations and cable routes on solar farms. One point of contact for electrical work and excavation: less coordination for you.

Charging, heating, networking

Wallbox connection

We check whether your house connection and cables are sufficient and plan the charging station and its connection. With several charging points, load management distributes the power. If you wish, you charge with your own solar power.

Heating control

We develop and program control systems for heat pumps, boilers, buffer tanks and immersion heaters. Your heating then uses your solar power whenever it’s available. Also for hybrid heating and building control systems.

Network & security cameras

Network, radio links and Wi-Fi all the way into barns, halls and plant rooms – so that monitoring and telecontrol run reliably. Plus security cameras for farmyards, buildings and solar farms: we plan, set up and fix faults.

We are a partner of prev.end GmbH from Mönchengladbach. Electrical installation, commissioning and maintenance work is commissioned through prev.end GmbH and carried out under its responsibility.

Excavator & wheel loader

Cable trench, foundation pit, cable route: we dig ourselves.

With a mini excavator and wheel loader we handle the groundwork around your connection and your system – from the cable trench to an outbuilding to the cable route across a solar farm. Dug cleanly and backfilled as agreed. If we are already on site at your system, you don’t need another company for the trench.

Cable connection work

Trenches for the house connection, PV and storage cables, the supply line to the wallbox or the cable to an outbuilding – across yards, lawns and driveways.

  • Backfilling and compacting

Transformer stations

We dig the pit and prepare the foundation for transformer and compact stations. Plus the trenches for cables and earthing up to the station.

  • Dimensions as specified by the manufacturer and grid operator
  • Excavated soil straight onto the trailer – the site stays tidy

Solar farms

Cable routes between module rows, inverters and the transfer station. Plus trenches for data and camera cables – also later in existing systems.

FAQ

Frequently asked questions

Do you also do excavation work on its own?

Yes. We also take on the cable trench to an outbuilding, the pit for a transformer station or a cable route on a solar farm as a separate job. A few photos of the site, the approximate length and depth and the access route are helpful. Before we break ground, we check where cables and pipes are already buried.
