Grid connection planning & engineering for rooftop photovoltaic systems

Technically sophisticated - safely implemented

A precisely planned grid connection is crucial for the successful operation of Rooftop photovoltaic systems. We take over the complete engineering around the Grid connection planning - From the technical design and coordination with the grid operator to the complete realisation of the connection. Our goal: a technically safe, economical and standard-compliant integration of your PV system into the public grid.

Our services at a glance:

  • Technical grid connection planning

    We develop customised connection concepts based on system size, site conditions and grid availability - including the design of cable routes, transfer points, transformer stations and protective devices.

  • Grid compatibility test & registration

    We prepare the necessary documents for grid compatibility tests, coordinate the registration of your system with the responsible grid operator and accompany the entire testing and approval process.

  • Layout of the electrical installation

    From the feed-in point to the inverter: We plan the complete electrical infrastructure of the PV system, including large-scale battery storage or hydrogen storage, tailored to the applicable VDE standards, technical connection conditions (TAB) and individual requirements.

  • Planning of metering concepts & feed-in management

    We integrate legally prescribed and grid-required metering concepts as well as the connection to feed-in management or monitoring systems - for secure and transparent grid operation.

  • Communication with network operators & authorities

    We handle the technical communication with all relevant stakeholders, prepare data and plans professionally and ensure a smooth approval and coordination process.

  • Support until commissioning

    We provide support with the Realisation on site, coordinate technical inspections and accompany the commissioning of your system - including all the necessary certificates, documentation and handovers.

Why with us?

We offer engineeringServices with high technical standards and practice-orientated implementation. Thanks to our experience in grid connection planning for rooftop systems, we ensure that your photovoltaic solution is not only installed, but also successfully connected to the grid - in compliance with standards, economically and future-proof.
