Whether pure consumption, rooftop PV self-generation or a combined plant – we deliver the right medium-voltage connection for your site, TAB-compliant and reliable.
Rising demand, an e-fleet, PV on the roof – we size the station so consumption and self-generation fit together today and as you expand.
One station for grid consumption and feed-in of your PV or CHP plant (combined plant).
Proven protection, instrument metering and utility approval for a dependable connection.
Compact station under 10 m², no building permit required in Germany, quick to install.
Handover point to the medium-voltage grid with instrument metering and protection – the basis for higher connection power.
Steps medium voltage down to your operating voltage (400/690 V) – the classic for commerce and industry.
Combines consumption and feed-in – ideal for sites with rooftop PV or storage.
The transfer station forms the tested handover point to the public grid. The transformer converts the medium voltage to your operating voltage (usually 400 or 690 V).
If you run a rooftop PV or CHP plant, the station is designed as a combined plant: consumption and feed-in via a shared, calibrated metering concept – including a power-plant controller for feed-back.
| Connection power | Transformer (guide) | Recommendation |
|---|---|---|
| up to 630 kVA | 630 kVA | Compact station |
| up to 1,000 kVA | 1,000 kVA | Compact station |
| up to 1,600 kVA | 1,600 kVA | Compact + transfer |
| up to 2,500 kVA | 2,500 kVA | Transfer + transformer |
| > 2,500 kVA | multiple units | Transfer + multiple transformers |
Guide values – the exact sizing is determined by the configurator or our engineering team.
Once your power demand exceeds the limits of a low-voltage connection (roughly from a few hundred kW), the grid operator requires a medium-voltage connection via a dedicated station.
Yes. As a combined plant, grid consumption and feed-in of your PV or CHP plant run via a shared metering concept.
We do: TAB review, sizing and utility approval are part of our service.
Compact stations under 10 m² require no permit in any German state. International sites we check separately.
