Sungrow secures world-first VDE FNN prototype certification for Germany’s inertia services market
Executive summary: Sungrow obtained the world’s first VDE FNN prototype certificate for its grid‑forming inverter, allowing it to participate in Germany’s inertia services market. The certification unlocks a new revenue stream for Sungrow in Europe’s fast‑growing grid‑stabilization sector and signals to other manufacturers the pathway to compliance.
Who is involved: Sungrow, VDE FNN, German transmission system operators
Likely next: Sungrow will likely pursue full type certification and begin commercial deliveries of its grid‑forming inverters to German TSOs in the second half of 2026.
Sungrow announced that its grid-forming inverter prototype has received the first VDE FNN certificate, granting it access to the German inertia market. The certification validates that the company’s power conversion systems can provide the stabilizing inertia services required by Germany’s transmission system operators under the ENTSO‑E grid code. This milestone positions Sungrow as an early mover in a nascent European market for grid‑forming technologies.
