Sungrow secures world-first VDE FNN prototype certification, granting access to Germany’s inertia market
Executive summary: Sungrow received VDE FNN prototype certification for its grid‑forming inverter, granting the first market‑access “passport” for the German inertia market. The certification enables Sungrow to offer grid‑forming services that stabilize grids with high renewable shares, opening a revenue stream in a key European market.
Who is involved: Sungrow (certificate holder), VDE FNN (certifying body), German transmission system operators (market participants).
Likely next: Sungrow will commence commercial sales of the inverter in Germany and seek similar certifications in other EU member states during 2027‑2028.
Sungrow has obtained the VDE FNN prototype certificate for its grid‑forming inverter, earning the first “passport” that allows the device to participate in Germany’s inertia market. The certification validates the inverter’s ability to provide synthetic inertia, a service increasingly required as renewable penetration rises. This milestone positions Sungrow to capitalize on a nascent but fast‑growing market for grid‑forming solutions in Europe.
