Growatt 125kW Ongrid Inverter

The Growatt 125 kW On‑Grid Inverter is built for large‑scale solar projects such as commercial roofs, solar farms, or industrial buildings where maximum power and reliability are essential. With multiple MPPT inputs, high DC input tolerance, and strong efficiency, it converts large solar arrays into grid‑ready three‑phase power consistently. Its robust weatherproof housing and built-in protection features make it ideal for outdoor installation, while flexible PV string layout and oversizing ability give you design freedom and long-term return on investment.
