GoodWe ET 50kW Inverter

The GoodWe ET 50kW Inverter is a high-voltage, three-phase, hybrid inverter for commercial, light-medium industrial, and large residential applications. Designed for both on-grid and off-grid operation, it combines advanced solar generation, battery storage, and seamless backup capabilities into one compact, elegant unit.

When paired with the Static Transfer Switch (STS) Box, it delivers UPS-level switching (<10ms) for critical loads, integrates with diesel generators, and provides unmatched stability in unstable grid environments. With 150% DC oversizing, a 4-MPPT design, and support for high-current PV strings, the system delivers maximum energy yield and a faster return on investment. Its built-in scalability enables expansion from 50 kW to 500 kW through parallel operation.

The ET 50 kW is suited for applications such as peak shaving, load shifting, and achieving complete grid independence.
