GoodWe GW50K-ET-10 50 kW Three-Phase Hybrid Solar Inverter

The GoodWe GW50K-ET-10 three-phase hybrid solar inverter is designed for energy storage solutions in commercial and industrial (C&I) environments, combining high performance with great operational flexibility. Its hybrid architecture allows the integration of photovoltaic generation, batteries, and the electrical grid in a single device, optimizing energy use and improving system autonomy.

Thanks to its intelligent operating modes, this inverter adapts to different scenarios such as self-consumption, peak shaving, time-of-use management, and grid support. It also supports parallel operation to easily expand installed capacity and, together with an additional static transfer system, provides a high level of backup power continuity.
