GOODWE 50000W GRID-TIED / HYBRID INVERTER GW50K-ET

The GoodWe GW50K-ET is a robust 50 kW three-phase hybrid inverter designed for commercial and industrial solar and energy storage systems. With a maximum efficiency of 98.1%, it delivers reliable grid-tied and backup performance, supporting intelligent modes like self-consumption, peak shaving, and time-of-use shifting. Compatible with high-voltage lithium-ion batteries (200–800 V), it integrates seamlessly with the GoodWe Lynx C battery system for a complete energy storage solution. Featuring four MPPTs with eight PV string inputs, it optimizes energy yield in diverse conditions. The GW50K-ET supports parallel connections for scalability and, when paired with the optional STS Box, provides UPS-level backup power with rapid switching. Its IP66-rated design ensures durability in harsh environments, while smart fan cooling maintains quiet, efficient operation. Monitor and manage your system effortlessly via the GoodWe SEMS portal.
