GoodWe GW50K-ET-10 AFCI

The GoodWe ET50 combines flexible C&I energy storage with smart, efficient operation. Intelligent modes — peak shaving, time-of-use, self-consumption and grid support — maximise energy autonomy and cut demand charges, while 3/4 MPPTs with up to 2× PV oversizing capture maximum yield. Parallel connection scales the system for both on-grid and off-grid setups as needs grow, and paired with the STS Box it provides powerful UPS-level backup for critical loads. Comprehensive safety comes built in — AFCI, integrated DC switch, Type II AC & DC surge protection, residual-current monitoring, reverse-polarity, anti-islanding and remote shutdown. For the best result, pair it with the GoodWe BAT-C battery — a matched high-voltage system that forms a complete, single-source C&I storage solution in a modern, compact design.

The GoodWe ET50 50K is a three-phase hybrid inverter with high-voltage battery support, built for commercial and industrial (C&I) energy storage. It's compatible with a range of battery capacities and uses intelligent operating modes — self-consumption, peak shaving, time-of-use and grid support — to optimise performance across scenarios. Available in 40 and 50 kW with 3/4 MPP trackers, up to 2× PV input oversizing, a peak efficiency of 98.1%, AFCI, integrated DC switch, Type II AC & DC surge protection and IP66 protection. Parallel connection enables seamless on-grid and off-grid expansion, and with the Static Transfer Switch (STS) Box it delivers dependable UPS-level backup switching. Best paired with the GoodWe BAT-C battery for a complete C&I storage system.
