GoodWe GW50KS-MT – 50 kW Three-Phase Inverter with Wi-Fi and AFCI Protection for Commercial Installations

The GoodWe GW50KS-MT is an efficient, three-phase grid-tied inverter designed for medium and large-scale photovoltaic installations, such as industrial facilities, warehouses, PV farms, and public buildings. Thanks to its wide voltage range, up to 5 independent MPPTs, high efficiency, and integrated protections (including optional AFCI – Arc Fault Circuit Interrupter), it ensures safe, stable, and maximally efficient operation of the photovoltaic system.

Key Advantages of GoodWe GW50KS-MT:

High Energy Efficiency – maximum efficiency up to 98.6% and DC oversizing capability up to 150% of power.

Up to 5 Independent MPPTs – greater flexibility in designing systems with various roof orientations or shading.

Arc Fault Circuit Interrupter (AFCI) – increased fire safety as standard or as an option.

Remote Monitoring and App Integration – Wi-Fi, RS485, and extendable with 4G/PLC; mobile app and remote diagnostics.

Safe Operation in Harsh Conditions – IP65 protection class, operating temperature range from -30°C to +60°C.

Fuse-less Design – lower servicing costs and simplified maintenance.

Maximum Input Current of 15 A per String – compatibility with modern high-current PV modules.
