GoodWe GW50K-ET-10 is a powerful and sophisticated three-phase hybrid inverter belonging to GoodWe’s ET series, specifically engineered for Commercial & Industrial (C&I) energy storage applications. As a high-voltage hybrid model, it intelligently manages solar generation, battery storage, and grid interaction to optimize energy costs and ensure business continuity. With a robust 50kW output and advanced safety features, it represents a comprehensive energy solution for factories, office buildings, and EV charging stations.

Advanced Safety with AFCI 3.0 (Arc Fault Circuit Interrupter)
Safety is paramount in commercial installations. The GW50K-ET-10 is equipped with GoodWe’s cutting-edge AFCI 3.0 technology. Utilizing advanced AI algorithms and a vast arc signature library, it achieves 100% accurate detection of dangerous DC arcs without false alarms. It boasts a rapid shutdown time of less than 0.5 seconds—significantly faster than the industry standard—and offers a detection range of up to 200 meters, providing comprehensive protection for large-scale PV arrays. This is complemented by integrated Type 2 surge protection on both the DC and AC sides.

Reliable UPS-Level Backup Power
To safeguard critical operations during grid outages, the inverter supports seamless transition to backup mode. When paired with the optional Static Transfer Switch (STS) Box, the system provides UPS-level switching (typically under 10-20ms), ensuring that sensitive equipment experiences no interruption in power supply.

High-Yield Design and Flexible Architecture
Designed to maximize energy harvest, the unit features 4 MPPTs (Multi-MPP trackers) with a high input current (up to 42A per MPPT), making it fully compatible with the latest high-power bifacial solar modules (including 210mm and 182mm cells). It supports a 150% DC/AC oversizing ratio, allowing for future PV expansion. Furthermore, its parallel connection capability enables seamless system expansion for both on-grid and off-grid setups, scaling easily to meet growing energy demands.

Intelligent Energy Management
The inverter features a high-voltage battery range of 200-800V, ensuring efficient charging and discharging with a continuous current of 100A. It supports multiple smart operating modes to reduce electricity bills and improve ROI:
Peak Shaving / Load Smoothing: Prevents costly demand spikes by utilizing battery power during periods of high consumption.
Time-of-Use (ToU): Optimizes energy usage by charging from the grid during off-peak low-tariff periods and discharging during peak high-tariff times.
Self-Consumption: Maximizes the use of on-site solar power.

Applications
Small to Medium-sized Commercial & Industrial (C&I) Sites;
Peak Demand Charge Reduction;
Backup Power for Critical Loads (with STS Box);
Integration with EV Chargers;
Grid Support and Self-Consumption Optimization.
