GoodWe GW10K-ET-20 (G2)

GoodWe GW-ET-20 (G2) inverters are modern, three-phase high-voltage hybrid inverters designed for residential installations and small commercial facilities with high energy demand and a high need for power supply reliability. They are available in a rated power range from 6 kW to 15 kW, equipped with 2 or 3 independent MPPT circuits, which ensures high design flexibility even in the case of complex roofs or different PV module orientations.

Key features and benefits

• Hybrid design – enables integration with energy storage systems (HV), allowing for maximized self-consumption, increased energy independence, and emergency power supply (UPS function with <10 ms switching).

• High efficiency – maximum efficiency up to 98.2%, European up to 97.5%; possibility of oversizing on the PV side up to 160–200% and support for high input current (up to 16 A per string).

• Design flexibility – 3 independent MPPTs allow for optimal PV panel placement, even in difficult installation conditions.

• Advanced operating modes – intelligent energy management, support for car chargers, Smart Home devices (SG Ready), and remote monitoring and management capabilities.

• Built-in safety features – Type II surge protection (AC/DC), arc fault detection (AFCI), IP66 protection class, passive cooling, and quiet operation.

• Grid stabilization – a unique feature that transfers PV production to phases with lower voltage if excessive voltage is detected on one of the phases, preventing the system from shutting down when the grid voltage is high.

• Easy expansion – the ability to connect up to four units in parallel and compatibility with a wide range of HV batteries (including GoodWe Lynx D), allowing for flexible increases in energy storage capacity.

• Simple installation and modern design – compact, lightweight housing, built-in smart meter, wide range of communication options (RS485, CAN, WiFi, LAN, Bluetooth).

Summary

The GW-ET-20 (G2) series stands out from the competition with its high efficiency, design flexibility, wide compatibility with energy storage systems, and extensive safety and energy management features. It is the ideal choice for users who expect reliability, high self-consumption, and readiness for future integration with smart homes and electromobility.
