GoodWe GW15K-ETA-G20 15kW Three-Phase Hybrid Inverter

The GoodWe GW15K-ETA-G20 is a 15 kW three-phase all-in-one hybrid inverter designed for residential and small commercial energy management. It integrates PV input, battery charging/discharging, and grid connectivity with a UPS switching time under 4 ms for seamless backup power. The inverter features 4 independent MPPT trackers with a nominal voltage of 750 V DC and supports high-voltage LiFePO₄ battery systems including the ESA 5.1 kWh and 8.3 kWh modules.

Key capabilities include IP66 protection rating for outdoor installation, AI-driven energy management, 6-layer safety protection with AFCI 3.0, and support for on-grid and off-grid parallel operation. The system delivers up to 200% DC oversizing, up to 1C charge/discharge rates, and quiet operation with noise below 40 dB. Dual-port design enables whole-home backup with flexible battery mixing of different capacity or mixed-age battery modules.

Rated AC output power is 15 kVA to and from grid, with maximum apparent power of 15 kVA (grid output) and 43.5 kVA (grid input with 63 A internal bypass). Operating temperature range spans –35 °C to +60 °C, supporting reliable performance even in cold climates with integrated heating mode.
