About This Product

GoodWe GW20K-ETA-G20 is a 20 kW three-phase hybrid inverter from GoodWe’s ESA / ETA-G20 energy storage range. It is designed to work with high-voltage LFP battery storage and is suited to solar-plus-battery systems where backup power, load management and future storage expansion are part of the installation brief. This model is intended for larger homes, rural properties and small commercial sites that need more capacity than a standard residential hybrid inverter.

Who This Product Suits

GoodWe GW20K-ETA-G20 suits customers wanting a GoodWe three-phase hybrid inverter for a higher-capacity solar and battery installation. It is a practical option for properties with larger daytime loads, battery charging requirements, or backup circuits that need more output than smaller residential systems can provide. It is best matched to sites where the installer has confirmed grid approval, battery compatibility and the required backup configuration.

Specifications Explained

GoodWe GW20K-ETA-G20 has a 20 kVA maximum apparent power output to the grid and a 20 kVA nominal backup output, making it suitable for substantial three-phase hybrid installations. It uses a high-voltage battery range of 700-950 V, with maximum continuous charge and discharge current listed at 26.7 A and 29.4 A. The PV side provides multiple MPPT inputs with up to 21 A input current per MPPT, helping installers design around modern higher-current solar modules. Communication and monitoring are supported through GoodWe’s smart energy platform, depending on the final system configuration and accessories used.

Summary

GoodWe GW20K-ETA-G20 is a high-capacity GoodWe three-phase hybrid inverter for solar and battery systems that need strong grid output, meaningful backup capability and high-voltage battery integration. It is most appropriate where the job has been properly designed around three-phase supply, battery compatibility, backup loads and local network requirements. For installers, the main appeal is a single GoodWe platform for larger solar storage projects rather than mixing unrelated inverter and battery control hardware.
