About This Product

GW GW15K-ETA-G20 is a GoodWe ESA Series three-phase hybrid inverter for larger residential and small commercial solar and battery systems. It is designed for high-voltage LFP battery storage, solar self-consumption and backup power applications. In GoodWe’s range, this model sits in the ESA all-in-one energy storage family, using the ETA-G20 inverter platform. It is suited to installations where a standard single-phase hybrid inverter is not enough and the site has three-phase supply.

Who This Product Suits

GW GW15K-ETA-G20 suits three-phase homes, farms, workshops and small commercial sites needing a GoodWe hybrid inverter with battery capability. It is a practical option where the customer wants solar generation, high-voltage battery storage and backup capacity from one coordinated system. It also suits jobs with multiple roof orientations, because the four MPPT design gives installers more flexibility when laying out strings. Final suitability still depends on network approval, battery selection, switchboard layout and site backup requirements.

Specifications Explained

GW GW15K-ETA-G20 is rated at 15 kVA maximum apparent power to the grid and 15 kVA nominal backup apparent power. The battery operating range is listed as 700-950 V, with maximum continuous charge and discharge currents of 20.1 A and 22.1 A respectively. The PV input side uses four MPPTs, with 21 A maximum input current per MPPT, which helps support modern higher-current solar modules and more complex array layouts. It is a three-phase hybrid inverter with integrated Wi-Fi monitoring, CT metering support and compatibility with GoodWe ESA high-voltage battery modules.

Summary

GW GW15K-ETA-G20 is a GoodWe three-phase hybrid inverter for larger solar and battery systems where storage, backup and flexible PV design are required. Its 15 kVA output rating, four MPPTs and high-voltage battery operation make it a strong fit for larger residential and light commercial installations. It should be matched with approved GoodWe battery components and installed by a qualified electrician in line with Australian standards and local network requirements.
