About This Product

GW GW29.999K-ETA-G20 is a GoodWe ESA Series three-phase hybrid inverter power module for high-voltage battery energy storage systems. It sits in GoodWe’s ESA 5-30kW range and is intended for larger residential and small commercial systems that need solar, battery storage and backup capability in one coordinated platform. This model is rated at 29.999kW / 29.999kVA on the grid side and supports high PV input capacity for sites with larger solar arrays.

Who This Product Suits

GW GW29.999K-ETA-G20 suits three-phase properties where the installer needs a GoodWe hybrid inverter for a larger solar and battery system. It is a practical fit for large homes, farms, workshops and small commercial sites with meaningful daytime loads, battery storage plans and a need for backup power support. It is not a small single-phase inverter, so it should be selected only where the site supply, battery compatibility and network approval suit this output class.

Specifications Explained

GW GW29.999K-ETA-G20 uses a high-voltage LFP battery platform with a 700-950V battery operating range and 750V nominal battery voltage. The battery side is rated for 40.0A maximum continuous charging current and 44.1A maximum continuous discharging current, with up to 30kW charging power and 33kW discharging power. On the solar side, it supports up to 60kW PV input, 1000V maximum DC input, a 120-950V MPPT operating range, four MPPTs and a string layout of 1 / 1 / 2 / 2. The grid side is rated at 29.999kW / 29.999kVA, while the backup side is rated at 30kVA nominal apparent power, with GoodWe specifying less than 4ms on/off-grid switching and up to 98.2% maximum efficiency.

Summary

GW GW29.999K-ETA-G20 is a high-capacity GoodWe three-phase hybrid inverter from the ESA Series, built for larger solar and battery installations. It offers four MPPTs, high-voltage LFP battery support, strong PV oversizing capability and a 30kVA class backup output. For suitable three-phase sites, it gives installers a GoodWe option for combining solar generation, battery storage and backup power in a larger energy system.
