About This Product

The GW8.3-BAT-D-G20 – GoodWe GW8.3-BAT 8 KWH USABLE G20 is an 8.32 kWh lithium iron phosphate battery module designed for GoodWe’s ESA residential energy storage platform. It provides 8.0 kWh of usable energy and forms part of a modular high-voltage battery system that can be expanded as household storage requirements increase. The G20 version also supports low-temperature charging when the optional battery heating function is fitted, making it distinct from the otherwise similar G21 version.

Who This Product Suits

The GW8.3-BAT-D-G20 – GoodWe GW8.3-BAT 8 KWH USABLE G20 suits residential and small-business customers installing a compatible GoodWe ESA energy storage system and wanting approximately 8 kWh of usable storage per battery module. It is particularly useful where a larger modular battery system is planned, as multiple modules can be combined within an ESA installation to increase total storage capacity. It is intended to be installed as part of the compatible GoodWe battery and inverter architecture rather than used as a stand-alone battery with an unrelated inverter.

Specifications Explained

The GW8.3-BAT-D-G20 – GoodWe GW8.3-BAT 8 KWH USABLE G20 uses lithium iron phosphate, or LiFePO4, battery chemistry and has 8.32 kWh of rated energy with 8.0 kWh of usable energy under GoodWe’s specified test conditions. Maximum system charging power is 8 kW and maximum system discharge power is also 8 kW, with peak discharge capability of up to 12 kW for 10 seconds when system conditions permit. Maximum input current is 19 A and maximum output current is 21 A.

The battery operates within GoodWe’s high-voltage ESA architecture, with a specified operating voltage range of 350-550 V for compatible single-phase systems and 700-950 V for compatible three-phase systems. Communication is via CAN, and the enclosure carries an IP66 ingress-protection rating for resistance to dust and water. The G20 model has a specified charging temperature range of -18°C to +55°C where the optional heating configuration is used, while its discharge operating range is -20°C to +55°C.

GoodWe specifies a 10-year limited product warranty for the GW8.3-BAT-D-G20 in Australia and New Zealand. The associated performance warranty provides for 70% of usable energy within 10 years or a minimum throughput of 29.20 MWh, whichever occurs first, subject to GoodWe’s applicable warranty conditions.

Summary

The GW8.3-BAT-D-G20 – GoodWe GW8.3-BAT 8 KWH USABLE G20 is an 8.32 kWh LFP battery module delivering 8.0 kWh of usable storage for compatible GoodWe ESA systems. Its high-voltage architecture, 8 kW maximum charge and discharge power, 12 kW short-duration peak output, IP66 enclosure and modular design make it suited to modern residential battery installations where storage capacity may need to grow over time. System configuration, the required number of battery modules and inverter compatibility should be confirmed as part of the installation design.
