The GW8.3-BAT-D-G20 is an 8.32 kWh high voltage battery from GoodWe’s Lynx D G2 series. It can be paired with compatible GoodWe ESA systems and selected GoodWe energy storage inverters, subject to system design and exact model compatibility.

System size, battery quantity, inverter selection, backup scope and switchboard work affect installed cost. Request current pricing so the quote reflects the complete configuration not battery hardware alone.

Use more of your solar

Store available daytime generation for evening cooking, lighting, entertainment and other household loads, helping reduce grid imports when the system is correctly sized and configured.

Strong power capability

The battery is rated for up to 8 kW maximum system input and output, with 12 kW peak output for 10 seconds under specified conditions. Final power depends on the inverter, battery configuration, state of charge, temperature and site design.

LFP chemistry and layered safety

Lithium iron phosphate chemistry, battery management and integrated aerosol fire extinguishing functionality support residential energy storage. Safe performance also relies on compliant installation, correct placement and operation to GoodWe’s instructions.

Built for flexible placement

The IP66 rated enclosure is designed to resist dust and powerful water jets under the relevant test standard. Wall mounted or floor stacked installation is supported, subject to required clearances, environmental limits and Australian installation rules.

Designed to adapt

Compatible Lynx D G2 modules can be incorporated into a larger designed system within GoodWe’s limits. Any initial or future expansion must be checked for inverter capacity, electrical design, firmware, space and installation requirements.

This model may suit households that export useful surplus solar during the day, buy significant electricity after sunset, want to shift solar into evening use, or need selected load backup from a compatible system.

A Simple Battery Sizing Check

Compare your typical evening and overnight grid consumption with 8.0 kWh of usable capacity. Then check whether your solar system regularly produces enough surplus energy to recharge the battery. The best design covers useful loads without leaving excess capacity routinely unused.

Fortune Solar can review bills or interval data, solar production, peak loads, inverter details, phase supply, switchboard condition, available space and future needs such as an electric vehicle or heat pump.

• Energy and site assessment : review consumption, solar, inverter, switchboard, phase supply, location and backup priorities.
• System design and proposal : specify battery quantity, compatible power conversion equipment, backup scope, installation work, assumptions and current pricing.
• Compliant installation : install approved equipment in accordance with GoodWe instructions and applicable Australian electrical and program requirements.
• Commissioning and handover : test the system, configure monitoring and explain operating modes, shutdown, documentation and support contacts.
