GoodWe Battery Overview (Australia)
GoodWe batteries are lithium iron phosphate (LFP) energy storage systems built for residential and small commercial solar setups. They store excess daytime solar power for evening use or grid outages, and they pair natively with GoodWe hybrid inverters.
GoodWe battery systems capture surplus solar energy so homes can rely on stored power in the evening or during a blackout. This helps families lower monthly electricity bills and improve energy independence.
GoodWe offers a broad range of storage options for different household needs. It has earned wide trust across Australia thanks to its strong safety profile, flexible modular builds, and seamless synchronisation with GoodWe hybrid inverters.
The main GoodWe storage lineups are listed below, each suited to a different scale of residential or commercial demand.
- GoodWe ESA Series
- GoodWe Lynx Home U Series
- GoodWe Lynx Home F Series
- Upgraded Lynx F G2 Series

- GoodWe Lynx Home F G2 Series: A high-voltage solution with stackable 3.2 kWh modules, scaling from 6.4 kWh up to 230.4 kWh in parallel towers. It uses LFP chemistry with IP55 protection, works with EH and ET hybrid inverters, and its usable energy is rated at 100% depth of discharge, so all 3.2 kWh in each module is available to your home.
Fox ESS Battery Overview (Australia)
Fox ESS batteries are LiFePO4 high voltage storage systems sold in Australia across the EQ, EP, and CQ series. They range from a 4.66 kWh single module up to 97.44 kWh, with a slim design that installs easily in small spaces.
Fox ESS batteries are now very popular in Australia. Their smooth design and easy controls help Australian families cut electricity bills and make the most of their solar power, and they install easily in small spaces without disturbing daily life.
Fox ESS also has a 25-member nationwide team across Melbourne, Sydney, Brisbane, Adelaide, and Perth for local technical support. In addition, Fox ESS has earned a spot on the BNEF Global Tier 1 Energy Storage Manufacturers list, which signals bankability and technical credibility.
Key Benefits of Fox ESS
The key benefits of Fox ESS batteries are modular expansion up to 97.44 kWh, real-time app monitoring, competitive pricing, a compact design, high depth of discharge, and safe LiFePO4 chemistry with an IP65 rating.
The main Fox ESS benefits are listed below.
- Modern Modular Design: Fox ESS battery units combine easily, so storage can grow with your energy needs, from a single 4.66 kWh EQ4800 module up to 97.44 kWh with the CQ7 series.
- Smart Monitoring: The Fox ESS app shows production, storage, and consumption in real time, with remote diagnostics and full control over household energy use.
- Affordable Solution: Fox ESS is generally available at a competitive price point, which suits budget-conscious families that want reliable storage at a lower cost.
- Compact and Stylish Design: Slim, modern units fit neatly into garages or utility spaces and blend into home decor.
- Good Performance: A depth of discharge of up to 100 percent lets homeowners use nearly all of their stored energy, supported by over 95% round-trip efficiency.
- Safe Chemistry and Durability: Non-toxic Lithium Iron Phosphate (LiFePO4) with a fused BMS, DC breakers, and an IP65 rating helps the batteries withstand harsh Australian conditions.
Detailed Overview of Fox ESS Models (EQ, EP & CQ Series)
Fox ESS sells three battery families in Australia: the EQ, EP, and CQ series. All are listed as high voltage storage batteries, with energy ranges from 4.66 kWh for one EQ4800 unit up to 97.44 kWh for a CQ7 system.
The six current Fox ESS models and their energy ranges are listed below.
- EQ4800: 4.66 kWh capacity per unit, scalable to 41.93 kWh, with an IP65 ingress protection rating.
- EQ5500: 10.92 to 49.14 kWh, with high voltage architecture, easy installation, high efficiency, and an expandable system.
- EP11: 10.36 to 41.60 kWh, with a safety-focused design, easy installation, high efficiency, and an expandable system.
- EP12 Plus (w): 11.52 to 46.08 kWh, with the same safety, installation, efficiency, and expansion features as the EP11.
- CQ6: 11.98 to 83.86 kWh, with high voltage architecture, easy installation, high efficiency, and an expandable system.
- CQ7: 13.92 to 97.44 kWh, the largest battery in the Fox ESS Australian range.
Fox ESS CQ Series (High Voltage CQ6 & CQ7)
The Fox ESS CQ series is the brand’s highest capacity battery line, made up of the CQ6 and CQ7. The CQ6 scales from 11.98 to 83.86 kWh, and the CQ7 scales from 13.92 to 97.44 kWh.
The CQ series suits large homes, households with EV charging, and small commercial sites that need far more storage than a typical 10 to 15 kWh setup. Both models use high voltage architecture, easy installation, high efficiency, and an expandable system, so capacity can be added as energy use grows.
The table below shows how the CQ series differs from the rest of the Fox ESS range.
Fox ESS Series | Models | Energy Range |
EQ Series | EQ4800, EQ5500 | 4.66 kWh to 49.14 kWh |
EP Series | EP11, EP12 Plus (w) | 10.36 kWh to 46.08 kWh |
CQ Series | CQ6, CQ7 | 11.98 kWh to 97.44 kWh |
Performance Comparison in Australian Conditions
In Australian conditions, both brands perform strongly. Both offer up to 100% depth of discharge, so nearly all stored energy is usable, and GoodWe adds the longer local track record and the larger maximum capacity.
The four areas that matter most for Australian homes are covered below.
- Efficiency & Output: Both systems deliver strong performance for Australian solar setups. Both GoodWe (Lynx Home F G2) and Fox ESS offer up to 100% Depth of Discharge, so homeowners can use the full rated capacity of the battery they pay for.
- Durability & Climate Suitability: Both brands use robust LiFePO4 technology that handles summer heatwaves and temperature swings across Australian regions. GoodWe, however, has the deeper multi-year track record under harsh local grid conditions.
- Scalability: Both brands are modular and stackable, which makes it easy to expand storage for EV charging or household upgrades. Fox ESS scales from 4.66 kWh (EQ4800) up to 97.44 kWh with the CQ7, while GoodWe Lynx Home F G2 towers scale up to 230.4 kWh in parallel, giving GoodWe more headroom for very large homes and small commercial sites.
- Ecosystem Synergy: GoodWe benefits from native inverter-to-battery integration and unified monitoring in the SEMS portal. Fox ESS relies on its dedicated Fox Cloud app and plug-and-play architecture.
Price Comparison in Australia (Including Installation)
A typical GoodWe home battery costs about $7,500 to $11,000 installed after rebates for a 10 to 12 kWh setup. Fox ESS starts lower, at roughly $6,800 to $10,500 installed, though larger CQ series systems cost more.
In Australia, the GoodWe battery price offers strong long-term value. A typical residential GoodWe system usually ranges from $7,500 to $11,000 (approximate cost) installed after rebates for a 10 to 12 kWh setup, depending on the model and installation requirements.
Fox ESS batteries offer an affordable, budget-conscious entry point into solar storage, with basic setups generally starting around $6,800 to $10,500 installed. Larger systems, such as those built on the CQ6 or CQ7, are priced according to their capacity and installation scope.
While Fox ESS offers an attractive initial price, GoodWe delivers a stronger long-term cost-to-performance ratio and a faster return on investment through its operational stability and integrated inverter efficiency.
Which Battery Should You Choose?
Choose GoodWe for a proven Australian track record, native inverter integration, and the largest scalability. Choose Fox ESS for a compact design, a lower entry price, and CQ series capacity up to 97.44 kWh. Both offer 100% depth of discharge.
Your best pick depends on what matters most to you: long-term track record and hardware integration, or a lower starting price and a compact design. The two options are summarised below.
- Choose GoodWe if you want a battle-tested Australian track record, native inverter-to-battery integration, 100% usable capacity, and room to scale up to 230.4 kWh.
- Choose Fox ESS if you want 100% Depth of Discharge at a lower entry price, a compact and stylish design, a lower entry price, and BNEF Tier 1-backed plug-and-play scalability, with the CQ series available when you need up to 97.44 kWh.
