FoxESS
Tier-1 modular battery storage backed by one of the world's largest industrial groups. Off The Grid supplies, installs and supports FoxESS batteries for homes and businesses that want proven performance at a competitive price point.
Tier-1 storage without the Tier-1 price tag
FoxESS is backed by Tsingshan Group, one of the world's largest industrial conglomerates. That's relevant because manufacturing scale, supply chain control and financial staying power matter when you're picking a battery brand you'll live with for a decade.
Their EQ, EP and CQ series use high-voltage LFP with fanless natural convection cooling, and pair directly with FoxESS hybrid inverters for a system that's designed to work together rather than bolted together. Good reliability, competitive pricing, clean integration.
When the inverter and battery speak the same language
Most system problems trace back to components that don't talk to each other properly. FoxESS batteries and inverters share native CAN communication, matched BMS integration and a single FoxCloud platform covering solar, storage and site consumption.
That means cleaner commissioning, fewer compatibility headaches and a system our installation team knows inside out. For sites already running FoxESS inverters, adding FoxESS storage is the obvious next step.
What we deliver for homes with FoxESS
FoxESS suits homeowners who want a high-voltage, well-integrated storage system - particularly those already running a FoxESS hybrid inverter or planning a new solar-plus-storage system from scratch. Here's what we deliver.
Reduce your bills and use more of your own solar
We configure FoxESS storage to maximise how much of your solar generation your household actually uses - and to charge from the cheapest available energy when solar isn't enough:
- High-voltage architecture delivers over 95% round-trip efficiency, meaning very little energy is lost between charging and discharging
- 100% depth of discharge on EQ and CQ series gives you access to the full nameplate capacity, not a fraction of it
- Modular EQ series scales from 4.66kWh per module up to 41.93kWh per stack - sized precisely to your household load and solar array
- FoxCloud app provides real-time solar generation, battery state and consumption data from your phone or desktop
- CEC-approved for federal and state rebate eligibility, improving the payback timeline from day one
Your solar self-consumption increases, your evening grid bills reduce, and the inverter and battery work together as a single system. See how FoxESS fits into a complete home solar system.
Keep your home protected through outages
FoxESS batteries include EPS backup functionality that keeps your essential circuits running when the grid drops out:
- Seamless EPS switchover keeps lighting, refrigeration, Wi-Fi and key appliances running during grid outages
- High continuous output means the battery can support meaningful household loads, not just a handful of low-draw circuits
- Fanless natural convection cooling means quiet operation - suited to bedrooms, living areas and garages alike
- IP65-rated enclosures handle indoor or outdoor installation in Australian conditions including high ambient temperatures
- 6,000-plus cycle rating and 10-year warranty with defined throughput guarantee covers daily cycling over the full system life
When the grid goes down, your household keeps running quietly and reliably - backed by a system engineered to perform for a decade. See our full home solar battery offering.
Integrated commercial storage with serious scalability
FoxESS commercial systems - including the CQ6 series and H3 Pro inverters - suit small to medium commercial sites where three-phase operation, high capacity per tower and tight inverter integration are the brief. Here's what we deliver.
Cut demand charges and maximise solar self-consumption
We size and configure FoxESS commercial systems to discharge at exactly the right time for your tariff structure and load profile:
- CQ6 towers reach 83.86kWh per stack; H3 Plus inverters support 50-125kW output - suited to offices, warehouses, retail and light industrial sites
- Over 95% round-trip efficiency and 100% depth of discharge mean more of your stored energy is available when you need it
- Three-phase operation with H3 Smart and Pro inverters handles unbalanced commercial loads across phases
- FoxCloud V2.0 provides remote monitoring, VPP-ready integration and grid service support from a single platform
- Pairs cleanly with existing or new commercial solar arrays - DC-coupled integration maximises self-consumption from rooftop or carport generation
Your demand charges reduce, your solar ROI improves, and the inverter and battery work together under one monitoring platform. See our full commercial solar battery offering.
Protect critical operations and scale as you grow
FoxESS commercial systems include EPS backup and a modular architecture that supports staged capacity expansion without replacing core infrastructure:
- Instant EPS backup keeps servers, POS systems, HVAC and production equipment running through grid faults and outages
- Aerosol fire suppression on CQ series models adds an additional layer of protection for commercial environments where safety compliance is a priority
- Add stacks or modules as loads grow, EV fleet charging is introduced, or additional tenancies come on board
- IP65 weatherproof enclosures and fanless cooling suit rooftop plant rooms, outdoor compounds and warehouse installations
- Our commercial electricians handle all switchboard works, three-phase integration and commissioning end-to-end
Your critical operations stay protected from day one, and your storage capacity grows alongside your business without a platform change. See how FoxESS storage integrates with a commercial solar system.

Why Off The Grid For FoxESS
We configure FoxESS systems as a matched inverter-and-battery setup.
The tight integration between FoxESS batteries and inverters is a genuine advantage - but only when both components are specified, commissioned and configured together by someone who knows the platform. That's what our installation process delivers.
We manage the full scope.
Three-phase commercial FoxESS installations involve switchboard upgrades, inverter configuration, grid connection compliance and multi-trade coordination. Our accre
We provide ongoing monitoring and support.
FoxCloud remote monitoring combined with Off The Grid's proactive support means performance issues are identified and resolved before they affect your home or business.
Inverter and battery, working as one.
Get a no-obligation assessment from an Off The Grid specialist - we'll design a FoxESS system around your site and make sure every component is configured to work together properly.

Your Questions, Answered
Do FoxESS batteries only work with FoxESS inverters?
FoxESS batteries are designed for native integration with FoxESS hybrid inverters and perform best in that configuration. For new solar-plus-storage installations, we typically recommend specifying both together for the cleanest setup. If you have an existing inverter from another brand, we assess compatibility during our design process - start at our home solar batteries or commercial solar batteries page.
How does the modular EQ series work in practice?
EQ series modules start at 4.66kWh and stack up to 41.93kWh per tower, with multiple towers combinable for larger sites. You start with the capacity that suits your current load and budget, then add modules or towers as your needs grow. Off The Grid sizes the initial system and plans the expansion path as part of the design process.
What warranty and support comes with FoxESS in Australia?
FoxESS batteries carry a 10-year warranty with a defined energy throughput guarantee. Off The Grid provides ongoing remote monitoring and direct support after installation - performance issues are caught and resolved proactively, not after you've noticed a problem.
