About Fox ESS Battery in Australia
The Chinese energy technology firm with manufacturing facilities for solar inverters and energy-storage systems and EV charging solutions is called Fox ESS. One of the biggest stainless steel manufacturers in the world, Tsingshan Group is a parent concern of Fox ESS, thereby giving the company leverage to scale its operations all over Asia, Europe, and Oceania.
In 2021, Fox ESS penetrated the Australian market with solar inverters. In 2022, their first battery was Clean Energy Council-approved; therefore, they are relatively recent entrants in the solar and battery market. Fox ESS have now listed a local office in Springvale, Melbourne, on their Australian website. The Fox ESS batteries in Australia are smart and modular LiFePO₄ energy storage setups meant to supply energy to homes for some functions, which helps reduce electricity expenses by storing solar energy and using some during power outages or energy independent.
They have earned a reputation for LiFePO₄ chemistry able to safeguard and last along with a modular design that is high voltage and flexible, with scalable capacity ranging from a single module of about 10 kWh to 32 kWh or more. The systems are rated IP65, which means installation can be done indoors or outdoors; cost-wise, they are quite affordable with government rebates available; remote monitoring through mobile apps is quite convenient-as such, the batteries are heavily favored in Australia.
Fox ESS Battery Range and Options
The EQ Series and EP Series from Fox ESS have a lot of different high-voltage, stackable lithium iron phosphate (LiFePO4) batteries. The Clean Energy Council (CEC) has approved both ranges, which means they are safe, reliable, and meet Australian standards. These batteries are mostly made to work with Fox hybrid inverters, but some models can work with other systems as well.
Fox ESS EQ Series – High Voltage Storage Battery
The EQ Series is Fox ESS’s top-of-the-line high-voltage modular battery system. It can be used in both homes and businesses and is designed to be flexible and scalable. Each setup has a Control Module (CM) and 2 to 9 stackable battery modules. Each module has a capacity of 4.66kWh, so the storage can grow to almost 42kWh in one stack. The EQ Series is built to last and work well. It has a 100% depth of discharge, an IP65 protection rating for use indoors and outdoors, and natural convection cooling (no fans). While expansion is possible, new modules must be within 0.5V of existing units and have been recharged in the last five months in order to comply with the warranty. This makes upgrades technically possible but a little tricky. It is DC-coupled and must be used with a Fox ESS hybrid inverter that works with it. The brand now has models that work with the EQ batteries and can handle up to 10kW single-phase and 15kW three-phase.
Key Features:
- 4.66kWh capacity
- Scalable to 41.93kWh
- 100% Depth of Discharge
- Large temperature tolerance
- CAN communication

Fox ESS EP Series – Floor or Wall-Mounted Batteries
The EP Series is a compact, wall-mounted battery solution that combines the battery modules and Battery Management System (BMS) into a single enclosure, making installation simple and space-efficient. The EP5 is a high-performance, scalable battery storage system designed for maximum flexibility, making it suitable for a wide range of energy storage applications. Multiple units can be connected in parallel, expanding the total storage capacity to 20.8kWh.
The EP11 is a high-performance, scalable battery storage system, allowing for maximum flexibility, making it suitable for a broad range of storage applications. Additional batteries can be installed in parallel allowing for a maximum storage capacity of 41.6kWh. While expansion is possible by adding additional EP units in parallel, this setup requires a junction box and generally proves to be a more costly and space-demanding option compared to the modular EQ Series.

What Makes the Fox ESS Battery a Top Contender for Australian Homes?
Choosing a solar battery goes beyond just capacity. It’s about efficiency, durability, and a system that can adapt to your evolving needs. The Fox ESS Battery checks all these boxes with its cutting-edge design and robust performance.
- Exceptional Efficiency: With a round-trip efficiency of over 95%, the Fox ESS Battery minimizes energy loss during charging and discharging. This means more of your self-generated solar power is actually used by your home, leading to maximum savings.
- Modular & Scalable Design: One of the key advantages of the Fox ESS Energy Cube (ECS series) is its modular, stackable design. You can start with a base capacity (e.g., 5.12 kWh) and easily add more modules later as your energy demands grow—a perfect solution for future-proofing your property.
- Built Tough for Australian Conditions: An IP65 rating means the battery is dust-tight and resistant to water jets, making it suitable for both indoor and outdoor installations. Its advanced LiFePO₄ (Lithium Iron Phosphate) chemistry is known for its safety, long life, and thermal stability—crucial for Australia’s diverse climate.
Comparing the Fox ESS Battery: Performance and Value
When you’re comparing a home battery storage Australia solution, you’re likely looking at major players. The Fox ESS Battery offers a distinct value proposition. While premium brands like the Tesla Powerwall and LG Chem have a strong reputation, Fox ESS provides comparable efficiency and a robust warranty at a more accessible price point. Its 10-year warranty and impressive 6,000+ cycle life ensure a long-term, reliable investment that delivers a quick return.
