Fox ESS EQ4800 battery system now available in Australia

Fox ESS has launched its EQ4800 high-voltage battery system in Australia, a product previously available in other markets for some months. The system is designed for a range of residential and commercial applications and is compatible with Fox ESS’s new H3 Smart three-phase hybrid inverter and integrated Stackable AIO unit.

Core Technical Specifications

The EQ4800 uses Lithium Iron Phosphate (LFP) battery cells and has a modular design, with each battery module providing 4.66 kWh of nominal energy capacity. The system is scalable in series, allowing a maximum of nine units to be stacked for up to 41.93 kWh. A key feature is its 100% Depth of Discharge (DOD), making the entire nominal capacity usable.

The operating voltage for a full nine-module stack is 365.4V to 463.7V, with communication handled via CAN interface. Fox ESS states the battery pack has a round-trip efficiency of over 95%.

Physical and Environmental Ratings

The EQ4800 is IP65 rated, making it suitable for both indoor and outdoor installations and in Australia, the system comes with a 10-year warranty, guaranteeing 70% battery retention.

Additionally, ESS News will quote one aspect of the warranty that may be of interest with Fox ESS offering a “high energy throughput”, with “at least 4.2MWh per kWh usable battery capacity to guarantee more than one full battery cycle a day within warranty period.”

Outside of the warranty, other safety features include cell-level protection and a redundant relay design. The unit holds IEC 62619 and UN38.3 certifications.

Fox ESS also released a Stackable All-in-One system for between 3.7 kw and up to 11 kW of storage.
