Key Specifications for FOX ESS Batteries
The high-voltage battery architecture is designed to provide efficient energy transfer and strong system performance.
High-Voltage Technology
Expandable Battery System
Fox ESS uses a modular approach, so battery capacity can be matched to the household’s energy usage and, depending on the system, expanded over time.
High Efficiency
High-efficiency energy conversion means less energy is lost when storing and using electricity, helping homeowners get more usable energy from their solar system.
Designed for Everyday Australian Homes
The systems are suited to households looking to increase solar self-consumption, reduce reliance on grid electricity and have greater control over when they use their stored energy.
