We installed the 48kW stack at our property and it transformed operations. It handles EV charging and workshop loads reliably and kept us running during a multi-hour outage which reduced our diesel generator use and fuel costs.
Product Details
Fox ESS 41.9kWh Three-Phase Hybrid Energy System with 10kW High-Power Inverter
Take complete control of your energy with the ultimate residential or light commercial storage solution. This package pairs a colossal 41.9kWh high-voltage battery stack with a robust 10kW Three-Phase Hybrid Inverter.
Designed specifically for Australian homes and businesses with heavy loads, high solar generation, and a three-phase connection, this system delivers energy independence from Sydney to Perth.
Key Features
- Exceptional 10kW Three-Phase Output: The powerful 10kW inverter capacity ensures you can run multiple high-demand three-phase appliances—like large ducted air conditioners essential for summers or commercial machinery—simultaneously without stress, keeping power balanced across all phases.
- Massive 41.9kWh Storage: With enough energy to power most large properties for multiple days, this system provides true energy resilience. It is ideal for properties in Victoria and NSW with high nighttime usage or those preparing for extended grid outages.
- Reliable Blackout Protection: Equipped with blackout protection (EPS), this system offers fast-switching capabilities to keep essential loads running during grid interruptions. Whether facing storm season in Brisbane or grid instability in South Australia, your lights and essential appliances stay on.
- High-Speed Charging/Discharging: The 10kW inverter can charge and discharge the large battery bank faster than lower-rated models. This allows you to quickly store excess solar energy and dispatch it rapidly during peak demand times, maximising savings across Australia’s varying energy tariffs.
- LiFePO₄ Safety & Longevity: Utilizes advanced, safe Lithium Iron Phosphate (LFP) technology, featuring a long cycle life (≥6000) and high Depth of Discharge. Built to withstand Australian climate conditions for long-term value.
- Intelligent Energy Management: Compatible with Australian Virtual Power Plant (VPP) schemes and managed via the intuitive FoxCloud App for real-time monitoring and smart optimisation.
