The Fox ESS G-MAX is a turnkey commercial energy storage system delivering 100kW of rated output and 215kWh of lithium iron phosphate battery capacity — all pre-integrated into a single outdoor-rated container. Built for peak shaving, load management, and grid services, it enables smarter site-level energy use while reducing infrastructure cost and complexity.
Designed for industrial-grade performance, the G-MAX system runs on high-capacity 280Ah LFP cells and operates from 672V to 876V. It delivers 100kW continuous power with up to 110kW peak for short bursts. The system is engineered for full lifecycle endurance with over 8,000 cycles at 70% end-of-life. Onboard management includes predictive alarms, energy routing logic, and active cooling — all controlled by an intelligent BMS.
Preconfigured at the factory, the G-MAX ships ready to deploy. All major components — from internal wiring to the control system — are installed and tested before delivery. Onsite setup is plug-and-play, with simple external connections and automatic detection of expansion units. Ethernet is standard, with wireless options (Wi-Fi, 4G, or 5G) and full integration into the Fox ESS Cloud platform for live data access and system alerts.
