G-Max and G-Max Plus bring high-capacity C&I storage into one scalable range.
The G-Max range is designed for larger commercial and industrial energy storage projects, with integrated cabinet solutions that combine battery storage, intelligent control, safety systems and thermal management.
G-Max provides a 215kWh battery system with 100kW rated output power per unit, while G-Max Plus offers a 241kWh cabinet with selectable PCS options and wider site integration, including PV, grid, backup load and generator connections.
Integrated battery storage, BMS, PCS, safety systems and thermal management.
Built for larger commercial and industrial energy storage projects.
Supports wider project routes including PV, grid, backup load and generator connections.
Supports single-cabinet and parallel cabinet configurations, with system design shaped around the site.
The G-Max & G-Max Plus is designed for larger commercial and industrial environments where energy storage needs to support higher demand, solar integration and long-term energy management. As an all-in-one C&I energy storage system, it brings battery storage, intelligent control, safety systems and thermal management into one outdoor-ready unit.
For example, the G-Max & G-Max Plus can support sites such as manufacturing facilities, warehouses, agricultural estates, large retail premises, commercial solar projects and multi-site businesses.
*Larger EMS-led configurations are subject to project design, site requirements and technical review.
The G-Max Plus is an all-in-one commercial and industrial energy storage system, combining 241kWh storage capacity with up to 125kW output per cabinet. Designed for larger C&I projects, it supports flexible site integration across PV, grid, backup load and generator connections, with EMS-led scalability for larger multi-unit systems.

It’s available via web browser and syncs seamlessly with the Fox ESS app, so you’re always connected — whether at home or on the go.
Feature availability may vary depending on your device and app version.
Commercial battery storage can support more than everyday energy management. With the right system design, controls and metering in place, eligible sites may be able to access flexibility opportunities, support the grid and create additional value from stored energy.
Fox ESS works with partners such as Axle Energy and Capture AI to support smarter battery optimisation, Virtual Power Plant participation and grid services opportunities.
Participation, availability and revenue depend on site eligibility, system configuration, metering, communications and the appointed flexibility provider.
Smart optimisation - forecasting solar, tracking tariffs, and automatically charging or discharging to cut costs, while also enabling participation in grid flexibility services.
Join a Virtual Power Plant that aggregates Fox systems to support the grid and unlock extra value through flexible energy services.
