How It Works

FoxMind™ EMS: The Intelligence Behind the Hardware

 

FoxMind™ EMS is the intelligent core of the M300, transforming complex energy dispatch into simple solutions aligned with your business objectives. You don’t need to be a power expert—just select your desired goal: save on electricity costs, reduce fuel consumption, or ensure critical power supply

One-Click Business Modes

Stop Wasting Fuel on Low Loads

 

Generators are inefficient at low loads. FoxMind™ runs the genset only at its peak efficiency point to charge the batteries, then shuts it down.

Eliminates "wet-stacking" and carbon buildup

Reduces O&M intervals by 50%+

Ensures quiet nights with "Silent Mode" scheduling

eco-friendly site power

Turn Intermittent Solar into Stable Power

 
 

Connect PV arrays directly to the EnergyPack M300. FoxMind™ buffers solar fluctuations, stores excess energy, and prioritizes clean power usage before starting the generator.

Maximize renewable energy penetration.

Smooth voltage dips caused by cloud cover

Always-On Reliability

 

Functioning as a robust UPS, the M300 detects power loss and takes over in less than 20ms.

Protects servers, control rooms, and labs

Clean, Pure Sine Wave output for sensitive electronics.

A Scalable Microgrid Building Block

 

We give you the tools for unified control, protecting your investment.

Open Platform & Integration

We provide standard protocols (RESTful API, Modbus-TCP) to integrate the M300 directly into your existing rental fleet management software.  
 
 

Standard Protocols

Natively supports protocols such as Modbus-TCP, MQTT, and CAN for easy integration into industrial field networks.   
 
 

FoxCloud™ Remote Management

Provides powerful remote monitoring, data analytics, fault diagnostics, and Firmware Over-The-Air (FOTA) upgrade services to ensure your assets are always operating at peak performance.

Extensive Genset Compatibility

Regardless of your diesel generator specifications—from small single units to large paralleled groups—the M300 can be quickly integrated via preset control modes for plug-and-play collaboration.

Typical Application Scenarios

Construction Site Offices

HVAC, lighting, and IT systems running 24/7 Provide clean, silent power for urban infrastructure projects

Utility & Microgrids

Stabilize local grids and integrate renewable energy (PV/Wind)

Event & Entertainment

Deliver high-capacity power for large-scale festivals without noise or emissions.

Mining & Remote Industry

Replace or supplement diesel generators in off-grid locations.

Field Hospitals & Clinics

Reliable, quiet power for sensitive environments.

M300 Pro Technical FAQ

How does the M300 Pro differ from the EnergyPack P300? +
The M300 Pro represents a major leap in high-density engineering. While utilizing a similar compact footprint, it delivers a high-performance 450kVA rated power and a massive 474.24kWh usable energy. It is equipped with an industrial-grade intelligent liquid cooling system and the FoxMind™ EMS, making it the "Pro" choice for demanding industrial microgrid orchestration.
Can it protect sensitive equipment during power transitions? +
Yes. The M300 Pro provides UPS-grade seamless switching (<20ms). This ensures that critical loads—such as data centers, servers, and hospital backups—remain uninterrupted during grid failures or transitions between energy sources.
What are the fuel optimization capabilities for off-grid sites? +
Utilizing FoxMind™ Fuel Saver Mode, the M300 Pro can reduce total energy costs by 30%–80%. It enables Silent Run by shutting down gensets during low-load periods and manages the generator to always operate within its optimal fuel-efficiency range.
Is the M300 Pro built for harsh mining or construction sites? +
Absolutely. It features an IP54-rated (IP65 optional) high-strength weathering steel canopy. With an operating range of -20°C to +50°C and UN 38.3 vibration resistance, it is specifically designed for the rugged conditions of Australian mining, remote infrastructure, and large-scale industrial sites.
Does it support third-party platform integration? +
The M300 Pro is an Open Energy Platform. It natively supports Modbus-TCP, MQTT, and CAN protocols, and provides a standard RESTful API. This allows seamless integration with your existing SCADA systems or asset management platforms for professional-grade fleet monitoring.
