Fox ESS AI Link EMS Box for 3-Phase Inverter Systems

Fox ESS AI Link: The Scalable EMS Control Hub for Multi-Inverter 3-Phase Systems

The Fox ESS AI Link is an essential component for managing large commercial solar installations using three-phase inverters. Acting as the Energy Management System (EMS) hub, it enables seamless communication, synchronisation, and protocol conversion across up to 30 Fox ESS inverters. Its compact, weather-resistant design makes it suitable for demanding environments and diverse commercial applications.

Scalable Control for Multi-Inverter Systems

Designed with scalability in mind, the AI Link EMS Box can manage up to 30 three-phase inverters in parallel, allowing installers to build out complex systems with ease. It communicates directly with Fox ESS inverters, ensuring synchronised operation, streamlined export limitation, and centralised control over power flow and grid interaction.

• Supports parallel connection of up to 30 three-phase inverters
• Simplifies export limitation and synchronisation across sites
• Ideal for commercial systems scaling from 100kW to multi-MW setups

Compact and Built to Last

With a durable IP65-rated housing and a footprint of just 260 × 192 × 88 mm, the AI Link is designed for flexible wall-mount installation in both indoor and outdoor environments. Its lightweight 2.5 kg build makes it easy to position and integrate with minimal disruption during system upgrades or commissioning.

• Weatherproof IP65 enclosure
• Compact size and low-profile installation
• Lightweight and installer-friendly at just 2.5kg

Efficient Protocol Conversion and Export Control

The AI Link ensures compatibility and communication between different inverters and monitoring systems, acting as a bridge for protocol conversion and enabling more intelligent, dynamic energy control. It’s especially useful in systems requiring export limitation, grid compliance, or integration with Building Energy Management Systems (BEMS).

• Handles protocol conversion between EMS, inverters, and smart meters
• Ensures precise export limitation and grid compliance
• Streamlines commissioning across complex energy systems
