FOX ESS HUB 2.0, FXESS 30-403-00004-B0

The FOX ESS HUB 2.0 (also known as FOX Hub G2, part number FXESS 30-403-00004-B0) is a smart energy management system (SEMS) that serves as the central control unit for FOX ESS residential and light commercial whole-home energy storage solutions, such as the PowerQ All-in-One (AIO) series and US Series hybrid inverters. It integrates grid, backup loads, non-backup loads, generators, and smart circuits into a single, intelligent hub for seamless power distribution, automatic off-grid protection, and optimized energy flow.

This version (w/Smart Circuits & WiFi/LAN) includes built-in smart load shedding circuits for intelligent control of priority loads and an integrated Smart WiLAN module (with optional LAN support via compatible accessories) for reliable remote monitoring and configuration through the FoxCloud US app or portal, enabling features like time-based or SOC-based load management, generator auto-start, and real-time system oversight.

Key Features

• Power Handling: 200A nominal AC current (grid input/output), rated for up to 48 kW AC power, supporting full 200A service entry with 22 kA short-circuit breaking capacity.
• Split-Phase Operation: Nominal 120/240V AC (60 Hz), with backup providing 120V L-N and 240V L-L; frequency range 57–63 Hz (extended 55–65 Hz in backup mode).
• Seamless Transition: Grid-to-backup switchover <20 ms (typically <15 ms) for near-instantaneous UPS-level performance during outages.
• Scalability: Supports up to 4 paralleled FOX ESS inverters (e.g., up to ~45.6 kW total with 11.4 kW units), with automatic load balancing.
• Smart Circuits (Integrated): 1x 240V (80A) and 2x 120V (80A each) controllable smart load shedding circuits for prioritized management—shed or enable non-essential loads (e.g., EV chargers, pool pumps, HVAC) based on time-of-use, battery SOC, or other parameters via the app.
• Generator Compatibility: Optional input up to 48 kW (200A continuous), with 2-wire auto-start dry contact (0.5A at 250Vac / 3A at 30Vdc) for automatic generator activation during extended outages.
• Terminals & Connections: High-current terminals including Solar (80A), Inverter (80A), Non-Backup Loads (200A), Backup Loads (200A), and busbar rating up to 280A.
• Monitoring & Communication: CAN, RS485, Meter/CT (0.5% accuracy for import/export), SUNSPEC protocol; integrated Smart WiLAN for WiFi connectivity (with LAN fallback/support via compatible modules), enabling remote access, firmware updates, and energy optimization through FoxCloud US app/portal.
• Protection & Durability: Type 3R enclosure (indoor/outdoor rated), natural convection cooling, noise <35 dB, operating temperature –4°F to +122°F (–20°C to +50°C), integrated safety features per UL standards.
• Certifications: UL67, UL869A, UL916, UL1741, CSA22.2 NO.107, FCC Part 15 Class B, and more for grid-interactive compliance.
• Installation: Wall-mountable (recommended height ~41 in.), dimensions 26.2 × 17.4 × 6.2 in (665 × 443 × 156.6 mm), weight ~37.4 lbs (17 kg); conduit sizes: 2.5″ for grid/generator (6 AWG–250 kcmil), 1″ for communication (24–16 AWG). Configurable as service entrance panel (with main breaker) or sub-panel.

Ideal For

Homeowners and installers in areas like California requiring advanced whole-home or partial-home backup, smart load prioritization for high-demand appliances, generator integration for resilience, and robust remote monitoring via WiFi/LAN. It pairs seamlessly with FOX ESS PowerQ AIO systems (e.g., 11.4 kW hybrid inverters + EQ4000 batteries) for modular, expandable setups with code-compliant features like rapid shutdown support and precise energy tracking.
