The FOX ESS 11.4kW Hybrid Inverter w/RGM & APS (part number FXESS 30-139-1133F-00, often associated with models like H1-11.4-US or PowerQ AIO series) is a high-performance, split-phase hybrid inverter tailored for the North American residential and light commercial solar storage market. It integrates seamlessly with FOX ESS’s PowerQ All-in-One (AIO) energy storage systems, supporting high-voltage LiFePO₄ batteries like the EQ4000 modules for efficient, scalable backup power and energy management.This inverter excels in grid-tied, off-grid-capable, and hybrid applications, offering robust backup during outages, PV self-consumption optimization, time-of-use shifting, and generator integration (via compatible hubs like Fox Smart Hub G2).Key Features Rated Output Power: 11.4 kW continuous (split-phase 120/240V AC, 60 Hz), with max apparent power up to 17.1 kVA (or 12.54 kVA in some battery-limited modes). PV Input: Up to 22.8 kW max solar STC power, 600V max input voltage, 3 independent MPPT trackers (typically MPPT1: 2 strings, MPPT2&3: 1 string each), MPPT range ~80–550V for flexible array design and high oversizing potential. Hybrid Functionality: Supports both DC-coupled (direct PV-to-battery) and AC-coupled configurations for maximum system versatility. Battery Compatibility: Optimized for high-voltage LFP batteries (e.g., FOX ESS EQ4000 series), voltage range ~80–550V, enabling high round-trip efficiency (>96–97% CEC/PV efficiency). Supports modular stacking (e.g., 2–5 EQ4000 modules per unit for 8–20 kWh per PowerQ, scalable to multiple units up to ~80 kWh total). Backup & Off-Grid Capability: Seamless whole-home backup with fast transfer, high surge handling (e.g., LRA up to 110–160A depending on battery config), and support for imbalanced loads. RGM & APS Integration: Includes Revenue Grade Metering (RGM) for precise energy monitoring and export compliance, plus APS (likely referring to advanced protection/switching or Automatic Power Source features, often bundled with Tigo/APS rapid shutdown transmitters for NEC compliance and safety). Protection & Durability: Built-in AFCI/GFDI arc-fault and ground-fault detection, Type II AC/DC SPDs (surge protection), heated battery support for cold climates, Type 4X enclosure rating for outdoor installation, wide operating temperature (–10°C to 55°C with derating above 40°C), natural convection cooling, and low noise (<35 dB). Efficiency & Performance: Up to 97.5% CEC efficiency, <25W nighttime consumption, <3% THDi at rated power. Monitoring & Communication: Remote access via FOX ESS app/web portal, Wi-Fi 4G (optional), LAN, RS485, CAN, Meter/CT integration, SunSpec protocol support. Certifications: UL9540A, UL9540, UL1973, UL1741 SA/SB/CRD, IEEE1547, Rule 21, HECO SRD-V2.0, FCC Part 15 Class B, and more for grid-interactive reliability. Installation: Plug-and-play design with integrated inverter base, ground-mount, modular scalability (up to 4 units paralleled), and compatibility with accessories like Fox Hub G2 for generator auto-start.Ideal ForHomeowners in areas like California seeking a powerful, code-compliant hybrid solution for large solar arrays, whole-home backup (including high-startup loads), NEM compliance with RGM, rapid shutdown (via APS/Tigo), and future-proof expansion. Its integration with the EQ4000 LFP batteries ensures long cycle life, safety, and high usable capacity in PowerQ AIO setups.For the latest specifications, firmware updates, or detailed wiring/installation guides, consult the official FOX ESS US datasheet (e.g., US-PowerQ-AIO or US-H1-AC1 series) or contact a certified FOX ESS distributor/installer.
