Product Description
FoxESS F-G2 Series Single-Phase Grid-Tied Inverter is a core product of FoxESS, a leading enterprise founded in 2019 specializing in R&D, production and sales of PV inverters, energy storage inverters, lithium batteries, EV chargers and heat pumps. Designed for residential and small-to-medium commercial distributed PV scenarios, it covers a power range of 3kW to 6kW, featuring a dual MPPT design, energy storage readiness, and easy upgrade to a PV-storage integrated system. Backed by FoxESS's global technical strength and strategic cooperation with authoritative institutions like TÜV Rheinland, it delivers stable, reliable and efficient PV energy conversion experience.
Wide Voltage Adaptation: With a startup input voltage of 80V and an ultra-wide MPPT operating voltage range of 80V-550V, it is highly compatible with mainstream large-size PV modules and various module combinations. Even in early morning, late evening low-light conditions or areas with unstable grid voltage, it can quickly start and maintain efficient power conversion, minimizing energy loss during off-peak light periods.
Super High Conversion Efficiency: Adopting advanced LLC resonant topology and high-performance power devices, the MPPT efficiency reaches 99%, maximum overall efficiency hits 97.4%, and Chinese efficiency is 96.8%—surpassing industry average levels. Total current harmonic distortion (THDi) is <3%, which meets strict grid access standards and avoids interference to household electrical appliances. The power factor adjustable from 0.8 leading to 0.8 lagging allows flexible adaptation to different grid requirements, maximizing long-term power generation revenue for users.
Dual MPPT Precise Matching: Equipped with 2 MPPT channels (1 string per channel) and maximum input current of 14A, it perfectly adapts to large-size PV panels, balancing energy utilization of PV arrays and releasing full power generation potential.
Space-Saving Compact Design: Measuring 402×453×148mm and weighing only 14.8kg, the inverter features a slim and sleek wall-mounted design that can be easily installed in narrow spaces such as roof equipment rooms, exterior wall corners of residential buildings, or the utility area of small commercial stores. Its lightweight structure reduces the load on installation brackets, lowering the difficulty of on-site hoisting and fixing for construction teams.
Plug-and-Play Configuration: Modular design enables flexible combination, with plug-and-play functionality and built-in insurance protection. It greatly shortens installation time, reducing construction difficulty and labor costs.
IP65 All-Weather Protection: Boasting IP65 dustproof and waterproof rating, it supports outdoor installation without additional protective facilities. It adapts to -25℃ to 60℃ operating temperature, 0~100% non-condensing humidity, and maximum 3000m altitude, coping with complex regional climate conditions.
Comprehensive Intelligent Detection: Built-in insulation resistance detection, high-precision leakage current detection , and independent string current detection. It can automatically identify abnormal states such as module insulation degradation, line leakage, or string current mismatch, and immediately send alarm signals to the monitoring platform, helping users detect and resolve potential risks before failures occur.
Full-Coverage Fault Protection: Covers DC reverse connection protection, anti-islanding protection, AC short circuit/overcurrent/overvoltage protection, and supports surge protection (DC/AC: Type II), safeguarding equipment, PV modules and power grids.
Compliant Quality Assurance: Adheres to international standards such as EN/IEC 62109-1/2, AS/NZS-4777.2 and CEI 0-21, passing strict certifications from institutions like TÜV Rheinland, ensuring reliable and compliant operation globally.
Multi-Mode Remote Monitoring: Optional LAN/WIFI/GPRS/4G communication modules support dual-end access via the FoxESS mobile APP (available for iOS and Android) and web-based monitoring website. Users can check real-time operating parameters (output power, efficiency, voltage, current), view daily/weekly/monthly power generation statistics, and receive fault push notifications directly on their mobile phones, enabling remote management without the need for on-site patrols.
FoxCloud V2.0 Advanced Platform: Connected to FoxESS's self-developed FoxCloud V2.0 monitoring system, it provides data statistical analysis, automatic fault alarm and historical data traceability, optimizing power generation strategies and reducing O&M costs.
Low-Consumption Quiet Operation: Natural cooling design eliminates fan noise, with operating noise <30dB, not disturbing daily life and work. Standby power consumption is <1W, practicing energy-saving concepts.
Energy Storage Upgrade Capability: Pre-equipped with a standard energy storage interface and compatible with FoxESS's full range of lithium battery products . When users need to switch to a PV-storage system (e.g., to cope with power outages or peak-valley electricity price policies), they only need to connect the battery pack without replacing the inverter, reducing upgrade costs and extending the product's service life cycle.
Global Market Recognition: As a core product of FoxESS, it benefits from the company's global presence and cooperation with international organizations. It has been widely applied in global distributed PV projects, including those in Southeast Asia and Europe.
Full-Industry Chain Support: Backed by FoxESS's complete product ecosystem (covering PV inverters, energy storage systems, batteries and chargers), it provides one-stop energy solutions for users from component selection to system expansion.
From residential PV systems to small-to-medium commercial projects, the F-G2 series integrates high efficiency, easy installation, smart management and safety compliance. With dual MPPT advantages and energy storage expandability, it stands as a preferred choice for distributed PV applications, contributing to global green energy transition alongside FoxESS's commitment to sustainable development.
