Product Description
The FoxESS T-G3 Series Three-Phase Grid-Tied Inverter is a core product of FoxESS, founded in 2019, which specializes in R&D, production and sales of PV inverters, energy storage inverters, lithium batteries, EV chargers and heat pumps. With its full-industry chain layout and global technical accumulation, it has become a benchmark enterprise in the clean energy field. Tailored for distributed PV scenarios like large residential houses, small and medium-sized factories, stores and office buildings, this product covers a power range of 3kW-25kW, with core advantages including wide voltage adaptation, ultra-high conversion efficiency, flexible MPPT configuration and comprehensive safety protection. Relying on FoxESS's strategic cooperation with authoritative institutions such as TÜV Rheinland and passing multiple strict international and domestic standard certifications, it provides users with a stable, efficient, safe and intelligent large-scale PV energy conversion experience, adaptable to power grids and climate conditions in multiple global regions.
Ultra-Wide Voltage Adaptation Range: The startup input voltage is as low as 140V, the MPPT operating voltage range is up to 140V-1000V, and the maximum input voltage can reach 1100V, which is highly compatible with mainstream large-size PV modules, high-power density modules and large-scale PV arrays. Whether in low-light environments in the early morning or evening, or complex working conditions such as grid voltage fluctuations and unstable power supply in remote areas, it can start quickly and maintain efficient power conversion, significantly reducing energy loss caused by low-light periods and voltage fluctuations, and improving the annual power generation of the system.
Top-Tier Conversion Efficiency: Adopting advanced LLC resonant topology, high-precision MPPT algorithm and high-performance power devices such as silicon carbide (SiC), the MPPT efficiency is up to 99.8%, the maximum overall efficiency exceeds 98.6% (industry-leading level), and the Chinese efficiency is 97.8%, with significant energy efficiency advantages in long-term operation. The total harmonic distortion of current (THDi) is <3%, far below the international standard limit, meeting the access requirements of mainstream global power grids and avoiding electromagnetic interference to precision electrical equipment and household appliances; the power factor can be flexibly adjusted from 0.8 leading to 0.8 lagging, which can not only meet the user's power factor compensation needs but also adapt to the grid dispatching requirements in different regions, maximizing the user's long-term power generation revenue and grid compatibility.
Flexible MPPT Configuration: Precise matching configurations are made according to different power segments of 3kW-25kW. The low-power segment (3kW-12kW) is equipped with 2 MPPT channels, and the high-power segment (15kW-25kW) is upgraded to 4 MPPT channels, each supporting 1+1 string access, with a maximum input current of up to 28A. For problems such as uneven illumination caused by complex roof layouts (such as multi-orientation and multi-slope roofs), tree/building shading, and mixed use of new and old modules, it can independently optimize the maximum power point tracking for each branch string, effectively balancing the power generation efficiency of each branch, avoiding the "barrel effect", and fully releasing the power generation potential of the entire PV system, especially suitable for complex array scenarios of large residential and small工商业.
Reasonable and Compact Design: The unified body size is 370×480×183.5mm, and the net weight is divided into 17kg (3kW-12kW) and 20-21kg (15kW-25kW) according to power segments. The structural design is compact and regular, supporting both wall-mounted and floor-mounted installation methods, which can be flexibly deployed in various scenarios such as roof equipment rooms, industrial and commercial plant distribution rooms, outdoor equipment areas, and balcony storage rooms. The lightweight and standardized design reduces the load pressure on the installation bracket, simplifies the on-site hoisting, fixing and wiring processes, and can be installed by one or two people, greatly improving the construction efficiency and shortening the project delivery cycle.
Plug-and-Play and Modular Configuration: Adopting the modular design concept, it supports parallel expansion of multiple devices to meet the flexible expansion of different power requirements; it is equipped with standard plug-and-play terminals and built-in insurance protection, without complex wiring and debugging, and installers can operate after simple training, which greatly reduces the construction difficulty, labor cost and misoperation risk, especially suitable for small工商业 projects with tight construction periods and large-scale promotion scenarios of distributed PV.
IP65 All-Weather Protection and Environmental Adaptability: It has IP65 dustproof and waterproof level, the shell is made of high-strength corrosion-resistant materials, with excellent sealing performance, supporting direct outdoor installation without additional protective sheds or machine rooms, reducing installation costs and floor space. The product can operate stably in a wide working temperature range of -25℃ to 60℃ and a humidity range of 0~100% non-condensing, with a maximum altitude adaptation of 3000m, which can calmly cope with complex climate conditions in different regions such as high temperature and heatwave, severe cold and freezing, high altitude and low air pressure, and high humidity coastal areas, adapting to application scenarios in most countries and regions around the world.
Comprehensive Intelligent Detection: Built-in high-precision insulation resistance detection and leakage current detection, optional string current detection function, real-time monitoring of circuit operation status, component health status and line connection status, accurately identifying potential risks such as component insulation degradation, line leakage, abnormal string current and poor contact, and timely triggering sound and light alarms and mobile phone pushes through the monitoring platform, helping users and operation and maintenance personnel find and solve problems before failures occur, preventing troubles in advance.
Full-Scenario Fault Protection: Constructing a "hardware + software" dual protection mechanism, covering core functions such as DC reverse connection protection, anti-islanding protection, AC short circuit protection, AC overcurrent protection, AC overvoltage/undervoltage protection, over-temperature protection, over-power protection and polarity reverse connection protection, standard equipped with DC/AC Type II surge protection, optional DC switch and DC arc protection, comprehensively responding to various emergencies such as circuit short circuit, grid abnormality and extreme temperature, constructing a full-link safety barrier to protect the safety of equipment, PV modules, power grids and personnel.
Compliant Quality and Global Certification: Strictly following multiple international and domestic authoritative standards such as EN 62109-1/2, BIS IS 16169, BIS IS 16221-1/2, AS/NZS-4777.2, C10/11, EN50549-1, VDE V 0126-1-1 and NB/T 32004, passing a series of certifications such as electromagnetic compatibility (EN 61000-6-1/2/3/4), grid connection and safety regulations. The product quality has passed strict reliability tests such as high and low temperature cycle test, salt spray test and vibration test, ensuring stable and durable operation in long-term use, while meeting the grid access and market access requirements of different countries and regions around the world.
