Product Description
FoxESS R-G2 Series Three-Phase Grid-Tied Inverter is a flagship product developed by FoxESS (founded in 2019) specifically for large-scale three-phase industrial and commercial PV scenarios. The company specializes in the R&D, production and sales of PV inverters, energy storage inverters, lithium batteries, EV chargers and heat pumps. Leveraging its global technical advantages and full industrial chain layout, it provides stable, efficient and safe energy conversion services for large-scale industrial and commercial distributed PV projects. Covering a power range of 75kW-125kW, this product integrates core functions such as string detection, PID recovery and high-level protection, and strictly complies with national standards including NB/T 32004-2018 and GB/T37408-2019, accurately meeting the high-power and high-reliability requirements of large industrial and commercial scenarios.
Wide Voltage Adaptability: With a startup voltage of 250V, MPPT operating voltage range of 200V-1000V, maximum input voltage of 1100V, and rated full-load MPPT voltage of 550V-850V, it is highly compatible with high-power density, large-size PV modules and large-scale PV arrays. Even in complex environments such as low light and voltage fluctuations, it can stably maintain efficient conversion, minimizing energy loss to the greatest extent.
Ultra-High Conversion Efficiency: Adopting advanced power conversion topology and precise MPPT control algorithm, it achieves a maximum efficiency of 98.6% and a Chinese efficiency of 98.2%, leading the industry. The total harmonic distortion of current (THDi) is <3%, which meets strict grid connection standards and avoids electromagnetic interference to industrial production equipment; the power factor can be flexibly adjusted from 0.8 leading to 0.8 lagging, adapting to grid dispatching requirements and maximizing long-term power generation benefits for users.
Flexible MPPT Configuration: Equipped with 9-10 MPPT channels (2 strings per channel), each MPPT channel has a maximum input current of 40A and a maximum short-circuit current of 50A, supporting independent optimization of multiple string branches. It effectively solves the problem of uneven light caused by shading and complex roof layouts, fully releasing the power generation potential of large-scale PV systems.
Optimized Structural Design: With dimensions of 975×630×360mm and a weight of 90kg, it adopts a robust and compact structural design, supporting floor-mounted installation. It can be flexibly deployed in industrial plant distribution rooms, outdoor equipment areas, large-scale PV project equipment stations and other scenarios, saving installation space and adapting to the layout needs of large industrial and commercial projects.
Modular Expansion & Easy Installation: Adopting a modular design concept, it supports parallel operation of multiple devices, meeting the power configuration needs of large-scale projects from 75kW to MW level. Equipped with MC4-compatible input terminals and OT output terminals, the wiring is standardized and convenient, shortening on-site installation and debugging time, and reducing construction costs and schedule risks.
IP66 High-Level Protection: It has an IP66 dustproof and waterproof rating, with excellent sealing performance and strong corrosion resistance, enabling stable operation in extreme industrial environments such as high temperature, high humidity, coastal salt spray and heavy dust. The operating temperature range is -30℃ to 60℃, and the maximum operating altitude is 4000m, which effectively reduces maintenance costs and extends the product life cycle.
Full-Dimensional Intelligent Detection: Built-in insulation resistance detection and leakage current detection functions; optional string current detection realizes real-time collection of DC current of each PV string, monitoring string connection status and operating performance. It can accurately identify potential faults such as insulation degradation, line leakage and string abnormalities, and trigger timely alarms to facilitate quick troubleshooting.
Comprehensive Fault Protection: Standard with Type II surge protection on DC side and AC side, optional DC arc protection, covering input reverse connection protection, output overcurrent/short circuit protection, overvoltage/undervoltage protection, overtemperature protection, anti-islanding protection and other functions. It builds a multi-dimensional safety barrier to fully protect the safety of equipment, PV arrays, power grids and personnel.
Compliant Quality & Standard Certification: It strictly complies with Chinese national standards such as NB/T 32004-2018 and GB/T37408-2019, and has passed rigorous reliability tests including high-low temperature cycle, salt spray and vibration. The product quality is stable and reliable, meeting the long-term continuous operation requirements of large-scale industrial and commercial PV projects.
Diversified Remote Monitoring: It supports multiple communication interfaces including USB, RS485 and Wi-Fi+LAN, with optional 4G (Bluetooth) module, compatible with LED local display, Wi-Fi+APP and web-based monitoring platform. Users can real-time view core operating parameters such as output power, efficiency and string current, query power generation statistics, and receive fault push notifications, realizing remote and visual management.
Efficient O&M Support: The intelligent monitoring system has functions such as data analysis, fault traceability and batch device management. It can generate customized energy reports for large-scale industrial and commercial projects to help optimize power consumption strategies and load allocation; it supports centralized monitoring of multiple devices and maintenance work order dispatching, reducing the frequency of on-site inspections and lowering labor and time costs.
Low-Consumption & Reliable Operation: Adopting an intelligent air cooling design, it automatically adjusts the heat dissipation speed according to the device temperature, ensuring stable heat dissipation while controlling operating noise; the standby power consumption is only 3.5W, minimizing energy waste during non-power generation periods and practicing the concept of energy conservation and environmental protection.
Strong Load-Bearing & Grid Adaptability: The rated output voltage is 400V (3W+N+PE), with an output voltage range of 320V-480V and a frequency range of 45Hz-55Hz/55Hz-65Hz, adapting to global mainstream industrial grid specifications. The maximum output current reaches 199.3A, which can stably bear the high-power electricity demand of industrial production equipment, ensuring the stable operation of the entire power system.
Powerful Extended Functions: Standard with PID recovery function, it can automatically detect and optimize the PID effect of PV modules, reduce power loss during the module life cycle, and restore system performance; built-in DC switch and multiple protection mechanisms further enhance the safety and reliability of the system.
