In 2025, as China’s “14th Five-Year Plan” for renewable energy development approaches its conclusion, the photovoltaic (PV) industry is entering a new phase of technological iteration and market restructuring. During this time, advancements in photovoltaic technology have become a focal point, with efficiency, intelligence, and adaptability to diverse scenarios emerging as key themes. Leveraging twelve years of experience and over one million units sold globally, GoodWe has launched the fourth generation of its classic SDT series, redefining standards through innovation and responding to the demands of the new policy era, thus contributing significantly to the global carbon neutrality process.
The SDT G4 series builds on the legacy of its predecessors. Since the introduction of the first generation of the SDT series, GoodWe has earned user trust with its reliable, efficient, and intelligent product features, leading the global residential photovoltaic market. Over the past twelve years, the stable operation of over one million devices has showcased the remarkable performance of the SDT series in global power stations. The newly upgraded SDT G4 series not only retains the core advantages of earlier models but also achieves comprehensive breakthroughs in performance, design, compatibility, and intelligence.
The SDT G4 series emphasizes an exceptional user experience through thoughtful design, focusing on three core aspects:
- Quiet Enjoyment of Green Living: With optimized heat dissipation structures and proprietary noise reduction technologies, the operating noise is reduced to below 45dB, allowing users to enjoy a peaceful environment even when installed in a garden.
- Lightweight and Flexible Use: The overall size of the unit is reduced by nearly 30%, and its weight is decreased by 32%. This lightweight design facilitates easy installation, especially in challenging roof structures or confined spaces.
- Simplified Maintenance Experience: Featuring a snap-on AC protection cover design, installation and maintenance are expedited, significantly lowering the long-term operational costs, ensuring that the photovoltaic system is efficient and easy to manage.
In terms of performance, the SDT G4 series maximizes the potential of every ray of sunlight. It addresses the global trend of increasing photovoltaic module power and diverse application scenarios with cutting-edge technology:
- Unmatched Adaptability: With a maximum string input current of 21A, it fully supports large silicon wafers and high-efficiency modules such as 182, 210, and 210R, ensuring compatibility without limits.
- Comprehensive Coverage of Complex Scenarios: The design incorporates up to three MPPTs, allowing for flexible integration of components with different orientations, angles, and specifications, effectively overcoming shading and multi-faced installation challenges to maximize each module’s energy output.
- Enhanced Energy Efficiency: Through optimized topology and intelligent temperature control technologies, the conversion efficiency reaches 98.7%, with an IP66 protection rating that ensures stable output in harsh environments, delivering high returns over the product’s lifecycle.
GoodWe has also infused the SDT G4 series with smart capabilities, driven by the dual pressures of carbon neutrality goals and digital transformation, to reduce system costs and accelerate the intelligent management of energy:
- Dual Channel Communication Architecture: The design features dual 485 communication interfaces that fully support various requirements, allowing for multiple solutions tailored to different regional markets.
- Aluminum Wire Compatibility: This feature allows for aluminum wire connections, helping users save on cabling costs while ensuring safety, thus providing a cost-effective solution for power stations.
- Intelligent Safety Ecosystem: Supporting AFCI 3.0, it mitigates over 90% of fire risks caused by DC measurement faults. The power station connects to GoodWe’s intelligent energy management platform, enabling remote monitoring, fault diagnosis, and energy prediction, providing users with a seamless smart maintenance experience through a mobile app.
GoodWe adheres to a customer-centric philosophy, focusing on quality control at the source of inverter production to minimize excessive service in the long run, ensuring customer satisfaction. The SDT G4 maintains GoodWe’s commitment to ultra-low noise design, prioritizing not only energy generation but also the quiet operation of power stations, enhancing the quality of life for surrounding communities. In the event of after-sales issues, GoodWe’s rapid service ensures that the power generation remains uninterrupted, allowing customers to enjoy a “zero-carbon” lifestyle without hassle.
As distributed photovoltaics accelerate into a new cycle characterized by refined scenarios and widespread technology, GoodWe once again sets a benchmark in the residential market with the SDT G4 series. Looking ahead, GoodWe will continue to introduce more innovative and competitive products to meet the growing market demand and contribute to the global energy transition.
