Overview
Photovoltaic Power Generation Solution | Jiangsu Huayu Transformer Co., Ltd. For years, we’ve built up deep experience in developing and manufacturing power equipment. Today, we offer full-range PV power generation solutions for utility-scale solar farms, commercial rooftop PV systems, industrial distributed generation, solar-wind hybrid projects, agrivoltaic (agri-PV) projects, fishery-solar complementary projects and smart grid integration. As a trusted PV power equipment supplier, we zero in on the critical part of PV systems: power transmission and conversion. We provide a complete lineup of high-performance core equipment, including PV box-type substations, inverter step-up integrated box-type substations, dedicated PV transformers, distribution transformers and intelligent power distribution units. These products run reliably, handling efficient current collection, power conversion, voltage boosting and stable grid connection. They also help fix the intermittency and volatility issues common with PV power, so your PV equipment works smoothly no matter the environment.
Performance and Environmental Adaptability
Every PV product we make goes through strict optimization, testing and quality checks to meet the tough technical demands of the global PV industry. Our dedicated PV transformers use advanced non-alloy core materials, precision winding technology and anti-DC bias design—they hit Grade 1 energy efficiency and keep losses low. Compared to standard transformers, they cut no-load and load losses by 15%-20%, which means PV power stations save on long-term operational costs and boost power generation efficiency. Our PV box-type substations and inverter step-up integrated substations are highly integrated, take up little space and use modular design. They have protection levels from IP54 to IP65, so they’re resistant to corrosion, dust and moisture—perfect for harsh outdoor spots like deserts, coastal areas, high-altitude regions and humid farmland. These products work steadily in temperatures from -40℃ to 55℃, so they fit the unique environmental needs of any PV project.
Safety and Intelligent Monitoring
Safety is always our top concern when developing and making PV power equipment. Every PV product comes with a full set of intelligent protection features: overload protection, short-circuit protection, overvoltage protection, undervoltage protection, insulation protection and over-temperature protection. If something goes wrong with the equipment, these features kick in fast to cut power, preventing equipment damage, blackouts, fires and other potential risks. Each unit also has an intelligent monitoring system that collects and analyzes real-time operating data—things like temperature, voltage, current, load status and insulation performance—via 4G or optical fiber. This lets you monitor remotely, get early fault warnings and use intelligent diagnosis, which simplifies maintenance work a lot and makes equipment management more efficient, while boosting PV system availability.
Standards and Applications
All our PV power products fully meet international IEC standards, national GB standards, the latest GB/T 46987 standard for PV power conversion equipment and GB/T 46986 standard for PV system testing and maintenance. They’ve also passed ISO 9001 quality management system certification. That means our products work seamlessly in PV projects around the world—whether it’s a large utility-scale solar farm, commercial or industrial rooftop PV system, solar-wind hybrid energy system, or special setups like agrivoltaic, fishery-solar complementary or off-grid PV power supply. We tailor solutions to each customer’s specific power needs, on-site conditions, regional industry standards and project size, so we can meet the diverse needs of PV customers everywhere.
Service and Support
Besides high-quality PV power equipment, Jiangsu Huayu offers end-to-end professional services to customers worldwide. These include pre-sales technical advice, professional scheme design, technical guidance, professional O&M training and 24-hour emergency after-sales support. Our technical team has plenty of experience with global PV projects, and they know the technical standards and project requirements in different regions. They respond quickly to customer needs, providing timely, professional technical support to make sure PV projects finish on time and equipment runs reliably for years.
Application Scenarios
Our customized PV transformers and power distribution solutions are used in all kinds of PV setups: utility-scale solar farms, commercial rooftop PV systems, industrial distributed PV generation, solar-wind hybrid projects, agrivoltaic (agri-PV) projects, fishery-solar complementary projects, off-grid PV power in remote areas and building-integrated photovoltaics (BIPV). Our products offer great overload capacity, wide temperature adaptability, high insulation performance and strong anti-interference ability—they fit the power transmission and conversion needs of any PV scenario. We’re dedicated to providing safe, stable, efficient and low-loss power support for global PV generation, PV-storage integration and renewable energy grid connection. We want to help grow the global renewable energy industry and contribute to low-carbon, green and sustainable development around the world.
