High-performance inverters engineered for global industrial and residential standards.
The global energy paradigm is shifting rapidly toward renewable sources, and at the heart of this revolution lies the Non-Isolated Inverter, often referred to as the transformerless inverter. Unlike traditional isolated inverters that use a transformer to provide galvanic isolation between the DC source and the AC grid, non-isolated models utilize sophisticated electronic circuitry to manage power conversion. This design results in significantly higher conversion efficiency (up to 98%+), reduced weight, and a more compact footprint.
In mature markets like Europe and North America, transformerless inverters have become the industry standard for residential and commercial rooftop solar installations. The lack of a heavy transformer not only lowers shipping costs but also simplifies installation—a critical factor for large-scale deployments. As a leading manufacturer in China, we have observed a surge in demand from emerging economies in SE Asia and Africa, where grid stability and cost-efficiency are paramount.
Non-isolated inverters now account for over 70% of the global string inverter market due to their superior power density.
Modern factories are integrating these inverters with VFD (Variable Frequency Drive) technology to optimize motor-driven pump systems.
Lower internal heat losses contribute to a longer lifespan and reduced electronic waste, aligning with global ESG goals.
The "AI-Inverter" era has arrived. Today's non-isolated inverters are no longer passive conversion boxes; they are intelligent energy hubs. We are seeing a trend where AI algorithms predict solar yield based on weather patterns and adjust MPPT (Maximum Power Point Tracking) in real-time to maximize output even in partial shade.
Key trends we are pioneering at Guangzhou HanFong include:
Guangzhou HanFong New Energy Technology Co., Ltd. is an audit manufacturer of all kinds of inverter and solar charge controller products. Our factory has been an electrical leader in products since 2013. Specialized in DC to AC power inverters, located in Guangzhou City of China, it is convenient to transport by air or by sea.
With robust research and development and strictly quality control, our products in the global market have been widely recognized and praised. With our inverters, they are used together in off-grid solar systems. We always focus on the efficiency and quality of our products. With 5000 square meters of factory and 150 proficient employees, we are able to undertake demanding OEM and ODM projects. We strictly comply with European standards, and so far our products have earned CE and RoHS certifications.
We mainly manufacture those items to the market: North America, Europe, Africa, South America, Middle East, Asia, and have full experience in OEM service. We have full confidence in achieving your quality level and meeting the specific localized technical requirements of your region.
Our VFD inverters are essential for industrial water pumps and motor-driven machinery, providing precise frequency control to reduce energy consumption by up to 40%.
In regions with unreliable grids, our 10kw-150kw hybrid inverters provide a seamless backup, integrating solar, wind, and battery power for 24/7 energy independence.
Large-scale solar farms utilize our high-voltage non-isolated string inverters to minimize line losses and maximize the Return on Investment (ROI).
As a China-based manufacturer, we offer a unique combination of supply chain vertical integration and rapid technological iteration. Procurement officers from around the world look for three things: Reliability, Scalability, and Compliance. HanFong delivers on all fronts by sourcing tier-1 components and maintaining a rigorous 48-hour burn-in test for every unit leaving the assembly line.
