Our Huachen American-type integrated PV inverter and step-up transformer system is a fully pre-assembled, grid-ready solution, engineered to convert solar energy into grid-compliant AC power, step up the voltage to 10kV or 35kV, and feed directly into the utility grid. This all-in-one unit drastically simplifies the system architecture and construction workflow of photovoltaic power plants, eliminating complex on-site integration and shortening project delivery timelines. The compact integrated system houses a high-efficiency photovoltaic inverter, busbar bridge, low-voltage compartment (integrated with communication and power distribution functions), oil-immersed transformer (with built-in load switch and fuse protection), and high-voltage cable compartment, all within a unified, rugged enclosure. Every unit is fully assembled, wired, and tested in our ISO-certified factory, delivered as a complete package for rapid on-site installation and commissioning.
By integrating all core PV grid-tie components into a single enclosure, our integrated solar inverter and transformer system eliminates the need for separate equipment layout, complex on-site wiring, and multi-vendor coordination. This cuts on-site construction time by up to 70%, reduces civil engineering costs, and enables faster grid connection and revenue generation for your PV project.
The American-style structure delivers an ultra-compact, space-saving design that minimizes land occupation for your solar farm, making it ideal for both ground-mounted and distributed PV projects. The integrated layout provides easy access to all core components, simplifying routine maintenance and reducing unplanned downtime.
The oil-immersed transformer is equipped with an integrated load switch and fuse set, providing comprehensive overload, short-circuit, and overvoltage protection for the entire system. This design ensures stable, continuous operation even under fluctuating solar irradiance conditions, extending equipment service life and lowering long-term O&M costs.
The unified enclosure is built to withstand harsh outdoor conditions, with excellent anti-corrosion, dust-proof, and weather-resistant performance, eliminating the need for additional protective buildings and reducing overall project investment.
