TDS-7KW low-frequency pure sine wave inverter
Engineered by Foshan Jinguangyuan Power Technology Co., Ltd.
The TDS-7KW is a high-performance, low-frequency, pure sine wave hybrid solar inverter. It is manufactured by Foshan Jinguangyuan Power Technology Co., Ltd., a National High-Tech Enterprise with over a decade of expertise in renewable energy solutions. As an ISO 9001-certified manufacturer, Foshan Jinguangyuan ensures that its products meet CE, FCC and EMC standards, delivering reliable power conversion technology for residential and small commercial applications. The TDS-7KW is a prime example of this commitment, providing robust off-grid and backup power capabilities for solar energy systems around the world.

At the heart of the TDS-7KW is a heavy-duty toroidal transformer that provides exceptional surge capacity and overload tolerance. This enables the seamless start-up of inductive loads, such as motors, compressors and refrigeration units. Delivering 7 kW of continuous pure sine wave power with less than 3% total harmonic distortion, this inverter ensures a clean and stable AC output, safeguarding sensitive electronics, medical devices and communication equipment. Its low-frequency design guarantees superior reliability and an extended operational lifespan compared to high-frequency alternatives.

The TDS-7KW integrates a powerful 100 A MPPT solar charge controller that maximises energy harvesting from photovoltaic arrays, achieving over 99% tracking efficiency. An additional 20A AC battery charger supports grid or generator input, providing a maximum charging current of 120A. This versatile unit supports seamless switching between three power sources - solar panels, the utility grid and battery storage - ensuring an uninterrupted power supply during grid outages. The intelligent LCD display provides real-time monitoring of voltage, current, load percentage and system status. Comprehensive protection features, including over-voltage, under-voltage, overload, over-temperature and short-circuit protection, ensure automatic safe shutdown under abnormal conditions.
