TD-203192 Low-Frequency Pure Sine Wave Inverter
Engineered by Foshan Jinguangyuan Power Technology Co., Ltd.
The TD-203192 is a high-power, low-frequency, pure sine wave inverter manufactured by Foshan Jinguangyuan Power Technology Co., Ltd., a specialist producer of renewable energy products based in the Zhangcha High-Tech Zone in Foshan, Guangdong. With over a decade of industry experience, Foshan Jinguangyuan has built a solid reputation for manufacturing inverters, solar inverters and UPS systems. The TD-203192 is a flagship model within the TD Series, designed for use in challenging off-grid solar installations, industrial backup power systems, telecommunications infrastructure and commercial facilities where the grid is unreliable or unavailable.

At the heart of the TD-203192 lies a robust toroidal transformer that delivers exceptional surge capacity, with a peak power rating of 60 kW - three times its continuous 20 kW output - enabling the reliable start-up of high-inrush inductive loads, such as large motors, compressors, and industrial pumps. Its pure sine wave output achieves less than 3% total harmonic distortion, ensuring clean, stable AC power to protect sensitive electronic equipment and medical devices. Operating at a standard battery voltage of 192 V DC and supporting a wide DC input range of 10.5–15 V DC per cell, the TD-203192 offers exceptional versatility for diverse battery configurations.

It integrates a 64-bit digital signal processor (DSP) intelligent control chip with photoelectric isolation circuitry, delivering inverter transfer efficiency of up to 90% and AC bypass efficiency of over 99%. A built-in, automatic, three-stage AC battery charger (constant current, constant voltage and float) with an adjustable charging current ensures optimal battery maintenance for sealed, gel, flooded and lithium chemistries. The automatic transfer switch completes the transition from grid to battery in ≤4 ms, minimising disruption to critical operations.
