Sandi Electric developed and produced the SDS series on-grid solar inverters. We were the first in China to adopt the Mitsubishi IPM intelligent module design.

We developed the SPI series solar pump inverter and were the first to apply a 110kW water pumping system in Hongqira, Kashgar, Xinjiang. At that time, it was the first successful operating case of a water pump inverter exceeding 100kW, and the equipment is still in normal operation.

We developed the SDEX series explosion-proof inverter.

We developed a 200kW high-speed rail high-power converter and passed comprehensive testing within Golden Eagle Heavy Machinery.

We developed a 500kW independent technical off-grid inverter power supply.

We collaborated with AIMS, a US-based company, and became their exclusive global power supplier. We developed a DC1000V 500A high-power charging power supply to solve the problem of high-power high-voltage charging.

We cooperated with BYD to provide cloud vehicle power and became their qualified supplier to develop and market a small-power 15kW integrated on-grid and off-grid machine.

We collaborated with Jiangsu Hydrogen Energy Company to develop military ultra-silent power supplies that meet fuel cell characteristics.

We collaborated with Sichuan Hengda Company to develop a seamless complementary hybrid energy storage system, which operated perfectly in the J-2 well of PetroChina in Inner Mongolia.

Our company had implemented the 6S and ISO9001 quality management systems, developed bidirectional high-power inverters, and created a 200kW solar inverter with static switching functionality.

Our company developed a centralized energy storage lithium battery system, utilizing advanced BMS battery management system technology to further enhance battery quality.

Our company obtained the Type Approval Certificate from the China Classification Society (CCS), signifying that our products have reached the standards of power supply in the shipbuilding industry in terms of quality and safety.
