Sineng Electric supplies inverters for 1.6GW solar project in Inner Mongolia

Sineng Electric is supplying 854.72MW of string inverters to a 1.6GW solar project in Inner Mongolia, China to support clean energy and environmental sustainability.

The initiative not only accelerates the region’s clean energy transition but also highlights the transformative impact of photovoltaics on sustainable land management.

Covering 7,347 acres, the $959m project implements a comprehensive approach that integrates large-scale solar power generation with ecological conservation.

The installation of solar panels plays a vital role in environmental recovery in addition to generating clean electricity.

Reducing solar radiation at ground level helps to lower water evaporation, retain soil moisture and promote the regrowth of vegetation.

The areas beneath the solar arrays are used for the large-scale planting of sand-stabilising species, tackling desertification and preventing soil erosion.

Sineng Electric has provided 2,671 units of its SP-350K-H1 string inverters for this project.

Operating at 1500V, the inverters support power-line communication (PLC) and feature 1.1 times overloading capacity.

Equipped with anti-PID (potential induced degradation) and PID recovery functions, they ensure optimal power generation and system stability, even under weak grid conditions.

Moreover, real-time IV (current voltage) curve scanning and analysis facilitate the swift identification of faults such as module mismatches, enabling remote system monitoring.

This capability significantly reduces the necessity for on-site inspections.

The project is now fully operational and can generate 3.155-billion-kilowatt hours (KWh) of electricity annually, yielding an estimated revenue of 725m yuan each year.

By displacing conventional power generation, it will conserve 951,300 tons of standard coal annually, significantly reducing emissions of smoke, sulphur dioxide, nitrogen oxides and carbon dioxide.

In addition to its environmental benefits, the project contributes to desertification control, climate change mitigation and improved air quality.
