An E-House (Electrical House / Prefabricated Substation) is a factory-built, modular electrical room that integrates medium/low voltage switchgear, transformers, variable frequency drives, control systems, power quality equipment, and auxiliary systems into a standardized container or steel structure. It is fully assembled, wired, and pre-commissioned at the factory, then transported to site for rapid deployment. Read More

On April 16, 2026, China's National Energy Administration (NEA) and National Development and Reform Commission (NDRC) jointly issued a mandatory action plan requiring the complete resolution of voltage sag issues — commonly known as "flickering" or "momentary power interruptions" — by the end of 2028. The announcement gives the industry a clear three-year deadline to implement comprehensive solutions. Read More

The "Intelligent Heart" and "Scavenger" of PV Plants: An Application Analysis of High-Voltage SVG and Passive Filtering EquipmentWith the acceleration of the global energy transition, photovoltaic (PV) power plants, as a mainstay of clean energy, are rapidly developing towards largWith the acceleration of the global energy transition, photovoltaic (PV) power plants, as a mainstay of clean energy, are rapidly developing towards large-scale and clustered configurations. However, integrating unstable solar power into the grid efficiently and with high quality presents a complex technical challenge. Among these, the reactive power compensation and harmonic mitigation are two core issues ensuring the safe, compliant, and efficient operation of a plant. This article delves into the application of key equipment addressing these issues—High-Voltage SVG (Static Var Generator) and Passive Filtering Equipment—in PV systems. Read More

How to Select the Right Filter for a Variable Frequency Drive (VFD)?A Case Study on the ABB ACS880-07-0880A-3 VFD and 435kW High-Speed Motor System In industrial drive systems, the VFD itself is a significant source of harmonics. Selecting the correct filter for it is not only related to the operati Read More

SKD (Semi-Knocked Down) is a semi-disassembled production model where battery packs are delivered as standardized modules and components for local assembly, rather than as fully finished products. This solution is specifically designed for overseas customers who want to establish local battery assembly capabilities, reduce import tariffs, and respond to local market demands quickly. With our SKD solution, you can transform from a "trader" to a "local manufacturer" with minimal investment, leveraging the growing demand for energy storage in emerging markets. Read More

The modern power grid is a complex and vital infrastructure, essential for the functioning of virtually every aspect of contemporary life. However, with the increasing use of non-linear load equipment such as variable frequency drives, LED lighting, and computer power supplies, harmonic distortion h Read More
