In March 2026, four departments including the Ministry of Industry and Information Technology and the National Development and Reform Commission jointly issued the "Implementation Plan for the High-Quality Development of Energy-Saving Equipment (2026-2028)." The document proposes that by 2028, the p...... READ MORE

In the past, when selecting a current sensor, engineers typically focused on three parameters:measurement range, accuracy, and whether the package would fit.If these criteria were met, the sensor would generally make the shortlist.However, this approach is no longer sufficient.Current levels in ener......

In the past, in many power electronic equipment, the main tasks of current, voltage, and residual current detection were:Anomalies are found. If the current is too large, protection is required; if the voltage is abnormal, an alarm is required, if leakage occurs, it needs to be cut off. Sensors are...... READ MORE

On July 28, the U.S. Federal Communications Commission (FCC) officially added foreign-produced power inverters to its "Covered List." Many media outlets immediately focused on two questions:Is this a new trade restriction? Will Chinese inverter exports be affected?Capital markets also reacted s...... READ MORE

As high-capacity battery cells and 5MWh-class energy storage systems increasingly become the market mainstream, energy storage systems are placing higher demands on thermal management capabilities. Compared to traditional air-cooling solutions, liquid cooling enables more uniform battery temper......

As China’s offshore wind power sector rapidly enters the era of ultra-large-capacity turbines, 18–20 MW units are moving into the grid-connection pilot phase for deep-sea applications, and 25 MW grid-forming converters have already rolled off the production line for testing. Larger turbine capacity...... READ MORE

In January 2026, the National Development and Reform Commission and the National Energy Administration jointly issued the *Notice on Improving the Capacity Price Mechanism for Power Generation ( [2026] No. 114). This document marked the first time a national-level policy explicitly called for establ...... READ MORE

Many energy storage projects encounter a common issue during the commissioning phase:The battery voltage appears normal and the BMS reports no faults, yet the SOC (State of Charge) reading becomes increasingly unreliable.It displays 100% immediately after a full charge, but after a period of operati......

IntroductionDriven by the "dual carbon" strategy, energy storage systems have become an essential component of modern power systems, they serve as both a "buffer" for integrating renewable energy and a "stabilizer" for grid peak shaving and frequency regulation. From grid-side energy storage station...... READ MORE

For a long time, the management of substation batteries was essentially a "periodic task."It involved measuring internal resistance once a year, conducting periodic capacity verification discharges, checking that float-charge voltages were within normal ranges, and recording the data in a log. For m...... READ MORE

—Rethinking Current Sensing Systems in the MLPE EraForeword: What is becoming increasingly difficult is not the inverter itself, but the "sampling."In recent years, micro-inverters have been regarded as the quintessential MLPE (Module-Level Power Electronics) solution for residential photovoltaic sy......
