Vertically integrated PV manufacturer LONGi, which has entered the energy storage sector recently, has signed an energy storage cooperation agreement with Shanxi Dingxin Logistics. Under the agreement, it will supply a LONGiBank liquid-cooled energy storage system (ESS) for the logistics company’s heavy-truck charging station in Yuncheng, Shanxi province. LONGi describes the facility as the largest heavy-truck charging station in Shanxi, with daily electricity consumption of around 150,000 kWh.
A 3.2 MW rooftop distributed PV system at the site was connected to the grid at the end of 2025, using LONGi Hi-MO X10 modules and providing estimated average annual generation of approximately 4 million kWh. With the addition of the storage system and LONGi One OS energy management system, the site will integrate PV generation, energy storage and heavy-truck charging under a unified dispatch system. The storage system will absorb surplus midday solar generation, support time-of-use electricity price arbitrage and reduce grid impacts from high-power heavy-truck charging.
Huawei Digital Power’s SUN2000-506KTL-H1 smart string inverter has obtained certification under Germany’s VDE-AR-N 4110, 4120 and 4130 grid-connection standards, covering medium-, high- and extra-high-voltage networks, respectively. Huawei said it is the world’s first 500 kW-class smart string inverter to obtain all three certifications.
The inverter has a maximum efficiency of 99.1% and European efficiency of 98.8%. Its grid-forming capabilities include active transient overvoltage suppression, inertia response and wideband oscillation damping. The inverter series has also received a Grid-Forming Unit Certificate from TÜV SÜD based on the VDE FNN Guideline Version 2.1:2026, supporting grid stability in systems with high renewable penetration and weak-grid conditions.
Midea New Energy, the renewable energy business of Chinese appliance manufacturer Midea Group, has launched a 5.5 MW centralized aggregation PV demonstration project in Donglu Village, Zhangzhuang Township, Pei County, Xuzhou, Jiangsu province.
According to the company, the project uses a clustered residential rooftop PV development model, installing distributed PV systems on local households’ roofs and aggregating their output for centralized grid connection.
China’s Ministry of Industry and Information Technology, National Development and Reform Commission and National Energy Administration, together with two other government departments, have launched applications for the 2026 national green computing facility program. The program will select facilities with high energy and carbon efficiency, low-carbon operations, appropriate siting, advanced technologies and sound management.
It covers computing facilities in sectors including industry, information and communications, energy, the internet, finance and public institutions. The share of electricity consumption supplied by wind, solar and other renewable energy sources must be no lower than the renewable electricity consumption responsibility weighting applicable to the province, autonomous region or municipality where the facility is located.
The authorities will also encourage new computing facilities to be planned and deployed in coordination with renewable power generation, provided they have stable supporting power supplies and flexible regulation capabilities, with the aim of improving the alignment between electricity demand and renewable generation.
