Sungrow launches 3.5 MW ultra-fast charging system
Chinese inverter and energy storage giant, Sungrow, has launched the ChargeStack1000, a 3.5 MW ultra-fast charging system, which it claims to be the world’s first of its kind compliant with the European standards. The ChargeStack1000 features a scalable“1+X” architecture, enabling seamless expansion from 1 MW to 3.5 MW. The system achieves 97% efficiency and 98.5% availability, with throughput improved by 33%. Through integration with PV and energy storage, customers can realize up to 60% additional revenue. The system also supports plug-and-charge, the OCPP 2.0.1 protocol, and can be deployed within 2–4 weeks.
Meanwhile, in September this year, Sungrow partnered with Dublin-based solar installer Solar Clarity Ltd to deliver a solar energy system for Meadowvale Tennis Club, helping the club reduce electricity costs and support its mission of affordable, community-focused sport (see Dublin Tennis Club Serves Up Sustainable and Affordable Sport with Solar Installation by Sungrow)

Sichuan issues mechanism renewable electricity plan
The Sichuan Energy Bureau has issued an implementation plan for the market-based reform of renewable electricity pricing, aiming to ensure full market participation of wind and solar power by the end of 2025.
Under the plan, existing projects (commissioned before June 1, 2025) will receive guaranteed “mechanism electricity” priced at RMB 0.4012/kWh ($0.056/kWh), equivalent to the benchmark coal price, with annual guaranteed operating hours of 400 for wind and 300 for solar. New projects (commissioned on or after June 1, 2025) will determine their mechanism electricity and price through competitive bidding, with a bidding range of RMB 0.2–0.4012/kWh ($0.028–0.056/kWh). The mechanism will remain valid for 12 years.
