Enhancing Efficiency, Safety, and Flexibility in Renewable Energy Projects
Shenzhen, China – Hopewind, a global solution provider in renewable energy, has strengthened its innovation pipeline, with its next-generation Liquid-Cooled Centralized Photovoltaic Inverter and Energy Storage PCS Integrated System, setting a new benchmark for utility-scale solar and battery projects. Built on an intelligent 2MW+ liquid-cooling platform, the solution—already securing orders worldwide—delivers unparalleled power density, safety, and adaptability for high-temperature regions.
Unified High-Power Architecture
The system provides either PV inverters (HPHV series: 2.2–8.8MW) or battery storage (HopePCSHV series: 2.5–10MW) on an intelligent liquid-cooling platform, supporting turnkey stations up to 8.8MW for solar farms and 10MW for BESS installations. It also enables seamless AC-coupled PV+BESS hybrid operation functioning as an off-grid microgrid during outages.
Intelligent Thermal Mastery
At its core, Hopewind’s proprietary tri-zone cooling technology deploys phase-change cooling for capacitors, liquid cooling for IGBT modules, and air-to-air heat exchangers for auxiliary components. Enhanced by AI-driven temperature control logic, this system achieves zero derating at 51°C ambient temperatures and sustains 1.1x overload capacity at 45°C—critical for maximizing yield in extreme climates. The design concurrently reduces operational noise and energy consumption while extending component lifespan.
Grid-Forming Solution
The platform sets new safety benchmarks with IP66-rated isolation cabinets, ensuring reliability in dusty, humid, or corrosive environments. Multi-layer protection includes terminal temperature monitoring to detect abnormal temperature led by virtual connection and millisecond-response smart fuses that eliminate overcurrent fire risks. Hopewind is a proven innovator in Grid-Forming technology with projects deployed in wind power, PV and BESS. The platform supports VSG based Grid-Forming technology, delivering inertial response, voltage support, black-start capability, and robust performance in weak-grid areas.
Operational and Cost Efficiency
Engineered for rapid deployment and minimal upkeep, the solution features modular components including remarkably lightweight 10 kg IGBT modules replaceable onsite in minutes—alongside maintenance-free liquid cooling units and self-cleaning external fans. Real-time monitoring and diagnostics of coolant levels, temperatures, and system faults ensure intelligent maintenance and operation.
Deployment Flexibility
Prefabricated 20ft/40ft containerized stations pre-tested with integrated inverters, transformers, and PCS cut installation time. For solar applications, an ultra-wide 875–1500V MPPT voltage range ensures full-load operation across periodic temperature fluctuations, while BESS projects benefit from industry-leading power density to minimize land use.
This platform redefines viability for large-scale renewables. By merging ultra-high power density with grid-forming technologies and AI-driven thermal management, it provides a reliable, cost-efficient solution even in harsh environments.
