(SeaPRwire) –   HEFEI, China, April 28, 2026 — Sungrow, a global leader in PV inverter and energy storage system solutions, partnered with TÜV Rheinland and the China Electrotechnical Society to launch a white paper focused on mining microgrid power solutions at the 2026 Global Renewable Energy Summit (GRES).

This white paper details Sungrow’s proprietary end-to-end mining microgrid solutions, which cover a diverse range of application scenarios: medium-scale systems (2.5MW–20MW), large-scale projects (20MW–100MW), and multi-microgrid clusters exceeding 100MW. Tailored products and technologies are provided to support each specific use case.

Sungrow’s mining microgrid power solutions are built on a fully in-house developed, tightly integrated system architecture that spans PV, wind, energy storage, charging, and integrated energy management systems. This enables seamless coordination across all assets and system-level control strategies. The solution offers full-lifecycle closed-loop optimization, as well as an industry-first five-layer protection framework to ensure stable, resilient system operation.

Delivering Measurable Full-Lifecycle Value

• Lower upfront costs with one-stop system design: PV, energy storage, and backup power systems are sized based on on-site conditions and load profiles, using an intelligent design platform and validated via gigawatt-scale simulations.
• Simplified Deployment: Pre-integrated assets with standardized parameters and communication protocols enable faster installation and streamlined commissioning, with seamless third-party integration.
• Up to 12% higher economic returns through intelligent dispatch: The system evaluates thousands of operating scenarios in real time to optimize performance, with fully visualized and traceable performance and carbon data to support quicker decision-making and ESG reporting.
• Smarter and more reliable O&M: Predictive maintenance and IV-based diagnostics detect over 20 module-level issues, with cell-level risks identified up to seven days in advance, supported by a global 24/7 service network.

Five-Layer Protection for Resilient Microgrid Operation

To ensure ultra-high system stability, the solution introduces a five-layer protection framework that categorizes grid conditions from steady-state operation to full grid collapse. Each stage is managed via dedicated control strategies to maintain stable performance. The system enables rapid fault isolation in response to disruptions, ensuring uninterrupted power supply through capabilities including PV generation and load forecasting, fault ride-through, seamless grid-tied and off-grid switching, and black start.

Proven Performance in Global Mining Projects

“Zambia is currently facing a power deficit of 600–750 MW amid drought and rising energy demand, with the mining sector consuming roughly 50% of the country’s total electricity, and national total demand projected to exceed 11,000 MW by 2050,” said Chilala Kakoma Bowa, Executive Director and Senior Consultant at the Zambia Renewable Association.

To help address these challenges, Sungrow has deployed a 1.38MW/2.26MWh mining microgrid system at the Naipu mine in Zambia. This project effectively mitigates severe power shortages caused by 8–12 hours of daily outages, delivers approximately 1.9 million kWh of renewable energy each year, and significantly improves operational stability. Additionally, Sungrow’s mining microgrid solutions have been widely adopted across global mining projects. A prominent example is the 12MW/13MWh HyIron Oshivela project in Namibia, which operates fully off-grid and generates around 36 million kWh of clean electricity annually, meeting 100% of the site’s energy demand.

“As mining operations face growing demands for energy security and decarbonization, the industry’s focus is shifting from fragmented systems to fully integrated, end-to-end microgrid solutions that can ensure consistent performance under complex conditions,” said Rui Sun, General Manager of the Grid Technology Center at Sungrow. “With this white paper, we aim to provide a systematic approach to mining microgrid design and operation, helping the industry address rising system complexity while accelerating the transition to cleaner, more reliable energy.”
