July 25, Zhiguang officially launched its third-generation cascaded high-voltage large-capacity energy storage system — ZGEner-Plus 3.0 — at the Energy Storage Engineering Conference in Chengdu. As a flagship product, it directly addresses key challenges in large-scale energy storage with four core value propositions: simplified station design, superior grid support, ultimate safety, and high efficiency, offering investors and operators intelligent solutions that cover the entire lifecycle and all application scenarios.

Core Value Highlights

1. Significantly Increased Unit Scale, Lower Cost and Higher Efficiency

Up to 100MW/200MWh per unit: Reduces the number of devices needed, simplifies system architecture, lowers initial capital expenditure (CAPEX), and saves 20% in land use.

Equipped with high-performance 587Ah large-capacity cells: Achieves >94.5% standard round-trip efficiency and 20% higher energy density.

Direct connection to 35kV grid with ≥92% conversion efficiency: Maximizes operational income (OPEX) for power stations.

Faster deployment, earlier returns: Simplified engineering design shortens installation and commissioning time by 25%, enabling quicker grid connection and faster ROI.

2. Outstanding Grid-Forming Capability, Ensuring Grid Safety and Stable Returns

Strong grid adaptability and support: Operates reliably under harsh conditions like isolated, micro, or weak grids (e.g., SCR < 2, R/X > 0.5), effectively managing fluctuations from renewable energy inputs.

Integrated key grid functions: Features one-click black start, millisecond-level power support at the 100MW scale, and stable island-mode operation with load. This ensures a resilient smart grid and enables participation in source-grid-load-storage coordination, boosting the plant’s value in the ancillary services market.

3. Safety and Reliability as the Foundation, Safeguarding Asset Value

Modular high-voltage topology: Eliminates circulating current risks, ensuring structural reliability.

Extreme environmental adaptability: IP55 protection, operates in -40°C to 45°C, supports high-altitude deployments for global application scenarios.

Comprehensive intelligent monitoring and early warning: Real-time monitoring of battery temperature differentials, voltage deviations, consistency, and lifespan — enabling accurate current control and proactive risk prevention throughout the station’s lifecycle.

4. Intelligent Operation Empowerment, Maximizing Lifecycle Value

Zhiguang’s proprietary 5S intelligent platform (PCS/BMS/EMS/CMS/DMS): Enables full-lifecycle intelligent management from R&D to delivery, operation, and trading.

Cloud-edge synergy and 3D digital twin: Supports full-scenario online monitoring, smart scheduling, and remote O&M, making station operations more efficient and trading decisions more precise.

Market insights: Offers multidimensional data analysis for electricity spot and frequency regulation markets, helping operators make better decisions.

Equipped with the BMS 3.0 High-Reliability & Scalable Platform

High-reliability architecture: Full-temperature range active protection with precise SOC accuracy across wide temperature ranges.

Scalability: Seamless protocol compatibility, native support for IEC61850 and Modbus TCP/RTU, direct connection to energy management platforms without a gateway. Dynamic cluster expansion supported for flexible deployment.

AI Trend Insight Engine: Simulates battery cluster degradation trends using historical data, dynamically adjusts strategies to extend asset life.

Fully remote software maintenance: Supports online upgrades for master/slave controllers, BAMS, and IEC61850 protocol stacks, with rollback protection to avoid bricking, significantly reducing O&M cost and difficulty.

Smart O&M knowledge base: Real-time root cause analysis with immediate response suggestions, enhancing operational efficiency.

This product launch brought together leading experts and key clients in the energy storage field to witness the global debut of ZGEner-Plus 3.0. Based on 12 years of deep expertise in cascaded high-voltage storage systems and comprehensive strengths in manufacturing, testing, R&D, and big data analytics, ZGEner-Plus 3.0 marks a breakthrough in addressing the core needs of large-scale storage projects — economic viability, safety, grid adaptability, and intelligent O&M — delivering robust technical and value support for the global energy storage industry’s high-quality development.
