        • Modular water fire protection: Highly efficient water fire protection system can be automatically activated on demand in extreme situations, adding extra safety protection.

          With its comprehensive safety design and certification system, the Aster 5,000 provides a reliable protection foundation for large-scale energy storage projects. Providing future technical support for the long-time energy storage market, AlphaESS said that the Aster 5000 is not only an energy storage product to meet the current market demand, but also prepares the hardware and software for the long-time energy storage market for more than 4 hours or even 8 hours discharge durations. Its self-developed BMS, active equalization and thermal management system, with flexible scalability and compatibility, will provide long-term support for future grid peaking, renewable energy distribution and energy independence.

          The Aster 5000 is now available for order, and welcomes all partners to come and make reservations. For more information, please contact us.

2. STORION Commercial & Industrial Storage Series

3.1. AlphaESS M30/M50: The Next Generation All-in-One C&I

As the demand for energy independence, streamlined operations, and greater ROI grows among commercial and industrial users, AlphaESS introduces the M30/50, an all-in-one energy storage solution engineered for performance, intelligence, and scalability.

Key Selling Points：

1. Highly Integrated, Redefining Deployment Experience

The M30/M50 focuses on a true modular design. The system is delivered pre-charged, allowing flexible transportation via truck, train, ship, or even helicopter—ready for instant deployment upon arrival.

Compared to the previous generation, no battery rack or complicated wiring is required. On-site setup is as simple as stack and start, significantly reducing installation time and labor costs.

2. Smart O&M Ensures Operational Reliability

The M30/M50 is equipped with AlphaESS’s proprietary BypassTech technology, which automatically isolates faulty modules in the event of a failure, ensuring uninterrupted system operation and minimizing business disruptions.

It also features the latest EMS 3.6 platform combined with AI algorithms to enable real-time diagnostics and SoC calibration, extending battery life and optimizing maintenance efficiency.

Moreover, the system supports both on-grid and off-grid modes, and up to 6 units can be paralleled, complying with key international standards such as IEC 62109, VDE4105, and G99, making it compatible across various European markets.

3. Designed for Profitability Optimization

The M30/M50 supports 200% DC PV oversizing, maximizing solar energy utilization and overall system ROI. With an IP66 protection rating, it is built to withstand harsh outdoor environments, making it ideal for commercial parks, hospitals, schools, and industrial facilities alike.

3. AlphaESS SMILE G3 Series: The New Generation of Flagship Residential Energy Storage

The AlphaESS SMILE G3 Series, our latest flagship residential energy storage system, integrates a cutting-edge hybrid inverter, flexible modular batteries, and intelligent energy management features. Designed specifically for European households, the SMILE G3 Series offers an efficient, reliable, and future-proof energy solution.

Key features: 

1. High Performance & Fast Return on Investment
With its powerful 1C charge/discharge rate battery, the SMILE G3 maximizes self-consumption and supports dynamic energy trading.
