Different Storage Applications, Different System Architectures

Key takeaways:

• Hoenergy showcased 4 BESS platforms designed for commercial, industrial and utility-scale applications

• The portfolio includes hybrid, all-in-one and modular storage architectures with different integration and expansion strategies

• According to the company, system design is increasingly influenced by application requirements, scalability and future expansion needs

Energy storage is expanding across residential, commercial, and utility-scale applications. A single system architecture may not be suitable for every deployment scenario. A storage system designed for peak shaving and backup power at a C&I installation may have different requirements than the one deployed for solar-plus-storage plant or a grid-support installation.

At the SNEC 2026 in Shanghai, Hoenergy showcased a range of battery energy storage systems (BESS) solutions targeting different market segments. Speaking to TaiyangNews, Ray Jiang, Sales Manager highlighted 4 products designed specifically for the overseas markets, each based on a different system architecture.

A hybrid storage platform, D-Cube H series integrates battery storage with solar generation. The system utilizes hybrid inverters, allowing direct integration with PV systems and supporting self-consumption and backup power applications.

For C&I applications, the company presented D-Cube S125/261 EU, an all-in-one liquid-cooled ESS developed for European market. Ray emphasized that over 5,000 units of the S-series have already been deployed, making it one of the most established storage platforms.

The D-Cube A series uses a different design in which the PCS and battery cabinets are physically separated. This enables an addition of battery cabinets for extended storage duration without modifying the PCS infrastructure. While integrated systems simplify installation and commissioning, modular systems provide flexibility where the importance of future expansion is anticipated.

For larger solar-plus-storage projects, Hoenergy offers D-Cube F series, with an 800 V battery storage platform designed for high-voltage applications. According to Ray, the system can be integrated with PV inverters and connected through a step-up transformer for utility-scale projects.

Across the product portfolio, Hoenergy highlights features such as liquid cooling, integrated battery management systems (BMS), and modular configurations designed for different storage applications.
