A stackable ESS (Energy Storage System) solution refers to modular battery systems that can be combined or 'stacked'to increase energy capacity and power output according to project needs. Unlike traditional fixed-capacity storage units, stackable ESS allows users to expand storage gradually and tailor system size for residential, commercial, or utility applications.

The modularity of stackable ESS systems provides several advantages: flexibility in deployment, easier maintenance, and reduced upfront investment. These systems often include intelligent battery management systems (BMS), real-time monitoring, and standardized components, making scaling simple and cost-effective.

Types of Stackable ESS Solutions

• Residential Stackable ESS: Typically in 5–10 kWh modules, wall-mounted or rack-mounted, allowing homeowners to expand capacity as needed. Examples include Dagong ESS 5kWh–80kWh stackable home storage systems.

• Commercial & Industrial Stackable ESS: Larger modular systems such as 100–372kWh rack-mounted or liquid-cooled cabinets, designed for offices, retail, and light industrial loads. Modules can be paralleled to achieve the required capacity.

• Containerized Stackable ESS: For utility-scale or microgrid applications, containers with 1MWh–5MWh capacity can be stacked or combined, such as Dagong ESS 3.35MWh liquid-cooled or 5MWh air-cooled ESS containers.

Features of Stackable ESS Solutions

• Modular Design: Add or remove modules easily to match energy requirements.

• Flexible Deployment: Suitable for rooftop, rack, or container installations.

• Scalability: Capacity can grow with energy demand.

• Enhanced Safety: Integrated BMS and thermal management prevent overcharge, over-discharge, and overheating.

• Cost Efficiency: Reduces upfront investment and allows incremental expansion.

Applications of Stackable ESS Solutions

• Residential Energy Storage: Homeowners can start with small modules (5–10 kWh) and expand to 30–80 kWh as solar PV systems grow or electricity storage needs increase.

• Commercial & Industrial Storage: Offices, shops, or factories can combine modules to meet daily peak shaving, load shifting, or backup power requirements.

• Utility-Scale & Microgrids: Stackable containerized solutions provide flexibility in microgrid projects, renewable integration, and energy trading.

Price of Stackable ESS Solutions

The cost of stackable ESS systems depends on system capacity, module type, control software, installation conditions, and auxiliary equipment. Pricing is usually quoted under international trade terms such as EXW, FOB, or CIF, depending on project location and logistics preferences.

For a tailored quotation based on specific project needs, it is recommended to consult directly with the supplier.

How to Select a Stackable ESS Solution for Your Project?

• Capacity Planning: Estimate current and future energy storage needs.

• Deployment Type: Decide between wall-mounted, rack-mounted, or containerized solutions.

• Battery Chemistry: Consider LFP or next-generation chemistries depending on safety, lifespan, and performance requirements.

• Scalability & Maintenance: Choose modular systems with easy maintenance and expandability.

How Long Does a Stackable ESS Last?

• Residential LFP modules typically last 10–15 years with 6000–8000 cycles.

• Commercial and containerized systems may achieve similar lifespans depending on thermal management and operational conditions.
