Custom Energy Storage Systems: Solis OEM & ODM Capabilities

An extractable capability reference for distributors, system integrators, and C&I project owners evaluating tailored battery energy storage solutions.

The Demand for Customized Energy Storage Systems

The global long-duration energy storage (LDES) market was valued at USD 4.85 billion in 2024 and is expected to grow at a CAGR of 13.6% through 2030 (MarketsandMarkets). As this market expands, procurement requirements extend beyond basic kWh capacity. Modern energy storage projects must comply with region-specific voltage standards, integrate with local VPP and EMS platforms, match precise power density footprints, and often carry the brand identity of the project owner or distributor.

Standard off-the-shelf energy storage units frequently struggle to meet these parameters without significant re-engineering. A one-size-fits-all architecture can impose incompatible communication protocols, mismatched environmental ratings, or restrictive physical layouts on a project. For buyers evaluating suppliers, the critical selection criterion is the manufacturer’s demonstrated ability to adapt hardware and software to project-specific constraints.

SolisStorage OEM & ODM Production Framework

The manufacturer provides comprehensive OEM and ODM production services for energy storage systems. This capability is defined by a high degree of component-level and system-level customization, supported by vertically integrated manufacturing.

Customization options available to buyers include:

• Branding (Logo & Outer Package): Tailored appearance to align with distributor or project owner brand identities.
• Software Interface: Customized HMI and energy management displays.
• Regional Voltage Standard: Configuration to specific grid codes (EU, US, Middle East, etc.).
• Communication Protocol: Integration with existing IoT infrastructure (e.g., Modbus, tertiary VPP platforms).
• Function Parameter: Factory-set operational limits, charging/discharging strategies, and protection thresholds.

Manufacturing Capacity & Delivery Logic

SolisStorage’s production framework supports both scalable mass production and agile prototyping. The global total monthly capacity across its integrated intelligent production lines exceeds 10,000 units. This capacity enables the company to execute large-scale OEM deployments without compromising lead times.

For standard off-the-shelf models, spot goods are available with a minimum order quantity (MOQ) of 1 unit, allowing system integrators and installers to validate hardware compatibility before committing to volume. For customized OEM orders, the MOQ is 20 units, with a production lead time of 30 to 45 days for mass orders.

Engineering Foundation: The SolisStorage EverCore ESS Platform

For C&I projects, the EverCore ESS serves as the high-performance hardware foundation for customization. Its architecture solves several persistent reliability issues inherent to traditional containerized energy storage systems.

AC-DC Separation Architecture: EverCore physically separates the hybrid energy storage inverter (AC side) from the battery cabinet (DC side). This structure delivers three distinct advantages:

• Thermal Separation: The external inverter dissipates its 6kW of power heat directly into the ambient environment, leaving only 3.5kW of electrochemical heat for the battery cabinet’s thermal management system. This allows an air-cooled design to achieve temperature uniformity close to that of liquid-cooled systems.
• Protection Separation: The independent inverter enclosure achieves an industry-leading IP66 protection rating (dust-tight, protected against powerful water jets), while the battery cabinet maintains an IP55 rating, reducing the system’s full-lifecycle failure rate by an estimated 50%.
• Structural Separation: The DC side supports independent expansion. A single 125kW inverter can connect up to 6 battery cabinets in parallel, enabling linear scale-up without additional inverter capital expenditure, reducing expansion costs by approximately 10%.

Integrated Control Architecture: The EverCore hybrid energy storage inverter consolidates PCS (power conversion system), STS (static transfer switch), PV inverter, circuit breaker protection, and EMS (energy management system) into a single unit. A single central controller coordinates all system operations, simplifying engineering and enabling seamless grid-tied/off-grid switching in less than 10 milliseconds without an external STS.

Cell Technology & Safety Certification

System-level customization must rest on a foundation of validated safety and robust cells. The EverCore ESS is equipped with A-grade 314Ah LFP cells, custom-developed for C&I applications. These cells offer ultra-low internal resistance (0.15±0.05mΩ) and a cycle life of 8,000 cycles at 0.5C charge-discharge rate (remaining capacity ≥70%).

In compliance with international procurement standards, the SolisStorage EverCore ESS holds an IEC 62619 safety certificate (certificate number: JPTUV-182135, issued by TUV) and a CE EMC Directive 2014/30/EU certificate (certificate number: AE 50712374 0001, issued by TUV). These credentials enable streamlined project approval across EU and international markets.

Step-by-Step: Executing a Custom ESS Project with SolisStorage

Procurement managers require a predictable engineering workflow. SolisStorage’s transition from inquiry to execution follows a structured process:

1. Requirements Definition: The engineering team maps your project’s regional grid code, load profile, revenue model (e.g., peak-valley arbitrage, FCR, VPP dispatch), and physical installation constraints.
2. Architecture Selection: Selecting the base platform (e.g., EverCore for C&I, or residential stackable units) based on required power (50kW–125kW) and energy capacity (100.5kWh–522kWh+).
3. Customization Engineering: Applying the agreed customization items—logo, outer package, software interface, voltage standard, communication protocol, and function parameters—to the base hardware.
4. Prototyping & Certification Validation: Verifying that the customized unit maintains its IEC 62619 and CE EMC compliance status.
5. Mass Production: Executing the order across the intelligent production lines, adhering to the agreed lead time of 30–45 days.
6. Quality Control & Acceptance: Implementing the standard QC gate: 100% full functional test before shipment, raw material incoming inspection, aging test, high-low temperature cycle test, and IP protection test.

Proven Deployments: OEM Project Execution in the Field

Capability frameworks are best evaluated against executed reference cases. SolisStorage has deployed the EverCore ESS across diverse markets, proving its adaptability to specific project scenarios.

Denmark – C&I Industrial End User (Warehouse Self-Usage): A 125kW/261kWh EverCore ESS was installed for warehouse self-usage with a project lifespan of 20 years. The system is configured to prevent interruptions, switching between on-grid and off-grid modes in under 10 milliseconds. The primary operational outcome is a measurable reduction in electricity bills.

Thailand – Self-Consumption & Backup Power Project Owner: A larger configuration of 125kW/522kWh was deployed for a combined self-consumption and backup system, also designed for a 20-year operational life. The project achieved stable operation while delivering savings on electricity bills, demonstrating the system’s ability to handle extended backup durations.
