C&I Energy StorageCertification

As commercial and industrial (C&I) energy storage projects scale up, procurement teams face a critical challenge: how to verify that a supplier’s system meets stringent safety and performance certification requirements while delivering reliable long-duration operation. In the European market, compliance with IEC 62619 (safety) and CE EMC Directive 2014/30/EU is non-negotiable for grid connection and insurance underwriting. Yet many systems still fall short of these standards, exposing buyers to project delays, penalties, and safety risks.

SolisStorage, the energy storage subsidiary of Solis (Ginlong Technologies, Shenzhen Stock Exchange: 300763), has introduced the EverCore ESS — a long-duration C&I energy storage system designed from the ground up for certification compliance, architectural simplicity, and low total cost of ownership. With more than 20 years of power electronics expertise and a global footprint across 100+ countries, SolisStorage positions the EverCore as a turnkey solution for buyers who demand verifiable safety credentials and bankable long-term performance.

Certified Safety & Compliance – A Direct Answer to Procurement Concerns

The EverCore ESS (models including EverCore-261kWh and EverCore-261kWh-PRO) holds IEC 62619 certification (TUV certificate JPTUV-182135) and CE EMC Directive 2014/30/EU certification (TUV certificate AE 50712374 0001), covering electromagnetic compatibility standards EN IEC 61000-6-2:2019, IEC 61000-6-2:2016, EN IEC 61000-6-4:2019, and IEC 61000-6-4:2018. These certifications are valid for the EU market and issued by TUV, a globally recognized testing authority.

Long-Duration Architecture That Reduces Lifecycle Costs

The EverCore ESS is a C&I energy storage system built with LFP (lithium iron phosphate) cells – EVE 3.2V/314Ah cells offering a cycle life of 8,000 cycles at 70% end-of-life. This enables a system lifespan of 15–16 years under typical daily cycling, meeting the definition of long-duration storage for commercial applications.

• Power & Energy Ratings: Available in 50kW/100.5kWh, 60kW/120.6kWh, and 125kW/261.2kWh configurations.
• Protection: IP55 cabinet (battery side) + IP66 inverter (AC side), with C4 anti-corrosion coating for harsh environments.
• Operating range: -25°C to 55°C, up to 4,000m altitude – suitable for climates from Middle Eastern deserts to Nordic winters.
• AC-DC separation architecture physically decouples the inverter and battery, improving thermal management and reducing failure rates by 50% over traditional integrated designs.

Real-World Deployment: Denmark & Thailand Case Studies

To verify real-world reliability, the EverCore ESS has been deployed in multiple sites across Europe and Asia. Two representative projects illustrate its suitability for long-duration storage:

Denmark – 125kW/261kWh Warehouse Self-Usage

A Danish warehouse operator installed a single EverCore 125kW/261kWh system to optimize self-consumption of rooftop solar. The system switches between on-grid and off-grid in less than 10 milliseconds, ensuring no interruption to sensitive logistics operations. Projected lifespan: 20 years. The client reports significant electricity bill savings and zero compliance issues during local grid inspections.

Thailand – 125kW/522kWh Self-Use & Backup

In Thailand, a 125kW EverCore unit paired with a second battery cabinet (total 522kWh) provides backup power for a manufacturing facility. The system operates in both grid-tied and off-grid modes, with seamless switching. The 8000-cycle LFP cells guarantee long-duration backup capability without frequent replacement.

Both cases demonstrate that EverCore meets the IEC 62619 and CE EMC compliance required for grid interconnection in Europe and similarly regulated markets, giving procurement teams confidence in supplier credentials.

Open Ecosystem for Advanced Energy Trading

Beyond compliance, the EverCore ESS features an open software ecosystem: it is already connected to 102 third-party VPP/EMS operators across 11 European countries, including the Kraken platform (Octopus Energy) in the UK and Check Watt in the Nordics. This allows owners to participate in ancillary services (FCR/aFRR/mFRR), demand response, and virtual power plant (VPP) programs – turning long-duration storage into a multi-revenue asset.

For buyers, this means the system is not only certified for safety but also future-proofed for evolving electricity markets. The Solis AI Cloud Platform, deployed at over 5,500 storage stations globally, provides minute-level dynamic optimization of charge-discharge strategies based on wholesale and retail price forecasts.

Market Trend & Why Certification Matters Now

According to industry data, the global C&I energy storage market is expected to grow at a CAGR of over 25% through 2030, with Europe leading the adoption of long-duration systems (>4 hours). Regulatory frameworks like the EU Battery Regulation (2023/1542) and national grid codes increasingly require certified safety and EMC compliance. Suppliers that cannot provide verifiable certifications face growing market barriers.

SolisStorage’s investment in IEC and CE certification for the EverCore series positions it as a reliable partner for procurement teams who need to minimize technical risk and accelerate project approval. With an MOQ as low as 1 unit (standard models) and 20 units for customized OEM orders, the barrier to trial is low.

Future Outlook

As long-duration energy storage becomes central to decarbonizing industry, the ability to prove compliance at every level — from cell (314Ah, 8000 cycles) to system (IP55/IP66, CE EMC) — will differentiate serious suppliers from commoditized alternatives. SolisStorage continues to invest in R&D, with a 1,000+ person engineering team and a global service network that includes 27 overseas centers and 48-hour on-site fault response.

For buyers evaluating C&I energy storage suppliers, the EverCore ESS presents a clear value proposition: certified safety, proven long-duration performance, architectural innovation, and an open software ecosystem that reduces both capital expenditure and operational risk.
