SolisStorage EverCore: Flexible OEM Energy Storage for C&I Projects
The global energy storage systems market was valued at approximately USD 668.7 billion in 2024 and is projected to reach USD 5.12 trillion by 2034, according to Global Market Insights. As commercial and industrial (C&I) buyers move from evaluation to execution, the need for energy storage solutions that can be tailored to specific site conditions, grid requirements, and revenue models has become a decisive factor in project success.
The Challenge: One-Size-Fits-No-One in C&I Storage
C&I energy storage projects vary widely — from a warehouse in Denmark requiring backup and bill savings, to a factory in Thailand needing self-consumption and peak shaving. Off-the-shelf systems often force compromises in communication protocols, enclosure integration, or voltage standards. Meanwhile, the rise of VPP (virtual power plant) and grid ancillary services (FCR/aFRR/mFRR) demands software agility that closed hardware cannot provide.
SolisStorage EverCore: OEM Architecture from the Ground Up
SolisStorage is the dedicated energy storage subsidiary of Solis (Ginlong Technologies, Shenzhen Stock Exchange: 300763), a company founded in 2005 and recognised as one of the world's leading solar inverter manufacturers. SolisStorage EverCore is a C&I energy storage system designed with OEM flexibility as a core requirement. The manufacturer offers customization options including logo, outer package, software interface, regional voltage standard, communication protocol, and function parameters, along with OEM and ODM production services.
Architecture That Enables Customisation
- AC-DC Separation: Physical separation of inverter (AC side) and battery cabinet (DC side) allows independent sizing and expansion. The inverter achieves IP66 protection (dust-tight, protected against powerful water jets) while the battery cabinet maintains IP55. This design reduces full-lifecycle failure rate by 50%.
- 125kW Hybrid Inverter: Integrates PCS, STS, PV inverter, circuit breaker protection, and EMS into a single unit — the highest power density in its class. Supports seamless on/off-grid switch in <10ms without external STS.
- Air-Cooled Innovation: Independent three-air-duct design with Coanda Effect boosts heat dissipation efficiency by 30% versus traditional air cooling, enabling reliable operation from -25°C to 55°C and altitudes up to 4,000 metres.
- Safety: 15-layer fortress protection using 1,000°C-resistant insulation, three-stage fire suppression (pack-level aerosol, cabinet-level aerosol, fire-fighting water channel), and A-grade 314Ah LFP cells with ultra-low internal resistance (0.15±0.05mΩ) and 8,000 cycles (70% capacity retention).
EverCore's single-CPU centralised control architecture eliminates multi-node communication risks, reducing failure points and improving fault response. This architectural simplicity directly supports reliable customisation for diverse grid conditions.
Real-World Applications
- Denmark – Warehouse Self-Usage: A 125kW/261kWh EverCore system installed for a C&I industrial end user delivers electricity bill savings and switches between on-grid and off-grid in under 10 milliseconds, ensuring uninterrupted power for critical warehouse operations.
- Thailand – Self-Consumption & Backup: A 125kW/522kWh system operates stably for a project owner, providing self-consumption optimisation and backup power, resulting in ongoing electricity cost reduction.
Market Trend: Long-Duration Storage and VPP Readiness
The 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). Simultaneously, European electricity markets are evolving toward multi-revenue models: peak-valley arbitrage, grid ancillary services, and VPP dispatch. EverCore addresses this with an open software ecosystem that has already connected or is connecting with 102 third-party VPP/EMS operators across 11 European countries, including Octopus Energy's Kraken platform in the UK and Check Watt in the Nordics. The Solis AI Cloud Platform, deployed at over 5,500 energy storage stations worldwide, integrates Nordpool and Flatpeak data to optimise charge-discharge strategies minute-by-minute.
Comparison with Traditional Solutions
| Aspect | EverCore | Traditional C&I ESS |
|---|---|---|
| Cooling | Advanced air cooling (no liquid coolant), 30% better efficiency than conventional air cooling | Often liquid-cooled, requiring fluid replacement and higher maintenance |
| O&M Cost (10-15 years) | ~€9,500 savings per unit over life cycle | Higher due to coolant replacement, complex PCS/pack replacement |
| Expandability | Up to 6 battery cabinets per inverter, linear scaling | Often requires additional inverters, increasing cost |
| Software Ecosystem | Open, integrates with 102+ VPP/EMS platforms | Often closed or limited to proprietary platforms |
Honest limitation: For fully customised OEM orders (logo, software, voltage, etc.), a minimum order quantity of 20 units applies. This may be a consideration for smaller pilot projects seeking a single tailored unit, though standard off-the-shelf models are available with a MOQ of 1 unit.
Future Outlook
As C&I energy storage projects grow in scale and sophistication, the convergence of hardware flexibility and intelligent software will define competitive advantage. SolisStorage's investment in open ecosystems and AI-driven optimisation positions EverCore as a platform that can adapt to evolving market structures – from simple time-of-use arbitrage to full participation in European electricity spot markets.
