Selecting an energy storage system (ESS) partner is a strategic decision that affects your operations, energy costs, and environmental goals for a decade or more. SolisStorage, the energy storage subsidiary of Solis (Ginlong Technologies) (Stock Code: 300763.SZ), combines over two decades of power electronics expertise with a global service network to deliver reliable, long-term solutions for commercial and industrial (C&I) users. This article explains why the SolisStorage EverCore ESS is engineered for lifecycle value, operational simplicity, and future-proof compatibility.
Problem Definition: Why Long-Term Partnership Matters in Energy Storage
C&I energy storage projects typically have an asset lifecycle of 10 to 15 years. Owners often compare initial capital expenditure (CAPEX) carefully but underestimate how operating and maintenance costs (OPEX), system evolution, and supplier reliability impact project IRR. Choosing a partner with proven technology, global support, and an open ecosystem ensures that your investment remains profitable and adaptable as energy markets evolve.
Industry Background: The Rapid Growth of the Energy Storage Market
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. The C&I segment is a key growth driver as businesses seek to reduce energy costs, improve resilience, and participate in grid services. Solis, a top-three global inverter manufacturer (Wood Mackenzie, 2023), brings its extensive experience to the storage market through SolisStorage, with products deployed in more than 100 countries.
Detailed Solution: SolisStorage EverCore ESS
The EverCore ESS is a C&I energy storage system designed for reliability, simplicity, and total cost of ownership. It uses an AC-DC separation architecture that physically decouples the hybrid inverter (AC side) from the battery cabinet (DC side), delivering three key advantages:
- Thermal separation: Only 3.5 kW of electrochemical heat needs to be managed inside the battery cabinet (versus 6 kW in traditional designs), enabling air cooling with temperature uniformity close to liquid-cooled systems.
- Protection separation: The inverter achieves IP66 (dust-tight, powerful water jets), while the battery cabinet maintains IP55, reducing the system’s full-lifecycle failure rate by 50% based on Solis’s 20 years of power electronics experience.
- Structural separation: One inverter can connect up to six battery cabinets in parallel, allowing linear capacity expansion without additional inverter investment—reducing expansion costs by approximately 10%.
The 50–125 kW hybrid energy storage inverter integrates PCS, STS, PV inverter, circuit breaker, and EMS into a single unit. With a single-unit power rating of 125 kW, it has the highest power density in its class. Key practical benefits include grid-tied/off-grid switching in less than 10 ms (no external STS required), support for DC and AC coupling with PV over-sizing up to 200%, and direct grid connection for up to six units in parallel without an external grid cabinet.
EverCore retains an air-cooled design using an independent three-air-duct system with Coanda Effect technology, boosting heat dissipation efficiency by 30% compared to traditional air cooling. It operates in temperatures from -25°C to 55°C and at altitudes up to 4,000 meters.

Ultra-Simplified O&M Platform
Over a full project lifecycle, EverCore saves approximately €9,500 per unit in O&M costs by eliminating liquid cooling fluid replacement, simplifying PCS and pack replacement, and reducing routine inspection complexity. Components such as Minebea cooling fans (10-year maintenance-free, MTBF above industry average) and Honeywell industrial-grade flammable gas detectors (10-year calibration-free) further reduce lifecycle costs.
Safety Protection and Battery Cells
EverCore features a 15-layer, three-dimensional protection system spanning cell, pack, and system levels. Thermal insulation materials resistant to 1,000°C are used between packs, and a three-stage progressive fire-fighting mechanism (pack-level aerosol, cabinet-level aerosol, fire-fighting water channels) is implemented. The system uses A-grade 314 Ah LFP cells (EVE) with ultra-low internal resistance (0.15±0.05 mΩ) and 8,000 cycles at 0.5C (≥70% capacity retention), extending the system’s economic life to approximately 16 years.

Open Software Ecosystem
Leveraging operation experience from over 300,000 energy storage sites worldwide, Solis has connected EverCore to 102 third-party VPP/EMS operators across 11 European countries, including the Kraen platform (Octopus Energy in the UK) and Check Watt (Nordic). The Solis AI Cloud Platform, deployed at more than 5,500 storage power stations, integrates Nordpool and Flatpeak data for minute-level dynamic optimization of charge-discharge strategies. In a residential project in Latvia, AI optimization increased annual electricity bill savings by 302.6%.
