Solis Deploys Mexico's First EverCore C&I Energy Storage System, Empowering Industrial Energy Resilience

GUADALAJARA, JALISCO, MEXICO – November 2026 – Solis, a global leader in solar inverter and energy storage technologies, announces the successful installation of its first SolisStorage EverCore Commercial and Industrial (C&I) Energy Storage System in Mexico, at LETSA Láminas, a manufacturer of translucent plastic sheets based in Guadalajara, Jalisco.

Installed by Solar Technology México, with the participation of Solar Center, the project demonstrates how integrated solar-plus-storage solutions can help Mexican manufacturers maintain production continuity, reduce exposure to grid interruptions, and improve energy management.

For LETSA Láminas, unexpected power outages had become more than an inconvenience. Interruptions affected production schedules, required additional equipment cleaning and restart procedures, and created challenges in meeting customer orders during periods of high demand. Power reliability was particularly important during the rainy season.

The installation of EverCore provides an additional layer of energy security, helping the manufacturer maintain more stable operations while making better use of its available solar energy.

EverCore: Six Core Technologies Designed for Industrial Energy Storage

At the heart of the project is the SolisStorage EverCore 261 kWh / 125 kW C&I Energy Storage System, combining battery storage and hybrid power conversion in an integrated platform engineered for demanding industrial applications.

EverCore brings together six core technologies that address key priorities for C&I energy storage installers and industrial customers: installation efficiency, system integration, environmental adaptability, maintenance, safety, and intelligent energy management.

1. Separated AC and DC Architecture – Simplified Installation and Flexible Expansion

EverCore adopts a separated AC and DC architecture that enables a plug-and-play installation approach. Factory-preinstalled battery-side wiring and familiar PV installation methods help simplify on-site work and commissioning.

The architecture also supports flexible AC and DC expansion, allowing installers to plan scalable energy storage configurations as customer requirements evolve.

2. Integrated Four-in-One Power Electronics – Simplified System Integration

EverCore integrates PCS, PV integration, static transfer switching (STS), and energy management (EMS) into a centralized power electronics platform.

With no additional STS module required, the system supports seamless grid-connected and off-grid switching with a backup response time of less than 10 milliseconds. It also supports AC and DC coupling, PV system expansion without replacing existing PV inverters, and up to 2× available PV capacity.

For installers, this integrated architecture means fewer additional components and a more streamlined system configuration.

3. All-Environment Design and Optimized Thermal Management – Reliable Performance in Demanding Conditions

Industrial energy storage systems must operate reliably across different climates and installation environments.

EverCore features IP55-rated battery cabinet protection, an IP66-rated hybrid inverter, and C5 anti-corrosion protection. Its operating temperature range is -25°C to 55°C, with support for installations at altitudes of up to 4,000 meters.

Its triple-layer thermal management design, incorporating an independent three-air-duct cabinet structure and optimized airflow, improves thermal management efficiency by up to 30%.

4. Easy Maintenance and Lower Operating Costs – Designed with Installers in Mind

EverCore's air-cooled architecture and integrated design simplify system maintenance and reduce operational complexity.

Key components are designed for easier diagnosis and replacement, with general-purpose tools and a two-person operation approach helping reduce service requirements and labor costs.

The system also incorporates maintenance-oriented component designs, including a 10-year calibration-free combustible gas detection feature, helping reduce routine maintenance demands.

5. Triple-Layer System Safety Protection – Comprehensive Protection from Cell to System

Safety is fundamental to commercial and industrial energy storage.

EverCore adopts a three-layer safety architecture covering battery cells, battery packs, and the overall system, supported by a 15-level system safety protection design.

Protection measures include temperature and smoke detection, multi-level electrical protection, aerosol fire suppression, thermal insulation between battery packs, and additional explosion-protection provisions.

The battery cells are engineered for a cycle life exceeding 8,000 cycles while retaining 70% of rated capacity under the manufacturer's specified test conditions.

6. Open Software Platform and Broad Compatibility – Smarter Energy Management

Through SolisCloud, installers and system operators can access remote system monitoring, cell-level information, and wireless software updates.

Solis AI further supports multi-source forecasting, intelligent energy decision-making, and optimized energy dispatch to help improve energy utilization and operating economics.

The open software architecture also supports third-party EMS and VPP integration, providing flexibility for different energy management requirements and future system development.

Together, these six technologies make EverCore an integrated C&I energy storage solution designed to simplify deployment, improve system reliability, and support long-term operational value.

Real-World Results: Greater Confidence for Industrial Operations

Since commissioning and system testing, LETSA Láminas has reported a positive operational experience, particularly in reducing disruptions associated with electrical failures.

“Since the Solis BESS system was installed, we no longer have to worry as much about electrical failures during the rainy season. We have experienced fewer production stoppages caused by power failures, as well as fewer cleaning-related interruptions resulting from unexpected shutdowns. We are very pleased with the results following commissioning and testing,” said a representative of LETSA Láminas.

For industrial manufacturers, even a short power interruption can affect production efficiency, equipment operation, and delivery commitments. By integrating battery storage with solar generation, EverCore provides an additional layer of backup power and greater flexibility in managing available energy.

The LETSA Láminas project demonstrates how a properly configured C&I energy storage system can address real operational challenges while creating opportunities for better energy management.

Creating New Opportunities for C&I Installers Across Latin America

As industrial businesses across Latin America seek greater energy reliability, improved cost management, and more effective use of renewable energy, demand for integrated commercial and industrial energy storage solutions continues to create opportunities for solar installers and energy solution providers.

For installers, EverCore offers more than battery capacity. Its integrated power electronics, simplified installation architecture, comprehensive safety design, and intelligent energy management platform provide a complete solution to address industrial customers' evolving energy requirements.

Whether supporting backup power, integrating existing PV installations, or developing scalable solar-plus-storage projects, EverCore provides a flexible platform for installers to expand their C&I solution portfolios and explore new business opportunities.

The LETSA Láminas installation marks an important milestone for SolisStorage in Mexico and demonstrates the practical value of bringing advanced energy storage technology to local industrial applications.

Solis extends its appreciation to LETSA Láminas, Solar Technology México, and Solar Center for their collaboration in making this project possible.
