Energy Storage Systems (ESS/BESS)
Supplier from China

E7REPOWER designs, configures, and supplies modern energy storage systems (ESS/BESS) that help businesses, developers, and utilities stabilize the grid, capture more value from renewables, and maintain resilient operations. We deliver factory-integrated solutions manufactured in China—paired with European compliance documentation, pragmatic engineering support, and logistics tailored for the world market. Whether you are sizing a containerized large-scale BESS for a solar farm or selecting a compact cabinet for a commercial facility, our team helps you move from specification to commissioning with clarity and speed.

What We Supply

• Industrial & Utility-Scale BESS: Containerized blocks (0.1–5 MW) for grid-tie, peak shaving, frequency response, and capacity firming.
• PV & Solar Storage: Hybrid configurations for rooftop PV and ground-mount plants, enabling self-consumption, export limiting, and TOU optimization.
• Lithium (LFP) Battery Equipment: Modules, racks, and cabinets with integrated BMS; modular architecture for scalable energy.
• Critical Components: PCS (bidirectional inverters), EMS, transformers, switchgear, monitoring and protection systems.
• Residential & Community ESS: Safe, compact solutions for homes, microgrids, and community resilience projects.

Why E7REPOWER

• Compliance-first approach: EU-ready documentation (e.g., CE) and IEC test reports where applicable.
• Engineering support: Sizing, single-line diagrams, commissioning guidance, and remote O&M.
• Transparent specs: Clear datasheets, realistic performance ranges, and grounded configuration notes.
• Scalable roadmap: Start with one container and expand as demand grows without redesign.

Inside a Modern BESS: Architecture That Works

Battery Chemistry

We focus on LFP (LiFePO₄) chemistry for its balance of safety, cycle life, and predictable behavior. Modular packs and racks simplify maintenance and scaling, while BMS enforces safe operating windows.

PCS (Power Conversion System)

Bidirectional PCS units connect the DC battery to the AC grid or facility. They enable charge/discharge, reactive power support, and fast response for grid services. Correct PCS sizing and transformer selection are critical for compliance.

EMS & Controls

The Energy Management System manages charging, peak reduction, TOU shifting, PV self-consumption, and ancillary service participation (where allowed). EMS integrates with SCADA via standard protocols.

Enclosure, Cooling & Safety

Containerized systems include liquid-cooling, fire detection, and protection. Ventilation paths, thermal management, and safe spacing ensure reliability and access. Safety devices and wiring match environmental and grid requirements.

Applications & Use Cases

• Commercial & Industrial: Reduce demand charges, flatten peaks, secure backup power, and improve cost predictability.
• Utility & Grid: Frequency response, energy arbitrage, load leveling, and renewable smoothing for stability and revenue.
• Solar + Storage: Boost self-consumption, reduce curtailment, increase ROI, and shift energy to peak price periods.
• Microgrids & Community: Islanding (where configured), local resilience, and critical load support.
• Data Centers & Logistics: Ride-through events, backup support, and improved power quality.

How We Size and Configure Your ESS

Every project begins with use-case definition. We size power (kW/MW) and energy (kWh/MWh), select PCS ratings, and define duty cycles. Ambient conditions, space, transformer needs, and grid codes are factored in. For long life, we recommend oversizing, charge-rate limits, and EMS strategies that reduce degradation while meeting ROI.

Delivery to Client: Practical Steps

1. Requirements intake: Site details, grid connection, duty cycle, safety rules, and schedule.
2. Configuration & Quote: Bill of materials, datasheets, and transparent quotation.
3. Documentation plan: EU-ready documents (e.g., CE) and IEC reports where applicable.
4. Factory testing: FAT scope agreed, with remote or onsite witness.
5. Shipping & Customs: EXW/CIF/DDU/DDP terms; tailored logistics for your site.
6. Commissioning & Handover: On-site support, training, and remote O&M onboarding.

Digital, Monitoring & Cybersecurity

We offer remote monitoring, performance analytics, and predictive alerts. EMS integrates with SCADA and third-party systems. Secure access and encryption protect data, with policies defined during kickoff.

Quality, Warranty & Service

From QA to site validation, our process reduces risks. Warranties are tied to defined operating windows and EMS strategies, with extended options available. Post-handover, we support via remote monitoring and scheduled reviews.

Sustainability in Practice

LFP chemistry ensures safe, long-lasting systems. Modular packaging reduces waste during upgrades. When possible, we link clients to regional recyclers for compliant end-of-life battery handling.
