System Architecture

ESS Architecture: Battery + Inverter + EMS + Grid

Every EMoreShare energy storage system is architected from the ground up — combining LFP battery technology, hybrid power conversion, intelligent energy management, and grid-interface design into a single, deployable system.

We are manufacturer-independent, selecting each component based on project requirements rather than product constraints.

Battery System — LFP Chemistry

We exclusively specify LiFePO₄ (LFP) battery chemistry for commercial and industrial energy storage applications.

LFP offers superior cycle life (6,000+ cycles at 80% DoD), high thermal stability, and a chemistry profile that eliminates cobalt-related safety concerns — making it the standard choice for stationary C&I storage worldwide.

Cell-level monitoring, intelligent cell balancing, and modular rack design ensure that capacity degradation curves remain predictable and warrantied over a 10-year performance period.

Hybrid Inverter — Power Conversion System (PCS)

The bidirectional hybrid inverter manages energy flow between the battery, the AC load, the grid, and optional on-site generation (solar PV or diesel).

Modern C&I hybrid inverters operate in grid-following or grid-forming mode, enabling:

Peak shaving — discharge during peak tariff windows
Energy arbitrage — charge off-peak, discharge peak
UPS/resilience mode — seamless grid-to-backup transition
Grid support — reactive power, frequency response

Sizing is typically 40–60% of battery kWh capacity, enabling 2–4 hours of full discharge at rated power.

Energy Management System — Cloud + Edge

The EMS is the intelligence layer of the ESS — continuously optimizing when to charge, when to discharge, and how to balance financial returns against grid constraints and battery health.

Our standard EMS architecture combines:

Edge controller — real-time local dispatch, sub-second response
Cloud platform — remote monitoring, analytics, OTA updates
Day-ahead tariff integration — forecast-optimized dispatch
Multi-site management — single dashboard for portfolio-scale assets

Operator access via web portal and mobile app. API available for integration with building management systems (BMS) and utility portals.

📊 ROI impact: Day-ahead tariff optimization drives the arbitrage differential — the core revenue engine of every ESS project.

Grid Interface & Safety Systems

Every EMoreShare ESS is designed to meet the interconnection and safety standards required in the target deployment market — from European CE requirements to country-specific grid codes.

Grid Interface includes:

• Grid-tied or island mode operation with automatic transfer
• Anti-islanding protection (per IEC 62116)
• Reactive power compensation and power quality management
• Remote grid connection/disconnection capability

Integrated Safety System includes:

• Multi-stage battery protection (over/under voltage, overcurrent, thermal)
• Fire detection and suppression (HVAC-linked gas detection)
• DC isolation monitoring and AC/DC circuit breakers
• Emergency stop and rapid shutdown per local regulations
