Industrial-Grade LiFePO4 Off-Grid Energy Storage Battery | OEM & ODM Solutions
Engineered for autonomous power systems, remote telecommunications, and independent solar installations, our Lithium Iron Phosphate (LiFePO4) Energy Storage Battery delivers reliable, maintenance-free power independent of the public grid. Built using Grade-A prismatic cells with a stable olivine crystal structure, our systems offer superior energy density, exceptional thermal stability, and deep-cycling longevity.
Compared to conventional lead-acid alternatives, our advanced lithium solutions feature an 80% to 95% usable Depth of Discharge (DoD), a round-trip efficiency exceeding 90%, and a footprint and weight reduction of up to 50%. As a direct factory manufacturer, we empower global distributors, EPC contractors, and system integrators with scalable energy storage, custom voltage architectures, proprietary BMS engineering, and comprehensive private-label (OEM/ODM) solutions.
Core Engineering Advantages
3,000 to 6,000+ Cycles via Premium LiFePO4 Chemistry
Cycle Performance: Delivers 3,000 to 6,000+ cycles at 80% DoD under standard operating conditions (25°C), translating to a proven operational lifespan of 10+ years in rigorous daily cycling applications.
Total Cost of Ownership (TCO): Drastically lowers the levelized cost of storage (LCOS) per kilowatt-hour, eliminating the frequent replacement and maintenance overhead associated with traditional 300-to-800 cycle lead-acid battery banks.
High Usable Capacity & Voltage Stability
Depth of Discharge (DoD): Supports up to 95% usable capacity. A 10 kWh nominal pack yields approximately 9 to 9.5 kWh of real, dispatchable energy.
Flat Discharge Curve: Maintains a steady voltage output curve throughout the discharge cycle, ensuring consistent DC input for connected inverters and preventing premature low-voltage tripping under heavy inductive loads.
Intelligent Hardware-Level BMS Integration
Every battery pack features a dedicated, highly configurable Battery Management System (BMS) for real-time telemetry and advanced cell protection:
Multi-Layer Electrical Protections: Comprehensive cutoffs for overcharge, over-discharge, short-circuit, and over-current scenarios.
Dynamic Thermal Management: Multiple internal temperature sensors automatically trigger safety mitigation if internal cells approach critical operating thresholds.
Active/Passive Cell Balancing: Continuously balances cell voltages during the charge cycle to prevent capacity drift and extend total pack longevity.
Seamless Inverter Ecosystem Compatibility
Multi-Protocol Support: Built-in physical and software support for RS485, CAN 2.0B, and Modbus communication protocols.
Closed-Loop Integration: Fully compatible with major off-grid and hybrid inverter brands (including Victron Energy, Growatt, Deye, and GoodWe), enabling closed-loop communication for automated charging voltage and current regulation.
Rugged Enclosure & Extreme Climate Adaptability
Industrial Build Quality: Heavy-gauge cold-rolled steel enclosures protected by a marine-grade, corrosion-resistant powder coating.
Environmental Ratings: Flexible packaging options available in IP20 (indoor rack/wall-mount) and custom IP-rated weatherproof outdoor cabinets.
Cold-Weather Operation: Optional internal heating film configurations permit safe, low-temperature charging down to -20°C.
