LiFePO4 Off-Grid Storage Battery

Engineered for residential, commercial, and industrial off-grid power systems, our LiFePO4 energy storage batteries deliver reliable, independent power without reliance on the public grid. Built with Grade-A Lithium Iron Phosphate (LiFePO4) prismatic cells, these systems provide stable capacity retention, high round-trip efficiency, and extended service life for solar setups, remote telecom sites, farms, and microgrids.

As a direct manufacturer, we offer scalable production capacity, customizable voltage/capacity configurations, and full OEM/ODM support for solar installers, distributors, and energy system integrators.

6,000+ Cycle Life & Cost Efficiency
Performance Metric: Up to 6,000+ charge/discharge cycles at 80% Depth of Discharge (DOD) under standard operating conditions.

Installer & Distributor Benefits: A 10+ year operational lifespan significantly reduces warranty replacement rates, lowers maintenance overhead, and delivers a lower Total Cost of Ownership (TCO) for end users compared to traditional lead-acid alternatives.

High Energy Efficiency & Deep Discharge
Round-Trip Efficiency: Achieves 90%-95% efficiency, minimizing energy loss during the charging and discharging phases.

Usable Capacity: Supports up to 90% DOD without voltage sag, allowing installers to maximize usable stored energy and reduce the total number of battery units required per installation.

Integrated Smart BMS (Battery Management System)
The built-in hardware BMS provides real-time monitoring and active protection across all operational parameters:

Monitored Parameters: Cell voltage, charge/discharge current, internal temperature, State of Charge (SOC), and State of Health (SOH).

Protective Actions: Automatic cutoff for overcharge, deep over-discharge, over-current, short-circuit, and extreme temperatures.

Inverter Communication: Supports standard CAN and RS485 communication protocols for seamless integration with hybrid and off-grid solar inverters (compatible with major brands such as Deye, Victron, Growatt, etc.).

Thermal Stability & Wide Operating Range
Chemistry Safety: LiFePO4 chemistry features a stable olivine crystal structure, eliminating the risk of thermal runaway under normal stress.
Temperature Tolerance:
Charging: 0°C to 45°C
Discharging: -20°C to 55°C

Modular & Scalable Architecture
Supports parallel and series configurations to scale energy storage capacity from 5kWh residential units to 50kWh+ commercial banks.

Standardized form factors (wall-mounted, rack-mounted, and floor-standing cabinets) simplify logistics, inventory management, and on-site installation.

Residential Solar Storage: Ideal for remote homes, rural electrification, and zero-grid properties requiring reliable nighttime backup and self-consumption optimization.

Commercial & Remote Industrial Power: Provides stable power for remote monitoring stations, telecom cellular towers, agricultural irrigation systems, and mining/construction sites, replacing noisy diesel generators.

Solar Microgrids: Balances renewable energy generation and load demand fluctuations in community-scale microgrid setups.

To meet the rigorous compliance demands of global markets and institutional buyers, our manufacturing lines strictly adhere to international quality frameworks. Our battery packs undergo comprehensive factory testing, including cell grading, pack aging, and functional verification prior to shipment, holding major industry certifications including UN38.3, CE, IEC62619, and RoHS.

We provide comprehensive private-label and technical customization for global energy brands and distributors:

Electrical Customization: Tailored voltage, capacity, and BMS discharge current limits to match specific inverter requirements.

Mechanical Design: Custom sheet metal enclosures, front panel branding/logo printing, custom terminal placement, and specialized packaging.
