EA ENERGY's 51.2V 300Ah LiFePO4 battery is a high-performance solution for residential solar energy storage, designed to deliver 15.36kWh capacity (51.2V × 300Ah). Engineered with A-grade LiFePO4 cells, it ensures 6,000+ cycles at 80% depth of discharge (DoD), providing over 10 years of reliable service with minimal capacity degradation.
Key Features:
Modular Scalability: Supports parallel connections to expand capacity up to 15kWh, adapting to household energy demands.
Advanced Safety: Integrated smart BMS prevents overcharge, overheating, and short circuits, compliant with UN38.3 and IEC62619 certifications.
Robust Performance: Operates efficiently in -20°C to 60°C environments, featuring IP65-rated protection for dust/water resistance.
Eco-Friendly Design: Non-toxic LiFePO4 chemistry reduces environmental impact compared to lead-acid batteries.
Applications:
Ideal for off-grid solar systems, emergency backup, and peak-shaving, this battery integrates seamlessly with inverters via CAN/RS485 communication. Its plug-and-play design requires no maintenance, eliminating traditional lead-acid battery hassles like watering or equalization.
