Description:
Our Solar Power Systems with Battery Storage provide a high-performance and reliable solution for utility, commercial, and residential applications. This 1MWh LiFePO4 Battery Energy Storage System integrates a state-of-the-art EMS system, advanced BESS design, and modular container structure, ensuring safe, stable, and efficient energy management across multiple scenarios.
Features:
1. Longer Cycle Life
Up to 20× longer cycle life and 5× longer float/calendar life than lead-acid batteries, significantly reducing replacement cost and total cost of ownership.
2. Lighter Weight
Only 40% of the weight of a comparable lead-acid battery. A true “drop-in” replacement with better energy utilization.
3. Higher Power Output
Delivers double the power of lead-acid batteries even under high discharge rate while maintaining strong energy capacity.
4. Wide Temperature Range
Reliable performance from -20℃ to 60℃, suitable for harsh outdoor environments.
5. Superior Safety
LiFePO4 chemistry eliminates explosion or combustion risk caused by impact, overcharge, or short circuit. Integrated BMS ensures multi-level protection.
6. Modular & Scalable Design
Deploy up to 4 batteries in series and up to 10 batteries in parallel, enabling flexible capacity expansion for any project requirement.
7. Advanced EMS System
Real-time monitoring, optimized battery scheduling, peak-shaving, and load-shifting for maximum operational efficiency.
