FES-512 Fusion 51.2V 100Ah (5.12kWh) LiFePO₄ Battery Module

Why Choose Fusion FES-512?

• Longer Cycle Life: Up to 10,000 cycles @ 50% DoD, 6,000 cycles @ 80% DoD, 2,000 cycles @ 95% DoD — minimises replacements and total cost of ownership.
• More Usable Energy: High usable capacity even at elevated discharge rates, outperforming lead-acid alternatives.
• Advanced BMS Protection: Under/over-voltage, current and temperature protections for safe, efficient operation.
• Safety First: LiFePO₄ chemistry with high-temp thermal fuse and flame-retardant additives.
• Scalable Architecture: Parallel connection up to 81.92kWh (cabinet-mounted, ground configuration) with straightforward install.
• Clear Visuals: Per-module LCD shows voltage, current, state of charge (SOC), and temperature.
• Broad Compatibility: Integrates with standard inverters, MPPT solar charge controllers, and energy management systems.

🔋 What is a lithium ESS Module Battery ?

A lithium energy storage system (ESS) module designed for residential, commercial, and utility-scale solar and backup power.

Each unit provides 5.12kWh of usable energy at 51.2V nominal (commonly called 48V)

Multiple modules can be connected in parallel up to 81.92kWh, making it highly scalable.

Uses LiFePO₄ chemistry, which is safer, more stable, and longer lasting than older lithium or lead-acid batteries.

⚙️ Key Features

Long Cycle Life:
Up to 10,000 cycles at 50% depth of discharge (DoD), 6,000 cycles at 80% DoD, and 2,000 cycles at 95% DoD.
→ That’s 10–15+ years of service life depending on usage.

High Performance:
Maintains strong energy delivery even at higher discharge rates.

Advanced BMS (Battery Management System):
Built-in protections for over/under-voltage, over-current, and high/low temperatures.

Safety:
LiFePO₄ chemistry is naturally stable, with flame-retardant additives and thermal fuses for extra security.

Scalability:
Can be paralleled for larger systems — from a single home battery to a large commercial bank of 80+kWh.

Integration Ready:
Works with industry-standard inverters, MPPT solar charge controllers, and energy management systems.

User-Friendly:
LCD display on each module shows voltage, current, SOC (state of charge), and temperature.

Durable Housing:
Enclosed in a weather-resistant, ground-mounted cabinet with a lockable door and UV-resistant glass.

🏡 Where It’s Used

Residential: Off-grid homes, hybrid solar systems, or as battery backup during outages.

Commercial: Energy storage for peak shaving, reducing grid demand charges, and backup power.

Utility-Scale: Large modular systems for solar farms or microgrids.

Retrofits: Upgrade from old lead-acid banks to modern lithium storage.
