Deye AI-W5.1-B Lithium Battery 5.12kWh 100Ah LiFePO4 IP65

Product Description

The Deye AI-W5.1-B 5.12kWh 100Ah LiFePO4 IP65 Lithium Battery is a 48/51.2 V LFP storage module designed for vertical stacking, scalable growth, and maximum reliability in residential self-consumption and small commercial applications. Its integrated BMS, robust format, and IP65 protection rating allow installation in demanding indoor environments or protected outdoor areas, ensuring electrical safety, long service life, and quick integration with 48 V hybrid inverters via CAN/RS485 communication.

Main Features

• Nominal energy per module: 5.12 kWh (51.2 V / 100 Ah); typical usable ≈4.6 kWh (DoD 90%).
• LiFePO₄ (LFP) chemistry without cobalt: high thermal stability and safety.
• IP65 protection rating for the stacked unit; suitable for wall or floor installation.
• Integrated BMS with full protections and balancing; CAN2.0/RS485 communications.
• Nominal current up to 100 A per module; short peaks up to 150 A (25 °C).
• Cycle life ≥6000 cycles (25 °C, 0.5C/0.5C, DoD 90%, EoL 70%).

Advantages or Benefits

• Safety first: LFP chemistry reduces thermal risk and offers stable operation for years.
• True scalability: stack 1 to 6 modules per cluster (up to 30.72 kWh nominal) and parallel clusters for expansion.
• Savings and autonomy: store solar surplus for use in the evening/night, reducing grid purchases.
• Minimal maintenance: front access, LED diagnostics, and intelligent BMS management.
• Simple integration: standard connectivity and PDU/Base/Cables kit that reduces installation time.

Purpose or Applications

The Deye AI-W5.1-B 5.12kWh 100Ah LiFePO4 IP65 Lithium Battery is perfect for homes with self-consumption, businesses seeking backup for critical loads (lighting, routers, pumps), and projects with time-shifting or peak-shaving strategies. It is also suitable for upgrades of existing 48 V systems thanks to its stackable format and communication compatibility with current hybrid inverters.
