Deye - AI-W5.1-B PDU1-B+Base
5kWh battery module for Deye All-In-One
Deye AI-W5.1-B PDU1-B+Base
SKU: AI-W5.1-B PDU1-B+Base
The Deye AI-W5.1-PDU1-B+Base is the primary power distribution and foundational mounting kit for the Deye AI-W5.1-B energy storage series. This integrated solution combines a high-capacity Power Distribution Unit (PDU) with a stable floor-mounting base to support modular battery stacking. The PDU serves as the master control interface, facilitating both high-voltage power transfer and critical data communication between the battery stack and the hybrid inverter. Designed for rapid deployment, it features a tool-free, wire-free stacking architecture that supports flexible expansion from 5kWh to 30kWh per string. The unit is engineered with industrial-grade safety components and an intuitive LED monitoring system to ensure reliable operation in both residential and commercial environments.
Key Features Deye AI-W5.1-B PDU1-B+Base:
- Centralized Distribution: Manages the power and communication link between modular battery units and the hybrid inverter for seamless system integration.
- Enhanced Safety Protection: Features a built-in 250A 2-pole circuit breaker rated for 1000Vdc, ensuring robust electrical protection for the entire stack.
- Intelligent Monitoring: Equipped with an 8-LED master indicator panel, providing dedicated status updates for State of Charge (SOC 20%–100%), active operation, and alarm protection.
- Modular Stackability: Part of a flat and stackable design that enables no-wire installation between battery modules, significantly reducing commissioning time.
- Foundational Stability: Includes a dedicated 6.5kg battery base that provides a secure, load-bearing floor mount for up to six modules.
- Environmental Resilience: Housed in an IP65-rated enclosure (once stacked) to support reliable performance across a wide operating temperature range.
- Advanced BMS Networking: Facilitates automatic networking of battery modules, simplifying maintenance and enabling remote firmware upgrades.
