Deye AI-W5.1-PDU1-B PDU with BMS for AI-W5.1-B Batteries

The Deye AI-W5.1-PDU1-B is a power distribution unit (PDU) with built-in BMS for AI-W5.1-B battery modules. It links the module stack to a hybrid inverter through a power and communication interface (CAN2.0 / RS485) and scales up to 6 clusters in parallel (36 modules), up to 184 kWh. It is equipment for system integrators building multi-module battery cabinets, not a standalone purchase for a single battery.

Technical specifications

What is a Deye PDU with BMS used for?

The AI-W5.1-PDU1-B is the control and switching unit that connects a stack of AI-W5.1-B battery modules to a hybrid inverter. It is meant for integrators assembling multi-module battery cabinets. The integrated BMS provides full protection, while 5 SOC LEDs (charge level 20–100 %) and 3 status LEDs (operation, fault, protection) show the state of the system.

Which Deye batteries and inverters does it work with?

It works only with Deye AI-W5.1-B battery modules; it is not a universal accessory for other battery models. It connects to the hybrid inverter through a power and communication interface, using CAN2.0 / RS485. We will select a suitable combination with your inverter based on your system.

How many battery modules and how much capacity can be connected?

The system can be expanded to 6 clusters in parallel, which is up to 36 modules. Maximum system capacity is 184 kWh. The design is modular, so the system can be extended.

We can help you choose. Hybrid Energy will check compatibility with your Deye batteries and inverter and select the modules and PDU you need.

How is the PDU installed and how is the system monitored?

The PDU mounts on top of the battery module rack and needs no additional wiring: the modules network themselves and receive IP addresses, so the system can be monitored remotely. IP65 protection applies when the unit is installed in the rack; cooling is natural and the operating temperature is −20 °C to +55 °C.

What to know before buying

• Compatibility: AI-W5.1-B modules only.
• Purpose: multi-module cabinets, not a single battery.
• Inverter: a hybrid inverter is required to connect the battery stack to.
• Communication interface: CAN2.0 / RS485.
