Sunsynk Elite Power Distribution Unit and Base

Key Benefits

• Centralises battery communication, protection and power distribution for each Sunsynk Elite stack, keeping installs tidy and easy to service.
• Designed to work seamlessly with Sunsynk Elite stackable 5.1 kWh batteries for fast, modular system build‑outs.
• IP65‑rated outdoor-ready solution when paired with compatible Elite batteries and inverters, ideal for UK commercial and light industrial sites.

Product Overview

The Sunsynk Elite Power Distribution Unit (PDU) and Base is the core control and connection module for each stack of Sunsynk Elite 5.1 kWh batteries. It manages communication, fusing and bus connections, so you can build safe, scalable battery towers without running separate harnesses for every module.

This PDU and base is intended to be used as part of a Sunsynk Elite system with compatible Elite hybrid inverters and Elite stackable batteries. It suits logistics hubs, light industrial units, commercial offices and small warehouses looking to add modular battery storage for self‑consumption and backup. Professional installation by a qualified electrician or solar installer is strongly recommended.

Key Features 

• Dedicated PDU for each Sunsynk Elite battery stack, providing control, protection and communication for the connected 5.1 kWh battery modules.
• Supports multiple stackable battery modules per PDU (see battery and inverter datasheets for the exact maximum configuration).
• Integrated base provides a stable mounting platform for the battery stack, helping to keep the tower aligned and secure.
• Designed for use with Sunsynk Elite single‑phase hybrid inverters and compatible low‑voltage LiFePO₄ battery modules, creating a neat, modular ESS.
• Suitable for indoor and, when installed to manufacturer guidelines with compatible equipment, outdoor applications thanks to the Elite system’s IP65‑rated components.
