Deye Low Voltage Wall Mount Battery Pack AI-W5.1-B

Description

Deye low voltage wall mount battery pack AI-W5.1 B is a lithium iron phosphate battery that can support reliable power for various equipment and systems. Perfect when installation space is limited, weight restrictions are present, and high power and long cycle life are needed.

This series has a built-in BMS battery management system, which can manage and monitor cell information, including voltages, current and temperature. What's more, BMS can balance cells charging to extend cycle life. Multiple batteries can connect in parallel for larger capacity and longer power supply.

This product must be installed by a registered electrician with a parallel generation/solar endorsement (from September 1st 2025) who can issue a Certificate of Compliance and Electrical Safety Certificate for completed work. AA Solar can provide this comprehensive service. Alternatively, we can work with your chosen SEANZ-endorsed installers and electricians, providing them with the products' Supplier Declaration of Compliance (SDoC) and the supporting documentation they need.
