Build a home battery system that can grow with real energy needs. The Deye AI-W5.1-B ESS starts from a 5.12kWh LiFePO4 battery module and scales into a larger residential storage system, giving households a clean way to store solar energy, support backup power, and prepare for future energy demand.

Made for tidy, expandable residential storage. Stackable low-voltage battery modules keep the installation compact, while the system architecture supports up to 36 modules for projects that need much more than a single starter battery.

Reliable chemistry for everyday use. LiFePO4 battery technology, IP65 protection, 97.6% maximum system efficiency, and 6,000+ cycle life at 70% EOL make the AI-W5.1-B ESS a practical choice for long-term home energy storage projects.

Choose the right system with your installer. Final configuration depends on the selected PDU, inverter, local installation requirements, and the number of battery modules required for the home.

Final battery module quantity, PDU selection, inverter compatibility and installation accessories should be confirmed before ordering.
