5.1kWh stackable LiFePO4 battery for residential backup and time-of-use storage.
PowerVault 5.1 is built on LiFePO4 chemistry for a long cycle life and strong thermal stability — a meaningful safety margin over legacy lead-acid banks in enclosed indoor installations.
Units are stackable, so a system can start at one PowerVault and scale to three or more in parallel as backup needs grow, without replacing existing hardware.
