HomeGrid | Stack'd Base and BMS Controller
Overview
This modular home battery system expands in 4.8 kWh increments, allowing each Stack to range from 9.6 to 38.4 kWh. Its design supports easy maintenance and future upgrades. With a continuous power output of up to 15 kW and surge capability of 24 kW for 10 seconds, it delivers true whole-home backup with a quick 30–60 minute installation.
For capacity upgrades, it's best to add new modules within 10 years of the original setup. Thanks to active module balancing by the system’s BMS, new modules don’t require voltage matching—the system automatically manages it. Keep in mind, firmware updates may be required to match new modules.
Each Stack can hold up to 8 modules, and up to 15 Stacks can be connected in parallel. Heated modules are also available for colder environments, but mixing heated and non-heated units isn’t recommended.
*This listing is for the BMS and base of the Stack’d Series. A minimum of 2 modules is required. Please see our Stack’d Series module listing to complete your system.
