More Info
The HomeGrid Stack’d Series BMS & Base Standard All Weather (Model 4000044) is the core component required to operate any HomeGrid Stack’d battery system.
It integrates a floor-standing mounting base with a Battery Management System that controls communication, safety, charge/discharge, and inverter compatibility for up to eight battery modules per stack.
This unit supports stacking up to 15 stacks in parallel, enabling a total system capacity of up to 576 kWh for large-scale energy storage solutions.
The BMS communicates in real-time via CAN and RS485 protocols, ensuring efficient system monitoring and management.
Designed with an IP55 rating, the base unit is suitable for indoor and covered outdoor installations, providing protection against dust and water jets.
It is compatible with both the standard and heated HomeGrid 4.8 kWh LiFePO₄ battery modules, allowing flexibility in module selection and installation environments.
The system works with a variety of major inverter brands including Sol-Ark, Schneider Electric, SMA Sunny Island, Victron Energy, and Outback Power, facilitating easy integration into existing setups.
Safety certifications include UL 1973, UL 9540, UL 1642, and UN 38.3, ensuring compliance with industry standards for residential and commercial energy storage.
Each stack must have exactly one BMS/Base unit to manage safety, communication, and energy flow effectively.
Battery modules are sold separately and can be mixed between heated and standard types within the same stack if needed.
