Description
Modules sit on top of each other, and the stack goes on the floor or onto the wall when floor space is tight. Each module delivers up to 100 A, which is 5.12 kW at 1C, and in a parallel build the allowable current and power grow with the module count. The 48 V rating matches low-voltage hybrid and off-grid inverters with a battery bus at that voltage. The LiFePO4 cells withstand at least 8,000 cycles. An aerosol extinguisher built into the housing puts out a fire inside the module. The battery talks to the inverter over CAN or RS485, while Wi-Fi and the app show the owner state of charge and module status.
How to choose
Size the module count from daily consumption and the inverter peak power, keeping in mind that one module carries 5.12 kW. A house usually needs only a few modules, while the 256 kWh ceiling suits a small business facing long outages. For an outdoor build, look at the PowerDepot series, and where a high-voltage stackable system fits better, STACK100 offers 15.36–76.8 kWh per cluster.
