5kWh Stackable Battery
The 100Ah brick: 5.12kWh per module, the starting unit of the stackable range and the expansion unit for every system built on it.
The 5kWh stackable battery is the module the residential range is counted in. Each brick is a complete 51.2V 100Ah LiFePO4 unit storing 5.12kWh, rated at 6,000 cycles or more at 80% depth of discharge — and despite the '5kWh' shorthand used across the industry, the datasheet figure is the honest 5.12kWh you get from 51.2 volts times 100 amp-hours.
In its published system configuration the brick works with a 5kW inverter stage: 5,000W rated output at 120Vac single phase, pure sine wave, 10ms switch time, and a PV input accepting up to 5,500W with a 125–450Vdc MPPT window and 99.9% tracking efficiency. Mains or generator charging runs at up to 40A, hybrid charging at 100A, and one to six units parallel in single or three phase — so the same module that starts a 5kWh backup job grows into a 30kWh whole-home system.
Installers standardise on this brick because the decision it removes is the future one: when the household adds an EV or a heat pump, the expansion is another identical module, not a replacement. Distributors stocking one module cover the entry system, the mid-size system and the expansion market with a single SKU.
