Stackable Battery Systems
Two module sizes — 5.12kWh and 10.24kWh — stack into systems from a single brick to 30kWh residences and small commercial stores, with a 5kW pure sine wave inverter stage on the system models.
The stackable range exists for one reason: capacity decisions change. A household that needs 10kWh today adds an EV next year; a small business starts with backup for the office and extends to the workshop. Stackable modules let the system follow the load — each brick is a complete 51.2V LiFePO4 unit with its own protection, and systems parallel one to six units in single or three phase.
Two bricks anchor the range. The 100Ah brick carries 5.12kWh in a 666 × 516 × 441mm enclosure at about 90kg; the 200Ah brick carries 10.24kWh at 600 × 500 × 619mm and about 140kg. Both are rated at 6,000 cycles or more at 80% depth of discharge, communicate over RS232, RS485 or CAN, and — in the published system configuration — work with a 5kW inverter stage: 120Vac single-phase output, 10ms switch time, a 5,500W PV input window and MPPT tracking efficiency of 99.9%.
Because the modules are the same ones used across the residential line, spares, expansion units and documentation stay consistent over the life of an installation. Order the second brick three years later and it is the same module, the same footprint and the same communication protocol.
