Stackable ESS, 5.12–40.96 kWh.
The battery grows with the load. Each 5.12 kWh LiFePO4 module locks onto the one below it with a toolless one-click autolock, scaling from a single module to eight — 40.96 kWh — in a five-minute assembly. The stack pairs with the 5 kW-and-below entry inverter and shares the same 5.12 kWh battery module used across the wall-mounted range.
Add capacity without rewiring.
Modules interlock mechanically before any cable is touched, so capacity can be added in the field without re-cabling the existing stack. A 150 kg-rated set of universal wheels on the base lets a loaded stack be repositioned by one person.
- Toolless one-click autolock between modules
- 1–8 modules · 5.12 to 40.96 kWh
- Universal wheels rated 150 kg
- LiFePO4 · 10,000 cycles at 100% DOD (0.2C, 25 °C)
- 10-year design lifespan
- 0 V ports until assembled, for safe transport
One module at a time, up to eight.
Capacity steps in clean 5.12 kWh increments. Each module is 600/420/200 mm and 54 kg; the base adds 600/420/130 mm and 17.5 kg underneath.

The stack is a DC battery that pairs with the 5 kW-and-below entry inverter, which provides the MPPT charge controller, the 10 ms switchover and the grid interface. Because every module carries its own BMS, a fault is isolated to a single layer and the rest of the stack keeps running while the unit is swapped.
From pallet to power in three steps.
Unbox
Modules arrive with terminals at 0 V. Set the 17.5 kg base on its wheels, then lift each 54 kg module into place.
Stack & lock
Lower each module onto the one below it — the one-click autolock engages mechanically with no tools and no separate wiring.
Connect three cables
Run the color-coded DC and communication lines into the foolproof sockets, then power on. Assembly takes about five minutes.
A stack you can read at a glance.
Each module carries its own BMS, so a fault is isolated to one layer and the rest of the stack keeps working while the unit is swapped. The SOC breathing light on each layer shows charge state at a glance — blue, green and yellow for normal operation, red for a fault.
Stackable, answered.
One to eight modules, for 5.12 to 40.96 kWh of usable capacity. Beyond eight, contact sales — larger sites are usually served by the rack-cabinet line with parallel packs.
The stackable is a battery stack that pairs with the 5 kW-and-below inverter; the wall-mounted unit integrates the inverter, MPPT and battery in one wall-hung enclosure. The two share the same 5.12 kWh battery module (600/420/200 mm, 54 kg), so a distributor can stock one module and serve both lines.
Yes. The positive and negative terminals are disabled at 0 V until the stack is assembled, which protects shippers and installers during transport. Modules are UN38.3-compliant for sea and air freight.
