ONÉA BLOCK
A battery that belongs on the wall.
BLOCK is a 5 kWh module with a quiet housing and a four-cell indicator you can read from across the room. Hang one, add more, and let CORE do the rest.
- Nominal, per module
- 5 kWh
- Modules on one CORE
- 1–4
- Hang, slide, lock

Configure
Start with one. Stack to four.
Modules sit side by side on a single rail next to CORE. The drawing is to scale with itself, not with any real product.
10 kWh
Nominal capacity
Two modules — room for a display fridge alongside the essentials.
Details
Made to be lived with.
The indicator
Four cells behind a frosted window. Lit means stored; a slow pulse means it is supplying the shop.
The housing
A satin anodised aluminium shell with softened edges — no vents on the face, nothing to catch dust.
The rail
One steel rail carries CORE and up to four modules. Each module hangs, slides and locks.

ONÉA CORE
One box decides where the energy goes.
CORE is a hybrid inverter. It connects the grid, BLOCK, solar and a generator to the loads in your business, and switches between them on its own.
How it flows
Four sources, one decision.
The grid runs the shop. CORE tops BLOCK up quietly in the background.
ONÉA Companion
The app you hardly need to open.
Companion tells you when the grid has gone, what is running, and how much is stored. Nothing more than you need.
