Storage size in kWh
Keep scrolling or tap a size.
The storage grows in steps of 10 kWh. One tower holds up to three battery modules. With three full towers, you get 90 kWh.












Modular
Everything in one tower. Modular and expandable.
Inverter, distribution box and up to three battery modules sit on top of each other. If your home needs more storage later, another module is added.
Design
Beautiful from every side.

Features
More inside than meets the eye.



Charge level at a glance
20 segments of 5 percent each show the battery's state of charge or the current power. The symbol at the bottom shows which of the two is currently displayed.
Ready for the next tower
On the left and right of the distribution box are the power and communication connections for additional battery towers.
Every status clear at once
Five indicators on the distribution box report state of charge, alarm, operation, charging and discharging. The on/off switch sits next to them.
Plugged, not wired
Each battery module stores 10 kWh. A tower holds up to three modules, connected by plug connectors at the top and bottom.
All connections behind one lockable door
On the right of the inverter, behind a lockable door, are the PV switch and the connections for three module strings on two MPP trackers, for grid, backup power and generator. There are also connections for Wi-Fi, meter and communication.
Safely disconnected in one move
The DC switch sits on the right of the distribution box. It disconnects the tower's batteries from the system.

Backup power
Your backup circuit keeps running.
≤ 10 msSwitchover time to backup power
If the grid goes down, the system switches to backup power within 10 ms and supplies the devices on your backup circuit.
Backup circuit or whole home?
Backup circuit
Selected circuits. The system switches over automatically within 10 ms, with nothing for you to do. The devices on your backup circuit keep running, with up to 10 kW.
Whole home
With a changeover switch, you switch the whole house over to the storage system by hand. All circuits then keep running, as long as together they draw no more than 10 kW.

Installation
Basement, garage or outside wall.
The storage system stands on the floor and is secured to the wall at the top. In a garage, it needs distance from anything flammable. Outdoors, it needs a spot out of direct sunlight.
Dust-tight and protected against powerful water jets.
The system operates with batteries in this temperature range.
Plenty of power. Barely a sound.
