- Grade A LiFePO4 cells. All new Grade A LFP cells provide stable, long-lasting performance — the chemistry of choice for residential energy storage because of its safety and service life.
- 6,000-cycle service life. Rated for ≥6,000 cycles at 25°C and 80% depth of discharge, with a 90% usable DOD, so the battery is built for daily charge and discharge over many years.
- Expandable to 15 units in parallel. Start with one K-WALL battery and add more later — up to 15 units can be connected in parallel to grow your home energy storage system as your needs change.
- Built-in BMS for a high level of safety. An integrated battery management system continuously manages each cell and supports safe indoor installation in a residential environment.
- Flexible communication options. CAN, RS485, RS232, Wi-Fi and Bluetooth interfaces make it easy to monitor the system and connect it to your energy setup.
- Space-saving wall-mounted design. The compact wall-mount form factor and home-appliance styling fit neatly in garages and utility rooms without taking up floor space.
- Wall-mounted installation with a compact footprint
- IP20 (IP54 optional) ingress protection
- Operating temperature 0–55°C; storage temperature −20–55°C
- Humidity ≤80%
- Grade A LiFePO4 cells with built-in BMS protection

How a Wall Mounted Home Battery Storage System Works
During the day, rooftop solar panels generate electricity and the K-WALL stores the surplus your home does not use immediately. In the evening, or when electricity rates are highest, the stored energy is discharged to power your home instead of drawing from the grid — helping you lower electricity bills and make better use of your solar investment. When configured with a suitable inverter, the battery can also provide backup power for essential loads during a grid outage.
