Optimised for Heartbeat AI The 1KOMMA5° Battery
Smarter Storage. Maximum Savings.
The 1KOMMA5° Battery is built for the future of energy. Whether starting your renewable journey or upgrading an existing system, this modular, scalable battery grows with your household and adapts to your evolving energy needs.
Precision-designed in Germany and purpose-built for the Australian grid, it responds in milliseconds to optimise how and when you use energy. That means greater self-sufficiency, smarter savings, and even opportunities to earn from your stored energy.
Thanks to microcycling technology, the battery can perform multiple rapid charge and discharge cycles throughout the day. That means it can respond to changing electricity prices and grid signals in real time, maximising your savings and reducing your reliance on the grid like never before.
Thousands of 1KOMMA5° Batteries are installed and live across Australia and 6 European markets.
What makes the 1KOMMA5° battery different?
German Designed & Engineered
Precision-designed and engineered in Germany, the 1KOMMA5° Battery has been rigorously tested and simulated in our Berlin tech lab to deliver exceptional performance, tailored for Australia’s toughest conditions.
Built with IP65-certified LFP technology, it offers robust reliability and durability, even in extreme weather.
Stackable, Modular Design
The 1KOMMA5° Battery offers seamless scalability, catering to your energy needs as they grow. It features scalable storage from 9.3 to 41.9 kWh and charging power up to 20.16 kW. Designed for flexibility, the 1KOMMA5° Battery accommodates two to nine modules to meet a range of energy storage requirements.
Microcycle Technology
