Optimised for New EnergyThe 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.
Over 3,000 1KOMMA5° Batteries sold across 6 European markets in less than a year.
VPP-Capable and Rebate-Ready!
Choose the 1KOMMA5° Battery and enjoy peace of mind knowing it’s VPP-ready and fully compliant with the upcoming federal solar battery rebate launching on July 1, 2025. That means you could save up to 30% or as much as $9,520 on your battery system.
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 7.7 to 27.2 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 VPP Optimisation
The 1KOMMA5° Battery is the Intelligent Workhorse of your home solar system. Designed to charge and discharge in small intervals (microcycles), our battery is optimised for VPP participation - truly utilising the ability of your home solar.
Power Outage Protection
When power outages or blackouts occur, the only thing keeping your lights on is solar battery storage. By including the 1KOMMA5° Battery within your home solar system, you can rely on your stored solar energy during events of power outages.
12 Year Warranty
The 1KOMMA5° Battery is backed by a 12-year product warranty, ensuring your home's solar storage performs to the expected level throughout its lifetime.
Heartbeat AI Ready
The 1KOMMA5° Battery is ready to be integrated with our soon launching intelligent energy manager, Heartbeat AI. Analysing real-time energy data, weather patterns and electricity market signals, Heartbeat AI connects your home solar system components to create an intelligent overall system.
Future-Proof Energy Storage
Unlike traditional batteries, the 1KOMMA5° Battery is designed to charge and discharge in small intervals, known as micro-cycles, for enhanced efficiency. It also features ultra-high data resolution, providing precise information about charge levels and power availability. With fast response times, the system can actively participate in virtual power plant (VPPs) programs to help stabilise the grid.
Optimised for Heartbeat AI
Designed for the evolving energy market, the 1KOMMA5° battery is designed for integration with AI-driven intelligence and advanced technology to redefine energy storage.
Our intelligent system management software, Heartbeat AI has helped thousands of homeowners achieve $0 power bills across Europe - and launching soon in Australia!
