Everything you need to know about choosing, installing, and using a home battery system - expert advice for making the right decision
A home battery, also called a home battery system or energy storage system, is a device that stores electricity for later use in your home. Think of it as a large rechargeable battery that you charge when electricity is cheap (or from your solar panels) and use when electricity is expensive or unavailable.
Modern home batteries use lithium technology (similar to your phone battery, but much larger and safer) to store energy efficiently. The most common and safest technology is LiFePO4 (Lithium Iron Phosphate), which offers excellent lifespan and safety characteristics.
Charge during low tariff hours, use during peak hours. Save €300-800/year on electricity costs.
Never worry about power outages - your essentials keep running during grid failures.
Store excess solar energy instead of selling it back cheap. Use it when you need it most.
Reduce your carbon footprint by optimizing renewable energy use and grid independence.
