A battery stores excess solar for evening use, increasing self-consumption to 80-90%. ### Estimated Savings by Household Type - Low usage household: £300-£450/year - Medium usage household: £450-£650/year - High usage household: £650-£900/year - With solar panels: Additional £200-£400/year --- ## Frequently Asked Questions **Q: Do I need solar panels to use a home battery?** A: No. AEG batteries are AC-coupled and work independently of solar. You can charge from the grid using cheap off-peak electricity. **Q: How long does installation take?** A: The AEG system is plug & play — it connects to a standard 13A socket. Most homeowners set it up in under an hour. No electrician required for basic installation. **Q: How long will the battery last?** A: With 6,000+ cycle life and one cycle per day, the battery is expected to last 16+ years. It comes with a 10-year manufacturer warranty. **Q: Can I add more batteries later?** A: Yes. The AEG system is modular — you can start with one 4.8 kWh unit and expand up to 9 units (43.2 kWh) at any time. **Q: Is the battery safe?** A: Yes. LiFePO4 is the safest lithium battery chemistry available. It has no risk of thermal runaway and includes a built-in Battery Management System. **Q: What happens during a power cut?** A: The AEG system can provide backup power during outages, keeping essential appliances running. **Q: What is the payback period?** A: Typically 2-4 years depending on your electricity tariff and usage patterns. --- ## Shipping & Returns - **Shipping**: Free UK mainland delivery on all orders - **Delivery Time**: 3-5 working days - **Returns**: 30-day returns policy - **Warranty**: 10-year manufacturer warranty on all AEG products --- ## Content Pages | Page | URL | Description | |------|-----|-------------| | Home | https://plug-insolar.co.uk/ | Main page with calculator, products, FAQs | | Home Battery Storage UK | https://plug-insolar.co.uk/home-battery-storage-uk | Comprehensive UK battery guide | | Economy 7 Battery Storage | https://plug-insolar.co.uk/economy-7-battery-storage | Economy 7 tariff optimisation | | Octopus Go Battery Storage | https://plug-insolar.co.uk/octopus-go-battery-storage | Octopus Go & Intelligent Octopus Go battery guide | | Plug & Play Battery Storage | https://plug-insolar.co.uk/plug-and-play-battery-storage | DIY plug & play installation guide | | Solar Battery Retrofit | https://plug-insolar.co.uk/solar-battery-retrofit | Adding batteries to solar | | Blog | https://plug-insolar.co.uk/blog | Articles and guides | | Best Home Battery UK 2026 | https://plug-insolar.co.uk/blog/best-home-battery-uk-2026 | Complete buyer's guide for 2026 | | Is Battery Storage Worth It? | https://plug-insolar.co.uk/blog/is-home-battery-storage-worth-it-uk | Costs & savings breakdown | | LFP vs NMC Batteries | https://plug-insolar.co.uk/blog/lfp-vs-nmc-batteries | Battery chemistry comparison | | How Much Can a Battery Save? | https://plug-insolar.co.uk/blog/how-much-can-home-battery-save | Annual savings by tariff | | How Much Can a Battery Save? | https://plug-insolar.co.uk/blog/how-much-can-home-battery-save | Annual savings by tariff | | AC vs DC Coupled Batteries | https://plug-insolar.co.uk/blog/ac-coupled-vs-dc-coupled-batteries | Coupling types explained | | Privacy Policy | https://plug-insolar.co.uk/privacy | Privacy information | | Terms & Conditions | https://plug-insolar.co.uk/terms | Terms of service | | Shipping Policy | https://plug-insolar.co.uk/shipping | Delivery information | | Returns Policy | https://plug-insolar.co.uk/returns | Returns and refunds |
