Britain’s Most Powerful Home Battery – Simply Better
The Tesla Powerwall 3 is the most advanced home battery available in the UK. It’s twice as powerful as the previous generation, which means it can run your entire home – not just a few lights and the fridge.
What Makes Powerwall 3 Special:
Everything Included in One Unit
Previous battery systems needed a separate solar inverter box costing £2,000-4,000 extra. The Powerwall 3 has everything built in, saving you money and space. It’s simpler, neater, and more efficient – like having an all-in-one printer instead of separate scanner, copier, and printer.
Works Brilliantly in British Weather
Designed to capture solar energy even on cloudy days. The system can handle much more solar panel capacity than the battery size, which means it charges effectively even when it’s overcast. Think of it as having a wide funnel collecting rainwater – you capture more even in a drizzle.
Runs Your Whole Home During Power Cuts
Unlike older batteries that struggled with high-power appliances, the Powerwall 3 can run everything at once – your electric shower, oven, heat pump, and kettle all working together. No more choosing which appliances to switch off during a power cut.
Safer, Longer-Lasting Battery
The Powerwall 3 uses Lithium Iron Phosphate technology – the same safer chemistry found in modern electric buses. It’s more stable, lasts longer (typically 15-20 years), and maintains its capacity better than older battery types. After 10 years, it’ll still hold 80-90% of its original charge.
Automatic Storm Protection
When the Met Office forecasts severe weather that might cause power cuts, your Powerwall 3 automatically charges itself to full and alerts you. You don’t need to do anything – it prepares itself and keeps you protected.

Solar battery storage explained
How Powerwall 3 Works
The Tesla Powerwall 3 is a fully integrated solar and battery system that stores energy for use when you need it most.
During the Day:
Your solar panels generate electricity. The Powerwall 3’s integrated inverter powers your home first, then charges the battery with any excess energy. When your battery is full, remaining surplus exports to the grid for SEG payments.
During the Evening:
As the sun sets, your stored solar energy automatically powers your home. The intelligent system learns your usage patterns and reserves enough energy for overnight needs. On time-of-use tariffs, the system strategically exports during peak pricing periods to maximise earnings.
During Power Cuts:
The Backup Gateway detects grid failure within milliseconds and seamlessly transitions your home to battery power. You won’t even notice the lights flicker. Essential circuits remain powered for hours or even days, depending on your usage and solar generation.
Smart App Control:
The Tesla app provides real-time monitoring from anywhere. Watch energy flows between solar, battery, grid, and home consumption. Review daily, weekly, and monthly performance. Adjust operating modes and backup reserves. Receive notifications about power outages, system updates, and Storm Watch activations.
FAQs
How much does a Tesla Powerwall 3 cost to install?
Installation costs vary based on your property configuration and existing solar system. Typical complete installations include the Powerwall 3 unit, Backup Gateway 2, installation labour, and commissioning. With the 0% VAT scheme, you save approximately £1,500 on this investment until March 2027. We provide detailed quotes within 48 hours of your enquiry.
Can I retrofit a Powerwall 3 to my existing solar panels?
Yes. The Powerwall 3 works with existing solar installations. If you have a working solar inverter, it can be AC-coupled to your system. Alternatively, we can replace your existing inverter and connect your solar panels directly to the Powerwall 3’s integrated DC inputs for improved efficiency. We’ll assess your current setup and recommend the most cost-effective approach.
What happens during a power cut?
The Backup Gateway 2 detects grid failure within 0.2 seconds and seamlessly switches your home to battery power. You’ll experience essentially no interruption – lights stay on, fridges keep running, and Wi-Fi remains connected. The system can power your home for several hours to multiple days depending on your energy consumption and available solar generation.
How many Powerwall 3 units do I need?
Most UK homes operate effectively with a single Powerwall 3 and its 13.5kWh capacity. Larger homes or properties with high evening consumption may benefit from expansion packs (adding 13.5kWh each, up to three per Powerwall 3) or multiple Powerwall 3 units. We analyse your energy bills and usage patterns to recommend the right system size for your needs.
Does it work on cloudy days?
Yes. British weather is rarely completely dark – even overcast days generate usable solar energy. The Powerwall 3’s oversizing capability (supporting up to 20kW solar input to charge a 5kW battery) means your system captures available light efficiently. On heavily overcast or winter days, the battery can charge from cheap overnight grid electricity on time-of-use tariffs, ensuring you always have stored energy available.
What's the expected lifespan?
Tesla guarantees 70% minimum capacity retention after 10 years with unlimited charge-discharge cycles. In practice, the Lithium Iron Phosphate chemistry typically retains 80-90% capacity after 10 years. Expected operational lifespan extends to 15-20 years with proper maintenance, delivering decades of energy savings and backup protection.
Can I charge from off-peak electricity?
Absolutely. This is one of the Powerwall 3’s most valuable features. On time-of-use tariffs like Octopus Intelligent Flux, the system automatically charges from the grid during off-peak periods when rates are lowest, then uses this stored energy during expensive peak periods. This strategy works even without solar panels, though combining both maximises savings.
Do I need planning permission?
Generally not. The Powerwall 3 falls under permitted development rights in most UK properties, requiring no planning permission for standard ground-floor or external wall installations. Listed buildings, conservation areas, or flats may require permissions. We handle all necessary approvals as part of our installation service.
What's included in the installation?
Our complete installation includes the Powerwall 3 unit, Backup Gateway 2, all required electrical components and mounting hardware, G99 DNO application and approval, MCS certification for SEG qualification, full system commissioning, and training on the Tesla app. We also provide 10-year workmanship warranty coverage and ongoing support.
How do I qualify for the Smart Export Guarantee?
Your installation must be MCS-certified (which all our installations are), you need a compatible smart meter with half-hourly export readings, and you must obtain an export MPAN from your Distribution Network Operator. We guide you through all requirements and handle the technical aspects to ensure you can claim SEG payments from day one.
What happens if I move home?
The Powerwall 3 can be uninstalled and reinstalled at your new property by Tesla Certified Installers. However, most homeowners find that leaving the system installed significantly increases property value and appeal to buyers. Modern home buyers actively seek properties with solar and battery systems, often adding £10,000-15,000 to sale value.
Can it be installed in a garage?
Yes, the Powerwall 3 suits garage installations. When installing near vehicles, we position the unit away from driving paths, ideally on side walls above vehicle bumper height. The IP67 rating provides excellent protection from dust and moisture. The unit operates quietly with fans typically below 50dB.
