The Next Million Powerwall Rebate - you can get up to £750 back for your Tesla Powerwall installation: Find out more
The Tesla Powerwall 3 is one of the most advanced home battery systems available in the UK. Designed to store electricity from your solar panels or the grid, it allows homeowners to control how and when energy is used. By capturing surplus energy and releasing it whenever it’s needed, the Powerwall 3 can reduce electricity bills, provide backup power during outages, and optimise the way your home uses electricity.
At the heart of the Powerwall 3 is a rechargeable lithium-ion battery coupled with smart software that monitors energy use. The system stores electricity when it is abundant or cheaper: this could be from solar panels during daylight hours, or from off-peak nighttime tariffs. That stored electricity can then be used during periods of high demand, keeping your home powered efficiently without drawing from the electricity grid.
The Powerwall 3 has a usable storage capacity of 13.5 kilowatt hours, enough to supply a typical UK home for several hours. Its power output is designed to handle multiple appliances or heating systems simultaneously, with continuous output of seven kilowatts and peak output of eleven and a half kilowatts. Homes with higher energy needs can link multiple Powerwall 3 units together, creating a scalable solution for larger households or properties with high electricity consumption.
Electricity costs in the UK are often highest when demand is at its peak. The Powerwall 3 allows you to shift energy use to cheaper periods by storing electricity when it is available and using it when it would otherwise be expensive. This is particularly effective when combined with modern electric heating and hot water systems, such as our ELKATHERM® radiators and Sunamp hot water batteries. By heating your home and hot water using stored electricity, you can heat rooms when needed without relying on high-cost grid power. A full HeatElectric system - Tesla Powerwall 3, ELKATHERM® electric radiators and Sunamp heat battery – allows you to make the most of off-peak energy and free renewable energy, lowering your electricity bills while keeping your home comfortable.
The Powerwall 3 can be combined with a Gateway to become more than a money-saving device. The Gateway can provide backup power during outages, keeping essential systems running. In a power cut, the system can maintain lighting, refrigeration, heating, and hot water.
For homes with solar panels, the Powerwall ensures that most of the electricity you generate is used in the home rather than exported. Surplus energy is stored in the battery and can be used later in the day or overnight. This increases the value of your solar investment by ensuring the electricity you generate powers your home as efficiently as possible. Even in properties without solar panels, the Powerwall can charge from low-cost off-peak tariffs and discharge during the day, offering electricity bill savings.
The Powerwall is particularly valuable for homes with high electricity use, such as those with electric vehicles. It suits homeowners who want to reduce their reliance on the grid, maximise their self-consumption, and ensure comfort during power outages. Even without solar panels, the system can shift energy usage to cheaper periods, lowering bills and increasing efficiency. When paired with ELKATHERM® electric radiators and a Sunamp hot water battery, it becomes part of a fully electric, intelligent home energy system.
Tesla Powerwall 3 is a modern, smart solution that gives homeowners more control over their electricity. By storing energy when it is available and releasing it when needed, it can help reduce your electricity bills and your carbon footprint, while also giving peace of mind in case of power cuts. The Powerwall 3 is an investment that can make your home more comfortable, resilient, and cost-effective.
