Tesla Powerwall
Battery storage can introduce additional versatility to a Solar PV system, but is not always an essential component. The financial and operational case for having a battery will be quite bespoke to you and your energy consumption profile, so it is worth reviewing carefully rather than just accepting a “packaged” PV and battery system. Such recommendations are often made by sales people with targets to meet rather than a considered evaluation of what might be best for your circumstances.
That said, there can be additional benefits from having a battery beyond just capturing solar energy for use later when the sun has gone down. A variety of electricity supply tariffs now enable you to charge a battery during lower-rate periods and then use it when you would otherwise be importing at higher rates. This added value for battery storage is dependent on having access to such dual-rate tariffs, but at the current time can add significantly to the value of having a battery system.
A good battery system can also offer you a source of power for all or part of your house supply in the event of a power cut.
H2-eco currently offer three premium battery solutions: GivEnergy Hybrid and AC-coupled systems, The DC-coupled Home Battery from Solar Edge and the exceptional Tesla Powerwall 3
GivEnergy solutions can be part of a new PV installation with a hybrid inverter or can stand alone with their own battery inverter. Battery sizes of 5-13.5kWhours are available. Stand-alone systems are typically in the £5000-£8000 range for 9.5 to 13.5kWhours of storage.
The Solar Edge Energy Bank provides 9.7kWhours of DC-coupled battery storage for an installed cost of around £8000. This battery will only function as part of a Solar Edge PV system
The Tesla Powerwall 3 provides 13.5kWhours of AC-coupled battery storage with full-house back-up in the event of a grid outage for an installed cost of around £7,500. Powerwall 3 can also operate as a hybrid inverter to operate a new or existing PV system.
Batteries are currently zero-rated for VAT, whether installed as a stand-alone system, added to an existing PV system or installed with a new PV array.
Why Install a Tesla Powerwall 3
H2-eco are Tesla Certified Installers & Powerwall experts. We offer a premium installation, support, and advice service to help you make the best decisions for your home or business energy needs. Combining solar with a Powerwall will enable you to reduce your monthly electricity bills and become less dependent on the national grid for energy. Powerwall can work through power cuts and provide your home with energy security.
Powerwall 3 is a fully integrated solar and battery system designed to accelerate the world’s transition to sustainable energy. Powerwall 3 can store solar or grid energy for later use when the sun goes down or when the electricity prices are high; lowering electricity bills, reducing reliance on the grid, and power homes during a grid outage.
Once installed, customers can manage their home energy system using the Tesla App and customize system behaviour to meet their energy goals.
Technical Specifications for PowerWall 3
- Usable Capacity: 13.5kWhours, scaleable to 54kWhours with DC expansion packs
- Continuous power to your home: 3.68kW – 11.05kW depending on Grid Operator approval
- With Grid Operator approval continuous power to your home: up to 11.05kW
- Weight: 125kG
- Warranty: 10 years
- Dimensions: 1099mm x 609mm x 193mm
- Mounting: Wall or Floor Mounted, Inside or Outside.
Powerwall 3 can be installed as a stand-alone AC-coupled battery or can also be used to operate a PV system as well, retaining all the same power-management and grid back-up functionality. The built-in inverter output rating is able to be set in firmware between 3.68 and 11.04kW per unit. This makes it a uniquely flexible solution for utilising generation from up to 20kWp of solar panels and maximising the system output within any constraints set by the Grid Operator permission. Powerwall 3 has the ability to store 13.5 kWh of energy as standard. This storage capacity can be increased by adding up to 3 additional 13.5kWhour expansion packs, making a total of 54kWhours.
Powerwall 3 has active thermal management which enables it to perform whether located indoors or outside. A cast aluminium housing with weatherproof glass frontage and illuminated Tesla Logo creates a functional and stylish solution.

This video describes the experience of Robert, an early adopter of sustainable energy, who installed solar panels on his roof seven years ago.
He has recently added a Tesla Powerwall to further his solar energy use throughout the night.
Now the vast majority of electricity that his family uses at home comes from the sun.
