Battery Storage Solutions
Add a Tesla battery storage to your home to benefit from more affordable electricity all year round. Tesla Powerwall 3 batteries can be charged either when electricity is cheaper, such as overnight, or by using solar panels.
H2ecO has been leading the local Dorset renewable industry for 15 years. We have been installing battery storage devices to happy customers for nearly as long as that. We were among the very first group of installers certified to install the Powerwall 1 in the UK.
Thanks to our personable and professional installation service, we have excellent reviews from happy customers.

H2-eco currently offer three premium battery solutions:
- 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.
- 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.

How does Tesla Powerwall battery storage work?
Tesla Powerwall battery storage – powered by the Tesla Powerwall 3 – stores excess electricity generated by either your solar PV system during the day so that energy is available when you need it, or by using lower priced electricity at night to move to the next day.
This approach to energy storage provides:
- All Year Power: Your solar panels generate electricity during daylight hours, or charge your batteries when electricity costs are at their lowest.
- Storage: Excess energy is stored in the Tesla Powerwall battery instead of being sent back to the grid. This gives you power on demand.
- Backup: Power your entire home during grid outages and never lose power with a full-home energy backup.
- Smart energy management: The system manages when to charge and discharge based on usage patterns, time-of-use tariffs, and solar production, helping you to save money and reduce grid reliance.
Key benefits of Tesla storage batteries in the UK
- Cost savings: Excess energy generated from the solar panels can be used during off-peak grid times, lowering your electricity bills.
- Seamless integration with solar system: Powerwall 3 can function as a hybrid inverter, managing both new and existing photovoltaic (PV) systems.
- Scalability: The system allows expansion up to 54 kWh with DC expansion packs, accommodating varying energy storage needs.

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.
