All three are quality brands, but they suit different priorities. Here is an honest comparison based on the systems we install across Central Scotland:
GivEnergy — Our most popular choice. The GivEnergy ecosystem is designed specifically for the UK market. Excellent app for monitoring and controlling your system, seamless integration with Octopus and other smart tariffs, and 5kWh units that can be stacked to your required capacity. Good value for money. EPS (backup power) available as an add-on.
Tesla Powerwall 3 — The premium option. 13.5kWh capacity in a single unit, built-in EPS as standard, sleek design, and the Tesla app. Best-in-class backup power — the switchover during a power cut is seamless. Higher price point but you get a lot of capacity and the most polished user experience. Especially popular with rural properties where backup power is a priority.
Solax — Great budget-friendly option, particularly as a hybrid inverter and battery package for new solar installations. Good performance, decent app, and competitive pricing. Best suited for customers who want a solid system without paying a premium for brand name.
Our recommendation:
- Best overall for UK homeowners: GivEnergy - Best for backup power and premium experience: Tesla Powerwall 3 - Best budget option for new solar + battery: Solax
We install all three and will recommend the best fit during your free survey.
