GivEnergy All-in-One Review
If you're adding battery storage to solar panels in the UK, the GivEnergy All-In-One is the default choice. Not because it's the only option — Tesla exists, Solis exists, SolarEdge exists — but because it consistently hits the right combination of price, functionality, and UK-specific features that most households actually need.
What "all-in-one" actually means
In the battery storage world, "all-in-one" means the inverter and battery are integrated into a single unit. The alternative is a hybrid inverter (a separate box on the wall) paired with a separate battery module. All-in-one systems are cleaner to install, take up less wall space, and have fewer potential points of failure. For most domestic installations, it's the right architecture.
GivEnergy's All-In-One combines a hybrid solar inverter with a lithium iron phosphate (LFP) battery in one enclosure. LFP chemistry matters: it's safer and longer-lasting than the NMC chemistry used in some competitors. GivEnergy typically quotes 6,000+ charge cycles — at one cycle per day, that's 16+ years of daily use before the battery reaches 80% of original capacity.
Capacity options and pricing
| Capacity | Typical installed price |
|---|---|
| 5.0 kWh | ~£3,000–£3,800 |
| 8.2 kWh | ~£3,800–£4,500 |
| 9.5 kWh | ~£4,000–£5,000 |
| 13.5 kWh | ~£5,000–£6,000 |
For most 3–4 bedroom UK homes with solar panels, the 8.2kWh or 9.5kWh option is the sweet spot. It's enough to store a meaningful proportion of your solar generation and charge overnight on a cheap tariff without paying for more capacity than you'll realistically use.
Time-of-use tariff integration
This is where GivEnergy genuinely earns its UK market position. The system integrates directly with Octopus Energy's smart tariffs — Flux, Agile, Intelligent — allowing the battery to charge automatically during cheap overnight periods and discharge during expensive peak hours. The GivEnergy app makes this straightforward to configure, and it works reliably.
If you're on Octopus Agile with rates that vary by half-hour slot, the GivEnergy system can respond to those price signals automatically. That's meaningful: it's the difference between a battery that just stores solar energy and one that actively optimises your electricity costs around grid pricing.
The app and monitoring
The GivEnergy app is genuinely good — clear energy flow visualisation, historical data, the ability to set charging schedules, and remote control. It's not perfect; some users report occasional connectivity glitches. But compared to the monitoring software shipped with some competitors, it's well ahead.
Modular expansion
You can add additional battery modules to the GivEnergy system after installation, up to 19.2kWh. If your budget is limited now but you want to expand later, you can start with 5kWh and add to it. Tesla's Powerwall 3 doesn't offer this kind of flexibility.
British company, UK support
GivEnergy is based in the UK — genuinely, not just incorporated here. Their support team is UK-based and has a reasonable reputation for responsiveness. For a product that needs firmware updates and occasional technical support, having support in your timezone and language matters.
Who should buy this
- Anyone adding battery storage to existing or new solar panels in the UK — this is the default recommendation.
- Anyone on or planning to join an Octopus smart tariff — the integration is excellent.
- Anyone who wants flexibility to add capacity later without replacing the system.
- Anyone comparing it to Tesla who is honest about what the price difference buys them.
Who should look elsewhere
- If backup power during grid outages is a hard requirement, the Tesla Powerwall 3's backup capability is more mature.
- If aesthetics matter significantly — a prominent wall location in a nice utility room — the Tesla looks better.
- If you specifically want the Tesla brand for resale purposes (debatable benefit), go for it.
For everyone else: this is the one. The UK's favourite solar battery for good reason. For a deeper dive into the storage decision, see our solar battery storage guide, or read our head-to-head GivEnergy vs Tesla Powerwall comparison.
