myenergi vs GivEnergy vs Ohme vs Hypervolt: Which Ecosystem Wins?

In one sentence: myenergi wins on breadth for solar-first households; GivEnergy wins on single-brand storage depth; Ohme wins for Octopus Intelligent Go users who want the simplest, cheapest setup; and Hypervolt wins on design-led solar integration without battery complexity.

None of the four is the right answer for every household. The right pick depends on whether you have solar, whether you want a battery, which energy tariff you use, and whether you prioritise ecosystem depth or installation simplicity. This guide puts all four side by side on the dimensions that matter.

For context on how these ecosystems fit into the broader UK home energy picture, see our home energy ecosystem guide.

At-a-glance comparison table

Charger head-to-head

All four brands produce 7.4 kW single-phase smart chargers with Type 2 connectors, O-PEN fault protection, and OZEV chargepoint grant approval. The differences lie in power options, physical design, screen, and three-phase availability.

myenergi Zappi: Available in both 7.4 kW (single-phase) and 22 kW (three-phase) — the only one of the four with a three-phase option. The three-phase Zappi is relevant for households with a three-phase supply (relatively rare in UK residential properties but common in some new builds and rural properties). The Zappi is larger and more utilitarian in appearance than Hypervolt or Ohme.

GivEnergy EV charger: 7.4 kW single-phase. The smallest feature set of the four in charger-only terms, but it integrates directly with the GivEnergy portal and AIO battery, which is where its value lies.

Ohme Home Pro: 7.4 kW with an onboard LCD screen — the only charger in this group with a screen. The screen displays real-time charge rate, session cost, and schedule. The PIN lock adds physical access security. The ePod variant is screenless and more compact.

Hypervolt Home 3 Pro: 7.4 kW with a distinctive LED-ring interface. Consistently receives the highest marks for physical design and app UX in this group. Available tethered (5 m or 7.5 m) or untethered.

Verdict on charger hardware: Hypervolt leads on design; Ohme Home Pro leads on onboard information display; Zappi leads on power range (22 kW option). For most UK homeowners on a single-phase supply, the physical differences are secondary to software integration.

Solar integration head-to-head

Solar integration is where myenergi and Hypervolt pull ahead of Ohme, and where GivEnergy sits somewhere in between.

myenergi Zappi (Eco+ mode): The most sophisticated solar integration of the four. Eco+ modulates charging between 1.4 kW and 7.4 kW in real time, tracking your solar surplus second by second. Combined with Eddi (which diverts any surplus Zappi cannot absorb into your hot water cylinder), the myenergi system ensures that virtually no solar surplus is wasted. If you have solar and want to maximise self-consumption, Zappi is the strongest single charger option.

Hypervolt (three solar modes): Competitive with Zappi on solar mode capability. The three-mode system (Solar, Hybrid, Boost) covers the range of situations from a clear summer day (Solar mode) to a partial-cloud day (Hybrid mode) to an urgent charge needed regardless of cost (Boost). Hypervolt does not have a hot water diverter, so surplus that the car does not absorb goes to the grid rather than a second appliance.

GivEnergy (Solar Boost / Eco): Solar integration works via the portal for new GivEnergy full-stack installs. For households with a GivEnergy AIO battery, the inverter can manage the flow between solar, battery, and charger as a coordinated system — potentially more efficient than either Zappi or Hypervolt in a DC-coupled new build, because energy does not need to be converted to AC and back to DC for battery storage.

Ohme: Ohme has the weakest solar integration of the four. A CT clamp configuration allows it to reduce its charge rate during export, but it does not modulate dynamically in the way Zappi or Hypervolt do. For solar households, Ohme is not the optimal choice.

Battery and storage head-to-head

Only myenergi and GivEnergy offer battery products. If you want integrated charger and battery management under one brand and one app, the choice is between those two.

myenergi Libbi: Modular LFP battery, 5 to 20 kWh. AC-coupled, meaning it retrofits to any existing solar installation. Managed through the myenergi app alongside Zappi and Eddi. Relatively flexible: you start with 5 kWh and add modules later as budget allows. Integrated with the Eco+ priority chain.

GivEnergy AIO: Single 13.5 kWh LFP unit with integrated 6 kW inverter, IP65 outdoor-rated. DC-coupled (with Gen 3 inverter) for most efficient new installs. 12-year warranty. Larger storage in a single unit but no modular expansion path — you choose 13.5 kWh and that is your capacity.

Ohme and Hypervolt: No battery hardware. If you want a battery alongside these chargers, you source it separately (GivEnergy AIO, Tesla Powerwall, etc.) and manage it through a separate app. There is no unified controller between, for example, a Hypervolt charger and a GivEnergy battery.

Verdict on storage: myenergi Libbi for retrofit and modularity; GivEnergy AIO for single-unit new-build simplicity and longest warranty.

Tariff integration head-to-head

This is where Ohme and Hypervolt lead, and where GivEnergy sits furthest back.

Ohme (deepest Octopus IG integration): Ohme’s native Octopus Intelligent Go API is the most sophisticated in the market. It does not just schedule within the standard 23:30–05:30 window — it responds to extended cheap periods that Octopus grants for demand management, automatically continuing to charge at 7p beyond the window when grid conditions permit. No other charger in this comparison does this with the same reliability.

Hypervolt (native Octopus IG): Native Octopus IG integration with similar automatic window scheduling. Also supports OVO Charge Anytime natively. The Powerverse Raya layer can extend Hypervolt’s tariff optimisation to Octopus Agile half-hourly rate prediction.

myenergi (Octopus Flux native): Native integration with Octopus Intelligent Flux rather than IG. Flux is more suited to solar-plus-battery households because it rewards export as well as cheap overnight import. For pure EV charging cost, IG at 7p is a simpler win than Flux unless you also have solar or a battery.

GivEnergy (scheduler/open API): No native tariff API partnership. Manual scheduling in the GivEnergy Cloud portal for Flux, IG, or Agile. Advanced users can build Agile-responsive automation via the open GivEnergy API and Home Assistant. This is a gap for less technical users.

Price and running cost comparison

Charger-only purchase (hardware RRP, approximate 2026):

Full ecosystem (charger + battery, approximate installed cost 2026):

Running cost differences between tariff integrations are potentially larger than the price differences between chargers over a three-year period. At 10,000 miles per year and a 3.5 miles/kWh efficiency, you use approximately 2,857 kWh per year for EV charging. The difference between 7p (Octopus IG) and 27p (standard unit rate) is 57p per kWh — worth £1,630 per year. Getting the tariff right is at least as important as choosing the right charger.

Frequently Asked Questions

Which is better, myenergi or GivEnergy? myenergi is more modular and retrofit-friendly: its AC-coupled Libbi battery works alongside any existing solar, and Eddi adds hot water diversion as a second surplus use. GivEnergy offers deeper single-brand integration in a new DC-coupled install, with a larger battery unit (13.5 kWh vs myenergi’s 5 kWh starting capacity) and a 12-year warranty. For retrofits and households with existing solar, myenergi is typically the easier fit. For new solar-battery installs from scratch, GivEnergy offers strong single-brand efficiency.

Is Ohme or Hypervolt better for solar? Hypervolt, clearly. Ohme has limited solar mode capability via a CT clamp configuration; Hypervolt has three distinct solar modes (Solar, Hybrid, Boost) that modulate charging dynamically based on real-time surplus data. If you have solar panels, Hypervolt is the stronger choice between the two. For households where solar is a major priority, myenergi Zappi is the strongest option of all four.

Which ecosystem works best with Octopus? Ohme has the deepest Octopus Intelligent Go integration, extending your cheap window beyond the standard 23:30–05:30 period based on demand management signals. Hypervolt also has native Octopus IG integration with comparable automatic scheduling. myenergi integrates natively with Octopus Intelligent Flux, which is better suited to solar-plus-battery households. GivEnergy requires manual scheduling for any Octopus tariff.

Which is cheapest to buy? Ohme ePod and Hypervolt Home 3 Pro untethered are both approximately £899 at RRP — the most affordable two. The Ohme Home Pro and myenergi Zappi are around £999 to £1,099. GivEnergy’s charger is similarly priced to the Zappi. Full-ecosystem costs (with battery) range from approximately £10,000 to £15,000 depending on battery size and brand.

Can I mix brands — for example a Hypervolt charger with a GivEnergy battery? Yes. Both will function correctly and there is no technical incompatibility. However, they will not share a single app — you manage the Hypervolt charger through the Hypervolt app and the GivEnergy battery through the GivEnergy portal. There is no unified controller that automatically coordinates, for example, battery discharge timing with EV charging sessions. For single-app management, stick to one brand’s full stack.
