myenergi Ireland: Zappi, Eddi & Libbi Review
myenergi is a British clean-energy brand best known for the zappi solar-aware EV charger and the eddi hot-water diverter, two of the most popular solar add-ons in Irish homes. They also make the libbi modular home battery and the harvi wireless sensor. Here's our independent review of the full myenergi range for Ireland, with specs, prices, warranties, and how the devices work together. They pair with any solar panel brand including Jinko, JA Solar, and Trina.
Quick Answer
myenergi is a UK brand whose zappi is the most popular solar-compatible EV charger in Ireland, thanks to its ECO+ mode that charges only from surplus solar. The eddi diverter sends excess solar to your immersion heater for free hot water. The libbi modular battery (5–20kWh, LFP, 10-year warranty) ties solar, EV charging and hot water together in one app. zappi from ~€1,000–€1,500 installed in Ireland; eddi from ~€400–€600.
Who Are myenergi?
myenergi is a British renewable-energy technology company founded in 2016 in Stallingborough, Lincolnshire. They design and manufacture their products in the UK. They don't make solar panels — instead they make the smart devices that sit alongside solar: EV chargers, hot-water diverters, home batteries, and the sensors and app that tie them together.
myenergi products are sold across Ireland and the UK through solar and EV installers. The zappi EV charger, in particular, is one of the most recommended chargers for homes with solar panels because of its built-in solar-tracking charge modes.

myenergi Zappi: The Solar EV Charger
The zappi is myenergi's flagship product and the most popular EV charger for solar homes in Ireland. Its standout feature is solar tracking: in ECO+ mode it charges your car using only surplus solar that would otherwise be exported, so you charge for free. See our full solar + EV charging guide for how this works in practice.
FAST mode
Charges at full speed (7kW) from the grid, exactly like a standard EV charger. Use it when you need the car ready quickly.
ECO mode
Charges using surplus solar topped up with grid power, keeping a steady minimum charge rate. Good balance of speed and savings.
ECO+ mode
Charges only from surplus solar. Pauses when a cloud passes and resumes when the sun returns. Completely free solar charging.

myenergi Zappi GLO: The Newer, Simpler Charger
The zappi GLO is myenergi's newest charger — a stripped-back, lower-cost version of the zappi. It drops the on-device screen in favour of app-only control, which keeps the price down. It keeps the smart features that matter: solar and battery integration, off-peak tariff charging, and RFID tap-to-charge.
| Feature | zappi GLO |
|---|---|
| Power | 7kW single-phase |
| Cable | 6.5m tethered Type 2 |
| Control | App only (no on-device screen) |
| Access control | RFID tap-to-charge, up to 126 users |
| Tariff | Octopus Intelligent and off-peak rates |
| Connectivity | WiFi, Bluetooth, local radio |
| Rating | IP65 (permanent outdoor), 6mA DC fault protection |
| Warranty | 3 years |
The GLO's up-to-126-user keycard support makes it a good fit for shared driveways, apartment parking, or small workplaces where several drivers share one charger.
myenergi Eddi: The Solar Hot-Water Diverter
The eddi is a solar power diverter: instead of exporting your surplus solar to the grid for a low export rate, it redirects it to your immersion heater to make free hot water. With Irish grid electricity at 35–45c/kWh and export at 15–24c/kWh, diverting surplus solar to hot water typically saves €200–€400 a year. It's often a cheaper way to lift self-consumption than a battery.
| Specification | eddi |
|---|---|
| Max heater load | 3.68kW |
| Min load | 100W |
| Standby draw | 3W |
| Phase | Single-phase (eddi+ for three-phase) |
| Compatible loads | Immersion, storage heaters, underfloor, electric heaters |
| Connectivity | WiFi, firmware updates, works with harvi |
| Install time | Under 1 hour |
| Warranty | 3 years |
For three-phase homes and commercial sites, the eddi+ offers 0–9kW variable output, up to two PT1000 temperature sensors, and built-in energy monitoring.
myenergi Libbi: The Modular Home Battery
The libbi is myenergi's home battery storage system. It's modular — you start with one 5kWh module and add more as your needs grow — and it has a hybrid inverter built in, so it can manage solar generation as well as storage. Because it's a myenergi product, it talks directly to your zappi and eddi to prioritise where surplus solar goes: the car, the hot water, or the battery.
| Specification | libbi |
|---|---|
| Capacity | 5kWh / 10kWh / 15kWh / 20kWh (5kWh modules) |
| Chemistry | Lithium Iron Phosphate (LFP) |
| Inverter | 3.68kW or 5kW hybrid (built in) |
| Phase | Single-phase |
| Backup | Prioritises essentials during a power cut |
| Integration | zappi, eddi, harvi — one app |
| Warranty | 10 years |
See our solar battery storage guide and battery brands comparison for how libbi compares to Tesla Powerwall, Huawei Luna and others.
myenergi Harvi: The Wireless Sensor
The harvi is a small, battery-free wireless sensor. A zappi or eddi needs to measure the electricity flowing in and out of your home (via a CT clamp on the meter tails) to know how much surplus solar is available. Normally that means running a signal wire back to the charger. The harvi reads the CT clamp and sends the data wirelessly instead — and it powers itself from the current it measures, so there are no batteries to replace.
It's an accessory for the myenergi ecosystem only (zappi and eddi), and it's useful where the consumer unit and the charger are far apart or a cable run would be awkward. Price from around €75. 3-year warranty.
myenergi Prices in Ireland
myenergi prices in Ireland vary by installer and whether the device is fitted on its own or as part of a wider solar install. Here are typical installed prices. The figures include fitting by a qualified electrician; buying the unit alone is cheaper.
| Product | What it is | Estimated price (installed) |
|---|---|---|
| zappi | 7kW solar EV charger | €1,000–€1,500 (€700–€1,200 after SEAI grant) |
| zappi GLO | 7kW app-controlled charger | €750–€1,100 |
| eddi | Solar hot-water diverter | €400–€600 |
| harvi | Wireless sensor (add-on) | €75–€120 |
| libbi | 5–20kWh modular battery | Quoted per system (varies with capacity) |
Prices are approximate and for guidance only. The SEAI EV home charger grant of up to €300 can reduce the net cost of a zappi. Always get a written quote from an installer. Compare options on our EV chargers guide.
The myenergi App
The myenergi app (iOS and Android) is the single control point for every myenergi device in your home. One login manages the zappi, eddi, libbi and harvi together, so you set priorities once and the system decides where surplus solar goes.
What you can see
- • Real-time solar generation and home use
- • EV charging session status and history
- • Hot-water diversion (eddi) and battery level (libbi)
- • Grid import/export in real time
- • Daily, weekly and monthly energy reports
What you can control
- • Switch zappi between FAST, ECO and ECO+ modes
- • Set charge schedules and off-peak tariff times
- • Set a boost timer on the eddi hot water
- • Set libbi charge/discharge priorities
- • Apply firmware updates over WiFi
myenergi Eddi vs Zappi: What's the Difference?
These are myenergi's two most popular products and they do different jobs with your surplus solar. Many Irish homes fit both: the eddi heats the water first, then the zappi charges the car with whatever is left over.
| Feature | zappi | eddi |
|---|---|---|
| Purpose | Charge an electric car | Heat hot water |
| Uses surplus solar | Yes (ECO+ mode) | Yes (its main job) |
| Output | 7kW / 22kW to the car | Up to 3.68kW to the immersion |
| You need it if | You have an EV | You have an immersion / hot-water tank |
| Typical price (installed) | €1,000–€1,500 | €400–€600 |
| Warranty | 3 years | 3 years |
Verdict: They are complementary, not competing. If you have an EV, the zappi pays back fastest. If you have an immersion heater and no EV, the eddi is the cheaper way to soak up surplus solar. With both fitted, the myenergi app coordinates them so the cheapest use of your spare solar always comes first.
