⚠️ The generator alone is not a complete backup system
To safely connect a generator to your home's circuits, you need a changeover switch wired by a registered electrician. Never connect a generator directly to a wall socket — this is dangerous and illegal. The full cost below is what a basic backup system actually costs.

Key highlights
🔇
53 dB at 25% load — remarkably quiet
Quieter than most conversations at a normal garden distance. ECO mode is whisper-quiet in typical home backup use
💻
Pure sine wave — safe for all electronics
Cleaner than the Irish grid — safe for laptops, medical devices, smart TV, smart home systems, EV onboard charger accessories
⛽
ECO mode — 8+ hours from 3.6L
Auto-throttle extends runtime dramatically at low load. One tank covers a typical Irish power cut from morning to bedtime

Option 2 — Generator + battery
🔋 Generator + battery
Battery provides silent overnight backup. Generator recharges battery and covers extended outages. No noise while battery is powering your home.
Complete energy independence. Solar charges battery daily. Generator as unlimited backup for extended grid outages. Near-zero fuel cost in normal conditions.
⚠️ Safety — read before installing: Never connect a generator without a proper transfer switch — this can electrocute ESB linesmen by back-feeding the grid. Always use a RECI or ECA registered electrician. Never run any generator indoors, in a garage, or near any opening — carbon monoxide is odourless and lethal. A 4-pole transfer switch must disconnect live, neutral and earth simultaneously.

❓ EU22i — frequently asked questions for Irish buyers
The Honda EU22i itself costs approximately €1,249. A complete basic backup system — including the generator, a 2-pole manual changeover switch (~€350), generator inlet socket and cable (~€100), and a RECI-registered electrician to install (~€450) — costs approximately €2,150 all-in. If you add a 5kWh battery and inverter-charger for silent overnight backup, the total rises to approximately €4,600. Combining with a 4kWp solar system and 10kWh battery brings the total to approximately €8,649 — with the SEAI Solar PV grant of €1,800 applicable to the solar and battery portion.
At 1.8kW rated output, the Honda EU22i can comfortably power essential household circuits simultaneously: fridge-freezer (~150W), all LED lighting (~50W), gas or oil boiler pump (~100W), smart TV and devices (~100W), broadband router (~20W), and phone charging (~100W) — a total comfort load of approximately 570–700W, well within the generator's 1.8kW rated output. In ECO mode, runtime extends to over 8 hours on a single 3.6L tank. Note: the EU22i cannot power an electric shower (7–11kW), electric hob, EV charger, or electric immersion simultaneously — these exceed its maximum 2.2kW output.
The Honda EU22i is one of the quietest petrol generators available in Ireland at 53 dB(A) at 25% load (measured at 7 metres) — quieter than a normal conversation. At full load the noise rises to 59 dB(A). In ECO mode at typical home backup loads (500–700W), it operates near the lower figure and is unobtrusive at garden distance. It remains significantly quieter than conventional open-frame generators, which typically produce 75–85 dB(A).
Petrol degrades in approximately 3–6 months in a generator's fuel system and carburettor, causing starting problems and fuel deposit build-up. For the Honda EU22i, best practice is: drain the carburettor fully if storing for more than 60 days; add a petrol fuel stabiliser (available from Honda dealers) if storing with fuel in the tank; and run the generator under load for 30 minutes monthly to keep the engine in condition. For backup applications where the generator may sit unused for months, a dual-fuel generator (such as the Hyundai HY9000LEK-2) with LPG capability is a more reliable long-term standby option — LPG has an indefinite shelf life.
No — this is extremely dangerous and illegal. Connecting a generator directly to a wall socket (known as a "suicide plug") creates a back-feed condition that can electrocute ESB linesmen working on apparently de-energised lines. It also violates Irish electrical regulations. The only safe and legal way to connect a generator to your home is via a transfer switch (manual or automatic), installed by a RECI or ECA registered electrician. The switch must be a 4-pole type that disconnects Live, Neutral and Earth simultaneously from the mains before connecting the generator. This is not optional — always use a registered electrician.
They serve different purposes and complement each other well. A generator provides unlimited backup as long as fuel is available — ideal for extended multi-day outages. Solar and battery storage is completely silent and automatic, requires no fuel management, and handles most Irish power cuts (which last under 4 hours) without any intervention. The combination — solar charges the battery daily; battery covers most outages silently; generator starts automatically for extended outages — is the most resilient energy setup available to Irish homes and businesses. See the Solar Panel Directory and Battery Directory for options.
You need a manual changeover switch wired by a registered electrician. This safely disconnects your home from the grid before connecting the generator — never connect a generator to your mains without one, as this creates a back-feed risk that can electrocute ESB workers. Budget approximately €350 for the switch and €450 for installation, bringing the total basic backup system to around €2,150.
Standard petrol generators do not qualify for SEAI grants. However, if you pair a generator with solar panels and battery storage, the solar and battery portion of your system qualifies for the SEAI Solar PV Home Grant of up to €1,800. See the Solar Panel Directory for full details.
A generator is a flexible short-term backup but needs fuel, produces noise and emissions, and requires manual starting. A solar + battery system provides silent, emission-free backup from stored solar energy and requires no action during a power cut. They complement each other very well — solar + battery covers most outages silently, while the generator provides unlimited backup when the battery is depleted during a long outage. Many Irish homeowners install both as a complete resilience solution.
Never run any generator indoors, in a garage, or near open windows or air vents — petrol generators emit carbon monoxide which is colourless, odourless and lethal. The EU22i must be operated outdoors with at least 1 metre clearance on all sides for ventilation. A purpose-built generator canopy is acceptable in rain, but the space must remain open on all sides to allow exhaust gases to disperse.
Petrol degrades in approximately 3–6 months, causing starting problems and fuel system deposits. Store in an approved metal can in a cool, ventilated outdoor area away from ignition sources. Add a petrol stabiliser (available from Honda dealers) if storing for longer than 3 months. If you need longer fuel storage, consider the Hyundai HY9000LEK-2 which supports LPG — LPG has an indefinite shelf life, making it much better for emergency standby applications.
