Question 1

What does a complete Honda EU22i backup system cost in Ireland in 2026?

Accepted Answer

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.

Question 2

What appliances can the Honda EU22i power during a blackout?

Accepted Answer

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.

Question 3

How loud is the Honda EU22i when running?

Accepted Answer

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).

Question 4

How long does petrol last in a stored Honda EU22i?

Accepted Answer

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.

Question 5

Can I connect a generator directly to my home's mains socket?

Accepted Answer

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.

Question 6

Is a generator better than solar and battery backup for an Irish home?

Accepted Answer

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.

Question 7

What do I need besides the generator to back up my home?

Accepted Answer

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.

Question 8

Can I get a grant for a home generator in Ireland?

Accepted Answer

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.

Question 9

How does a generator compare to solar + battery for backup?

Accepted Answer

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.

Question 10

Is the Honda EU22i safe to use near my home?

Accepted Answer

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.

Question 11

How do I store petrol for my generator?

Accepted Answer

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.
