Describe a machine or appliance you find useful at home

The machine I find very useful at home is our inverter. Maybe not everybody know what it is. It is a box which is connected to two big batteries and also to some solar panels on our roof, and when the electricity from the government is cut, it gives power to the house automatically.

We have it since early 2024, so about two and half years. Before that we used a petrol generator, but fuel became so expensive that my father decided to switch.

We use it mainly for the fridge, the fans, the lights and the Wi-Fi. In Ibadan, where I live, sometimes we don't have light for ten or twelve hours, so without the inverter the food in the fridge will spoil. Also I am studying at the night for my exams, so I need to charge my laptop and use the internet.

It makes life much more easier. The generator was very noisy and it made a bad smoke, and my father had to queue in the petrol station every few days. Now everything is quiet and we don't think about it. My mother says it is the best thing we've ever bought, and I agree, especially in the hot season when you cannot sleep without a fan.

The appliance I'd struggle to live without is our inverter. It's not very glamorous, I admit: it's basically a metal box in the corner of our hallway, wired up to two heavy batteries and a row of solar panels on the roof, and whenever the mains supply goes off, it switches the house over to battery power within a second or two.

We've had it since early 2024, so roughly two and a half years now. Before that we relied on a petrol generator, but once fuel prices shot up, my father worked out that the inverter would pay itself within a couple of years, so he took the plunge.

It runs the essentials: the fridge, the ceiling fans, the lights and the Wi-Fi router. Power cuts in Ibadan can last ten or twelve hours, so it's what stops the food from going off, and since I'm revising for my final exams at the moment, it's also what keeps my laptop charged late at night.

The difference it's made is huge. The generator was deafening, it filled the yard with fumes, and my dad used to spend hours queuing for petrol every week. Now, when the power goes, we often don't even notice, apart from a little click from the hallway. My mum says it's the best thing we've ever bought, and in the hot season, when it's impossible to sleep without a fan, I'd find it hard to disagree with her.

I'd have to say our inverter, which probably sounds like an odd choice, but in our house it's practically a member of the family. For anyone who hasn't seen one, it's a grey box mounted on the hallway wall, hooked up to a pair of hefty batteries and a few solar panels on the roof, and the moment the grid goes down, it takes over without anyone having to lift a finger.

It's been with us since the beginning of 2024, so about two and a half years. Up until then we'd depended on a petrol generator, but when fuel prices more than doubled, my dad sat down with a calculator and concluded that it would pay for itself in under two years. He was right, as it turned out: it had paid for itself in about twenty months.

Day to day, it keeps the fridge, the fans, the lights and the router running. Outages in Ibadan can drag on for half a day, so it's the reason the food doesn't spoil, and with my finals coming up, it's also what lets me carry on studying past midnight without worrying about my laptop dying on me.

What it's really done, though, is take the stress out of power cuts. With the generator, every outage meant noise, fumes drifting in through the windows and my father queuing for fuel in the heat, sometimes for hours. These days the only sign the power's gone is a faint click in the hallway, and we just carry on. In the dry season, when the nights are stifling, that's no small thing.
