Importing generators from China

Few products move as reliably in Nigeria as generators, because the grid does not. That steady demand pulls a lot of importers into the category, and a lot of them lose money on it. The reason is almost never price. It is buying a unit that is the wrong size, the wrong frequency, or one that nobody can find parts for six months later. Generators are a specification-and-after-sales game, and the importers who treat them that way are the ones who reorder.

Size the unit to the real load

Oversizing wastes the customer's money on fuel; undersizing means the generator trips or burns out under load. Both come back to you. Before you choose a rating:

• Establish the actual load the unit will carry, including the surge that motors, pumps and compressors draw when they start. Starting load can be several times running load.
• Distinguish the running (continuous) rating from the maximum (standby) rating on the spec sheet. Buyers are often sold on the bigger number, which is the one the unit cannot sustain.
• Match the unit to how it will be used. A shop running a few hours a day at light load is a different machine from a factory running continuously.

Get voltage and frequency right

This is the single most common and most expensive mistake in the category. Nigeria runs on 230V at 50Hz. China is also a 50Hz country, so frequency is usually not a problem on units built for export, but you must never assume it. Some equipment is configured for 60Hz markets, and a 60Hz generator feeding 50Hz equipment will run motors fast, overheat and shorten the life of everything connected to it.

• Confirm 50Hz in writing on the spec sheet, not just in the chat.
• Confirm the output voltage and phase. Decide deliberately between single-phase for light and domestic loads and three-phase for industrial loads, and order accordingly.
• If you import a mixed container, check each model line. Do not assume the whole order shares one configuration.

On generators, frequency and rating are the deal. Almost every "the customer brought it back" story traces to a number that was never pinned down on paper.

Choose the fuel type deliberately

Petrol units are cheaper and suit small, intermittent loads. Diesel units cost more but are built for heavier, longer-running duty and are usually more economical to run hard. Match the fuel to the buyer:

• Petrol for small portable units and light domestic use.
• Diesel for larger continuous-duty sets and commercial buyers who run long hours.
• Confirm the fuel consumption figure at a realistic load, and whether the set is air-cooled or water-cooled, because that shapes its duty and its maintenance.

Think about the tank and the noise too. A unit with a small tank that suits a generator in a quiet test bay is a nuisance for a customer who needs it to run through the night without refuelling. Sound-attenuated canopies cost more but sell themselves in residential and office settings, where an open-frame set is simply too loud. These are not afterthoughts; they are part of matching the unit to the buyer who will actually live with it.

Build for a rough power supply

Generators in Nigeria face a harder life than the spec sheet assumes. The loads they feed are not always clean, the ambient temperature is high, and the unit may run far longer between services than the brochure imagines. Two things matter most:

• Automatic voltage regulation (AVR). A decent AVR keeps the output steady as the load swings, which protects both the generator and the equipment plugged into it. Confirm the unit has one and ask what it is.
• Derating for heat. A generator's rating assumes a reference temperature. In sustained Nigerian heat the usable output is lower than the headline figure. Build a margin into your sizing so the unit is not running flat out on the hottest afternoon.

A set that is honestly rated and properly regulated earns a reputation; one chosen on the brochure number alone earns returns.

Verify quality and the brand claim

Generator branding is heavily copied, and engine origin is often misrepresented. A unit sold as carrying a well-known engine may carry a clone.

• Be specific about the engine and alternator inside the set, not just the badge on the canopy.
• Ask for a video of the specific model running under load, and reference customers for the same unit.
• On a meaningful order, commission a pre-shipment inspection so the batch you pay the balance on matches the sample you approved.
• Apply the same supplier discipline you would on any equipment buy. The importing machinery guide and the broader verifying specifications checklist both apply here.

Plan parts and after-sales before you pay

A generator is only an asset while it runs. Plan the support before the money moves:

1. Order service kits and fast-wearing spares with the units: filters, plugs, belts, and the parts most likely to fail.
2. Confirm parts availability for this engine in future, and lead time.
3. Get the manuals, wiring diagrams and warranty terms in writing, and clarify what after-sales support the supplier gives and in what language.

Generators are heavy, so they ship by sea, and the staged payment that suits machinery suits them: a deposit to begin production, the balance once you have verified the units meet specification. Each payment settles in RMB on Alipay, and you do not need a Chinese account to send it. A trade facilitation service settles from your Naira at a rate locked on the day, with a receipt for each staged payment.

So size to the real load, confirm 50Hz and the voltage in writing, choose fuel by duty, verify the engine behind the badge, and order spares up front. When a deposit or balance falls due you can make a request to settle it on Alipay from Naira. The importer who specifies carefully sells generators for years; the one who chased the cheapest unit sells once.
