How to spot a fake inverter or battery in Nigeria
Four checks you can run before you pay anyone, including us, and what the regulators have said about substandard imports.
Counterfeit and substandard solar equipment is a documented problem in Nigeria, not a rumour. Here are four checks you can run before you pay anyone, including us.
What the regulators have said
The Standards Organisation of Nigeria has repeatedly flagged unchecked substandard solar imports as a threat to consumer trust. In June 2026 REAN and SON moved jointly to tighten standards, citing that inferior products discourage investment and weaken confidence in the sector. The Rural Electrification Agency has commissioned a testing facility specifically to address panels, batteries and inverters that fail prematurely. And a consumer protection council investigation has been opened into dealers labelling panels with power ratings that do not correspond to actual output, with the petition warning of battery damage and explosion risk.
Check 1: the serial, not the sticker
A printed brand label proves nothing at all; labels are the cheapest part of a counterfeit. The serial number should resolve against the manufacturer's own register. Ask the vendor for it before you pay and check it independently. If they cannot produce one, or it does not resolve, walk away. We check serials free, whoever you bought from.
Check 2: weigh it
Compare the unit against the published spec sheet weight. Underweight almost always means undersized internals: thinner copper windings, smaller heat sinks, fewer or lower-grade cells. A 5kVA hybrid inverter that is three kilograms light is not a bargain, it is a different product in the same box.
Check 3: ask for usable capacity separately
A battery advertised as 10kWh should state nameplate capacity, usable capacity and depth of discharge as three separate numbers. Vendors inflate the headline by quoting nameplate on a chemistry that can only discharge half of it. On LiFePO4 you should see 90 percent or better; anything quoting 10kWh with 50 percent usable is lead-acid pricing dressed as lithium.
Check 4: ask for a flash test on the panel batch
Mislabelled panel ratings are the exact issue under investigation. A legitimate supplier can produce an IV curve or flash test report for the batch. This is a normal request and a vendor who is offended by it is telling you something.
One more. If an offer is far below every other quote you have received, it is not a discount. Compare quality and scope, not price alone.
