Inverter Price in Nigeria: Avoid Hit-and-Run Vendors
The inverter price in Nigeria depends on two things, the inverter capacity (kVA) and the battery bank. As of June 2026, a Mercury hybrid inverter unit starts around ₦259,000 for the 1.5kVA Hybrid Solar Inverter, while a ready-to-install system that pairs the inverter with a battery bank starts around ₦1,191,000, and full solar-and-lithium bundles run from about ₦3.4 million into the millions for large setups. The cheapest inverter on the street can become the most expensive power decision you make. What protects your money is a genuine pure sine wave unit backed by a real warranty and an after-sales team that actually picks up the phone.
Buying an inverter in Nigeria is not easy, and finding the true, dependable inverter price is even harder. The market is full of vendors with very different motives. Some operations are strictly hit-and-run. They pull you in with a suspiciously low inverter price, then disappear the moment you need warranty support or a technician. When the system trips a month later, you are the one left in darkness, both literally and financially. Sound familiar?
At Mercury Direct we would rather show you the real numbers. This guide breaks down what actually drives the inverter price in Nigeria, gives you a verified price list pulled from our live storefront, and shows you how to spot a setup that will still be working in three or four years.
What a Cheap Inverter Price Really Costs You
A low price tag is tempting when NEPA has been off all day. But a cut-rate inverter price almost always comes with hidden compromises that cost more later.
- The wrong waveform for the wrong load. A modified sine wave inverter is perfectly fine for basic loads like lights, fans, TV, and charging when it is honestly sold and correctly sized. The trouble starts when a vendor passes a modified sine wave unit off as pure sine wave, or pushes it for sensitive appliances that need cleaner power, like some fridges, medical equipment, and delicate electronics. If you are not sure which one you are being offered, read our guide on pure sine wave versus modified sine wave inverters before you pay.
- No after-sales support. Hit-and-run vendors do not invest in technical teams. When a component fails, the calls go unanswered and you are left with an expensive box on the wall.
- A warranty on paper only. A warranty is only as strong as the company behind it. Unverified sellers promise multi-year cover but keep no spare parts and no engineers, so there is nobody to honour it.
Inverter and Battery Price in Nigeria: What Really Drives the Cost
A reliable inverter system is an investment in steadier power, not just a gadget. The inverter price you pay is built from two main blocks.
1. Inverter Capacity (kVA)
The capacity decides how many appliances you can run at once.
- Small systems (1kVA to 2.4kVA) suit lights, fans, TV, decoder, and phone or laptop charging.
- Medium systems (3.5kVA to 5.5kVA) can take on pumps, washing machines, deep freezers, and, with the right battery bank, an inverter-type AC.
- Large systems (8kVA and above) are built for bigger homes, estates, and businesses running heavier loads.
Not sure which size fits your home? Our guide on how to size an inverter for your home walks through it step by step.
2. Battery Technology
Batteries are usually the largest single part of your setup cost, so this is where the money really sits.
- Tubular and GEL batteries cost less upfront and give reliable service. Tubular handles deep, regular cycling well, which suits Nigerian backup duty.
- Lithium (LiFePO4) batteries cost more at purchase but can last up to about 10 years, charge faster, and need very little maintenance, so they often work out cheaper over the years. They also include a battery management system (BMS) for safety.
A Typical Lagos Home Essentials Load
Before you pick a size, it helps to see what a modest home actually draws. Here is a common essentials list.
| Appliance | Watts each | Qty | Total watts |
|---|---|---|---|
| LED bulbs | 10 W | 6 | 60 W |
| Standing or ceiling fans | 70 W | 3 | 210 W |
| LED TV plus decoder | 130 W | 1 | 130 W |
| Phone and laptop charging | 100 W | 1 | 100 W |
| Small fridge (running) | 150 W | 1 | 150 W |
| Approximate essentials load | ≈ 650 W |
A 1.5kVA to 2.4kVA system handles this comfortably. The fridge surge on startup is why we size with headroom rather than running an inverter at its absolute limit.

These figures are read off the live Mercury Direct storefront. Prices in Nigeria move with FX and import costs, so always confirm the current figure on the product page before you order.
Popular Hybrid Inverters (Unit Only)
If you already have a battery bank and just want a strong, intelligent hybrid inverter with a built-in MPPT solar charge controller, these are the standard unit rates.
| Inverter | Price (June 2026) | Best for |
|---|---|---|
| Mercury 1.5kVA Hybrid Solar MPPT | ₦259,000 | Lights, fans, TV, charging |
| Mercury 2.4kVA Hybrid Solar MPPT | ₦325,000 | Essentials plus a small fridge |
| Mercury 3.5kVA Hybrid Solar MPPT | ₦335,000 | Heavier loads; minimum size for any inverter-type AC, subject to battery bank and solar support |
| Mercury 5kVA Hybrid Solar MPPT | ₦595,000 (sale) | Pumps, freezers, larger homes |
These are unit prices, not backup-time promises. The inverter decides what you can run at once. The battery bank decides how long it lasts. That is why we always ask for your load list before recommending a system.
Deep Cycle Backup Batteries
A good inverter needs a strong heartbeat. These deep cycle options are built for heavy charging cycles and the Nigerian climate.
| Battery | Price (June 2026) |
|---|---|
| Mercury 65Ah / 12V | ₦159,000 |
| Mercury 100Ah / 12V GEL | ₦240,000 |
| Mercury Elite 220Ah Tall Tubular | ₦295,000 |
| Mercury 200Ah GEL Deep Cycle | ₦383,000 |

Generator Versus Inverter: The Real Running Cost
The sticker price is only half the story. The running cost is where a generator quietly drains your pocket. As of June 2026, petrol in Nigeria commonly ranges from about ₦1,100 to ₦1,400 per litre depending on your location and station, while diesel sits around ₦1,500 to ₦1,750 or more across different channels. Fuel prices move quickly, so your local pump price may differ from week to week, but the direction is clear: every extra hour on generator is becoming more expensive. The figures below use a mid-range petrol price of ₦1,300 per litre as a worked example.
| Cost factor | Petrol generator (≈ 2.5kVA) | Mercury inverter |
|---|---|---|
| Fuel, per day (8 hours, ≈ 1 litre/hour) | ≈ 8 litres at ≈ ₦1,300 = ≈ ₦10,400 | ₦0 petrol |
| Fuel, per month | ≈ ₦312,000 | ₦0 petrol (charges from NEPA or solar) |
| Servicing | Regular oil, plugs, and repairs | Minimal; no engine, no moving parts to wear |
| Noise and fumes | Loud, fumes, carbon-monoxide risk | Silent, no fumes |
| Lifespan under hard use | A few years | Inverter several years; lithium up to about 10 years |
One honest caveat. The inverter still needs to be charged from NEPA, solar, or another source, so it is not free power. Charging from the grid on a Band A feeder costs around ₦209.50 per kWh or higher depending on your DisCo, feeder classification, and the current tariff order. What the inverter removes is the daily petrol or diesel burn that makes generator backup so punishing, and pairing it with solar shrinks the charging cost further. You can sanity-check your own numbers with our battery backup time calculator.
How to Size Your Battery Bank
Runtime depends on your battery bank and your load, not just the inverter rating. The working formula is:
Backup hours = (Voltage × Amp-hours × Depth of Discharge × Inverter efficiency) ÷ Load watts
Take two Mercury Elite 220Ah tubular batteries wired in series. Series wiring doubles the voltage and keeps the amp-hours the same, so two 12V 220Ah batteries give a 24V 220Ah bank (not 440Ah). Using 80 percent depth of discharge for tubular and 85 percent inverter efficiency:
- Usable energy = 24 × 220 × 0.80 × 0.85 = about 3,590 watt-hours.
- On the ≈ 650W essentials load above: 3,590 ÷ 650 = about 5.5 hours.
- On a lighter 300W load (lights, fans, and charging only): 3,590 ÷ 300 = about 12 hours.
Want more hours? Add battery capacity or add solar to recharge during the day. Lithium banks let you discharge deeper (around 95 percent) for the same nameplate capacity, which is part of why they stretch further per kWh.

Inverter Price in Nigeria FAQ
How much does an inverter cost in Nigeria?
It depends on capacity and the battery bank. As of June 2026, a Mercury hybrid inverter unit starts around ₦259,000 for the 1.5kVA. A ready-to-install inverter-and-battery system starts around ₦1,191,000, while full solar-and-lithium bundles run from about ₦3.4 million up to several million naira for large setups. The inverter unit is only part of the price. Batteries are usually the largest single cost.
Is a cheap inverter worth buying?
A cheap inverter is not automatically bad, but it can become expensive if the vendor gives you the wrong waveform, the wrong capacity, weak batteries, or no after-sales support. A modified sine wave unit can be fine for basic loads when honestly sold and correctly sized. The bigger danger is a vendor presenting it as pure sine wave, or recommending it for appliances that need cleaner power, with no service team to call when something fails.
How long will my inverter battery last on backup?
Runtime depends on your battery bank size and your load, not just the inverter rating. As a worked example, two Mercury Elite 220Ah tubular batteries in series (24V, 220Ah) on a 2.4kVA system give roughly 5 to 6 hours on an essentials load of about 650W, and closer to 11 to 12 hours if you run only lights, fans, and phone charging. See the battery sizing section earlier in this guide for the full formula.
Lithium or tubular battery, which is better?
Tubular and GEL batteries cost less upfront and are a reliable choice for many homes. Lithium (LiFePO4) costs more at purchase but can last up to about 10 years, charges faster, and needs very little maintenance, so it often works out cheaper over its lifetime. The right choice depends on your budget and how heavily you cycle the bank each day.
Can I run my air conditioner on a Mercury inverter?
Use a 3.5kVA Mercury system or larger for any AC, and choose an inverter-type (variable-speed) AC, which draws far less than an older non-inverter unit. Whether it runs comfortably depends on the battery bank size and solar support, not the inverter capacity alone. A smaller 2.4kVA or 1.5kVA system is for lights, fans, TV, and charging, not air conditioning.
Does Mercury Direct deliver and install across Nigeria?
Yes. Mercury Direct offers same-day delivery within Lagos and delivery nationwide within 48 hours, with installation handled by in-house engineers. Standalone inverters and batteries carry a minimum 12-month warranty, and lithium complete systems carry a 5-year warranty, backed by a service centre stocked with genuine spare parts.
