Cost of generators and inverters for home power in Nigeria
Nigeria faces persistent electricity challenges, with frequent power outages affecting homes and businesses.
As a result, many households rely on alternative power sources to ensure a steady electricity supply. Generators and inverters are the two most common options for backup power, each with its advantages and drawbacks.
This blog post provides an in-depth analysis of the cost of generators and inverters for home use in Nigeria.
We’ll compare their prices, running costs, and efficiency to help homeowners make informed decisions about which power backup solution suits their needs.
Understanding Generators and Inverters
Generators: How They Work
A generator is a device that converts mechanical energy into electrical energy. It typically runs on fuel, such as petrol, diesel, or gas. Generators are widely used in Nigeria due to their affordability and ability to power high-energy-consuming appliances like refrigerators, air conditioners, and pumps.
Inverters: How They Work
An inverter is an electronic device that converts direct current (DC) stored in batteries to alternating current (AC), which powers household appliances. Inverters are silent, environmentally friendly, and require less maintenance than generators. They are particularly useful for powering lights, fans, televisions, and other low-energy appliances.
Pros and Cons of Generators and Inverters
| Feature | Generators | Inverters |
|---|---|---|
| Upfront Cost | Lower | Higher |
| Running Cost | High (fuel consumption) | Lower (battery charging) |
| Noise Level | Noisy | Silent |
| Maintenance | Requires servicing | Minimal maintenance |
| Power Output | Can power heavy appliances | Limited by battery capacity |
| Environmental Impact | Emits fumes | Eco-friendly |
Both options have their merits, and the best choice depends on household power needs and budget.
Cost of Generators for Home Use in Nigeria
The cost of generators in Nigeria depends on factors such as brand, power output, and fuel type. Below is an estimated price range for different categories of home generators:
Small Generators (1–3 kVA)
- Suitable for powering light appliances such as bulbs, TVs, and fans.
- Examples: Elepaq 2.5 kVA, Tiger 1.2 kVA, Sumec Firman 2 kVA.
- Price range: ₦100,000 – ₦250,000.
Medium Generators (3.5–7.5 kVA)
- Can power multiple household appliances, including refrigerators and pumping machines.
- Examples: Honda 3.5 kVA, Sumec Firman 5.5 kVA, Lutian 7 kVA.
- Price range: ₦250,000 – ₦600,000.
Large Generators (8 kVA and Above)
- Ideal for homes that require constant and high electricity consumption.
- Examples: Mikano 10 kVA, Perkins 15 kVA, Hyundai 12 kVA.
- Price range: ₦1,000,000 – ₦5,000,000+.
Additional Costs of Running a Generator
- Fuel Consumption: Petrol generators consume about 1–2 liters per hour, while diesel generators are more fuel-efficient.
- Maintenance: Oil changes, spark plug replacements, and servicing cost around ₦5,000 – ₦30,000 per session.
- Noise Reduction: Soundproofing materials can add extra costs, ranging from ₦50,000 – ₦200,000.

Cost of Inverters for Home Use in Nigeria
The cost of inverters depends on their capacity, battery type, and solar compatibility. Below is an estimated price range:
Entry-Level Inverters (0.8–1.5 kVA)
- Suitable for powering lights, fans, and televisions.
- Examples: Luminous 1 kVA, Bluegate 1.5 kVA.
- Price range: ₦150,000 – ₦250,000 (excluding battery).
Mid-Range Inverters (2–3.5 kVA)
- Can support refrigerators and multiple appliances.
- Examples: Mercury 2.5 kVA, Sukam 3.5 kVA.
- Price range: ₦300,000 – ₦600,000 (excluding battery).
High-Capacity Inverters (5 kVA and Above)
- Suitable for large homes requiring uninterrupted power.
- Examples: Prag 5 kVA, Luminous 7.5 kVA.
- Price range: ₦700,000 – ₦2,000,000+ (excluding battery).
Battery and Solar Panel Costs
- Deep-cycle battery (200Ah): ₦150,000 – ₦300,000 each.
- Lithium-ion battery: ₦400,000 – ₦1,200,000 each.
- Solar panel (250W – 400W): ₦60,000 – ₦200,000 each.
- Installation cost: ₦50,000 – ₦150,000.
Generator vs. Inverter: Cost-Benefit Analysis
| Factor | Generator | Inverter |
|---|---|---|
| Initial Cost | Lower | Higher |
| Long-Term Cost | Higher (fuel, maintenance) | Lower (battery replacement) |
| Environmental Impact | High emissions | Eco-friendly |
| Power Duration | As long as fuel is available | Limited by battery capacity |
| Noise Level | High | Silent |
| Suitability | Best for heavy-duty appliances | Best for light to medium appliances |
Where to Buy Generators and Inverters in Nigeria
- Online Stores: Jumia, Konga, Kara, and Fouani.
- Physical Stores: Alaba International Market, Ariaria Market, and major electrical shops nationwide.
- Tips for Buying Genuine Products:
- Check for warranty and after-sales support.
- Buy from authorized dealers.
- Compare prices across different sellers.
Choosing the Best Option for Your Home
- For occasional power outages: A small generator or entry-level inverter may be sufficient.
- For regular outages with moderate power needs: A mid-range inverter is more cost-effective in the long run.
- For homes needing 24/7 power: A high-capacity inverter with solar backup is the best long-term investment.

Conclusion
Both generators and inverters provide essential backup power for Nigerian homes, but their costs and efficiency vary significantly.
While generators have a lower upfront cost, their running expenses make them expensive in the long term. In contrast, inverters require a higher initial investment but save money on fuel and maintenance over time.
Choosing the right option depends on your power needs, budget, and long-term financial planning. For homeowners looking for a quieter, eco-friendly, and cost-effective power backup, an inverter is a better choice.
However, for those needing a quick and affordable solution for heavy appliances, generators remain a viable option.
