Generator Buying Guide 2025: Everything You Need to Know Before You Invest

Why Generators Matter
In Nigeria, where power supply can be unpredictable, a generator isn’t just a luxury—it’s a necessity. Whether for your home, office, or business, choosing the right generator ensures:
Reliable backup during outages
Protection for sensitive electronics
Smooth operation of appliances and equipment
This guide walks you through everything you need to know before buying.
Step 1: Know Why You Need a Generator
Ask yourself:
- Do you need backup for home essentials (lights, fans, fridge, TV)?
- Are you powering business tools (computers, printers, POS, freezers)?
- Do you run heavy-duty equipment (industrial machines, construction tools)?
👉 Your purpose determines the KVA rating you’ll need.
Step 2: Understand Generator Capacity (KVA/Wattage)
Generator Size | Ideal For |
---|---|
0.9KVA – 2.5KVA | Lights, fans, TV, laptops, small fridge |
3KVA – 6.5KVA | Freezers, multiple appliances, small business |
7KVA – 15KVA+ | Large homes, offices, supermarkets, heavy use |
💡 Tip: Calculate your total appliance wattage, then choose a generator rated 20–30% higher to avoid overload.
Step 3: Types of Generators
- Portable Generators: Lightweight, easy to move, ideal for light use
- Inverter Generators: Fuel-efficient, quiet, safe for electronics
- Standby Generators: Permanently installed, auto-start during outages
- Diesel Generators: Rugged, economical for large loads, but noisier
Step 4: Fuel Type & Consumption
Fuel Type | Pros & Cons |
---|---|
Petrol | Cheaper upfront, higher fuel use |
Diesel | Costlier upfront, better fuel efficiency |
Gas (LPG) | Cleaner fuel, less common in Nigeria |
👉 Consider fuel availability, efficiency, and long-term running costs.
Step 5: Noise Level
- Centrifugal & diesel models can be loud
- Look for “Low-Noise” or Inverter models if you live in residential areas
Step 6: Key Features to Look For
- AVR (Automatic Voltage Regulator): Protects appliances from voltage spikes
- Key Start (Electric Starter): Easier than rope pull
- Copper Coil: More durable than aluminum
- Fuel Tank Size: Bigger tank = longer runtime
- Wheels/Handle: Easier to move
Step 7: How to Spot Original vs Fake Generators
Checkpoint | What to Look For |
---|---|
Brand Reputation | Stick to trusted names: Elepaq, Firman, Honda, Sumec, Lutian |
Coil Type | Originals use 100% copper |
Packaging & Serial | Clear branding, manuals, serial numbers |
Weight Test | Fakes are often lighter |
Seller Reputation | Buy from trusted dealers like DISPASAL |
Step 8: Budget & Maintenance Costs
Don’t just focus on the price tag—consider:
- Fuel consumption
- Spare part availability
- Service costs (oil change, plug replacement, filter cleaning)
👉 Example prices in Nigeria (2025):
- Elepaq 10KVA: ₦300,000–₦530,000
- Sumec Firman 6KVA: ₦530,000–₦570,000
- Lutian 8.8KVA: ₦570,000–₦800,000
