Which Generator Is Best for a Small Home?
For a small home with relatively basic power requirements, a 1–2.5kVA generator may be sufficient.
Possible loads can include selected combinations of:
Lights
Fans
Television
Decoder
Laptop
Phone chargers
Small electronics
A refrigerator may require additional capacity because its compressor draws extra power when starting.
Which Generator Is Best for a Large Home?
Larger households may require 6kVA, 7kVA, 8kVA or more, particularly when running several appliances simultaneously.
However, generator capacity should always be determined according to the actual load rather than the size of the house.
Can a Generator Power a Refrigerator?
Yes, provided the generator has sufficient running and starting capacity.
Refrigerators have compressors that can draw considerably more electricity when starting than during normal operation.
Always account for this startup surge when calculating the generator capacity you need.
Can a Generator Power an Air Conditioner?
Yes, but air conditioners can require substantial power.
The generator size required depends on:
AC horsepower
Inverter or non-inverter AC
Number of AC units
Starting surge
Other appliances running simultaneously
For example, you shouldn't assume that every 2.5kVA generator can comfortably operate an AC alongside other household appliances.
What Size Generator Should I Buy?
1kVA
Best for light backup requirements such as lights, fans and selected electronics.
2–3kVA
Better suited to small household loads with more appliances.
3–5kVA
Suitable for households requiring greater capacity and flexibility.
6–8kVA
Useful for larger homes, offices and small businesses.
10kVA+
Better suited to heavy residential or commercial loads.
The safest approach is to calculate the wattage of each appliance you plan to use simultaneously and allow additional capacity for startup surges.
What Should I Check Before Buying a Generator in Lagos?
Before purchasing, compare:
Rated capacity
Maximum capacity
Running watts
Starting watts
Fuel consumption
Fuel tank size
Runtime
Petrol engine specifications
Recoil start
Electric start
Remote start where available
Copper coil specification
Automatic Voltage Regulator
Noise level
Wheels and handles
Warranty
Spare-parts availability
After-sales support
Current selling price
Choosing a generator that is too small for your intended load can cause poor performance and potentially damage connected equipment.
