Generator Size Calculator Nigeria — What KVA Generator Do You Need?

Use this free calculator to find out exactly what size Mikano generator you need for your home, office, church, hospital, or factory in Nigeria. Select your appliances, enter quantities, and get an instant KVA recommendation with current prices.

The generator size you need in Nigeria depends on the total wattage of all appliances you want to run at the same time. Add up your appliance wattages, multiply by 1.25 for a safety buffer, then divide by 800 to get the minimum KVA required. A typical 3 bedroom home needs a 15KVA to 20KVA generator. A small office needs 20KVA to 40KVA. A hospital or factory needs 100KVA and above.

How to Calculate Generator Size in Nigeria — The Formula

Here is the exact method engineers use, simplified for everyone.

Step 1 — List all appliances you want to run at the same time

Write down every appliance you need to power simultaneously during a normal day. Do not include appliances you will rarely use at the same time.

Step 2 — Find the wattage of each appliance

Every electrical appliance has a wattage rating printed on a label at the back or bottom. Air conditioners are the biggest consumers — a 1.5hp AC uses approximately 1,200 watts. A refrigerator uses around 300 watts. A ceiling fan uses about 75 watts.

Step 3 — Add up the total wattage

Add the wattage of every appliance together. Example: 2 air conditioners (2,400W) + 1 refrigerator (300W) + 4 ceiling fans (300W) + 10 LED bulbs (150W) + 2 televisions (300W) = 3,450 watts total load.

Step 4 — Add the 25% safety buffer

Multiply your total by 1.25. Running a generator at 100% capacity causes overheating and shortens engine life significantly. Example: 3,450W × 1.25 = 4,312 watts minimum required.

Step 5 — Convert watts to KVA

Divide by 1,000 to get kilowatts, then divide by 0.8 (power factor). Example: 4,312 ÷ 1,000 = 4.3kW ÷ 0.8 = 5.4 KVA minimum. The nearest Mikano generator above this is the 15KVA.

Frequently Asked Questions — Generator Sizes in Nigeria

How do I calculate what generator size I need in Nigeria?
Add up the wattage of all appliances you want to run at the same time. Multiply by 1.25 for a safety buffer. Divide by 1,000 to get kilowatts, then divide by 0.8 to convert to KVA. Use the free calculator on this page to do it automatically in seconds.
What size generator do I need for a 3 bedroom house in Nigeria?
A typical 3 bedroom house in Nigeria with 2 air conditioners, a refrigerator, television, fans, and lighting needs between 5,000 and 10,000 watts. A Mikano 20KVA soundproof generator starting from ₦8,365,000 is usually the right size. If you have a borehole pump or more than 2 ACs, consider a 30KVA unit.
What size generator does a small office need in Nigeria?
A small office with 5 to 10 computers, 1 or 2 air conditioners, lighting, and a printer typically needs between 5,000 and 12,000 watts. A Mikano 20KVA or 30KVA generator starting from ₦8,365,000 is usually the right fit.
What size generator does a hospital need in Nigeria?
A small clinic needs at least a 20KVA to 40KVA generator. A medium hospital typically needs 100KVA to 200KVA. A large hospital may need 200KVA to 500KVA. Contact Links Energies on WhatsApp for a custom recommendation.
What size generator does a church need in Nigeria?
A small fellowship needs a 15KVA to 20KVA generator. A medium church with air conditioners and full sound system needs 40KVA to 80KVA. A large auditorium seating over 1,000 people may need 100KVA to 200KVA.
Is KVA the same as KW for generators?
No. KW is the actual power your appliances consume. KVA is the apparent power rating of the generator. To convert KW to KVA, divide by 0.8. So a 16KW load requires a 20KVA generator.
What happens if my generator is too small for my appliances?
An undersized generator runs at or above full capacity constantly. This causes overheating, dramatically increases fuel consumption, shortens the engine lifespan, and can cause sudden shutdown or permanent engine damage.
How much does a Mikano generator cost in Nigeria?
Mikano generator prices in Nigeria range from ₦6,024,000 (open type 15KVA) to ₦117,060,000 (soundproof 750KVA). The soundproof 20KVA starts at ₦8,365,000, the 100KVA at ₦16,400,000, and the 200KVA at ₦27,618,000. All prices are VAT inclusive. Contact Links Energies on WhatsApp for the current best price.
