With Nigeria’s persistent power challenges, inverters have become an essential solution for homes, businesses, schools, hospitals, and estates. However, one of the most confusing aspects for buyers is inverter capacity. Many people ask questions like:
- What does 1kVA, 3kVA, or 10kVA really mean?
- Which inverter capacity is best for my home or business?
- How much does each inverter size cost in Nigeria?
- What happens if I choose the wrong capacity?
In this comprehensive guide, KSOP Global Limited explains everything you need to know about inverter capacities from 1kVA to 20kVA, including pricing, use cases, and expert recommendations-so you can make the right investment without wasting money or damaging your system.
What Does Inverter Capacity Mean?
Inverter capacity is measured in kVA (kilovolt-ampere). It represents the maximum electrical load the inverter can safely handle at a given time.
Simply put:
- Lower kVA = supports fewer appliances
- Higher kVA = supports more appliances and heavier equipment
In Nigeria, inverter systems must also handle:
- Frequent voltage fluctuations
- High ambient temperatures
- Long hours of usage
That’s why choosing the correct inverter capacity is critical for performance, durability, and safety.
Understanding kVA vs kW (Important!)
Many Nigerians confuse kVA with kW (kilowatt).
- kVA = apparent power
- kW = actual usable power
Most inverters operate at a power factor of 0.8.
So:
- 1kVA ≈ 800W
- 5kVA ≈ 4,000W
- 10kVA ≈ 8,000W
KSOP Global Limited always helps clients calculate real power needs before installation to avoid overload and system failure.
