Technical FAQs 4

What do kW and kVA mean in inverter specifications?

kW refers to the real or usable power output of an inverter. kVA represents the total power capacity it can carry, including power lost in phase difference (reactive power). For example, an inverter rated at 10 kVA with a power factor of 0.8 can only deliver 8 kW of real power.

How many kW can a 10 kVA inverter handle?

If your inverter has a power factor of 0.9, then a 10 kVA inverter will deliver only 9 kW of real output. This means the inverter can only handle 10.2 kW of actual load—not 12. Understanding this gap helps avoid overspending on capacity or overloading your system. How does this apply to solar and hybrid inverter systems?

What is the required inverter capacity?

If the total load of your devices is 800 watts, the required inverter capacity would be: \ [ \text {Inverter Capacity (VA)} = 800 \times 1.25 = 1000 \text { VA} \] Choosing the correct inverter capacity is critical for ensuring the stability of electrical systems in homes, offices, and industrial setups.

Why should I choose a kW or kVA rated inverter?

Choosing an inverter rated in kW (not just kVA) gives you a clearer view of real usable power. This prevents undersizing and keeps your solar-storage system running efficiently. How to choose between a kW and kVA-rated inverter?
