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.

What is a power inverter?

The term "inverter" essentially refers to a circuit that converts the current from DC to AC (power inverter circuit), but it can also refer to a power inverter device used in home appliances, such as air conditioners and washing machines. Home appliances are not the only examples that benefit from inverter devices.

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?

What is the difference between kW and kVA?

kW (kilowatts) measures real power—what actually powers your appliances. kVA (kilovolt-amps) measures apparent power—the total power the inverter handles, including both useful and reactive power. The gap between the two can affect system performance and sizing.
