The difference between constant power and rated power of inverter

4 FAQs about [The difference between constant power and rated power of inverter]

What is inverter kVA rating?

Inverter kVA rating measures the apparent power that an inverter can handle, expressed in kilovolt-amperes (kVA). It indicates the total capacity of electrical power that can be delivered by the inverter, including the power used effectively (apparent power or kW) and the power lost or not used directly (reactive power).

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 does rated power mean in a power inverter?

Power inverters come in many specifications, which usually include rated power and inverter peak power. Rated power is continuous output power, which refers to the power that the inverter can keep working for a long time.

Why should you choose a solar inverter rated in kW?

Inverters must handle peak solar input, battery charging, and load output—all at once. 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.
