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 are inverter specifications?

Specifications provide the values of operating parameters for a given inverter. Common specifications are discussed below. Some or all of the specifications usually appear on the inverter data sheet. Maximum AC output power This is the maximum power the inverter can supply to a load on a steady basis at a specified output voltage.

How much power does an inverter need?

It’s important to note what this means: In order for an inverter to put out the rated amount of power, it will need to have a power input that exceeds the output. For example, an inverter with a rated output power of 5,000 W and a peak efficiency of 95% requires an input power of 5,263 W to operate at full power.

What is the power factor of a solar inverter?

Most hybrid and solar inverters operate at a power factor between 0.8 and 1.0. The power factor directly impacts how much usable energy (kW) you can get from your inverter. 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.
