How are inverters rated?

Inverters are rated in terms of apparent power kVA. They may also have a real, or active, power rating in kW that is equal to or less than the kVA rating. It’s important to distinguish whether a numerical rating refers to kW or kVA, as we shall see in a later article. Power Triangles and the Apparent Power Circle

How does an inverter work?

An inverter often has a transformer as part of the circuit that attaches to an AC input and so is often an inductive load from the view of the power company. sources, such as solar power, provide not only electricity but can also be used to generate reactive power.

Why does my inverter report both'real' and 'apparent' power?

On the other hand, the inverter output stages need to be engineered for the "apparent" power that may be higher than the "real" power of the load. This is why inverters have both "real" power (W) and "apparent" power (VA) ratings and this is why your inverter reports both values.

What happens if a PV inverter runs under its rated output current?

Over 95% of the time a PV inverter is running below its rated output current when converting DC solar power to AC active power. The unused capacity of the inverter can then be put to use to produce reactive power.

What makes a good inverter generator?

An inverter generator tends to deliver power that’s “cleaner,” with more consistent voltage, which is reflected in the power quality test in our ratings. All of the recommended models have earned our highest score for power quality, while some of the conventional generators that we recommend score slightly below that.

How much power does an inverter need?

In your case, it could be something like 200W (allowing for ~90% inverter efficiency, normal for a modern inverter). On the other hand, the inverter output stages need to be engineered for the "apparent" power that may be higher than the "real" power of the load.
