The term charging is normally associated with charging a battery or capacitor. If you have a transformer powering an inverter, the inverter is a load, but it is not charging.

Could you rephrase the question? I don't know what you mean by charging, and the concept of charging an inverter does not make any sense to me.

You certainly can NOT use a transformer with kilovolt output to power any inverter I'm familiar with.

Email me if you can explain better what you're asking and I'll take another look.

It's true that 'charging =/= load', but if you connect a charging circuit to a power source, then it is acting as a load.

The transformer isn't charging the inverter, it is supplying power to it, and will need to be sized to handle the inverter demand.

If somebody is talking about charging is not a load it is only a technical way to categorize. But charging is in fact a load for all practical purposes.

CHARGING A CAPACITOR IS CERTAINLY A LOAD. You might have seen a camera with a flash. the capacitor gets charged and it is not instantaneous. It takes a couple of secs to minutes.The battery drains because it charges the capacitor.
