For Addvalue, I would use an inductor rated for 2x what you want it to put out, ie 2x 16A = 32 Amp rated, for thermal safety.
I would use a microwave transformer 1uF capacitor to create a low pass filter.
Hate the price, so I would look around.

Here is another way to get a line reactor, use a microwave transformer core and wrap the wire size suitable for your current rating (*2 to be conservative). I have put a piece of cardboard between the E and the I of the transformer, to create a small air gap, this is what they do with inductors...

I have used 6mm2 building wire and got: 81uH at 10kHz frequency. You will probably be able to get wire of smaller overall diameter and get more turns.

I don't know how much this core will overheat with 8.8kHz or so carrier frequency, you can just try it.


Another thing, I was at a 1MW solar farm, here the inverter was connected to air core inductors. The solar farm output was connected to the 50 Hz power grid.
