p.p.s. Yes I was proving your fallacy by my sequitur . The fundamental construction does not matter except for cost reductions possible. I varied Lp over a 10:1 ratio but it is the differential reduced flux and resulting excess core margin that leads to size reductions possible, but optional. It is simply the orientation of windings, and inverted winding ratio 1-(10:1) vs (10-1):10 for n=10/9Isolated construction - so that one can easily change it from bucking to boosting - else it can only be one or the other
I think I used the word construction, apologies if not. A standard 230: 30 Tx ( with isolated sec per usual ) is very handy in this regard, as you can then have 200V or 260 V ac ....

p.s. the opposite of non-sequitur is I think just sequitur
All we want is that when the house solar panels are generating, or when the house battery is discharging, then we want to minimise the current flowing (exporting) to the grid. We want instead, as much of the current as possible to flow into the house loads.A GTI is by operation principle tied to the grid and tries to convert the available input power. Why would you want to throttle the output power of a solar inverter? Please clarify your use case.
Thankyou yes, i thought as much, with an autotransformer as described, the grid will look like a lower impedance than it is, so this would mean more export of electricity to the grid...wrong way round - as it's stepping up back to the mains, it will export more not less ...
Though anyway, from what you describe, then you would expect all grid tied inverters (for 220-240VAC) to have a low ratio step down transformer upstream of them, and i dont think most do?
it dependsif the neutral is lost, there is no return path, hence the voltage seen by the single phase GTI is zero
if the neutral is lost, there is no return path, hence the voltage seen by the single phase GTI is zero
