Growatt inverter wiring in the US

[bpar8278]

I am wiring up a growatt 5000TL-X. The output of the inverter is three wire and 240 volts. So L1, N, PE. I take my 240 from the l1 and the N and ground the PE. I get an abnormal ground. How is this possible to even do without another wire? Is this inverter designed just for one leg at 240v a neutral and a ground for output? Am I missing something?

This is a European model.
230/240v single phase to neutral.

That makes more sense. The guy that sold it to me claims he has sold a bunch of these to the states and no problems.. So I have been scratching my head! Thank you

That also explains why the only countries it would let me select was Australia and new zeland.

You need an autotransformer that provides a center tapped neutral and ground to convert the unit into split phase output.

I'm not sure if that model isn't internally bonded.
I've never seen it used in the US.

DOh... I was thinking the ES
