AC grid connector labelling U, W & O? FoxESS H1 6.0E Hybrid
Hi folks. I’m installing a Single phase H1 6.0E inverter and looking at the AC grid connection plug, it has 3 terminals labelled with U, W and O respectively. This isn’t referenced in the manual and doesn’t seem to relate to a single or 3-phase connection.

The inverter was purchased some time ago now, so it out of the suppliers support time frame.

Can anyone please help clarify the correct connection or share a photo of an AC connector so I can see which are the L, N and PE pins please?

Many thanks
John.

If you put your question to Google Gemini it will explain the lettering correspondence (and the reason for it)
I won't reproduce the answer here since I don't have any expertise to be able to vouch for its accuracy.

Hi. Thanks for your reply. Sadly Gemini couldn’t confirm the connection as the letters used on the plug are similar (but not the same) as 3-phase nomenclature, so it confused the AI responses.

SOLUTION:
I managed to find this photo showing the internal side of the connector showing Red, Blue and green/yellow cables.

It therefore translates that:

W= Live
U = Neutral
0 = Earth (PE).

I have confirmed this work and no bad smoke was ejected as a result!

Hope this helps someone else out in the future.

Bw
John.
