480 volt stepup

[crossman gary]

My investigation further with the utility company and with the inverter maker somewhat matches your scenario. the only difference i have which is more of a personal preference is to go inverter->(delta-wye)->12kv ->delta-wye. My logic here is that I would like to wye ground the 12kv circuit.

I agree with your logic for the wye 12KV.

Now, any thoughts on the inverter being a seperately derived system? Need to attach the neutral to an electrode system? SBJ?

Apparently the inverter can adjust to whatever the translated circuit becomes after transformation and the utility does not care if we give them wye or delta.

That's good to hear.

Can you comment further on how large your PV system is?
