Most facilities that have 480 volt service have either 120/208 or 120/240 volt
transformers to provide plug loads. You connect to one of these transformers.
If in the rare case you do not have any plug load transformer you provide a
120-480 or 120-277 volt transformer.
If your service is 2
Transformer? Just watch OCDP and the KVA.

Esteemed wrenches,
One of my students asked me today how you would (or if you could) connect a
120 volt outback inverter to a 277/480 volt 3 phase service. I said those
three little words that men find so hard to say, "I don't know". Help,
please.

Drake,
The sunny boy design tool assumes a max grid voltage of 240 (I have version 1.56 that allows you to select 250vAC as the max on screen #2), if your grid voltage exceeds the grid design voltage then the minimum mpp design voltage needs to increase along with it in order to maximize your kWh
Hello Wrenches,
Using the Sunny Design tool, I got a message saying the design was
conditionally compatible. The message said:
"In case of increased grid voltage, the operating point of the PV
generator may slightly deviate from its MPP if the module temperature
is high. This design can th
