Hello, everybody, this may be a long shot but I have been trying to research why a project isn't working.
The inverter outputs 277/480V 4 wire WYE. The building's power is 240 High Leg DELTA.
Inverter spec: https://www.solaredge.com/sites/def...erters_for_the_277_480V_grid_datasheet_na.pdf
After consulting several electricians, we placed a "480D -240D/120 CT" 75kva transformer in between.
Transformer spec: https://www.mgmtransformer.com/wp-content/uploads/2016/04/Bulletin10-DOE2016.pdf
Since then, the inverter in unable to function and constantly reads error codes.
I'm completely stumped. Perhaps the transformer is incompatible with the inverters WYE output?
Does anybody have any insight? Much appreciated!! Thank you for reading!
