690.9(D) states that if the AC Disconnect on the utility side of the XFMR is appropriately sized, then no Disconnect is needed
between the inverter and the XFMR, which in our case is a 480Y to 208D, 175KVA.
But what about if there are 2 inverters feeding 1 transformer, combining on the lugs of the transformer?
My interpretation is that the code still reads the same and no AC disconnects are needed.
Any thoughts appreciated and yes I know the AHJ is who I need to ask.
thanks.
