I have a client with a 240/480 single phase service with several transformers to step down to 120/240 at different points on the property. The property is very large and due to the distances they wanted to use the 240/480 with a transformer at each point of consumption. I will be installing solar and was thinking of just feeding his 120/240 panels with the inverter output. In some cases the energy would flow through two transformers before being consumed. Does anyone have any comments on this? What sort of losses should be anticipated at each transformer? Are there any transformer related issues that I should be careful of?
