Wrenches,
We have a PV array situated about 900' from the POI (240V 1PH). We
initially spec'd (5) 11.4kW inverters and the combined output would be
238A. The wire size required for this current over that distance is cost
prohibitive.
A solution was to use a single 50kW 3 phase inverter at the array and then
convert it to 240V... somehow? Is anyone familiar with how to go about
doing this? My thought was to have a step down transformer at the POI and
pull off two legs to get 240V. Is this even a thing?
The other, more expensive option is to use a step up transformer at the
array and a step down at the POI to get us a smaller wire size.
Thanks for any input.
