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.</div><div style="font-size:12.8px;text-decoration-style:initial;text-decoration-color:initial"><br></div><div style="font-size:12.8px;text-decoration-style:initial;text-decoration-color:initial">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?</div><div style="font-size:12.8px;text-decoration-style:initial;text-decoration-color:initial"><br></div><div style="font-size:12.8px;text-decoration-style:initial;text-decoration-color:initial">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.</div><div style="font-size:12.8px;text-decoration-style:initial;text-decoration-color:initial"><br></div><div style="font-size:12.8px;text-decoration-style:initial;text-decoration-color:initial">Thanks for any input.</div>
