Can't, that's why we need 2ea inverters with 50 kW on the roof. 25 kW on each of the two inverters.

How can this be done with a single inverter?

Our customer has enough roof space to for 58 kWp of modules, but we have to split the AC output into two separate services. So the first thing I've noticed is that there are not many inverters in the 30 kW range: Satcon PowerGate 30, Xantrex GT30 and by comparison a Sunny Tower with 6ea 6 kW SB inverters. We will be feeding 240 3P so the GT30 and ST will need transformers. So, I'm inclined to look more carefully into the PowerGate 30, first. I am looking for some feedback from folks who have recently installed 30 kW inverters. If this is contained in an archived thread, please direct me appropriately. - Peter Peter T.
