Re: [RE-wrenches] 480 single phase delta
If it's 240V single phase center tapped between two legs of a 480V delta transformer, then one of the 240V legs *is* technically a neutral. What you have is two 240V legs between two of three 480V phases. That said, if the service from the utility is this type of 480/240V "split-phase," which presumably is exclusively to run pumps, then you're probably going to have a hard time coming up with a good solution, and the utility will probably not appreciate the phase imbalance that would be introduced. On the other hand, if the load is constant and greater than the solar production, they may appreciate it, provided you can find a suitable inverter, which I don't know of for this type of service. If the service is actually 480V delta and they are providing 240V for the customer's convenience with a center tapped neutral, then obviously the 3-phase 480V is where you want to connect, but because you have 3 wires and not 4 this does not seem to be the case. See if the utility will supply the third hot 480V conductor and switch the service to 3-phase. They can leave the neutral in place to support the 240V loads.

Re: [RE-wrenches] 480 single phase delta
Hi Jay -Usually 408 delta will have 3 legs. See https://en.wikipedia.org/wiki/Three-phase_electric_powerUnlike Wye, the neutral is center tapped from the winding between two of the legs.The third is a hi leg or "stinger" leg that is 1.5 times the others voltage to neutral.Sounds like what you have is two of three legs with a center tapped neutral; the the hi leg is probably around somewhere on site. If you can find it then a 3-phase inverter will work. Otherwise, as mentioned you will need a transformer to get 240 across the legs you have. But 10kW of solar will unbalance the phases. Best to find that third leg and use a 3-phase inverter. I have used the Fronius IG Plus 11.4 for this with good results.
