Hi Bill, Those SMA inverters can handle a max Isc of 18A. Check your module datasheet, but I would assume that you would be under this limit. I've had strings with an Imp of 11-12A and the inverter just adjusts where it is on the MPPT curve to keep the current to under 10A. So there is a little bit of clipping on high power days, but it works just fine.
