Thanks, Bill.

I've got a 20k installation in California using SMA's. An local 
inspector (who was more familiar with LIPA) asked the CEO of Nextek if 
we were going to install an isolation transformer. 
I can explain to him that the SMA's have it built in, but I wanted to 
give him a little more scope, explaining where and when, and under what 
circumstances it is needed.
