[RE-wrenches] AC Coupling different brands

[Drake]

I also saw that webinar. We had just coupled a Fronius 10K to a pair 
of Sunny Islands.  It seems to be working fine. It is a backup 
system, so we have only tested it.  SMA tech support assured me it 
would work before we bought the system.

Is the Outback wave form unique in any way, causing the Magnum have 
issues? Is the Sunny Island wave form cleaner?
