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?

Hi Jeremy,
FYI: I heard that Fronius is the most sensitive of the GT inverters
and so the most difficult to "fool" or keep on in an AC coupled
system. That was from the Magnum AC Coupling webinar.
Blessings,

Hope everyone is enjoying their weekend!
I have a system where we have Installed a pair of XW inverters
along with a 10k Fronius inverter.
We have been told that we need to limit the PV watts to the lowest
XW inverter. We have XW capacity in excess of the array, so why
can't they entire array feed the system when the grid is down?
Of course tech support is tougher when you use different brand
names, but I'm sure this has been done in the field already.
Please contact me off list If you can help us out. The customers
electrician on this job has been trying hard to figure it out, but
I think he might be in too deep!
