Hi Mac--
We've installed four Magnum 4048-Fronius AC coupled systems, ranging from the older Fronius IG through the later Fronius IG Plus with arc fault. One system had three Magnums, another two Magnums and two were single Magnums. We had a small glitch on the two Magnum system on one occasion that we haven't yet figured out and we don't yet have enough info to make a pronouncement. The grid dropped out on a cold, partly cloudy, sunny day with winds quickly moving the clouds past the modules. The Fronius IG Plus would not switch to the second stage after the clouds passed and the sun came out. We weren't there at the time and conditions are hard to replicate. Magnum tells us it's a Fronius issue and we are hoping to work with someone at Fronius to learn more.

Hello wrenches,
Has anyone had good success AC coupling with Fronius Inverters? If so, what equipment did you use? Was this with an IG or an IG Plus?
I have had quite a few people lately with Fronius Inverters that would like a backup solution and I'm not comfortable AC coupling these, but could potentially be persuaded.
Thanks
