If there's a -1 at the end of the Fronius model, it's split phase output with two hot output terminals. IG Plus 11.4-1 for instance. If there's a -3 at the end, it's a true 3-phase unit with three hot output terminals. IG Plus 11.4-3 for instance.
And Carl is correct, the larger Fronius units, particularly the 3-phase ones, have been pretty much backordered for the past couple months. Some end-of-year rush in Europe was the rumor we heard. Allow a month or two for delivery.

Fronius expects to catch up to demand by end of Q1 2010.

Looking through the manual I'm trying to determine whether each inverter in the line, between 3 and 12 kW, puts out three-phase power across all three poles, L1, L2 and L3 or whether all or some of these models put out power across just one or two poles like the SMA Sunny Boys. I'd appreciate any education on this. Thanks, marco Error! Filename not specified.
