There is no way to insure the even sharing of the current between the three parallel diode strings, as there will be slight variation in junction voltage drops.

Agree with you mhamon.

Yes give some idea on it i am also waiting....

The info is good to know. I am downloading PVsyst 6.5.1 let see what will happen.

Did you find any?

Great work!

So what the IT specialists said?

Good to know about this info. Very useful...

I 'discovered' this a few months ago at a conference. I know a lot of people would like the ability to use their solar array in the event of a power outage. There are currently 3 'off-grid capable' inverters that can sync to a grid-tie inverter and trick it into thinking the grid is back. These inverters then couple with the grid-tie inverter and regulate it's output by sending excess energy to the battery or dump load. If the battery is full they increase frequency to 60.6Hz which won't effect anything being powered but will cause the grid-tie inverter to trip off-line. The AWESOME thing about AC coupling is that it can be used with virtually ANY grid-tie system... Micro-inverters, SMA, Fronius... doesn't matter.
