[RE-wrenches] Fronius Symo 10.0-3 208V 3 phase WYE without neutral

[James Jarvis]

Hi Group,

We have an install with four Fronius Symo 10.0-3 inverters connected to a
208V WYE building hundreds of feet away.  While the building has a neutral,
I would like to avoid sending the neutral out to the inverters as it is a
waste of materials. More wire, bigger conduit, neutral kits in disconnects,
etc.

The Symo manual indicates that there is a wye grid configuration with three
phase and a neutral. And there is a delta configuration with three phase
only. Both appear as though they can be set to 208V

I can't see any reason why I can't program the inverters at Delta and not
have a neutral. Am I missing anything? I tried inquiring with Fronius, but
it's a process and the conduit has to go into the ground today.

Thanks wrenches!
