Hi James,

The utility may only allow one configuration.

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

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!
