Alan: Thanks for setting me straight about 3-phasing the Outback Radian
- I was not aware they are limited to parallel single phase applications.

Gary,
I was surprised by this information, as I had presumed that both units
were for single-phase only. So I checked.
Mary Raub in tech support at Outback told me that the Radian works
only in 120/240 single-phase, although they are stackable in parallel.
Someone in Schneider tech support told me that the XW can be used in
three-phase, up to six units (36 kW). Setup instructions are in
Appendix D of the XW installation guide, found online at

Thanks, Allan

Allan:
Also, you might consider using six to nine Schneider/Xantrex XW6048
inverters, or six to nine Outback Radian GS8048 inverters, in a
3-phase configuration, with a common battery bank.
Also, Schneider/Xantrex has an 80A 600V charge controller that may be
advantageous depending on the distance from the PV arrays to the
inverters.

Wrenches,
We have been asked for a design for an off-grid system to reduce
generator runtime for a mountain resort. Initial projections
(consumption measurement results not yet available) suggest 15-20 kW
of PV and around 30 kW of inverter capacity. However, the generators
and existing wiring are three-phase 120/208.
My assumption is that our only options are a set of six Sunny
Islands, or 9-12 Outback GVFX3648s. Are there any other options or
approaches that I'm missing?
Thank you, Allan
