William,
I do have some new PS Generator start modules(GSM) if you or anyone is interested. Contact me offline.

It also eliminated the digital display and control panel. It was intended as a low-cost "base model" of the SW series (I heard some installers that the initials stood for Pile of ...). So I don't think that these units can start the generator, unless you can locate an auxiliary genstart unit from that era. You would also need a SW remote in order to program the units.

The inverters power 120 only loads (shared neutral on two feeders) so the inverters need to be stacked. 2. When the batteries get low, the inverters start the generator. The inverters transfer through from the generator power to the loads and charge batteries. Can the PS pair do this with a three phase generator? I am beginning to think not...

No stacking necessary. A regular SW stacking cable won't work for delta connections because that assumes the phases are going to be 180 degrees (120/240) and not 120 degrees as for 208V delta. There was a 3 phase version of the SWs which required a separate 3-way cable and different software in the SW itself. boB On Thu, Jul 28, 2011 at 12:23 AM, William Miller <will...@millersolar.com> wrote: Friends: Is there any way to connect two SW series inverters to two phases of a three phase generator? It seems to me that one could connect three SW inverters with the right stacking cable (or am I confusing Outback inverters with the hub jumper set properly). Any input is appreciated.
