William,
Just a minor note: if I recall, the PS model was the first to
eliminate the generator autostart function and auxiliary relays from
the unit. 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.

I'd like to run the inverters in the normal fashion with
generator input
(no PV): (I'd thought these were SW inverters but they are PS
series).
1. 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...

If so, you should just be able to connect each SW from
neutral to
hot. 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.

- 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.
- Thanks,
