[RE-wrenches] 2 SW inverters on three phase

[William Miller]

boB:

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...
