I have, connected to the "grid" with the inverter off, the power comes from the grid (rather obvious).
That defeats the purpose of the transfer switch. The inverter should be left on all the time if you want automatic switch-over with no loss of power to the loads.
If I turn on the inverter, while connected to the grid, the power comes from the inverter.
You've got it connected backwards then. Grid power should power the loads even when the inverter is on. You need to plug the molded plug into the inverter. The bare-wire source connection goes to grid power. And, obviously, the other bare-wire connection is your loads.
So, when the inverter is on, power comes from the inverter, period. Even if you are still connected to the grid.
Negative. Why even bother to have a switch if the inverter always powers the loads when on? As I said, your switch is connected up backwards. The molded plug goes to the inverter. The other line goes to the grid source. Which was why Xantrex put the molded plug on that switch - to plug into the ProWatt Inverter.
How do I know this? I have one with a ProWatt SW600 for my network backup power. The inverter is on all the time, and it shows 0 load until the grid power dies, then it shows a load by indicating it's drawing about 40 Amps from the battery bank (confirmed by the LinkLite monitoring the battery bank).
Cheers!
