[RE-wrenches] Inverter On/Off Switch use Outback FX

[Kent]

Mac,

I think you've got an elegant solution to the problem. All you need is 
an inexpensive relay and to program the Aux output for loadshed. I 
believe shutting down the inverter with the remote on/off contacts is 
actually less stressful on the inverter than opening a relay or 
contactor on the load side.
