[RE-wrenches] Back-up generator/inverter shut-down relay

[Benn Kilburn]

Hey Jerry,
Yeah, hard wiring would require quite a bit of trenching and wire. 
I was hoping someone would be familiar with a remote relay option or at least a manual reset relay that would include some sort of indicator for when it has shut off the inverters. 

Earlier today I was considering what you are suggesting. Seems like it should work. 
Anyone care to poke some holes in this theory?

> Does not sound like there is an option to hard wire a shut down switch so here is an idea l have used. Program the genny to run at 58 Hz. not yp this will keep the inverters ftom starting up. None of the appliances will know but as long as the inverter programming does not allow for 58 Hz then it will work
