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

[Mac Lewis]

Hi Benn,

I assume the transfer switch is not over by the generator.  If that's the
case, there are typically many ways to do it utilizing a contactors that
senses the utility side of the transfer switch.  You can also use the
control signal that sends the signal to the generator to start.  That is
usually a 12V signal.

Good luck
