What kind of generator? If a Generac, and depending on the
controller vintage, it may be possible to install their SMM (smart
management module) load shedding module which does not require
separate control wires. <br>
<br>
Down side is they're rated 50A for resistive loads and 40A for
inductive loads. If they work, one would be required for each
SE7600. <br>

<br>
Give Generac a call, or maybe a Wrench who sells/maintains Generacs
can comment on the suitability of this solution. I've used them for
load shedding, bot not for inverter shedding.<br>
<p>I believe one of the 8 settings will always lock out the unit on
grid failure / genset operating, as opposed to be one of the 7
total load based priorities.<br>

<div>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</div>
