Generac version which requires signal from generator) to transfer. Basically looking for a dumb version which transfers based on loss of grid voltage, and then reconnects based on re supply of grid voltage. </div><div>The Gerearc version which was installed today relies on feedback from the generator which senses loss of grid voltage to authorize the transfer switch to toggle to back up mode. When the grid comes back the transfer switch switches back to normal mode without feedback from the generator voltage sense wires but not the other way around. </div><div><br></div><div>Thank you!</div><div> <br clear="all"><div><div dir="ltr"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">Sunny Regards,<br>Kirpal Khalsa</div><div dir="ltr">Oregon LRT#25<br>NABCEP Certified PV Installation Professional<br>Oregon Solarworks LLC<br><a href="http://www.oregonsolarworks.com" target="_blank">www.oregonsolarworks.com</a><br>541-299-0402</div></div></div></div></div></div></div></div></div>
