<p>I think you just use an automatic transfer switch similar to
those used for back up generators. We are looking at one for
backing up a community well pump that will transfer to a multimode
system if the utility drops out. Chris<br>

</div>
<div>Does anyone have experience with a 200A outdoor transfer
switch that will automatically seek voltage? Meaning that if
priority voltage source (grid) isn't available and second
source is available it will switch to it with no external
communication? We are trying to do a whole house backup, and
critical load panel isn't possible. This may be common, I
just haven't done it.</div>
