<p>OK, while I would prefer to not get into compiling code onto an
ARM, my main question would be, how do you get the voltage value
into the Arduino?</p>
<p>Rectify the AC voltage and then voltage divide down to the chip
input pin?<br>

Couple Disconnect</div>

</div>
<pre>Folks,
Can anyone share a parts list for setting up a AC couple disconnect?
I want to couple a
non-frequency response grid-tied inverter to a
battery based stand-alone inverter.
I have only 8 amps output from the GT inverters, so can use 10A relay
contacts.
I want a device to monitor AC voltage and latch a coil on when it raises
above a set point (250VAC). I then want a timer to release the latch
after about 1 hour.
Sound about right? Are any vendors selling such a device? How about a
parts list from Digikey?
Thanks,
Mark Frye
