David,<br><br>This is for grid-tied carport structures which may be installed in several locations on the East Coast where the minimum temperature varies from 5 degrees F to -20 degrees F and I would like to maintain one standard system for each situation. Three strings of 12 modules fit the carport exactly and work well to 5 degrees but then the cold puts the voltage over 600. I could do 4 strings of 9 but then the high temperatures in summer cause the inverters to drop out due to low voltage.<br>
<br>I could do three strings of 11 and have 3 dummy panels but would like to avoid this kluge.<br><br>Thanks!<br><br>Lee<br><br><div class="gmail_quote">On Mon, Jan 10, 2011 at 5:44 PM, David Katz <span dir="ltr"><<a href="mailto:dkatz@asis.com">dkatz@asis.com</a>></span> wrote:<br>

We never had enough interest to warrant getting a UL listing on the
product. Is it for grid-tie or off-grid?<br>

I think Dave Katz at AEE had a solution, although I don't remember
the details. You might contact him.<br>

<pre>Wrenches,
Does anyone know of a UL Listed low temperature, over-voltage bypass
device like the dis-continued Apollo Solar product? I need to knock
out or bypass one module of a string when the temperature gets below 5
degrees F. The Apollo product was appropriate but is no longer
available.
Thanks!
Lee
