<div dir="ltr">Chris, <div>Assuming there will be 48V batteries in the system - connect the Tigo transmitter via a 48V to 12V power supply and come off of the battery bussing. If there are no batteries now, use the 120V-12V power supply from the backed up loads panel - then when they get batteries that panel will remain live even during power outage and allow panels to remain on even with grid outage. You will need to install an additional rapid shutdown switch in line with power to the transmitter if rapid shutdown is required or desired.. If there are no batteries now, then solar can't stay on anyway during power outages.. <br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">Sunny Regards,<br>Kirpal Khalsa</div><div dir="ltr">Oregon LRT#25<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><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Nov 16, 2022 at 6:33 AM Christopher Warfel via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p><font size="4">Hi, We are doing our first system with these two
devices. The inverter is SolArk 12P (mutimode) and the Tigo
product for RS is the TS4F. Tigo has me a little bit walking in
circles. <br>
</font></p>
<p>I told them that SolArk says not to use the 12VDC RS output
terminals for connecting the transmitter. I gave them the
attached drawing which they ask for, which shows the transmitter
connected to a 120VAC/12VDC breaker which they supply. They told
me to wire the 120VAC source to the main service panel so the
array would shut down on loss of power. I told them that is
exactly NOTwhat I wanted to happen as that would stop the battery
charging when there is a loss of utility power. I said I wanted
the 120VAC source to be the back up loads panel. After about a
week of calls and emails, I got an email back saying to use the
SolArk 12VDC terminals for RS. I just emailed them a screen shot
of the SolArk manual that says not to do that.</p>
<p>At this point, I am asking anyone on the list to let me know how
they wired the transmitter successfully. Thank you for any
guidance, Chris Warfel<br>
