All, I believe what Chris is referring to is something I was
initially confused on during a Solark install I was involved with
last year. Uncertain if the manual has changed but in the Solark
12k manual dated April 2, 2021 on page 23 it has a line saying-
<div class=""><br class="">
<div class="">Note: Tigo Optimizers are compatible with the
Sol-Ark 12k (Do not use the built in 12v Power supply in the
Sol-Ark user area to power the Tigo Optimizer TX transmitter)</div>
<div class=""><br class="">
</div>
<div class="">I too had to confirm with Sol-Ark to clarify these
details. I’ve not looked at any of their newer manuals to see
if some of these notes have changed.</div>
<div class=""><br class="">

<div class="">Enjoy your day, Nick</div>

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 class="">
</font></p>
<p class="">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 class="">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
