<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>
