| Aloha Chris,
We have numerous Sol-Ark systems with Tigo TS4Fs where we have the transmitter wired to the 12v supply of the inverter, with no issues to date. Sent from a IPhone, with touch screen keys on the fly. Please excuse shortcuts and typos.

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.
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.
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
