Hello All,
The utilization of the onboard 12v DC power supply is dependent on the Rapid
Shutdown Device that you are using, whether Tigo/APSystems/Midnite. Tigo has
many different solutions in their TS4 series of products. The devices that
utilize the RSS Transmitter only, TS4-A-F and TS4-A-2F receivers, will be able
to utilize the onboard 12v power supply to power the RSS Transmitter. It is
possible to power the RSS Transmitter separately from the inverter if it makes
the most sense for the project.
However, if you are using any of the other TS4 series (TS4-A-O, TS4-A-M and
TS4-A-S) these require the use of the CCA (Cloud Connect Advance) and the TAP
(Tigo Access Point) kit provided by Tigo to provide the PTO (permission to
operate) signal to the receivers. Both the CCA and TAP kit must be powered
separately from the included 12vDC power supply in the Sol-Ark as this exceeds
the power supply. We recommend that these items be powered by a 120vAC circuit
connected to the "Load" breaker of the Sol-Ark so that the CCA and TAP kit are
powered during a grid outage.
Thank you and have a blessed day,
Dustin Douglas

@DustinDouglas do you mind confirming if the Tigo RSS Transmitter is compatible
with the 12vdc power supply from Sol-Ark, and if not…what should we be doing to
supply power without having to rely on 120VAC output of the inverter?
Thanks,
-Chris

Hi Nick and List, that was my problem exactly.

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-
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)
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.
Enjoy your day, Nick

Hi Chris,
I echo Ronald’s experience. I
wasn’t aware of any memo from Sol Ark suggesting pins
15 and 16 should not be used for the Tigo RSS
Transmitter. The 12K and 15K manuals both refrence a
12vdc RSS transmitter to achieve rapid shut down.
Best,
Chris

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
