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 t
Chris,
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 rem
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. Roland ShackelfordNABCEP CERTIFIED PV INSTALLERPreside
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

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 wi
As of the March 2022 manuals there are contradictory statements:
* (+15, -16) 12V power supply for RSD transmitters: such as TIGO and
Midnite Rated for a maximum of 1.2W (100mA @12V)
and
* TIGO Optimizers are compatible with the Sol-Ark 8K (Do not use the

Greetings Fellow Wrenches;
Based on glowing reports from the RE list, I finally used Fortress for a
battery replacement for a long time customer. Overall, it seems to be a
better solution than others I've seen. However, we are having issues.
First the two batteries are supposed to be linked t
Hi Ray,
I have been having a difficult time communicating with Fortress as well. I
filed a support ticket several times and only got a response a couple of
days later asking another question that was easily answered, but then do
not receive any reply to that without filing another support ticket,
Hi Ray,
I would suggest pushing the latest firmware update to both units.

I finally heard back from Fortress, I'm going to try their suggestion of
"equalizing" the batteries at 55.5 v, and adjust some settings. I'll
report back to the list on what I come up with. This is an interesting

So did you properly configuer the master slave battery config, I have
several set up with no issues SOC is within1 to 2% and volatge is the same,
what inverter/chargers are you using are you still connnected to bat temp

Thanks Kent, I would have thought they would have this clarified by now.
I think that we will just use a remote switch and not use the pins. It's
starting to snow here soon, so this needs to be done. Chris

@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

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-2
Wrenches, Christopher
I have done quite a few and per solark have always connected in the
inverter with no issues, Now with that connecting to the output side it
would do much the same work until it did not then shut off the modules.

The issue as I see it is that the Tigo RSS Transmitter and the APsmart
transmitter are both rated to draw up to 800ma. The 12VDC output of the
Sol-Ark inverters is limited to 100ma. Since some have used this
successfully I suppose that means that either these transmitters don't
really use more than
