EG4 FlexBoss + GridBoss + Tigo CCA

I just talked with SS tech support and they told me External RSD +24 / Ground for CCA.

My installers are working it now and should finish Friday. I have the GridBoss, FlexBoss and two indoor wallmount EG4 batteries.

Seems to be conflicting word. Jess at Signature Solar, this might be something to get an official answer on.
If you're installing the system this should be pretty easy to confirm. Activate internal RSD in FlexBOSS and verify whether there's power present at Po/G and at +24/G.

Also, can you post a picture of where Po and G are at? I'm not seeing them in the manual.
 
Hi! On page 29 of the grid boss manual it shows a diagram to wire in an optional external rsd. If you need any further assistance, you're welcome to reach out to the tech team at 903-441-2090 and we'll do all we can to help!

Hi! What page 29 appears to show is how to connect an emergency stop between FlexBOSS and GridBOSS. What it doesn't show is precisely where I'm confused which is how to interface that so that we also trip a Tigo CCA. What I think we all need is that same drawing that also shows how to include the CCA.
 
Any updates on this? Would be really nice to see an RSD doc for the Flexboss / Gridboss like they have for the 18kPV. :(

Jess, is there a diagram showing how to wire the Tigo CCA to stop button, Gridboss, and Flexboss?
 
I was wondering the same thing.

My understanding is you run SW and +12 from Gridboss to SW and +12 on the Flexboss, then run G and +24 on the Flexboss to your CCA PWR - and +.

Then when you press a RSD button on Flexboss OR RSD switch on Gridboss it would initiate a complete ESS shutdown *Assumes closed circuit comms* (battery breakers flip, Flexboss pulls power, which in turns pulls power from CCA which then kicks off a RSD shutdown on the Tigo modules (due to loss of TAP comms), also Gridboss flips breakers.

Need to test when I get everything setup but this is how I understand the setup currently.
 
Question - What is everyone running between their Gridboss and Flexboss for the RSD wire? I assume cat5e will be just fine but I could run a 18awg tray wire as well if needed.

I would guess that would be fine as there is t really any current going through wire and I was going to do that but went with a security camera wire using 18/2 to run my RSD. I was limited on space in my access holes so this wire ended up being smaller than a CAT5 and worked perfect. Will be using same wire for my Tigo CCA to power/RSD
 
I talked to Signature Solar and they confirmed Cat5e is just fine. I ran one twisted pair into each port, no problems and I can confirm that the RSD button and switch work as expected. Plus it removes power from the Tigo CCA.
