Yeah I understand what you mean. I don't understand the post I quoted though from you. You didn't say you had the EG4 hub connected to the inverter, you said you had the cable connected to battery #7, didn't mention the hub at all. So you have the other Ethernet in the splitter connected directly to the battery, or the hub? And then the other port of the splitter connected to solar assistant?
It looks like a relatively complex system. It looks like your 200 amp Nadar breakers are really being used as disconnect switches so you don't have both sets of batteries connected at the same time. Only comment might be that it's my understanding the Sol-Ark 15K (each) unit can pull/push 275 amps maximum. With a 200amp T-fuse you could blow that pretty easily should both inverters kick in and pull more than 200 amps.

Ohhhh okay thanks!! Appreciate that. Having solar assistant plugged direct into the battery let's you see them all individual? That's pretty neat. I'll be changing the way my system is set up right away. What dip switch setting do you have on battery #7?
My loads in my house will never reach 200amps even in a surge. I notices you posted a pic of you SA with battery info... didn't see the pack info like I've seen on SA videos see image. Heres a link to the video I got that screen shot from.It looks like a relatively complex system.

In my opinion, I always use the biggest cable available, you have a bunch of 2/0 cable, and I would actually prefer for my taste 4/0.
This is the cable I use, pretty cheap and super heavy/flexible.
Spartan Power 100% Pure Copper Bulk Welding Cable
Spartan Power welding cable is sold in bulk quantities, is 100% pure copper and feature an ultra-flexible EPDM jacket. Expect the best, get the best.
What pack info are you expecting to see? This is all the information available to SA, at least with EG4 batteries.
Here's an interesting video with a way to see individual batteries without multi pi's
The batteries in my system do not communicate with the Sol-Ark, the batteries communicate with the CommHub and the Hub talks to the Sol-ark using CAN Bus.
I think you might have misunderstood what I said, you can see multiple batteries in a single-battery array.
Perfect thanks
That comms hub is pretty cool then, nice.
Copy that I'm crystal clear now. I can't wait to do an experiment to see if a rack of 6 EG4 LL V2 batteries can daisy chain communications with 3 of the new EG4 Power Pro wall batteries. I already know that I can't have them connected in parallel with my 15k's without voiding the warranty (different AH, even though it would function without a closed loop communication) EG4 and the techs as Solar Sovereign made that clear. But I could see if I could connect them to SA and monitor them all that way even though I will only by using one group of batteries at a time. My wife says I'm like a mad scientist with all this solar gear.
Yes that was a bad video ignore that... my bad didn't see you picture with the pack information displayed before I went down another rabbit hole.
The cable you linked from Signature Solar is the same cable they send with EG4 batteries for communication with your laptop correct?
With regards to the PowerPro, you're going to be in uncharted territory. I'm not aware of who makes the BMS in that unit and it's not currently listed in the supported batteries for Solar Assistant.
Well, it is currently, it's my understanding the cable was different in the past, but yes if you bought your batteries recently from Signature Solar, say June 2023 or later I can confirm it's the same one. The picture of the cable on the website is out of date, the current cable doesn't have that green screw connector and instead is a nice molded plastic end.
I may be a little slow but what abbreviation does JBD and JK stand for?That comms hub is pretty cool then, nice.
Mine was a half question, half trying to help mr721 understand and make sure he did not miss the RS485 to USB conversion
I do wish SA could handle multiple battery types at the same time, but I was told it is a year out.
So I bought another JBD and now have a spare JK !!!
