Thank you! It's been a lot of fun doing all this.
1. Extremely easy - configured the JK and got it communicating with the others, connected it to the Sol-Ark, enabled sol-ark battery coms.
2. From what I've seen you can have a max of 16. Each JK connects to the next in a daisy chain fashion on the right hand side ports. The master JK (Set to ID 0 - this is important otherwise parallel doesn't work.) connects CAN to the Sol-Ark.
On the sol-ark side, there is a single port for CAN / RS485. I wanted to buy a nice breakout cable from the solar assistant folks but they were out of stock and I'm impatient so I built my own. Other than that, you just make sure the CAN pins match up.
Here's more detail for what I did.
1. Configured my JK BMS settings the way I wanted with ID 1 and did a firmware update. Made sure the CAN protocol was set to 002 - PYLON
2. Set the ID on the master to 0.
3. Configured the slave JK's with the same settings and updated the firmware, each time setting the ID to 1 to do it then changing to their position.
4. After each one was done, I connected a single RS485 on the farthest grouped RS485 ports.
5. Connected the CAN port on the Master JK to the CAN port on the sol-ark with the proper pin,
6. Turned on Activate Battery
Once that was done, the Sol-Ark just saw it and has worked ever since. I made sure I had all the settings in place as if I was doing open loop as a precaution.
