Hello,
I've been searching for the "best" way to enable RSD with the Tigo Optimizers and EPO with the Sol-Ark 15k. From what I've seen, the best method seems to be using pins 15 & 16 on the Sol Ark to drive a relay at the Tigo CCA. After that, there have been two methods.
1. Relay NC...
Everything I found was no more than 3 90's in a pull. I have a little less than 3. The final bend to get on the roof is about 67°. I have an LB at each end.
This shows a little better. (And also my first ever conduit bend so I didn't think I did too bad.)
I got the BMS and Sol-Ark talking with the BMS in parallel. It turned out to be super easy, just set the master dipswitch to 0 and the first to 1 and it worked. It reports up to the Sol-Ark everything that's needed.
I got my roof mounted transition panel and the conduit up to it ran but I...
Well that wasn't a fun process but it's done! The ATS is now my primary N-G bonding point and all the grounds have been separated from the neutrals at my main panel. At the same time, pulled new 2/0 copper to my inverter and I would say the cleaning up the N/G issue took longer than pulling...
2nd battery pack up and running! Got the JK BMS and the Sol-Ark to talk over CAN. Still need to figure out how to get the BMS's to talk in Parallel but I can actually test it now.
I tested last night and got my JK talking to the Sol-Ark 15k. A straight through cable would have probably worked but I swapped one pin for the GND connection.
It's been terrible! The only days it turns out to be nice, it shows rain a few days ahead so I schedule something else.
I'm about 1.5 hrs south of you! Thanks from 45814!
So far I'm pretty impressed with the 15k, it's been easy to work with so far.
Saturday is supposed to be nice so I'm hoping to finish up getting my mounting rails on the roof and start working on some of the wiring. I'm really looking forward to throwing some PV power at the Sol-Ark.
