3000EHV-48 and Ruixu Communications?

[pinkertonfloyd]

So I'm new, and I'm installing a 3000EHV-48 with a Ruixu Rack Battery for my first install
For the life of me I can't get it to communicate. (Always get Error 19).

Using the Pin 1-2 Cable, I've tried all of the protocols (only protocol 4 is documented in my manual as "EG4". But I've tried them.
I also tried using pin 6 on the dips on the Ruixu.

Everything I see online is for the larger 6000, and it's menu is different.

Ideas?
Thanks for any help.

Here is a link to the manual that contains the protocols for the 3000EHV. You can find these protocols on page 19.

After some research, it appears that the 3000EHV and these batteries may not be compatible for communication. However, you can set the inverter to "User-Defined" mode and operate it based on voltage settings.

That's what I was afraid of. When I bought the batteries I was planning on using a Victron System. But it was OOS, I figured the EG4 3000 would work since it's basically a MPP variant (which Ruixu supports, but in CAN mode, which it looks like the EG4 doesn't support (look like that unit can only do RS485?). Guess I should of done my homework... I've programmed the voltage (charge/float/cutoff) into the USEr mode for now.
I'm using this as a UPS for a server rack mainly. To last through California Rotating Blackouts.

Correction, Ruixu does support MPP in RS485, misread the chart.
Protocol ID

1 is CAN for Victron/SMA/Studer Inntec/Sofar, and RS465 for Voltronic/RCT/MPP/Alpha.
2 is CAN for Sol-Ark/Solis/Goodwe/Deye/Growatt/SAJ/LUXPOWER/Megarevo/INVT/Sermatec/TBB/MUST/Sunsynk
3 is CAN for Schneider

You can always try to return it and get one of the EG4 batteries so you can have that communication. If you figure out a way to get them to communicate, feel free to reach out and let me know.
