i've got an offgrid setup with a 6000ex inverter and 6 EG4-LL (v2) batteries. works like a charm when i set the BMS to USE. but if I switch it to EG4 the display freaks out with low battery icon and it nonstop beeping even though im rocking over 80% charge! Checked the comms with a signature solar and all good there. i unplug the cable and boom! error 61 pops up like it should. i tried rebooting but nada! any hot tips??

Haha, I believe that's really annoying because I've been there. I reset the batteries after charging the DIPs. Now remember, if it's working again, you need to wait a while before trying to configure it to EG4 mode.
 
If it works in USE mode but not EG4, its likely a DIP switch or firmware problem. Try to double check DIP settings, make sure its firmware's updated and try resetting battery #1 after changes. That usually helps clear things up.
 
Check this out also, sounds like a comms issue with the EG4 setting. Have you tried swapping the ends of the comm cable? It might just do the trick! Also, double-check to make sure the inverter's lithium battery type is configured correctly. If you're still having trouble, it could be a firmware problem. Are you running the latest version?

Honestly, sounds like a firmware mismatch or the EG4 protocol is just half baked on the 6000EX, cross check your baud rate and port assignment too, but if comms are green and it still wigs out, then screw the EG4 setting, let it run on USE and sleep at night.

Appreciate the insight! How do you check or change the baud rate and port assignment? And when you say "run on USE," is that a more stable protocol for the 6000EX?
 
If the EG4 mode is still acting up, some just stick with USE mode. They keep an eye on things using Solar Assistant or BMS apps. It's not as simple to set up, but it's steady and you're in charge.
 
If EG4 is acting up and USE mode works fine, just keep using USE. Wait until there's a firmware patch or clearer fix for it.
