Definitely sounds feasible, that would make more sense then selling a unit that you have to bypass the rx connection somehow and not telling you how to very well lol.

I have the same SCC, running at 24 volts, and it is wired as yours shows in your pics. As long as your cabling is good, I don’t think it’s a connection issue. I don’t know why it’s giving the BMS warning, as your BMS isn’t connected to the SCC.
I can’t see exactly what your battery settings are, but what I can see looks ok. I did note a voltage reading of 13.29. The SCC won’t think charging is needed at that voltage, I am guessing.

Volts dropped into mid 12s when pulling 100a and I pulled that for a few mins with no charging started, I’m out of ideas and I think 740GLE is right and it’s just a bad unit, which is unfortunate but what do you do.

That’s always a possibility. If you can get a replacement, obviously you can test.
I had my initial programming done by the vendor (BattleBorn) so I didn’t have to work from defaults. Minor adjustments are very easy, and it’s been running fault-free for over a year. It’s a beast of a SCC.
If there are any settings you’d like to look at, let me know. They are 24v settings, but you can convert them easily.
It’s showing his batteries at 12.8v so charging should be automatic.
With that remove jumper installed, can you do a voltage check across those terminals? You measured a voltage with the jumper pulled, ow test to verify the jumper has those terminals shorted.
Maybe someone else can test the voltage of the terminals with the jumper pulled and see if you have the same readings.

I can hook up 2 more panels in series for a voc of 240 but I technically will be 700w over paneled for the 12v battery, one of these days my other batteries will show up.

0 volts across when connected.
Maybe I missed it but has this unit ever worked?
Here's what I'd try:
* Power cycle (disconnect battery AND PV, leave off for a while; connect battery FIRST and then PV)
* Reset to factory defaults and reconfigure for LFP
* Cross-check the switch settings with the documentation to make sure it's set properly
* Update to latest firmware if it's not; make sure your Victron Connect is latest, too
Can you show us the settings page for that device? (EDIT: nevermind, you did that already)
I have a 250/70 myself but I've got it plugged into VE.Direct and it's been a while since I've used it in a standalone configuration -- but the only thing I did was plug in the VE.Direct cable.
It does seem confused about it being programmed to talk to a BMS. That's not right (hence my factory reset comment).

I really appreciate all of the replies, I haven’t been part of a forum this helpful since a car forum I was part of years ago. I sent the controller back today and second day ordered from altestore so I should have it tues and I will update if that was the issue or it’s still happening. I think this time I will disconnect my internet before connecting the Bluetooth as this forced me to update my previous unit right away.

Just an update, the new controller works fine, I just got a dud.
Good deal! Thanks for the update. Victron duds are rare.
Sometimes it’s the simplest thing as the root cause (dud unit) that takes the longest to find out, pulling out hair looking at settings, updating firmware, double checking wiring.
Glad you got it up and running looks like a really nice unit.

Hi all, just wanted to add something to this rather old thread from my fresh personal experience. Maybe it will help other people.
I just had the same issue described initially in this thread after fist installing my DIY lifepo4 battery, and I exhausted every possible setting and I was ready to call the vendor of my SmartSolar charger.
In my setup I have all the Victron equipment (smartshunt, smartsolar, inverter) connected with ve.direct cables to my rapsberry pi with VENUS OS and it seems the SmartSolar wouldn't turn on unless the Raspberry PI was also up and running. Initially I had only connected the battery and the smartsolar and no charging was happening at all. Then after I turned on the Raspberry PI, it immediately started charging.
Hope this helps somebody.
