I bought another USB->RS485 adapter (another Waveshare.) It is working and I can now see all 4 of the BMS'. The one weird thing however is that I had to set the Baud rate to 9600 in the software and in "Computer Management" on Windoze. Oh well. It works now.

Bought a new USB to RS485 adapter and it works now, albeit at 9600 baud (odd.) I can see individual packs as well as packs connected in series (set via dip switches.)

I'm having similar problems as well. I just checked both of my Waveshare adapters and I don't see the same numbers I'm having similar problems as the OP as well. I just checked both of my Waveshare adapters and I don't see the same numbers @tigerwillow1 posted. I think one of the adapters is...

I've got 2 of my 8 DIY Mason kits up and running, but I cannot get the RS485 connection to work. I've tried several different combinations: single battery/master using 2 diff RS485 to USB adapters (both are WaveShare) and 2 diff computers - both recognize the USB adapters when plugged in. 2...

Sounds good! Good point about Bulk->Absorb->Float. I have witnessed that behavior. That's interesting about the charge current. It seems like the SEPLOS BMS's are determining CC/CV. Do you have any data when the SEPLOS start to decrease the charge current? I'm wondering how closely it...

Ah. I see it now. Now that you mention it, I seem to recall my MPPT60's used to do something like that (I have the Schneider BatMon) and I changed something a while back and now they don't. Hum. The other thing missing from the MPPT's is the ability to flip to Absorb. I have my setup...

This is a timely post. I've just ordered 8 SEPLOS MASON DIY kits. Does your screen shot imply that the Conext Gateway can talk to the Seplos BMS? I just looked thru the docs and I don't see a Read/Write address to set "Maximum Charge Current" for the MPPT80. I have a MPPT100 in route, so...

I think we have the same BYD packs - mine are the 220Ah 24V packs. If you want 48V and you have more than 2, you have a few options. Parallel 1/2 of them to make a large 24V pack, do the same with the other 1/2, then series them. You only need 1 path to your DC equipment then. I have 8, so...

I have mine setup to use my own integration with Home Assistant: https://github.com/shorawitz/conext-api It's basically a Python application that uses Flask to create a server process that can query the Conext Gateway via ModBusTCP (any network connection.) The integration allows me to control...

Well, I finally got GWL to ship me a new cell monitoring board. It has worked for the last week allowing me to monitor cell voltages using my "conext-api" integration with Home Assistant. It is quite a bit cheaper than the Orion Jr. (and I already bought it) so I'm going to stay on my original...

I'm at 1.12 as well. Forgive my laziness for not reading the previous posts, but is there a feature/fix that you need to upgrade?

So this thread hasn't been updated in a while it seems. I've done a lot of testing with other BMS' and I'm pretty much coming around to the realization that the Orion might be the way to go. I've tried Chinese products (JK branded BLE and RS-485) and the quality is what you'd expect. The BLE...

Does anyone charge their batteries via AC2? I'm noticing that my current loads are still ~2Kw and the there should be excess power to divert to DC is possible.

I thought that too and I think that's the point GXMnow was getting to. But it always showed a value <100% and the Ah reading never made it. At any rate. I went into my settings reconfigured all AC2 settings to factory defaults. I have the generator running now (but now I'm low on gas. It's...

OK. That's a lot to digest. So I'm not sure about your 1st paragraph analysis. I was first seeing the behavior of not reaching 100% (on BatMon) before switching to Absorb/Float while AZ Sun was prevalent. I figure the BatMon is pretty accurate as it is connected to the shunt and it still has...
