@Trond This is exactly what I was looking for! Thanks so very much!

@Rick Thank you Rick. I assumed the forced float status is because the feature in connector is configured as a bms charge enable lead which made me think that part of the setup is working correctly...

We include a PC config tool with the WS500 and the PRO version allows you to import the raw data and re-run it on a chart or export it to excel in something a little more readable so I ran your num...

Hi - I have a ws500 setup with a balmar 6series that has been functioning well for about 30 operating hours so far.  Today, at startup the system ran normally for 4 minutes and then shutdown t...

@Jonas It's on the Rec-BMS main website: https://www.rec-bms.com/rec-accessories/ Under the wifi module, it has a firmware update: https://www.rec-bms.com/wp-content/uploads/2023/03/Wi-Fi-FW-Upd...

and just caught your reference to a local A/C line.  Because the shunt is such a sensitive reading there is a chance that induced AC power may be affecting the reading.  Make sure the 2 w...

This sounds like a wiring problem.  This is a millivolt reading so it is very sensitive to any poor connection. Ideas: Check to make sure all crimps are clean and tight clean the connecti...

I sent a message. Hopefully his megacorp overlords will let him reply! :)  

I did get an reply from Tine about this. And from my understanding all BMS`s send ID 0x3..  And this can be changed to 0x4.. with special FW for BMS but then you need to customice programmin...

@Mike Support has acknowledged this isn't expected bahavior.  At their suggestion I reverted the firmware from 2.5.0 to 2.4.3.  Surprisingly, 2.4.3 is much better here.  To me the 2....

I thought there was one in the large comms and programming manual but could not find it.  I think you will have to reach out to Wakespeed directly for help on this one.  Maybe try al@wake...

Does anyone have a pinout diagram for the large connector to each of the wire ends?I had a tech onboard today to verify some items on my engine and he was THRILLED to see the connector and then sad...

Hi. I currently have two REC A-BMS connected to the same Cerbo. One BMS is ID 2 and other is ID 4 in RS485 network, so far so good. But when I connect them both to CAN-BUS there seems to be some...

And now it's back to normal.  🙄 I did install a short length of AC wire in the same vicinity (6-10") as the shunt sense wires yesterday afternoon but the log shows the initial issues coming u...

Well, that was short lived.  Readings are going haywire again.  Victron battery monitor shows +2.8A which is in line with the equipment currently running and limited sunlight fom solar to...

I've got the REC ABMS on my liveaboard sailboat.  Yesterday (according to the logs)  I had the current reading from my shunt go a little haywire.  It has been reading between -50A an...

@nebulight Where did you find the 1.61 firmware on the "main site"?

The problem persists.  I've verified all connections, verified that the WS500 is reading the shunt correctly. I haven't heard any response here or in other forums. How do I get support for t...

@Mike Our boat has been in storage for the past few months and so I've let this issue lie.  We're back on the water in a week or two and I then plan to push to understand what is going on...

I am going to include Al fromWakespeed in this thread and see if he can provide any insight. @Al Thomason  @Rick Admin 

I have exactly the same problem and I know I am not alone. I am concerned about the effects that this fluctuation/spiking will have on all the powered devices. Surely it can not be dismissed as "no...

@Michael Thanks Michael. I am a little gunshy due to probems with the system over the last several months. I am regaining confidence in it. I had alternator issues that nobody was able to diag...

@Brent The idea of the BMS is to control the regulator, and will override your settings, as Al is pointing out that one of the points of CAN bus communications is if the cells are getting out of b...

Quote from bonsys on March 16, 2023, 12:19 pm I have a general observation to share. After installing firmware v2.9, we discovered that negative values for Opto(x) CH Hysterisis (OPxH) are no long...

Quote from Rick-admin on March 16, 2023, 1:50 pm I would think you only need 2.9-2 if you have an older system and do not have the Wifi module Hi  Carl. So far as I know there is not a version...

at Carl Dewever: \"\"hello, thx for that info, however, where can I find that kind of info? It looks like I\'m missing some documentation... can I program these 2 parameters with the wifi-modu...

@Al Thanks Al. I have the REC BMS but the regulator is temporarily disconnected to establish a configuration that would work without the BMS. The regulator will be reconnected to the CANBUS sh...

@Michael Thanks. I am going to raise the float voltage to see if that resolvese the issue. the 13.0 value was from the default LiFePO4 profile. 

@Brent (Disclaimer:  Al of Wakespeed). As suggested by Michael, it sounds like the float voltage needs to be adjusted.  But am a bit more concerned by:      "I have ...

Hello.  (Disclamer:  Al of Wakespeed). I am not an expert here, but I think you might (guessing here) be seeing some odd things on the main Cerbo screen, as from waht I understand the Ce...

Brent  One thing that caught me connecting the REC to the Wakespeed is the data cable is not a straight through cable and so you need to make sure you get the pins correct there are only two ...

Brent It sounds like your SOC is dropping because your "float" voltage is set to low (I assume your "revert" voltage is the "float" voltage)? By setting your "float" voltage at 13V the regulator i...

Guys, after talking with Al, he confirmed that the WS500 does not integrate with CVCC yet. From Al \"And at all times the WS500 directly takes its guidance from the BMS -- Victron has not extend...

I would think you only need 2.9-2 if you have an older system and do not have the Wifi module

No, its a setup screen in the \"Tasks\" tab of the WiFi module, with several parameters and alarms that can be configured

Rick, thank you - can it be done without WiFi module?
