@Rick   Did the clock battery long shot and no change, also took the time to test all six internal fuses and they are fine. 

@Rick I have only seen this a couple of times and it was because the wifi module is connected to the load side of contactor instead of the battery side and the power is disconnected from the modul...

@Bill Caswell you could use a service called tailscale to create a VPN into your network. This is one of the ways I access my system via starlink.  You will need to have an always on network ...

@Richard @Rick  

@John Yes I have, this would be one of the first things I did in troubleshootingTrouble shooting steps have been power cylced multiple timesverfied all connections (although nothing changed)tried ...

Have you tried turning the BMS off and back on.  That is what I do when mine messes up and it has worked so far!

Hello all, hopeing for some late night help. I was attempting to upgrade the firmware on my ABMS via the WiFi module and something failed. BMS is non functioning now, I get a single red flash and n...

Hey Tony, the big change is that the 2Q uses better connectors, has more memory, a real-time clock and has a built in precharge circuit.  It also requires the Wi-fi as the standard interface ...

@Rick Thanks! I fear it's a 1. but due to a different operator error.    I wish the Q's were still available and I'd purchase a back up due to being off grid. I've been trying to compare ...

An error 15 is caused when 1)  a cell tap wire is disconnected while still connected to the BMS and it created a voltage imbalance, burning out the highly sensitive ADC circuitry. 2)  Y...

I'm turning on my BMS for the first time and one getting Error 15.   It says contact support but support says ask here, idk? Has anyone ran into this?    I can't access it through Wi...

Hi, I need some help. Setup: REC Active BMS Tyco relays Pre charge unit I have a Victron Multiplus that I want to connect a Tyco relay that shall open at overvoltage, I also have a Pre charge ...

UPDATE January 2025   With recent updates to both the Cerbo and new REC 2Q and Active series BMS's these systems now work better than ever together. VE.CAN support  DVCC control to ...

UPDATE January 2025   With recent updates to both the Cerbo and new REC 2Q series we can now confirm that both the WS500 and the REC BMS can now reside on the VE.CAN bus of the Cerbo.  ...

Did you connect it?

@panagiotis Thanks for the reply. I don't need to hunt for the data because I know it's there, it's getting the MFD to display it, and the editing interface in the Axiom lists general categories li...

Just get an NMEA analyser and check your self if you can find any pgn 

I would like to access my REC Wifi module on my boat. I have Starlink and have been told that there because of how Starlink assigns IP addresses using CGNAT that I will need to use some other techn...

Great, that makes sense.  Thanks  

This parameter is used only for maximum system load current from Inverters and Inverter/chargers, so you would enter "1" here.  It will regulate all chargers using DVCC

I have a WS500 (non Bluetooth) installed along with a Victron system with a Cerbo GX, and a Raymarine Axiom 9+ MFD running the latest firmware. All of the above is functional and networked via the ...

I've just purchased an Active, and am in the process of setting everything up in my garage before installing on the boat.   I'm not clear on the number of charging devices entry.  In my ...

@nworker becasue there is no real time clock (RTC) on the Q Series, my graphs simply show an incrementing integer sequence along the X-axis.  

Can someone explain how the passive balancing alogrithm works on the the REC Q BMS. When you reach the balancing start voltage, in this example 3.45v, does the REC balance one cell at a time by dra...

@Ben   I've done some additonal reading and in your experience should the BMIN BVOL values be the same for active vs. passive balancing?  Perhpas I am thinking about this the wrong way,...

@Rance Thanks very much for your reply. My set is working pretty well, but I am still working through some issues. Sometimes the field strength bounces between 0 and 2%, when it should be charging...

@Rance great to hear.   Thanks for the confirmation, yes, the fix will be in the next release 2.6.1.    Till then reach out to Support, or maybe Rance can help ya. Thanks again for ...

@Ryan @Bill C.  I have the same system, it has been up and running for over a year. Connecting devices is pretty straight forward. I have my REC and WS500Pro connected to the VE.CAN ports on ...

Problem solved! The -DEV firmware mentioned above did not work but after a few emails and phone calls, Al got me sorted out with a patched firmware. They are working on releasing the new revised f...

@Arkom Did you succeed in driving the MG1 with the Wakespeed after all?Thinking about the same for a boat 48V system. ThanksA

@Rick @Al    Thanks to you both for the quick response. I did the update and now it seems to be stuck unresponsive with a very dim green led when in running mode. The app doesn't recog...

@Al Thomason    Thanks for the quick response Al.  If you email it to me at support@ogm-energy.com  I will see that Rance gets it. Best of the season! Rick

@Rance Kilbourn   (Disclaimer:  Al from Wakespeed). OK, we have found something in the WS500-PRO code that looks to be your issue.  Or at least, could well be…  It is r...

@Al sounds good, thanks for looking into this. Let me know if you need more details on my setup to try to replicate the fault condition on your end.

Disclaimer:  Al from Wakespeed. Sorry to hear you are having issues, let me look into this some.  Should of course be transparent, as the source code is common.   But let me set up ...

We havent done any testing with the Pro yet so I am going to include Al from Wakespeed in this thread and hopefully he will have some insight. @Al Thomason 

I cannot get firmware from this download link: https://rec-bms-na.com/rec-bms-releases-new-active-bms-firmware-2-9-4/   What is the right location to get the latest firmware?

Greetings All, I have 4P4S 920ah 12v LiFePo bank with a REC Active BMS, Cerbo GX, 1200w of solar with 4 MPPTs, MultiPlus-II and a WS500/Balmar XT-250. I have had my system working on my boat for o...

after a lot of head-scratching I finally got this:
