Quote from Derek Dickson on September 23, 2022, 7:02 pm Did you figure this out? I had this problem as well and i needed to lower the balancing voltages. I did not, what did you lower the bala...
Oh, I also want to do this, but I have a system with a REC Q BMS already in service. Can that be setup to do it as well? I guess the REC WiFi module would also fit into this.
Quote from Trond Arvid Røsvik on June 7, 2022, 2:17 am Yes, but did you activate DVCC like its described in the REC Manual? Does your victron units indicate \"External Control\"? Yes and yes. ...
Quote from Trond Arvid Røsvik on June 6, 2022, 3:10 am Also, if you setup your system using Victron chargers and CAN bus regulated charging this should also not be an problem. Can you please elab...
Quote from Trond Arvid Røsvik on June 3, 2022, 9:10 am Do you have the older version of the 16S BMS with flat top? The newer models have (small) cooling fins. Anyhow this could still happen. ...
Quote from Trond Arvid Røsvik on June 2, 2022, 3:31 am Internal failure is due to excessive balancing and overheating of the BMS. Nothing to worry about really. How do we define \"excessive ba...
The voltage graph during balancing a couple days ago: If I look at other balancing sessions, it appears it is always cell 4 that lags:
Quote from Tine Andrejasic on June 1, 2022, 5:52 am If the BMS has to work hard to balance the cells (new not pre-balanced cells or old cells ) it heats a bit over the set threshold. BMS only sign...
Hi @rick_tech_support, Seems the BMS throws the internal error every time it has been balancing for a while. I\'m correlating the data and it appears the error is thrown 10 minutes after bala...
I don\'t think I updated the BMS. It\'s currently running v2.7 and I purchased it from you around a year ago. I don\'t think the temperature spike was spurious, since it clearly happened after b...
I loaded the logs and happened to catch an error: I assume > 50ºC is bad? The cabinet around it is not that warm, clearly.
Yeah, I get that, it\'s connected properly and reading all data. I see the request go to the module with the password in it, but it fails. Can that password be changed? i.e. did I change it with...
This is pretty strange, it tells me password doesn\'t match no matter what I do. Have you seen that before? Should I try restarting the WiFi module?
Perfect, thanks. For some reason I can\'t seem to get it to unlock. I\'ll try a different browser…
What is the simplest way to send it a command? I have the WiFi module and the BMS is connected to a Cerbo GX.
Good Day, I got a single, seemingly random, \"Warning Internal Failure\" from the Q BMS. No alarms are visible, now. Should I be concerned? A.
There is a REC & Victron guide, somewhere. Does the Cerbo GX see the BMS and it\'s various data outputs? DVCC must be enabled, as well.

The idea of 14-16 self-contained 12V LFP batteries, without any kind of monitoring of their state, is too scary for me. What happens if one of them decides to shutdown?
Quote from Kees on February 1, 2022, 12:30 pm 64x 280Ah LFP? to replace 40x 200Ah gel? Should be less LFP no? I was told by a batterie supplier that 14x 24V 280 Ah LFP would do.. Right! You a...
Back of my napkin math says you currently have 48 kWh hour of useable battery capacity in your gel cells. So if you are going to have the equivalent, or maybe more \'cause it\'s always better, you ...
You have nearly 29 kW of maximum power generation and a just over 12 kWh of LFP. That is not well matched, particularly if you are trying to charge at 0.5C, or 6 kW. Also, 14 cells in a 2S2P lay...
I tried again, got the same error Restarted the module Loaded the Firmware page and noticed that the SW was now at 1.5.1 (??) Uploaded update.bin, no error this time Uploaded spiffs.bin...
I will download the file again and check, but I\'m quite sure I started with the update file. Maybe I\'ll restart the module, then try again… A.
I\'m going to assume this is because my module has firmware v1.1 and that video shows v1.2.
Hi @rick_tech_support, I just pulled up my WiFi module and see that it is at firmware v1.1 (HW:1.0 SW:1.1), so I want to update it. However, when I upload the update.bin file, I get an error: \"...
I see various mentions of REC Q BMS and then sometimes specific talk about a REC for Victron. Is this just a standard configuration that you apply, of is it completely different hardware? My Q B...
Just happened to watch your recently posted firmware update video @rick_tech_support, and saw that your module appears to have way more options than mine. I only have the IP setting, and only the l...
Does REC post release notes or change logs for their software?
No idea why my post didn’t work, here is what I meant to say: is it possible to change the REC WiFi module’s IP address out of the 192.164.x.x range?
Hello, The REC WiFi module defaults to creating its own WiFi network and an IP of 192.168.1.184. I successfully reconfigured it to connect to my local WiFi network, but then realized that it is ...
Quote from Rick-admin on December 3, 2021, 3:56 pm Give it a few days to try to get itself balanced, or help it along as suggested in previous post. Then do a few deep cycles and recharges and ...
Thanks for the quick response! I did, in fact, top-balance them to 3.65v a week or so ago, before putting them in series. But one of the cells was lower by just about 0.1v when I powered everyth...
Good Afternoon, I turned on my system last night, then turned on the PV this morning. The battery should be very near 100%, though a single cell appears to be lagging. I now see the BMS throw...
Thanks for the quick reply! I do have a Cerbo GX and just realized that the MultiPlus has VE.bus ports, not VE.Can, so it has to be connected to the Cerbo GX. For fault tolerance, I am hoping...
Any hints on having a REC Q, VE.Can MPPT, and MultiPlus inverter/charger all on the same VE.CAN bus?
