As Ben mentioned this is a Windows driver issue.  The interface cable has an FTDI chipset to convert the USB to RS485 and 99% of Windows PCs will automatically install the driver, but if yours did ...

Hi I\'m having some issues with connecting to the REC Active I\'m running Windows 10. When starting the BMS Control software  (as an Admin) I get an Error -1073807343 message (See Error me...

Hello Paul, I just check the app. Probably you made the wrong settings. All voltages are what the batter manufacturer advice. If you have a DIY self pack, any brand, best setting to cho...

Hey Paul, You may want to pass this on to Al at Wakespeed. http://www.wakespeed.com/contact.html  

Can I politely suggest the voltages on the lithium profiles in the WS App are too high? I can back with references if you like. 3.6 is a max, maybe once a day, with 3.5ish being safer. Depen...

I could see that if you had a network with NG then N2K then NG again as some devices will likely have an IN and OUT network port with some sort of opto isolation circuit. You could likely get ar...

Having your Multiplus shut off on loss of comms will be function of the settings in the MultiPlus.  I did a quick search and found some \"loss of communications\" parameters in the Venus/Cerbo here...

I think they need to be seperate buses / terminations with gateway Some of the RM backbone devices block traffic if not powered. I\'m not sure which one\'s yet. Testing.  

Hello! I have the BMS connected to Cerbo GX, which is also connected to a Multiplus 3000. I have enabled DVCC/SVS/STS like the BMS manual suggests and I am running an unexpected problem: when I di...

I have found that by breaking out your power sources you can get over this.  I have had success with powering my NG components off of the power source on the RM Evolution autopilot and then only co...

I have had success in the past by adding a hose attachment (or making one from a big funnel) to the back of the alternator and bringing in cool outside air.  In one case I even added a bilge blower...

I did the sd card update methode a few times. No problem, it is updated in a very short time. Always better todo a format first, this way older backup files are deleted. If you need them, ...

Thanks -- good input. I wasn\'t able to recover the original SD card, but formatting a new card and moving the files there appears to have resolved the issue.

Thanks for the update. You have to be careful to let it go through the full update after re-powering and wait a good 10 minutes for it to do its stuff before pressing the reset or disconnecting ...

I attempted the update and it looked like it had worked, but appears to have corrupted the SD card. I\'m getting a \"PROBLEM WITH SD CARD, LOGGING IS DISABLED.\" I\'ve  emailed the head office for ...

Thanks for your answer.  Now the issue is heat created by charging the LFP battery at a high rate of current with the large 120 amp Balmar and small Yanmar engine -21 hp.  Are there any external ad...

Don, not sure if we got an answer to you on this one. You can use the derate setting in the SCA parameter.  This will limit the field output. The PBF,(Pull back Factor) can also be used in as...

Glad you got it running and thanks Ben.  I was 90% sure that was the backup workaround fix but did not want to recommend something I hadn\'t tried or confirmed yet.  Appreciate the input!

I read that it works already. Or alternatively, if you can remove the SD card from the module and plug it into your computer, you can just copy both files onto the card and the module should upd...

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.

Seems like you are trying to install the spiffs file first.  I found it would work if the update file goes first. If you are following the process correctly and still have issues you will need t...

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: \"...

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...

Firmware update is now ready to go.  You may find it a bit confusing so we did up a quick video too.  No release notes though. download firmware update here:    https://rec-bms-na.com/downloads/...

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 ...

Thanks Rick Will have a go at this today BW Michael

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 see how it comes back each time.  Do you get a cell ...

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...

here you go

Sounds like you did not pre-balance your system by paralleling all cells overnight, or you have mismatched cells. The BMS is working overtime to bring them into a balanced state and having to re...

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...
