Hello Rick - I have a related question. The Multiplus is an inverter/charger so same conductors are used. To control charge enable and discharge enable, Victron has separate digital inputs (all Vi...

Hi Salvey, I thought it best to reply inline, so please see my replies in blue. Rick - thanks for your prompt response. What you have described appears to integrate multiple charge s...
One more question: Is the \"OGSS Demo\" the charge information that I would see from the Wakespeed, on the Cerbo GX Touch display? Thanks.
Rick - thanks for your prompt response. What you have described appears to integrate multiple charge sources with an LFP bank. Questions: I prefer not to have three different interfaces f...
Hi Salvey, The REC BMS functionally acts as a Master DC source on the CANBus network via the Cerbo, and becomes part of the Victron Ecosystem. You just need to set a few parameters in your Cerb...
Hi Rick, I am configuring a similar system. I have a 12V @ 560AH LFP house battery bank. My goal is to get a REC-Active (12V) BMS to control a WS500, Multiplus II inverter/charger and SmartSolar ...
I am setting up a similar system with an REC Active (12V) BMS and Victron Multiplus II Inverter and Wakespeed 500 regulator. It is critical that either charging system disconnect if CAN fails. I\...
Thanks Rick Maybe I just dont understand how this works - are there not two Relays and two Optocouplers? RE1L and OP2L being Relay-1 (pin 1,2&13) and OptoCoupler-2 (pin 16&17) respect...
not sure what manual you have but here is the link to the current ABMS manual for use with Victron. https://rec-bms-na.com/download/8/rec-active-bms/340/usermanual_abms_victron.pdf It looks l...
Hi Maybe I\'m just missing something, but going through the values in my Active BMS, I don\'t see a complete instruction set in the REC documentation. I\'m missing the commands to query or se...
Ha! One DOA factory original USB cable. I just got my new OffGrid cable, connected it and lo and behold - off to the races!
Hey Pete, it is starting to sound like you have a bad 485 cable. I would grab a new one at this point. We sell them as part of the PC Windows software or you can go back to where you got yours o...
I am quite convinced that the cable is dead. There\'s no indication on three different machines when plugging it in. I\'ll see how quick I can get one shipped. Again, thanks for the help! &nb...
If the rs485 is working, then the REC is all ok. Try another usb cable. And as mention before, first have the comport showing corretly in device manager. No reason to start software before ...
Nothing - no beep, no change in the device manager. Yes the BMS is on - I\'ve tried every permutation with it on or off when I plug in the USB. To confirm that the 485 works, I connected the ...
I added my previous post, please read that again, maybe some tips help you. Restart windows. Plug in usb again, do you hear any bleep or nothing? Not any change in device manager? ...
Ben, the error is on the manually created COM port. There is no difference to the view if I plug in the USB or not. And no, the COM port doesn\'t disappear when I unplug the USB. The two vers...
From device manager screenshot is a fault at com 7. This is a windows comport fault, you need to solve this. If you disconnect the REC device, does this com 7 disappear? Or is th...
There is a difference though now when I run the BMS software. I don\'t get error 1073807343 anymore, but rather this new 7346 message. End result is still the same - No COM port to select in the...
First of all, thanks for the help! Here\'s the screenshots from the device manager. First one is with no COM ports listed. Plugging in the USB cable makes no difference - same view with or wi...
Open device manager. After that plug in device. You should get one new line in device manager. If not under comports, maybe on another place. Reconfigure this line. If still not work...
Hi Rick Thanks for the info. I installed the driver\'s (on two separate Windows 10 PC\'s) but still have no luck. There is no response/recognition when I plug the USB cable into either mac...
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 ...
Before connecting in the REC software first check or the comport shows in windows \"device manager\". Check comport number here and connect in REC software to correct comport. If not in device ...
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...
