Thinking about this more. Could I use the CHARGE NO wire to provide field voltage in leu of a second relay? I read in this post https://www.offgridsoftwaresolutions.com/ws500-user-forum/topic...

I repeated the download and update procedure. Same problems as shown above. I took the next step to manually install the updated firmware files directly on the SD card: I removed the SD car...
Wonderful, glad to hear. That is how it is intended to work. Nice and Simple. -al-
Thanks @al-thomason The 2.5.0 firmware update using your uploaded DFU file was successful on both of my regulators. I used the windows dos command line setup that I previously used for the 2....
sounds like you still dont have a complete install. Try reinstalling both update bin files. Power down for 20 seconds power back up but do not touch anything else until tomorrow morning
I have seen something like this before and believe it or not the solution seemed to be to leave it powered up for an hour or two, then pull the power for 20 seconds and let it reboot. Its almost l...
Hello, I was reading this thread on victrons forum and have a couple questions. It looks like my BMS is currently running firmware v2.7 The linked thread mentions a version 2.8, as well as a \"...
oh good, that sounds easy enough. Will give it a shot. Thanks for the quick reply! Update: That worked! Thanks again!

Today I put together my BMS and battery pack. The wifi module was on firmware version 1.5.8. I tried to use the REC-WiFi-module-Firmware-Update-1.6-HW2.0.zip to update my module. Everything appe...
Hello all, Yes, some teething issues! Perhaps to be expected, and including the refreshed Wakespeed.com website this past week. As to Firmware and Drivers, I might suggest downloading the Wa...
Yes, since they got purchased by Dragon fly they are having some issues. I have several calls in to my contacts but haven\'t heard back yet. As soon as I get it I will post it to the forum. ...
Where can I download the latest W500 firmware? Wakespeed instructions say to look at the \"technical\" page on their website. Did Wakespeed remove access? Also the STM drivers link above doe...
For the record, it is possible to drill and tap the back side of a Victron shunt to accept additional leads. cheers
In my setup, I\'m planning to only have a single solenoid and have it for low voltage disconnect (discharge) as all of my charge sources (less the alternator) are Victron and controlled by DVCC. Th...
You could also use the inverter disconnect opto output with a relay. This would effectively disable the alternator before a hi limit hard trip occurred by setting CHAR to about 3.6 and CHIS to 3.5...
It sounds easy enough. Why not just add a paralleling relay off of your BMS contactor coil and put its N/O contacts in series with the ignition input wire to your alternator. BMS trips, ignitio...
I have a 140 amp alternator (internal regulator) servicing my house LFP pack that is managed by a REC Active BMS. The engine start battery (AGM) is isolated from the house pack and is charged by...
You can use the generator start/stop functions associated with relay 1 on the Cerbo to \"gate\" or modify the charge enable signals from the REC BMS (assuming the REC active has charge enable simil...
You can connect the sense wires to the two large M10 terminals. I have done this in my own system, no problems.
Thanks. I didn\'t want to get the data off the network for the reasons you mentioned. I wasn\'t sure if I could just put the sense wires on the big terminals. It makes sense that you could bu...
No, and in my thinking you would not want to have to rely on a network connection to control your battery. The BMS both performs PID control and has several safety features that rely on the curren...
Is it possible to have the REC Active BMS make use of a Victron Smart Shunt? The Smart Shunt doesn\'t have any provisions for hooking up additional sense wires (not very smart IMO).
Thanks. I\'ll see if I can break out / export the relevant bits and post them here. Here\'s a screen shot showing basic operations. The Functions not shown sent various alerts to the slack chann...
I like your thinking here. Use your BMS to provide a single critical function and let your Cerbo provide specialized supervisory control. If you would care to share any of your node-red that wo...
Revision 10-04-2022 which is 99% there.
While on shore power, I wrote charge control functions in Node Red on the Cerbo GX. At first I tried keeping it between 30% and 60% but I\'ve found it easiest to charge to 100% and run them down...
Thank you again @Goboatingnow for keeping my little project on track! Much appreciated.
I contributed in a small way to refining the RGleason schematic. one point I feel very excercised on and I see it pop up across many forums HVE and LVE should be configured to be serious safe...
Discussion about rules are not always straight, because you can interpreted them sometimes different. see comments below: 1. If never paralleled than all is ok. As I mention I didn\'t read a...

This diagram uses the red cable. Why the red cable? Can\'t we use the same shunt as the REC Active BMS which is closer to the battery and on the black cable?
Dear Ben, Thank you so much for your reply and the corrections and clarifications and the answers to my questions. I have been using DIYsolarForum.com \"Small Boat BMS/LFP with Backup\" thre...
Another thing that not clear in you diagram, is where you install the voltage sense from the WS500. Think about that IF the REC is the \"system battery\" monitor in the Cerbo, you can not use SV...
Hello Rick Gleason, I only had a quick look to your diagram, I didnt check or all the details are correct!! To make a one contactor system you will safe costs. I think a two contactor syst...
Rick, Thanks, I had lots of help from some very knowledgeable guys, @Goboatingnow @svsagres @wholybee and John Harries. I had several questions, I hope you might know or confirm the answers...
Some good stuff here. Thanks for sharing!
Sure, the WS500 has a multiplier parameter, based on a 12V system to allow you to have any range of battery voltages, up to 48v. The REC Q BMS also allows you to have between 5-16 cells. The Vict...
