Did you go through Tine's troubleshooting tests above? And verify the pin connections at your AMP connector?
This will be handy for many customers. Thanks for taking the time to document this hack. :) To maintain IP67 a grommet might do the trick. I always kept this cheap little kit onboard. https...
I can't ever rember a Master failing so we have never had one apart. Grab a Torx#10 and slide off the cover. If its like the BMS's look for a small black/brown approximately 1cm s...
We're happy to help if we can. Please send your serial # to support@ogm-energy.com and we will see what we can do for you.
If you purchased your equipment from us, we would be happy to take care of it for you, but if not you will need to contact REC head office and give them your serial# to request an updated bin file
You may want to consider adding one of these to allow your DD alt. help charge and top off/balance your pack while on the road :) https://ogm-energy.com/products/orion-xs
We have quite a few customers with SMA grid tied systems so hoping they might be able to help here. One issue that came up recently was some firmware bugs in the SMA where it has problems communic...
yes, a 12P4S should work well for you. Connecting the 12 cells in parallel is now commonplace, so long as you are working with fairly closely matched cells. I think you will notice a go...
We just added it back to our REC NA website downloads. Here is the link https://rec-bms-na.com/product-manuals/#7-8-wpfd-rec-active-bms
We dont see you as a customer so I can't see what tool you are using for configuration but we are happy to help none the less. Not sure what the support comment was all about... The wifi module ha...
We have just created several REC BMS kits to make it easy to purchase and save! You can find them here. REC Active BMS Kits REC 2Q 16S Kits REC Large Scale High Current and High Voltage Systems
REC has fixed this bug in its latest release. You can find details here. https://rec-bms-na.com/rec-bms-wi-fi-module-firmware-update-1-6-3-just-released/
After working with Wakespeed for more than 7 years we grabbed a Zeus around Christmas and threw it onto a test system we had set up. It was still early in its evolution but seemed to be built...
Hi Sturla, When the REC BMS is connected to the WS500 it will take over control of your Alternator charging but all safeties and interlocks should still over-ride the DVCC/CVCC control signal from...
no, they are meant to drive something like an LED directly. If you want to drive a larger load you will need a relay with a very low (15ma) draw or a powered relay like this. https://www.ama...
Thanks for the feedback. Pushing it on to REC . @Tine Andrejasic
Mark, Your WS500's will work fine but a 12V alternator will usually put out 15V max. The WS500 will only control the current coming out. You will need to find alternators that ...
The pdf diagram you sent does not show any shunts They are small. Just zoom into the negative bus. I assume that I will install one 1000 Amp shunt on Batt "A" and Batt "B" negativ...
The shunt only gets installed at the Master when you have a high voltage series connected system.
no, the 1Q's are fine too. You will be able to see the total current flow from the the Master. To check that each shunt is working, jut power off one pack to verify each bank is working...
Good question, In this configuration you will only need 2 shunts. You set the shunt coefficient in the Master and it will broadcast it to both of the slaves. The Master will take the s...
@Bill For a 2000/50 shunt when I canlcuate it I get: 0 .01953125÷(500÷2000) = 0.078125 So for most standard ranges here are the coefficents 100/50 = 0.00390625 200/50 = .0078...
The update process first copies it to the SD card, then over the next several hours it slowly updates the local processor memory and then needs to be rebooted so that was likely your only issue. A...
Lets include Al from Wakespeed on this one. He may some insight @Al
From your description it sounds like this will work just fine for you by interupting the remote on/off switch. And yes, the switch will power down your BMS, with all parameters saved.
Sure, just send a quick email to support@ogm-energy.com and we will send it to you
We havent ever had to use this but hopefully Tine from REC can help @Tine Andrejasic
Hi Peter, I can answer a few questions here for you. There is an extra output that can be configured using the Tasks section of the WiFi for your ssplit bus system For a 22 cell configuration yo...
This project is still alive but moving slowly. We hope to be able to put some real time into it this summer
From Bob Pogue One major thing that I see that is missing is a manual charge initiation option. You’ll often want to fill the pack while driving even though it hasn’t reached its disch...
We are going to need to get REC head office to give us some input on this one. They are closed until the new year but by way of this post I am letting them know. Any ideas on this one Tine? ...
This seems like a pre-release board and we dont have any experience with it. You're best to contact Al at Wakespeed al@wakespeed.com
yes, the Cerbo should be connected direct to the battery so it does not lose power on a trip. Interesting note about the loss of comms. It makes me think the BMS is not the problem. Did you...
I have pushed this back to REC but it will be after the holidays before we hear back. Best of the season! Rick
Lots of other detail on the battery pack but I am not seeing it either. I will put in a request to REC to see if we can add that in a future release
Hey Chris, I will pass this back to REC head office and see if we can get their input on this one. Thanks for the feedback.
Once the REC BMS passes the CANBus info to the Cerbo, at that time it is treated as any other DC souce so you want to look on the Victron side of things. Maybe verify that your REC is set as ...
