Under dvcc, limit charge current, and limit voltage need to be on.  Make a setting, just higher as the BMS "goal"(CVL CCL).  The GX will take the lowest from, manual setting, or from BMS....

Good that you have thing working, nice feedback reports I dont know exactly why you had the zero amps charging.I dont see any relation with frimware update. Not any update that could have solve t...

Reporting back... I followed the latest instructions, and they worked perfectly. WiFi module is running smoothly now. THANK YOU!!

Okay... here are the latest results. Firmware Update... before I did the two tests I updated the firmware from 2.4.3 to 2.5. Here's the logfile after updating Firmware.  Updating firmware did...

Unfortunately, everything on the boat is LED. I will stop by an automotive store and pick up a DC low wattage light bulb and give this test a try. As for the alternator test... what do you mean by...

Thank you. I will give this a try the next time I'm at the boat. Is there anything else I should try if this does not work? I live about 45 to 60 minutes away from the boat, so I'm not able to vis...

Thanks for the replies.  I was able to do some of this via the VRM remote panel.   DVCC: First, here's the DVCC settings: When I first connected and reviewed these settings the 'Co...

In VRM, you can also add a widget that show CCL and CVL, can you post them here, from the same time line as above screenshots, VRM?   Also post the widget from VRM, cell minV and cell maxV.&...

Not sure what firmware you are running but version 2.9 has added some enhanced top voltage control. It starts on page 24 of the manual and you can find the update and manual here:   ...

Only a short answer, no more time at the moment.    Having high voltage alarms after 18 months, I see that more times.  Before the cells where nice in balance and there will be no al...

Nice report back. The test on the blue FIELD wire shows that the regulator is working. ALthought the test with a multimeter can be not correct, because there is not any load on it.  Do you ha...

Hello Jamie, Could you try with another SD card. Format the card. Have both files copied in the root from SD card: update.bin and spiffs.bin file.   I never had a device that didn't rebo...

Another challenge I'm dealing with at the moment is the BMS not seeming to slow down the charging rate of the Victron Multiplus 3000 the battery gets toward full. This seems to result in the high v...

Thanks for the replies. I appreciate the help. Pins... I removed the fuses and cable, and checked for pins and all were in the their proper positions. Fuses... I checked the fuses on the voltage ...

Thanks for the reply. I made it down to the boat this evening, and removed and formatted the SD card though made sure to save the log files . After reinstalling the card, I logged on to the Wi-Fi ...

One extra note. According the manual, always remove FIRST both fuses, before disconnect the connector from the WS500 device.

The thought that first comes to mind is that you may have a pin on the harness that is pushed back a bit.  Maybe try opening the case and using a jewlers screwdriver, reset all pins.

Jamie, Ben is right, it looks like your upgrade did not get properly installed.  I have found it can take hours for the update to process.   We have tried to document that in several plac...

I'm not sure or you have followed the correct procedure with uploading the firmware files but anyway at this point I suggest another method to update the firmware. 1. try the reset button from WiF...

Suggested test: 1. Check the fuse in the red cable to alternator.   2. Check fuse voltage sense wire.   3. Post picture back side alternator.   4. With engine running test wit...

I've got a WS500 within a LiFePo system with a Balmar XT250, REC Active BMS and Victron Multiplus & Cerbo GX. It's been working quite well for 18+ months, though this past weekend my alternato...

I did restart the WiFi unit, and it did show up on the WiFi devices after restarting. I was able to reconnect to it and I was able to see all the BMS detail on the home screen. However I was not ab...

A few thing to try. Did you restart the WiFi unit. Did you restart the BMS. Did the WiFi unit after repower/reset show up under WiFi devices on your phone?    

Recently upgraded the firmware of my 1.2 version of the Wifi module. All was smooth and went well, however after the upgrade while I can still see the homescreen, I cannot see the firmware page (no...

Hi Hank, I am happy to hear you reached resolution. I am very interested in more details, as you know these SMA can be querky if parameters are off. Let me know if you have any other issues. Than...

Fred, No problems. I finally figured out what was wrong. I don't  know how the parameter changed on the SMA, but we changed the start parameter from null to auto and then to start which did t...

Ok, thanks for the feedback.  I like the Idea of connecting the Wakespeed up to the Altenator shunts because I then have more options for control.  Connecting up to the Battery Smart shun...

Also your SOC calculation may be incorrect, to me it appears your SOC should be greater than 60% assuming you are using lifepo4 chemistries 

Hi Hank, Sorry for the delayed reply. Are you still having issues? I have a few systems setup SMA and REC products.   What is your incoming source of electrons? Are you DC coupled with a ch...

If you are using a REC or Victron BMS your WS500 should be able to pick up the current on the VE.CAN port.  Not sure about the Smart shunt, but I would expect so too. I  do not like rely...

This is for anyone else who may have trouble getting the new 2Q to communicate with Victron. Assuming you've wired it all correctly AND have the adapter that connects to a Cerbo or other Victr...

I currently have a marine twin engine application with a Victron Smart Shunt connected to a Victron Cerbo GX for house battery monitoring.  I just purchased two Wakespeed 500 regulators to con...

Is there a method to determine what the REC Q BMS has requested of the Sunny Island 5048U?

Hey Fred, we don't currently have an SMA demo set up here.  Do you have any ideas for this gentleman? Thanks, Rick @Fred Egelston 

I installed the REC-BMS some time ago. Recently, I wanted to add two additional battery strings, necessitating a change in configuration to a master with three slaves from a single REC Q BMS. This ...

Closing the loop on this thread .... many thanks Ben.  The problem was finally diagnosed by a tech in Maryland.  When the solar power system was installed, the the WS500 was reconnected t...

The EVE cells are proving to be a good cell and so long as they are well matched you shouldnt have any problems with a 3P4S configuration.

The GX is not the device that calculated the "remaining time". In setup with a Victron shunt, or smart shunt this info comes from the Victron shunt. I think REC dont calculated this, and sent thi...

@Rick Hi thanks for your reply, I am currently building a 3P4S setup with EVE 304ah cells. Just checking to make sure the Rec Active BMS is fine with 3 cells in parallel as well? Thanks!

Thank you Rick, that helped clear things up for me. The system is now running fine.
