Hmm.. I read this, did the math, and double checked my settings but I still do not understand why it is not recharging. In order to trigger a charge, I have to set the  \"END of charging voltage hy...

Hello, Today I went to wire up my pre-charge module and noticed that the diagram in the latest REC ABMS Manual, as well as the lates REC Pre-Charge Module manual, illustrate what appears to be a...

Good morning! I am using a customized version of #7. The exit amps settings in #7 dont work for me. Anyway, I do believe some parameter is limiting Field to 31%. Not temps. I am using a PBF of 1...

Check you have the Firefly \"configuration file\" profile loaded.  You can download it here:  https://www.wakespeed.com/product/ws500-advanced-alternator-regulator/#wc-tab-title-support Also, ch...

The Q series has firmware that is keyed to the serial number, so you just need to send in your request to REC, along with your serial number and they will get you an update. It can be installed ...

Thanks, Firefly bats so no BMS. Dual engine. Controlling WS500 flashing Green Acceptance, slave WS500 orange flashing.

Does anyone know where I can get an updated software version for the REC Q unit that has this parameter option in it?  I have the 2.6 software of the BMS and the 1.6 version for the Wi-fi module bu...

I am having the same issue. Victron says I need ABMS firmware version  2.7 for full integration with the WS500 and mine is currently 2.6. All I find in downloads at REC is the manuals. I did get th...

In my opinion, you can allow the BMS to push out the battery temp but I would hardwire the current sensor in parallel with your Smart Shunt(just use a couple of ring connectors on the power wire lu...

Yes, the USB will power up the WS500 but it will go into alarm after 30 seconds on a low voltage condition.  If you have our WS500 config tool, it should notice this and ask if you want to put the ...

David, I think this post may help with your questions. https://www.offgridsoftwaresolutions.com/ws500-user-forum/topic/rec-abms-not-recharging-after-reaching-full-charge/#postid-1153 Cheer...

This summer we did some testing on a firmware tweak that would provide better control at the very top of the charging range using the larger SI-Q series BMS.  I put together a draft charge profile ...

75.9% today, 13.27 volts, still no charging occurring ;( Also looks like I forgot to mention I am on 30A shore power at the moment.  MP3k is set to 100A charge limit

As I get closer to wiring this up, I wanted to confirm my understanding on charge control is correct. ABMS is at stock configuration: cell over-voltage switch-off per cell 3.85 V over-vo...

I found this video from wakespeed where they show only plugging in the USB cable.  This worked for me!  

For the record, I did experience this a little bit after my upgrade, some of the values I entered would get submitted with the decimal in the wrong place, or omitted entirely.  It did not persist t...

I am trying to power on my WS500 to check firmware version, upgrade, and configure via my android.   I have bound the Ignition Wire (Brown) and Alternator Positive (Red) to +12v Alter...

ahoy! I convinced myself that the balmar 618 was a waste of time and received the WS500 kit today.  I\'ve got a few questions around operating it in tandem with the REC BMS. From reading the ...

Hello, My system has been setup for a few days, and it is either not re-entering charge mode, or I dont know how to determine when it should be (i.e. an SOC level, a voltage level, etc.)  Most like...

It could be one of several things !)  If the LED is flashing orange, your BMS is controlling it and you will need to check your cell voltages and temperatures to see what is pulling it back 2...

Hi, Batteries were at 50% leaving the anchorage but max output from dual big alternators was 95A. Regulators started in bulk then later to accept but output low and V around 27V. V slowly climbe...

With the WiFi module (1.6) and the REC-BMS (2.8) configured, I have a couple of questions My understanding is the REC-BMS checks the battery voltage and requests charging from the SI. I have inc...

I started from scratch to make sure I have all the right software running in the BMS and WiFi. reloaded the BMS firmware hardware reset of the WiFi module reconfigure WiFi module inst...

I set up a Q Series BMS last night using 2.8 firmware to start testing to see if I can duplicate these out of range numbers you are getting. I had an old WiFi module, so I upgraded it to 1.6 but...

I am going to set up our demo board with a Q Series today (I only have an Active and Master/Slave up now) and will see if I can replicate your issues.  I have pinged REC tech support to see if they...

Sometimes the answer is right in front of you and you can\'t see it. From that same forum post: \"Some of the devices are controlled by applying ground so ground is connected to fused input a...

Backdated the firmware by removing the SD card, deleting the old file versions, reinstalling the card, and restarting the WiFi module. I\'ve attached a screen shot showing the software version. ...

Here is the DB9 pinout from the BMS.  Just grab a DB9 connector, a 120 ohm resistor and a phone patch cord and you should be able make one. Keep in mind that there are no standard CANBus protoco...

yes, there are files for both hardware 1.2 and 2.0.  Maybe you grabbed the wrong  HW version files.  Try again with the hw2.0 files And just in case I am posting 1.5.7 files here, in case you ne...

Boy do I dislike software troubleshooting. I used update to reload the files with the versions you provided (which are not different) in the order you recommended I try and got the following err...

The files are all the same between the ones I downloaded and put on the SD card and the files provided above.

The first thing I tried was switching browsers from Chrome to Edge. That eliminated the first problem with the menu blackout. The menu blackout problem was solved by repeating the upload process. ...

Just another thought, what browser you are using?  Maybe its browser specific

Strange that both of you are having the same issue, yet many people have had no issue. I did some of the beta testing on this is version and it worked very well. I grabbed a fresh copy from t...

Still does not work correctly after doing a full reset and reconfiguration. When setting the maximum cell voltage and the battery pack amp hours the same erroneous numbers are displayed. Seems like...

Scott, Did you experience the same problems with entering settings?

Hi All . , finally got around to hooking up by batteries, however i have hit a roadblock. i have a Sofar ME-3000SP inverter , this has a CAN connection, problem is that it uses a RJ11 connection...

I just went through the process of updating to HW2.0-1.6.0. I performed the same procedures that Rick suggested less waiting a few hours. Installed the .bin files on the root directory of the SD ca...

Thanks. 3.6A would be pushing it. Probably better to just use a second relay and avoid blowing that little fuse. The alternator is the only charge source not controlled by the CAN bus so usin...

cool, its a 5 amp relay, with a 3.6A slow blow fuse as I recall (fuse is internal replaceable PCB socket mount)
