Gregory, Hello.  I have reached out to support to have then follow up to your question.  Please be looking for that and sorry for the delay.  (In short, all the phases are documented in the WS50...

Al, can you help out on this one? @al-thomason

Alternator Centric is an older term that I understand from WS is not being used anymore.  Basically it means control to the limits of the alternator, instead of the limits of the battery, and to do...

I have the same question and I cant see anywhere in the manual that discusses the twin engine/twin shunt issue. No idea what \"Alternator centric\" might mean. In my case, twin large case altern...

Jon, I have a similar issue: system drops to Float early. I dont think I am pulling amps down at the time. No luck getting any response from Wakespeed. ANy luck at your end?

No matter how I adjust the various settings in my custom profile I cannot keep my alternators at Acceptance level voltage long enough. The WS500s drop to Float at about 96% and 20A in. With my Fire...

It would be helpful if I could call up and export my custom profile settings in readable text. I am having some issues in setting up my system and i would like to have my settings reviewed by an ex...

Off the top of my head I was thinking you could use the tach wire from the alt to drive a relay that would basically give you an output whenever the alt was turning.  You are going to get a pulse o...

I guess you could partually solve this letting the WS500 Charge lamp output drive an small relay. Then you would have to use an \"Normal Closed\" output on the relay. This should give you the...

I have a setup with 2 WS500 connected to two ElectroMaax Cruiser High-Output 140A.  My boat has an alarmsystem that requires the traditional charge lamp signal (GND when alternator not running/faul...

You are right, with the US language setting it works. A little bit strange. Thx for the help.

The Android App has an function for updating FW. So far i have NOT been able to get this to work. Is there some trick to it?

Some customers are having issues with trying to update their WS500 to the new 2.5 firmware. There seems to be two potential issues the STM driver seems to have issues with USB3 ports and sl...

REC WiFi firmware updates for 1.5.7 are now posted to the REC-BMS North America site https://rec-bms-na.com/product-manuals/#7-12-wpfd-rec-wi-fi-module And installation tutorials are here:   ...

Thanks for sharing!  I will see if I can get this build posted to the REC-BMS-NA website in the next few days for everyone that might need it.

In Norway we have the same issue. Works when choosing US Windows Language. But I have seen other installations where it did not even work with US language. Hope this will be fixed in next ...

update since upgrading ... now HW:1.2  SW: 1.5.8 I am getting weird responses ... when i submit - i notice the wifi connection bounce and obviously get no response. Its like its causing my Wifi ...

It worked fine for me. Did you press the \"Enter\" key after entering the value? Is your Windows PC set for European currency where the the comma and period are interposed?  (If so, you will ...

Two things: When the CANBus is pulled in does your WS500 LED turn orange, showing it is in remote control mode? Maybe you have your voltage multiplier set wrong in your WS500 and it is set to...

You set the parameter in the SCO string to zero to use the dipswitches.  Here is a page snip of what it looks like in the WS500 tool we include with the WS500  

I\'m bit confused about the dip switch vs configuration software.  Do the dip switches set the basic parameters then the configuration software fine tunes those parameters OR does one override the ...

I have just installed a REC BMS with Victron GX, 2 x solar regs and Victron Multi 24/3000/70-50 and 2 x WS500 regulators (currnetly only trying one) The WS 500 is showing on the Can bus but does...

Hi Rick I tried to modify SCA / Derate

Hey Chris, What variable in the WS500 are you trying to change with the tool?  I will test it and confirm. And unfortunately when I last looked I was not able to find a MAC compatible version...

Thank you for the information. I have tried to change the values via the WS500 Config tool. There seems to be a bug in the software. It is not possible to change these values to 0.25 there. I\'m ...

Does anyone have a wiring diagram for the ABMS and the REC BSLRD  and the Blue Sea 7713? thanks  

 If I am not mistaken the Venus is based on the BeagleBone, not sure what the Cerbo version uses. Cerbo GX uses Venus OS - the very same version that\'s on the Rpi. :)

I\'ve just found the Victron product. Its not surprise  no-one buys them - £523!!! Good grief. They do the community a solid by open sourcing VenusOS, but then price connectivity like that when USB...

You will need a CANBus hat for your RPI or an MCP2515 board powered and connected to the GPIO on the RPI. I set one up years ago, but when you look at the Cerbo with all of its additional IO, re...

Hi, has anyone set up their REC-BMS ABMS with communication with a Raspberry PI instead of the Cerbo GX ?  At the moment I can\'t see how to  get VE.Can comms to the Raspberry PI. thanks in a...

See page 14+15 in the manual. I would prefere option #2.       1) Connect the ALT+ (Red) wire to a 12v source With this approach, the field power source is supplier f...

Here some technical details of the 48V alternator

My tests in the workshop were about 10v-12v for the field

Should be 56v to charge the LiFePo4 battery controlled by a rec q bms

How much is the output voltage?

Hi guys, I have rebuilt one of the two engines (Volvo Penta D2-30) on our catamaran and changed the previous 12V/115a alternator to a Mahle MG1 48V/100A. The internal charge controller has been r...

I\'ve seen a system 3s, 4p, no bridging between strings, and it\'s in balance after 4 years. Good cells are amazing Only way to do SOC control I know is using switched outputs on BMV712 to trig...

As I read the ABYC requirements there seems to be a need for an Alarm before disconnect, and possibly seperate charge and load bus control. It already seems to meet the temperature and charge moni...

Thanks for the suggestion, Damian.  The original SD card wouldn’t format so I swapped to a new, formatted card and got the same result.  I did use a 64 GB SD card and wonder if it is too large for ...
