Yes, its as simple as that.  The WS500 has a parameter that allows you to reverse it with software but I believe the REC requires you just reverse the wires

I am charging my LFP pack and the software is showing a negative value for my charge current. I have the two wires going to the shunt connected so the one that is identified as negative on the batt...

  Feedback from Korolev Alexey, support engineer, Yacht Devices Ltd   I am interested in controlling a power switch (like the Switch Control YDSC-04) YDSC-04 is a button pane...

I am interested in controlling a power switch (like the Switch Control YDSC-04) from an NMEA 2000 Tool running on a PC. I see from the documentation that PGNs 127501 and 127502 are supported, but c...

It looks like Victron is now working on the WS500 integration! This means the Victron Venus product line will now recognize the WS500 and integrate it into its network. To stay on top of its ...

Hi, I moved this to our forum as it may be of interest to others. The SI is basically a Q Series with custom CANBus integration code for a specific vendors charger and/or inverter such as Victro...

Hello! Do you have experience with the REC-BMS SI in a Victron-based setup? I believe it should work well with the Cerbo GX over Canbus, and that I could use the REC-BMS LCD in addition to the C...

Also, the registration key is included with your final Completed order and can be found near the bottom of the page.

Blaine, Hello.  Rick asked me to chime in:  You are correct.  What happens is the REC BMS will send charge needs and directions out via CAN which both the WS500 and Victron\'s CCGX receive.   Th...

Can I accurately conclude that this integration requires the REC BMS to be installed to glue these other two pieces together.   So Victron CCGX + W500 alone do NOT integrate,  but Victon CCGX, W500...

Wakespeed has been working with Victron to have a full integration with the Venus style products and as now waiting for Victron to finalize their side of the interface and release it.  Currently th...

You found it before we could get back to you.  Yes, the pinouts are in the WS500 manual For your second question did you give each ws500 a unique address?

The pinouts are different between the W500 Can interface and Victron CAN.   With that corrected, the first W500 shows up on the CCGX CAN device list....  Not seeing the second W500.

I am in the process of installing a new battery bank, external regs (2x W500) and REC BMS.  In my \'taking small steps\' approach I installed with W500s first and want to get them working with my e...

It seems that recently Microsoft has changed some security settings, but the fix is pretty easy. When you go to launch the WS500 Config tool app from the Desktop Icon, instead of using your left...

I can not register my software tool.  I keep getting an error message saying it can not connect to the Registration site.  I have verified my internet connection and even tried a VPN.

Basically the BMS passes several parameters back to the Inverter via CANBus which allow the 2 units to work in harmony to provide power to the home or back to the grid.  The BMS also works to provi...

I need to connect a 16 cell LiFePO battery bank to an SMA Sunny Island. (SI) Your website indicates that this BMS is able to control the battery charge from the Sunny Island.   Can you verify thi...

It is key to remember, the ASCII stuff is intended for diagnostics, and not day to day monitoring.  As such, some of the values will vary depending on the install.  This is such a case. The WS50...

We are seeing the same voltage and amps at the Battery as we see at the alternator when measuring with your software, but when we actually measure the alternator with an Amp clamp and multimeter we...

This project will require hundreds of hours of work and due to lack of interest, it has been put on hold indefinitely.

Any news on this front ?

Hey Federico, I am not sure what CANBus device you are using will be providing you with individual cell voltages, but if you have a BMS that is CANBus compatible you should be able to find the P...

Nice Job Pete! I was thinking to use the CAN bus data for a High voltage/Low voltage Alarm. The alarm should work when the higher cell is 3,7V or the lower cell is 3,0V. Do you think it would be...

For the  Active BMS (12v) there is a label on the bottom of the unit, attached is a photo from my unit. A detail:   There is a very special way the SN must be entered into the software to ‘unloc...

We are stuck with the active BMS system. Where is the serial number located on the unit, and can you advise us what our serial number is? > > We installed the REC Active BMS but am unable t...

Before I can give you any feedback on this one I need to know, are you using the VSR or the WS500? I am guessing you are using the VSR.  If that is the case, the last supported version of the co...

The OLED is on I2C right off the regulator board.   I created a class structure for holding the formatting information for each data field and some template methods (functions) to accommodate the d...

Because I first implemented the OLED screen using I2C, I ended up not using the serial strings that the system generates and made my own serial strings.  I only output data as the data changes, but...

open source version Is their a community for the open source folks?  Of course, the WS500 config tool first came out for the open source version.  

Those little OLEDs are cheap and the display is amazingly good.  Cool!  Are you using the UNO with the OLED on the i2c and capturing the WS500 serial port data as it gets spit out here too.  Is the...

That\'s pretty handy.  Feel free to share a few pics.  I have considered using an MCP2515 to grab them on the CANBus, then you are not stuck using the serial port. The strings are well documente...

Hey Pete,   Just trying to figure out your MO.  Are you using an old version of the open source VSR code with your WS500, or do you have a current version of the WS500 source code?

I added an off-the-shelf INA226 daughter card with the sense resistor removed and two TVAs added to protect the current sense input.   This provides a second set of voltage and current inputs and a...

I have used an Arduino Uno with a 2.8\" TFT LCD to make a remote display that captures serial data generated already by the regulator (well I could have done it that way, but instead I use my own s...

I am using the open-source firmware and added a .96\" OLED in the case.  This displays Volts, Amps, Temp for both Battery and Alternator, Charging mode, countdown while in warmup and ramp-up, PWM%,...

Does WS500 require #define SYSCAN in order to use System Configuration Editor? I have customized my firmware and don\'t use any CAN functionality so I commented out #define SYSCAN to give me mor...

Hi, Good news on progress!  Tks for the feedback. I have attached an overall screen-shot of the setup on my bench: Frankly, all I did was select the Winston cell items and adjust way down ...

I got it going, not sure what was the trick, did juggle a bit back and forth with the settings again and suddenly i got the green light. Did get the setup as i would like it, but I got a 500/50 ...

Yes, the software has a few details it is very picky about, and I have some ideas. The error you see I am able to reproduce, it seems related to a comms error with the REC BMS its self – not the...
