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...

I\'m having some trouble firing up my REC BMS.  I have it to control a 4P14S Kokam battery pack, and to control a Victron Easysolar 2 GX when it comes to charging.   I have wired up the BMS, checke...

No more over seas shipping costs.  REC BMS\'s are now stocked in the USA

Wakespeed recently released version 2.2.2 firmware update and now the WS500 Configuration app supports these new BMS parameters.  This update continues to enhance the WS500 support for intelligent ...

Where are you located. If in Brisbane Australia then I may be able to help   Andy

Hi, I must be missing something.  I was able to use this to update the firmware on the WS500, but have absolutely no idea how to use this app for profile creation (maybe there is another app for t...

Hi Andy, I am glad your units are working well for you.  The Victron interface is an important part of the WS500 evolution and I believe good progress has been made in that area.  Below I have link...

Has there been any work done on integration into a Victron GX type system. I have 2 WS500 and very happy with them but would like to include them into my Victron System which has an Octo in the mid...

As Rick said, there are indeed two DB-9 connectors on the REC ABMS:  one for Serial access via RS485 for configuration and such, the other for CAN.  To connect the WS500 just connect up the CAN-H a...

Sorry Phil, I just caught this one.  I didnt get flagged as it was just a comment on another post. From what I understand all 3 12v alts feed your house batteries and you have 2 WS500s.  On that...

Paul, I dont have personal experience with REC but it seems there are both an RS485 and CAN bus connection, the CAN being optional.  The RS485 is just a multi drop RS232 connection and is used to c...

Hi Rick & al,   Thanks for your replies. Correct me if I am wrong but the CAN on the REC is terminated with a serial RS485 serial connector and the CAN on the WS500 is terminated wit...

Hi Rick and all, I have a twin power motor yacht with two Caterpillar 3126’s, each rated at 420 hp. One engine has two x 12v 190 amp alternators. The other has one of the same alternators plus a...

Hello,  happy to give more details - and do know we are in the process of creating small \'mini-guides\' to address the details for each of the proofed integrations, until then feel free to ask her...

This a new feature  and I understand that it connects via CANBus to your REC BMS allowing the BMS to issue pullback commands to the alternator, effectively reducing its output if the BMS senses a c...

Hi,   I am just in the process of making a purchase of the WS500 but I would like to know more about the practical details of the integration with the REC Abms as mentioned on the \"Lith...

Hey Laurie, For question 1) The two WS500s should be connected via the RJ45 cable and one of the \"Terminator\" plugs installed in the secondary WS500.  Your existing N2K network can then be ...

I read that WS500 has a reverse engineered NMEA2000 capability and have some questions please. My application is a twin engine sailing catamaran: one alternator on each engine regulated by one W...
