If 183Ah use, SOC should be only ±85%??? 100-(183÷1200x100%)

The Ah use doesn't seem make sense while SOC is 97%, 3% of 1200Ah should be 36Ah instead of 183Ah

I set my battery capacity at the above circled spot on the PC software.  After set up there it still show 800ah on the phone app.

Thank you very much .   Maybe they have specific settings, Zeus connection via Cerbo Can port, settings compatible with REC BMS  

Hi Chris, We sent a REC Active BMS to Arco last fall and they confirmed that it was working but we havent had a chance to test that configuration yet.  I will reach out to them to see if they...

Hello in the topic of Arco Zeus, today I tried to synchronize Zeus with REC Active BMS which manages the entire Victron system via DVCC.Unfortunately, connection (synchronization) failed.Thank you ...

Hey Fred, yes we set it to Li-bmx-ext. I erased and reflashed the update.bin file on the master and it's working now.   Haven't heard back regarding the grid export but I did forward the abo...

@tine As I move the wires around it does go all over the place so fingers crossed it's just the loom. Any chance of getting hold of a spare board and cable to be able to rule out one or other 🙏🫶

R46, R47, L2, C52-C54 are the input filter for the current measurement. maybe you are getting something via burned PCB

That brown mark doesnt look like an issue. Did you ever check the shunt wire pin crimp connections? Remember, you are dealing with millvolts and any poor connection is suseptible to induced galva...

Still pulling my hair out though I think it's the cable..... I have opened up the BMS and have continuity between pin 24 and 25 of the main connector back to R46 and R47 R46 measure resistance of...

did you use the CAPA parameter to change your capacity?Go to the manual commands section in your wifi or PC software and try:   CAPA 1200    <enter> it should respond wi...

I have a REC active BMS on my 800ah Winston cells 2P4S setup.  It's been working great, SOC match my Victron BMS, cell being balance ... However after I upgrade my battery bank to 1200ah, 3P4S...

Delighted to finally bring our WS500 alive under full Victron Lynx Smart BMS /Cerbo GX DVCC Whitespace control.  The 2 year old Cerbo firmware needed updating along with the long awaited 2.5.2...

It is not the matter of code or hardware, otherwise the > 2000 people will send me emails. It may be the thing of wiring and component placement. Like on this picture. See how the battery and th...

The alarm is trigered the same way but only the ERROR LED bliks, error/warrning 7 or error/warrning 5. No sound alarm, no alarm sent over the CAN. I tried to send everything over the CAN bus to Vi...

Also with the 2Q, the alarm for the LOW temp for charging and high BMS temp is silent. 2Q has an aditional algorithm to lower the amount of cells to the most critical, not to step over the BMS max ...

@tine That is interesting, thank you for posting. With the current code, when will the warning be triggered? If I understand you correctly, you are saying that the new code will allow the balanci...

The old CAN protocol for Victron had this eatures for Warrnings. I have mooved this from the code if a lot of ballancing is required the unit heas up. The balancing is reduced near the top end but ...

After Al talked with me about this I reached out to Dragonfly to see if they were interested in working together or providing support for this project, in both Windows and MacOS flavors (maybe linu...

Did you go through Tine's troubleshooting tests above? And verify the pin connections at your AMP connector?

Has anyone come up with a reliable solution to this problem? I went out for a week and can't use or trust the capacity battery percentage anymore. super frustrating!

@Chris Hi Chris. I've planned to use Mahle MG1 48V 100A in my RV, just want to know the connectivity diagram from the WS500 to Mahle MG1. I've summarized the question need your input as following, ...

@Bill this is from Al Thomason, Chief Engineer on the WS500. Upon seeing the forum thread that I sent to him, he replied... ---- Fun!   We never added an external USB socket for two reason...

Ah, I see the time sisnce posting is shown in gray on th4 header bar.

Thanks Rick.  Good idea. Would it be feasible to add a datestamp to Fora postes?  This is a rapidly develooping area and  it would be valuable to be able to calibrate "Just released...

@Adam thanks!

There is not an easy way of coping them, so here are some screenshots:

@Adam can u share your bms settings pls?

@panagiotis So far: nothing. The issue stopped happening. I suspect the cells must be more closely balanced, now.

This will be handy for many customers. Thanks for taking the time to document this hack. :) To maintain IP67 a grommet might do the trick.  I always kept this cheap little kit onboard. https...

I note others have encouraged Wakespeed to incorporation an accessable usb port for the WS500 to take ongoing advantage of the phenomenal OGM WS500 Configuration and Dashboard tool. So I sourced a...

@Adam hi what did you do so far?

Hi Trevor,  Did you go through the quick start guide when you setup and select the Li-bms-ext setting on the Sunny Islands? Also have you adjusted the parameters on the BMS to match to the SM...

Since we're talking SMA, I'm going to follow this up with some comms issues with another system. 2Q BMS, 1.4 and 1.6.3 FW. We verified the battery communicated with our shop system (2x 6048-US-10,...

@Christopher , The max charge, float setting en recharge settings is just one example to get the system running. You can change this settings to the settings you like yourself.

@Ben Everything works very well.Thank you .

I can't ever rember a Master failing so we have never had one apart.   Grab a Torx#10 and slide off the cover.  If its like the BMS's look for a small black/brown approximately 1cm s...

Hi,  Have a Master BMS were the external fuse was blowed. Now the BMS will not start up. Is there any fuse inside the unit? Power supply is 48 V in to BMS.
