My answer was ONLY focus on your question to solve unstable float voltage. Therefore I copied the standard firefly profile. Copied completely from the pdf. But only this lines are the charge p...

Trying to fix a problem where the amps are going over 105 which triggers the bms cutoff and a constant start stop cycle of charging, if I put a load on the system it never cycles, reading the confi...

As to Max A in Float, 5 A is the default in the tool.

Looks like there is an added field in CPB to set max V with 2.5 but it isnt adjustable in the config tool, or at least I cant find it.

  can only study exactly what goes wrong, when you post a full log, and point to the exact time where something goes wrong. Ok. Will do next time. I used excerpts to reduce the pages ...

If you use the graph on the first page of the ws500 config tool you can click on any one of the 4 chart inputs on the left and display any parameter coming from the AST string.  I would suggest add...

Its probably caused by the BMS, but we cant tell by looking at that graph. I believe you can get the \"max charge current\" graph from the BMS up there as well. A-BMS FW 2.8  and WS500 FW2.5 ...

I can only study exactly what goes wrong, when you post a full log, and point to the exact time where something goes wrong. At your posted log, I see, regulator goes in float, and go to 0% field...

Hi all Any idea why my alternator output would pulse??? Dropping the current from 100A to 60A and then back up to 100A. I have current set the max charge current to 100A until I get some new ...

Just finished a long run down the coast. Issue I am having is WS500 sometimes transitions to correct target FloatV with steady Field% and at other times tries to hold a lower V, with constantly var...

You could get the REC WIFI module.   Would be cool if you could download and upload config over VRM for Wakespeed. Should be easy to integrate, but I doubt that will happen. I know...

If you charge relatively high amps compare to battery bank, amps sense is more important. If you can charge the bank at float voltage, probably your float voltage is set too high. Do you set ...

I\'m a MAC OS guy too and this has been a major drag, a major annoyance. The only Windows s..t I still have to look at on my boat  is for my REC-BMS and the WS-500. And I do that through a little I...

Done. thanks!

Hi Rick, can you please remove \"MAC OS\" from the \"additional info\" of the software please? I got fooled by this and wasted a Download into my Mac. Luckily I also have a Windows laptop which I c...

Victron has just released some great documentation on its integration with the Wakespeed WS500 Smart Regulator. https://www.victronenergy.com/media/pg/Cerbo_GX/en/wakespeed-ws500-support.html ...

I guess the biggest drawback is the WS500 will go from Bulk to float the second the battery hits 14.2V. How much effect this will have i guess also depends on the battery and alternator size. ...

Pb batts need adsord LiFe does not and can be largely sensed by the \"knee\" Therefore, is there significant value in tracking battery current? Solar is mostly voltage tracked. With a once a d...

Hello Michael Allo, \"\"Zero amp mode\"\" is something different as switching the alternator off. \"\"Zero amp mode\"\" means the alternator just produce the the amps to keep the shunt at zero ...

Quote from Hans Johnson on September 5, 2022, 12:45 am It would be great if there was a way to add what amounts to a second \"Feature-In\" port on the WS500. I use the Feature-In to limit the f...

In half power mode, it is very very rare, you need the temperature sensor for protection. Almost 100% sure it is not needed. As usual, test at time off installation, how the alternator temper...

Yeah, I was aware of the \"short out the temperature probe\" thing, but I was trying to have my cake and eat it too. :) If you short out the temperature probe, the system can no longer monitor the ...

Hi, thanks for all the help last week, I now have a working unit which is great news, including the tacho reading. I was getting a full output from the alternator when the battery was around 70-...

My battery is a 2p4s built from 230Ah cells. When at the dock, I set the Victron DVCC level to 13.3v for storage. If I\'m heading out for anything more than a day sail, I\'ll remote in the day befo...

Hello Hans, I need to check where the below information in in the manual, but it is from my personal notes. There is another way to force the regulator in halfpower (50%) mode.  Then you \"\"...

It would be great if there was a way to add what amounts to a second \"Feature-In\" port on the WS500. I use the Feature-In to limit the field drive to 50% (big alternator on a small motor). It\...

your blog 2 september: 1. read as normalized 12V and read as normalized 500ampH 2. There is no reason to discharge the batteries to test exit amps. I f battery is full, normal behavior will ...

Yep, I probably asked the MS tech the wrong question. The MS CAN bus output is digital but I could have wired directly. Just checked the current measured by the WS and it agrees with the MS shunt. ...

You can connect an Masterbus shunt to an WS500 if you want. Shunt is between negative input and output in the  Mastervolt shunt. Just connecto the WS500 shunt terminals to these two posts and...

would have been sweet to use the same shunt but the MS shunt converts to a digital message and no way to get at the shunt itself. Thanks

Understood. I thought maybe you used the Mastershunt as an shunt for the WS500.  

Thanks, I am reading tail current from Mastervolt closed loop network on the Mastervolt remote display so I am assuming the battery current I am reading is correct, although I have never measure...

I belive the Mastervolt Mastershunt 500 is 300A/50mv. You would think its 500A/50mv, but its not.  

Thanks Ben, Bat Cap Multiplier. Lots of places in the WS manuals where it says system is designed around a normalized 12v system. I was over-applying that logic and assuming the A were normali...
