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...

100% SOC progress With latest config was able to see ACC to Float at 5A. Very close to target. If Ben is out there, I attached an excerpt of the log. Thanks for the suggestion of running the tes...

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...

point 3: There is not written in the manual todo any calculation to a 12V/500Ah Battery, I dont know from where you had this info. In de manual from Wakespeed is written: \"Which Battery Capac...

Yes, probably your cable is meant for connection to Victron, but we dont know that. You can see that by looking at the RJ45 connector. Is there cables on PIN 7 and 8? Or is there cables on...

Configuration and even more monitoring thru the Victron VRM system would be optimal. Download and upload of config file. But I guess that would be a bit optimistic.

I hear you.  Our Windows app was originally designed for BT support but I understand they couldn\'t get it to be reliable.  If they do, most of the code is already roughed in.  I hear they are work...

Ben, Much appreciate the detailed response. Here is where I am: just updated firmware to latest rev I will deactivate Overcharge altogether. I had to read up on Finish Charge to understand....

Michael,   Trond makes a good point here.  Wakespeed uses a different pinout than most devices such REC and Victron so you need to be careful as if you were to connect a standard Etherne...

Hey Rich, I am guessing that might be to power the RS485 to USB in the custom programming circuitry but you would need to contact REC directly to confirm.  On that note your programming software in...

I would like to connect a PC to the Active BMS using a USB-to-RS485 adaptor.  As a first step I examined the pin assignments for the DB9 connector.  These are shown on Table 5 in the user manual. ...

thanks, I should have rephrased all that about the alternators. My guess is, they are putting in as much as the batteries will accept. About the same current as when I engage my 3X chargers. (300A)...

Thanks for your quick replies.  Using the Oil pressure sensor is not an option because a real failure would then also \"activate\" the charge lamp giving the alarm system the same state as if the e...

Thanks Al, I will upgrade the sw today.
