1. Values appear correct.  E.g. REC reports 142.8A while WS reports 151.6A (which is correct based on the DC Loads running). 2.  Gonna hold off on trying that. 3. I'll try this and repo...

ok, lets try a couple of things. First, does your BMS and wakespeed both display the correct amperage readings, or could it be just a shunt scaling issue in the WS500? Second, what happens when y...

I recently installed a dedicated shunt for my 24V Alternator/Wakespeed charging source (CAN connected to Cerbo and BMS). This is on a system with a REC BMS that provides its own battery current dat...

It seems like REC made a mistake by not providing additional relays for Allow-To-Charge, Allow-To-Discharge, Aux, etc to account for none smart devices and critical loads like the Cerbo GX. It w...

Hi Ben I agree, being able to set max charging via DVCC is the best solution, I hope it will be integrated soon. Half power mode is what I use now to regulate power down, it works ok with WS under...

Hello Jhonny, Ben here. Your suggestion from field control through the Cerbo is maybe not the best approach.   But the Cerbo has already a \"max\" amp setting under DVCC which would b...

Thanks Al for your well explained answers. My wish is to be able to regulate charging as needed (0-100%). I am in the process of installing two alternators of 250A each and then it is a big advant...

I had a quick look over your pics.  Nice that you included them.  I see that you have your low voltage hysteresis (deadband) set to what looks like 1 V.  The is the RE1L parameter that Ben is refer...

Without knowing which firmware you are using check the setting from RE1L and CLOW.

This above is with a approximate 20 amp draw. Want to mention this is a SI SMA SETUP.   Batteries in this 16s x 3 config can handle easy 390 amps all day and 3 sec runs at 7800 amp pu...

I\'m trying to clear this bms bug up. Problem is set to low voltage cut off to 2.5v and have tested at 2v and no change from bms still bms shut off at 3.+ volts no matter the change. I have a snaps...

I did bring both these issues up with AL in October 2022. Attached is an photo to illustrate.   The first issue kind of makes sense as the float voltage is defined in the BMS, And ...

Hey Johnny, this is one we will have to push back to Wakespeed for a reply. Copy to Al at Wakespeed @al-thomason

Thanks for your kind words.  We have several more detailed videos in the works too. Think of port forwarding in old land line terms.  It\'s the same as directing an outside line to ring at a cer...

I\'ve managed to connect to my home network in no small part thanks to your excellent video. I\'m embarrassed to admit that I\'m not familiar with \"port forwarding\" but I\'ll look it up and see i...

Sure, the WiFi module can be configured as a AP (Access Point) or STA(Station) device on your home network.  Then you just need to map it in your home router using port forwarding. Here is a tut...

Is it possible? I am grateful to be able to see the status of my power system using Victron\'s VRM portal. Is there anything like that possible with the REC system or are you limited to your home n...

I have an installation with WS, REC bms and Cerbo that works quite well. But there are two challenges I cannot solve. When WS is in slave mode (REC), float mode does not work via \"feature in\" so ...

Hi Matthew, As long as you have a 120 ohm terminator on each of the longest ends, with only short branch stubs you should be fine.  Your best bet is to try and have one continuous cable so remov...

Thanks, I divided the alternator rpm by the engine rpm and added that as the drive ratio value, seems perfectly in sync now. Thanks for the support!

Hey Giorgio,  this is pretty cool.  I havent played with this feature in a couple of years and its great to see it now integrates well.  Thanks for sharing! The engine speed is calculated based ...

Great news! Looks like I didn\'t need any of the above. I was able to get the data to display on my B&G Zeus3 (see attached image). What seems to have fixed was to go into the WS500 configurati...

Thanks for the info Rick, I appreciate the answers! In regards to 3), you mentioned that with a J1939 port I might be able to get the data I want. Unfortunately my plotter (B&G Zeus3) doesn\...

Missed this one.  The IOS app is for offline setup only.  IOS does not allow the use of the port for 3rd party serial USB functions like Android does.  The idea is that you configure it, send ...

Anyone able to answer these? I tried contacting the support but I have not received any answers.

I have to add to my post above that the default low charging temp is -10 C which seems a bit low as my battery supplier said to not charge below 0 I had changed mine to +5 C, but have since changed...

Hi all My charging issue has resolved itself, the last e-mail from Tine said that there was also a temperature feed into the charging rate and that the charging rate is reduced to a 1/3rd of the...

Warranty is 2 years.  Best to contact Rick by email. Iam ws500 dealer in Asia. Iam not sure how they handle a warranty issue as this. If the unit is bench tested all could be ok. Many compani...

Thanks Ben,  really strange yes, two fuses blew now nothing.  I will check the cabling once more but it is in very good condition, zero corrosion and dry. Really appreciate your help.  just in case...

If the blown fuse is not continues happen, it will be difficult to say what \"had\" blown the fuse before.   I never have seen a problem in the WS500 that has blow the fuse.   ...

Good morning.  Test conducted as far as I was able.  The battery bank is 1500 ah at 24v so I wasn\'t able to deplete it however connecting the field and positive resulted in engine loading and curr...

Hi there, I have the above 3 units wired REC -> Cerbo -> WS500 with a terminator at each end. To connect to my NMEA2000 network, would I be right in thinking I would take out the termin...

This is good information Al, thanks for jumping in.  And to confirm yes, REC BMS does support a 48V LFP Victron/WS500 integrated system in both a single SI-Q Series BMS or up to 15 strings of cells...

Ben has some good ideas and I think he is correct in suspecting your alternator is the problem.   Second step after that would be to check the wires inside the AMP connector for chafing.  If neithe...

What is the value from the fuse that is blown? As a test, check or there is a problem inside the alternator. Do this test, which Al Thomason posted in this forum before. \"\"Remove the Blu...
