@Michael There is an "feature inn" cable on the WS500 for this, its all in the manual. "The Feature-in port allows a wide range of optional capabilities in the WS500 to be selected in real time. T...

It would be nice that be able to set the charge rate like you can do with the Multiplus through the DVCC in the settings of the Cerbo I have a 180A alternator which is charging a 1120Ah LiFePO4 bat...

Looks like Victron has made some changes on their site.  Here's the new link. https://www.victronenergy.com/media/pg/Venus_GX/en/connecting-supported-non-victron-products/wakespeed-ws500-alte...

Tanks for info and how to check. I opend the box and found the ISO1050 at (U5).

I've got two battery banks each is a Nissan Leaf Gen1 repurposed battery. They been up and running for several years now. Recently I add the wifi module that allows me access to a lot more informat...

The Cerbo does not provide battery settings functionality for the BMS.  You can set up alarms, logs and DVCC functionality though

Good Day, This implementation of RS485 appears to be unique in that +VCC / GND is required. Furthermore, when measuring +VCC 5v (pin6) to GND (pin 2) with a DMM this voltage is not as I expected, ...

Does the ABMS show correct current (0 A) when all is disconnected? IS the shunt connected directly to cell 1- pin or via fuse or ON/OFF power switch? What avout the cable from the ABMS to the shunt...

You can open the ABMS and see if there is a ISO1050  (U5) mounted on the PCB. It should be, since we started to put them as a standard from 1-A-0470 onwards.  

I think that is a really good solution. 

If your batteries have No CAN, it is usefull to connect the 2 shunt wires to the shunt at the batteries. But without shunt wire the system will work also. It dont explain, why the system dont cha...

@Michael Thanks.  I switched over to the andriod app and it did the firmware update and configuration download / compare like a charm.  Definitely easier and faster than the Widnows App.

Sorry you are having that problem. It's frustrating. I'm not very familiar with the serial comm driver that the WS500 needs, but it kind of sounds like it's not loading. I didn't have to do anythin...

Hello - I'm having the issue mic outlined.  I did the driver update Trond provided.  After I release the reset button the ws500 tool does nothing.  The green light isn't on.  Wh...

So thanks to those that replied to try to help for my thread: https://ogm-energy.com/community/ogm-user-forum/topic/89665/p-van-opt-2-harness   It was determined that the wrong harness was ...

From said customer: Actually, for a Master - Slave configuration "ERRL?" is required to retrieve the Log array

I was focused on your question about the wiring harness.But assume that that all is correct.Problem you have, stopped after 4 hours.Charging can stop when batteries are full.But the LED on the unit...

Yes the blue is conneccted to a connector post on my Nations alternator (in the photo it has apparently been spliced into a green wire which connects to the post on the alternator).  The large...

Your dipswitches are override at the moment, or by programming, OR after using the ws500 app.  It is set in your logfiles, as override, at profile 8. Profile 7 and 8 are both custom programm...

I didnt have installed this cable myself But blue is field wire, and is normally connected to the alternator. Is the blue connected at alternator? Maybe someone else on the forum have seen or wor...

Ben, many thanks. That sounds like a good explanation. We will deplete the house batteries to below 13.2v tomorrow when we are at dock and then test the alternator charging. I am correct in assumi...

@John Can you post the picture that you talk about. There are different cable harnesen, in lenght and different connectors for different purpose. But color code from the cable have all the same f...

@Jay Explanation:If you connect the usb, the regulator starts up as normal, same way as you apply power to the brown wire.This can explain the difference in behaviour you see, when you plug in t...

I recently had a second alternator installed at the manufacturer.  But this was not thier normal install since it had not been done on my slightly older 2021 Mercedes Sprinter RV. After recie...

I have pushed this back to Tine at REC for his review.  As soon as I hear back I will post it here.

Here is an example captured tonight, the boat is pretty much idle plugged into shore power with an actual current draw of 184W the only loads are just 2 fridges wifi router, and a victron Cerbo tot...

Quick update, when the engines are started up without the USB connection to the WS500, there are no error codes (flashing amber for "slave" mode).  Jay  

Ben, many thanks.  We recorded the WS500 log during two startup scenarios:  1) with solar connected and 2) with solar circuit breakers off.  I don't know how to send the full log fil...

Are your WS500 connected to the Cerbo?   If so, you could also share your VRM, maybe this shows what the problem is.  This in combination with the logfiles gives loads off info.

Can you post a logfile from the ws500 when the engeines are running. Logfile can be made with Laptop and program Putty, see wakespeed manual. Or with a phone and the WS500 app, see wakespeed webs...

We have a Victron/Rec BMS/Wakespeed system that was set up for solar charging but just now hooked up 6 solar panels (2500 watts). The alternator charging system worked fine before the solar panels ...

have had the same thing happen to my system recently suddenly strange ghost loads appearing i had one over noght that too the 4s pack down to what it thought was 8% capacity but the voltage was sat...

From a customer:   Can you assist me in explaining the correct "ERRO?"  Error message retrieval for the BMS System?Using master device address: 16I enter the message string: ERRO?The re...

I have a boat with a REC Active BMS with sn# 1-A-12XX  and want to install a WS500. Can I just update FW to 2.9 and use CAN BUS communication?

@Matthew I have tested a while ago to enter the  RE1L or RE1H in the WIFI module under manual communication. This works great, so I expect it work also with the PC software. Rick, you mentio...

I am using the OEM supplied cable. And, due to the prototype nature of my setup, all cables are short. pristine, and easily inspectable.  I am 100% sure that this is NOT a wiring issue, since ...

So it's no longer programmable using RE1L or RE1H? No WiFi module here
