@nebulight Where did you find the 1.61 firmware on the "main site"?

The problem persists.  I've verified all connections, verified that the WS500 is reading the shunt correctly. I haven't heard any response here or in other forums. How do I get support for t...

@Mike Our boat has been in storage for the past few months and so I've let this issue lie.  We're back on the water in a week or two and I then plan to push to understand what is going on...

I am going to include Al fromWakespeed in this thread and see if he can provide any insight. @Al Thomason  @Rick Admin 

I have exactly the same problem and I know I am not alone. I am concerned about the effects that this fluctuation/spiking will have on all the powered devices. Surely it can not be dismissed as "no...

@Michael Thanks Michael. I am a little gunshy due to probems with the system over the last several months. I am regaining confidence in it. I had alternator issues that nobody was able to diag...

@Brent The idea of the BMS is to control the regulator, and will override your settings, as Al is pointing out that one of the points of CAN bus communications is if the cells are getting out of b...

at Carl Dewever: \"\"hello, thx for that info, however, where can I find that kind of info? It looks like I\'m missing some documentation... can I program these 2 parameters with the wifi-modu...

@Al Thanks Al. I have the REC BMS but the regulator is temporarily disconnected to establish a configuration that would work without the BMS. The regulator will be reconnected to the CANBUS sh...

@Michael Thanks. I am going to raise the float voltage to see if that resolvese the issue. the 13.0 value was from the default LiFePO4 profile. 

@Brent (Disclaimer:  Al of Wakespeed). As suggested by Michael, it sounds like the float voltage needs to be adjusted.  But am a bit more concerned by:      "I have ...

Hello.  (Disclamer:  Al of Wakespeed). I am not an expert here, but I think you might (guessing here) be seeing some odd things on the main Cerbo screen, as from waht I understand the Ce...

Brent  One thing that caught me connecting the REC to the Wakespeed is the data cable is not a straight through cable and so you need to make sure you get the pins correct there are only two ...

Brent It sounds like your SOC is dropping because your "float" voltage is set to low (I assume your "revert" voltage is the "float" voltage)? By setting your "float" voltage at 13V the regulator i...

Guys, after talking with Al, he confirmed that the WS500 does not integrate with CVCC yet. From Al \"And at all times the WS500 directly takes its guidance from the BMS -- Victron has not extend...

I would think you only need 2.9-2 if you have an older system and do not have the Wifi module

No, its a setup screen in the \"Tasks\" tab of the WiFi module, with several parameters and alarms that can be configured

Rick, thank you - can it be done without WiFi module?

As per my other post you will likely find what you need using the Tasks feature in the WiFi module.  I would use an opto output as your charger interlock and set it up in Tasks while the relay is u...

I have a general observation to share. After installing firmware v2.9, we discovered that negative values for Opto(x) CH Hysterisis (OPxH) are no longer supported. Although the system allows for ne...

Yes, all parameters are programmable by either the PC software or the Wifi.  The only difference is that with the new firmware there is a new feature called Tasks that also allows custom configurat...

The charge relay is controlled with command RE1L and RE1H.   Not with CMAX.

Hey Nathaniel, I see you posted this to the Victron Venus github project as well.  I also just reached out to Al at Wakespeed to see if he could offer any insight. 

Missed that one.  Getting the details and hope to have it posted in the next few days Thanks for the heads up

I see the firmware on their main site, but not the NA site. Any idea what the new firmware addresses? Thanks!

I have a WS500, Balmar XT250 and 840Ah LiFePO4 battery on my sailboat. I have a REC BMS, but it is NOT configured to control the WS500. For now I want to have the WS charge independently. If I have...

@Rick Admin  Verified that the KW to the battery is correct with "DC System Off", but the battery KW was always correct.  It was the DC Power reported in the DC block that was wrong.&nbs...

Following up on this in case someone else has the same question. I was able to get this to work by getting an ethernet cable, cutting off the end and attaching a nmea2000 field connector. Wir...

Yes back to coffee ☕️ in the morning. Sweet Rick that fixed the problem. RAZL 0.25 RAZL? SHOWED .1   Please re-up voltage perimeters control chart. Shows error when trying to ...

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...
