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...

TMIN - Under-temperature charging disable According to the manual, the charging will be disabled when the temperature reaches the TMIN value. However, I have noticed that the power is also being...

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...

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...
