@Miro I agree with you that a seperated load and charge bus gives extra safety.  If the charging part from the multi, or any datacable fails, AND there is a cell imbalance, one the cell can ...

I have now ordered the wifi module. I had seen your links for the manual and wiring. I can configure relay 2 for UV, and then connect my load bus there. However, I wonder about the parameters: In t...

I am hoping to find someone with the REC ABMS and CerboGX connected via CAN-bus showing the calculation and data for "Remaining Time" given the capacity of their battery bank and real-time amp draw...

Thank you for the quick answer. That helps for understanding.  I think, having seperate relays is a plus for safety. If the CAN fails, I can still use electricity, which is important on a boa...

In older versions you had to have a special software build for a 2 relay system but now with vesion 2.9 firmware , when you have the wifi module you can confgiure your spare relay and opto ouputs t...

I want to wire and use my REC ABMS, using a seperate charge and discharge contactor. I went for the Victron compatible version, have a Cerbo GX. But now I have trouble understanding how to do it, l...

I've got a Tyco 500amp contactor and that takes power to stay closed. I was going to look into bi stable latching relay to reduce standby power when I came across the 7718. This appears to be a sta...

In the task settings, I'm only seeing relay 1 and Opto 2: Is this new feature only available with manual commands? I'm on 2.90-1 of ABMS and 1.61 on hardware 1.2 of the wifi module. Thanks!

from Phil, maye add low battery temp control, with outdoor temp and control relay

Here is a quick pic of a 2.8 and 3.5" screen with a couple of 3D printed enclosures for desk and wall mount. Although a bit more expensive the 320x480 capactive touch screen presents much better. ...

This forum has been started with the intention of having a small group of REC power users provide input and alpha/beta testing of a new ESP32 based LCD TFT capacitive touchscreen display and config...

Stopped the LED flashing when the brown is disconnected? If LED stopped flashing, then IAm afraid the unit is broken. How much amps is the fuse in wire 6?     Best to remove 2 fuse f...

Update - Sorted.  Found a short! Finalizing the install on a 2 engine layout. STBD good, went to port engine and noticed the alternator was warm.  Tested and found the #7 wire (pos excit...

@Trond  Thanks Trond, your setup sounds very simpler to ours, apart from the the fact that you are running dual alternators, nice. I have kept the the original alternator and are using this ...

@Michael We have the 4JH4 54 HK motor with dual 200A alternators. Having one on each side of the motor helps with the side-load issues. Been working great for many years now but we do not use the...

@Trond  Thanks Trond What engine are you using to drive the 400A alternator???? My alternator is water cooled so is happy sitting at 100% more or less full time, and it's running at about 3...

I have the same setup in my boat. 60% field max at normal drive (about 230A). Then 90% when "I need to charge quick mode" (about 400A). Could probably change it to 40%/90%.  

@Trond  Thank you Trond I had totally forgotten about this "Feature-in" cable I will certainly be reading up on this, it will probably be all I need. I will have a play the next time I am o...

@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...

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

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...
