Conection to Multiplus with MK3-USB not possibile

Hey Guys,


I can´t connect to my Multiplus 12/1200/50 I followed the instruction of the victron videoI found here, https://www.youtube.com/watch?v=6lH3mF2cVaY&t=6s I tried using both a mac and a win 10 laptop, both with the same result, that the Victron connect or VEConfig app won´t go beyond the point “fetching data from VE-Bus” and then times out. I double checked the drivers in windows and COM port 7 uses FTDI driveres I also tried the VE Config app with “auto detect port” and manualy selected both com3 and COM7” with the same result that it can´t connect. If I go to force connect it times out as well.

If I use a Color Control on the VE-Bus port the Multiplus is recognized but I can´t really change any setting or setup an ECC.


From the Color Control I see the following firmware details of the Multiplus.


Productcode:2662

Fimrware 416

Device Instanz: 257

VE.BUS Version: 2662416

MK2 Device MK3

MK2 version 1170207


Any help on how to properly connect would be very much appreciated!

Thanks for your support.

Multiplus 12/2000 will not connect to laptop with MK3

I installed a 12/2000 Multiplus compact in my travel trailer with 100ah Battleborn batteries. I am having two issues.


1) The Multi will not connect to neither of my two laptops using two separate MK3’s. The RJ45 cable I am using is from Victron and connects to my Smart Dongle without any issues. I need to program my Multi with the laptop as it has not been yet. This is making me feel like I wasted a lot of money of it.


2) When I am plugged into 30A shore power, the Multi will not let me use shore power for large loads (starting my AC) and it tries to do all of the work. My smart dongle then reads that it overloaded and the Multi shuts off and then back on. When plugged into shore power, this shouldn’t happen. It should just pass the power through (even power boost if needed) but it does not.

Previous posts have not been helpful with resolving this.

So far very frustrated with Victron products and will be selling this on EBay if it can’t be resolved.

Which old Multiplus are compatible with MK3-USB

Hi,

I just bought an older Multiplus Compact 12/800/35-16. Before I buy the rather expensive MK3-USB (VE.Bus to USB) Interface I'd like to know if my Multiplus can connect to the computer, because I heard, that with old models it isn't posible.

That's the lable. Anyone able to answer my question?

Thanks a lot,

Why can’t I use Bluetooth instead of MK3 to change settings on VE.Bus Devices

@Guy Stewart (Victron Community Manager) , I've been trying to find a post on this forum that explains why we cannot use VictronConnect / VE.Bus Smart Bluetooth Dongle to configure VE.Bus devices.

I imagine that Multis and the like are among Victron's best selling devices. Why would Victron not make at least a basic quick configure available through VictronConnect via Bluetooth for them?

I think I read once (perhaps from @mvader (Victron Energy Staff) somewhere) that this is a constraint that stems from the design of VE.Bus vs VE.Direct but I don't understand the details beyond that.

Interested. It is a real PITA having to use MK3 on installs. I am a Mac User and this means VirtualBox and Windows and taking my Mac onto sites. It is seriously schleppy.

It would be ideal to be able to use VictronConnect via Bluetooth on my iPhone instead.

Problem with connecting to Multiplus 12/3000/120 with MK3-USB using VE Configure 3

Hello everybody,

I connected to my Victron Multiplus 12/3000 via Windows 10 PC and MK3-USB interface with VE Configure 3 and only made adjustments (absorption voltage, charging curve) on the "Charger" tab. Then I sent these settings to the Multiplus and saved them. So far so good.

After this I did chose the "Show Panel" option from the "Target" menu. The panel appeared briefly, then the connection to the multiplus was broken.

Since then it is no longer possible to establish a connection to the Multiplus via PC and MK3 USB interface with VEConfig. During the connection establishment (bar runs through) the process aborts every time and my Multiplus switches off. I can switch the Multiplus on again by using the Cerbo GX console or VictronConnect App with Bluetooth. After switching on, the input current limit is always set to 3 A (normally set to 16 A).

With the VictronConnect software, the Multiplus can be easily reached via Bluetooth as well as via PC and MK3-USB interface. The Multiplus also works flawlessly.

Does anyone have an idea how to solve the problem?


Greetings
Matthias


By the way:
A similar phenomenon I had before, when I first started up the Multiplus months ago. Back then I tried around and activated the AES search mode. (with the current problem described above concearning AES mode nothing was changed.) Immediately after activation, the connection was broken and I could no longer establish a connection. At that time I canceled the setting via VictronConnect (PC and MK3-USB interface), then it worked again.

Any special tricks for using a Mk3 on a multiplus that is linked to BYD batteries via Venus GX?

I have a Multiplus 2624 on firmware 431 connected to a Venus GX and some BYD batteries. When I want to change the input current limit I can do this using VRM>device list>download file>VEconfigure>save file etc but a few weeks ago I got an on-the-go adapter for my Mk3 interface and used VictronConnect to access the Multiplus settings really quickly and make changes using my Android phone. This was so much easier, but when I tried to do it again yesterday the Multiplus would not show up on VictronConnect nor could I connect with it using VEconfig on my laptop and eventually the Multiplus shut down because it could not see the Venus and I had to go back to the old way.

My question is what went wrong? The Mk3 works well normally. I unplugged the VEbus from the Venus GX and plugged it into the Mk3 and went looking for the multiplus but it's not there. Wondering how to make that work like it did before. Any suggestions? If you tell me to update the Multiplus firmware then I ask how, without a Mk3 connection?

Thanks for any wisdom.

When two 48/5000 inverters in parallel, to switch them off remotely is it enough to switch off the Master?

Maybe I'm just not attent enough but couldn't find in the manual if both parallel units' remote connections shall be wired to switch them off, or is it enough to wire the miniBMS with the Inverting on-off cable just to the Master? If both shall be wired can I use the same Inverting on-off for both (it support max. 30mA) or shall I use two cables in parallel? Also, in this latter case will the miniBMS support the double current draw?

At startup the software will tell me to Disconnect all accessorries when using VEConfigure 3 . In my setup I have to disconnect my CCGX .

Do I have to disconnect only the Power from the CCGX or do I have to disconnect the Ve.Bus cable from the CCGX?

MK3 USB 'S' (State) command does not change panel switch state

Hi everyone,

I implemented the VE.Bus/MK2 protocol following "Whitepaper-Data-communication-with-Victron-Energy-products_EN.pdf" and using a MK2 USB device. All commands and functions work as described.

However switching over to an MK3 USB device, the three Quattros i'm testing with do not react to command 'S' as expected. Using the same commands, the MK2 does the job.

The whitepaper mentions certain jumper settings in the MK2 (which i never touched, the S command worked with a standard MK2 device) however when I opened the MK3 device there were no jumpers inside to play around with.

I have not seen any mention in the whitepaper regarding this. Is there a specific command to issue or a flag I need to set in the MK3 for this command to work properly?

Thank you forward for any responses!

Update firmware or configure via USB an old Phoenix multiplus compact 12/2000/80

Hello guy's

I've got an issue with an old Phoenix Multiplus compact 12/2000/80 on firmware 1871148.hex ...

My problem is that the value for the low level battery is at 12.4v and it turn off inverter at 12.3V ...

And the second issue is that the charger don't want to be turned on even if its plugged on a generator ( i try 1000w and 2000w generator) and not even when i plug it on the grid ... when i turn the multiplus on charger only i can hear a "Clac" in it, but doesn't work anyway ...

So i almost buy the MK3 Pc ve.bus to change the settings and maybe see if the problem came with some wrong value in it =)

But i read on some victron page that this 1871148 firmware has no Ve.bus (and my pcm have only one rs485 connector that proove that my multiplus has no Ve.Bus)

So can i upagrade it any way ? the Mk3 can work or maybe i read somewhere that i can try with the old Mk2 ? but its a lil bit expansive and i can't buy the two just for a try ^^'

Do you have some ideas why the charger dont want to turn on even on the grid ? or ideas for the limit value of the inverter ?

Thanx for helping me guys and sorry for my approximate english, i'm french ! ;)

Unable to connect with Multiplus via MK3 USB

Hi

I am installing a system using Multiplus charger/inverter. I need to configure the Multi. Hence communication between PC (Lenovo Win10) and Multi is required.

I have installed the VE configure III and I have a MK3 USB interface.

When I let the VE Config auto detect nothing happens i.e. the programme is doing a search and eventually times out.

When I try manual connection to e.g. Com3 an error message apperas saying "Cannot open Com3" - it does not help to change Com port no.

I have removed and re-installed the MK3 driver. In device manager I am able to locate the virtual serial port i.e. that part seems to work fine.

I have also tried to use the VE Bus Quick Configure software - and the error is the same

Any good suggestions?

p.s. I have tried on a different Multi and the error message is still the same. I have not tried a different PC yet - not so easy due to remote location

Older Phoenix inverter 24/2500 readout VenusOS

I know all the recent models of this inverter/multiplus have ve.bus possibilities and I know my current one does have this phone/ethernet like port.

I'm now in the process of setting up VenusOS on a raspberry to read out the MPPT charge controller but can I also connect to this older inverter? It's a Phoenix Inverter without the orange stripes but with the red phoenix bird.

My guess is it can be done with the MK3-USB interface but I'd like to have a confirmation on this and if it's possible, what kind of information can I pull from the inverter? If not possible, any other ways to pull status information from this device?

Two Bus systems with one CCGX - problem

Hello Everyone,


I have a system with two VE BUS systems. In total, I have 3 Quattro. Two of them are connected in parallel and connected to the VE BUS port. One I connected through MK3 to Color Control.

I have two problems:

1. I can see all products in Color Control, but if I want to come back from Quattro with MK3 I need to do reboot, is it normal?

2. If I have the Color control off from the power supply and I want to turn on the Quattro it does not react.
I have to disconnect the VE BUS to turn on the CCGX, plug in the VE BUS and then it works again.


In my opinion, this is not normal. When the Color Control is turned off, Quattros should work, it is a system on the boat.

Maybe one of you had a problem like that. I will be grateful for your help.

Earthing and Solid Red Alarm EasySolar 12/1600 MPPT 100 / 50

Hi All,

We purchased an Easy Solar

12/1600 MPPT 100 / 50

We installed it in a caravan with two 230amp Victron super cycle AGM batteries.

We are having issues getting the system to operate. The red alarm is staying on all the time. We commissioned it using the dip switches as per the manual. Will it only function if we commission it with the MK3 tool ?

I am getting conflicting information on what it could be.

AC input voltage is correct. We have no AC voltage on the output side ( inverter charger )

Battery Voltage is low 11.9v but the MPPT solar charger is not functioning. The light is staying on bulk but we have over 28v charge from the solar.

We have been trouble shooting the installation by removing the AC input, making sure the Victron is the MEN ( should the Victron be earthed to the van ? )

We also removed the DC solar / MC4s from the MPPT.

The van was originally wired up with 12v circuits to the batteries, these have just been re connected.

If anyone can help it would be greatly appreciated, the dealer we purchased it through don’t have any technical knowledge when it comes to electrical.

Cheers

Dan
