I have a new 2021 M1 Macbook, running Windows 11 on Parallels.
I need to add a PV inverter assistant to a three phase Multiplus system.
The MK3 USB connected seemlessly with Victron Connect in Apple but no matter what I have tried I cannot get the MK3 USB to be recognised - "Driver is unavailable" by Windows or Ve configure tools.
I have have read numerous community posts and searched Victron information manuals, reinstalled the configure tools, rebooted, updated, set the USB drive, tried through VE Configure 3, tried numerous ports, tried through apple terminal, tried through windows many times and no luck.
The VE config says use the "found new hardware" assistant to specify the location but I can't find such an assitant any where.
How do I get the driver and MK3USB recognised ?????
Greetings. I have two Multiplus 24/1600/40's that I would like to connect in parallel. I have been unable to communicate with them in any way. I've tried a laptop and desktop computer with apple iOS and windows 10 operating systems. I've tried VE Configure 3, and VE The drivers seem to work fine. No yellow triangle, and the device is recognised as an MK3. I've downloaded the drivers both from Victron website and directly from FTDI website. Tried completely wiping everything and starting over several time. The inverters and MK3 were purchased within the past year, just months ago. I've tried everything I can think of and there is absolutely no communication between the MK3 and inverter, nothing, ever. Please HELP!!!
Is the "MK3-USB" interface electrically isolated from the inverter
Using Windows 7 and VE Config: Under special no listing of MK3USB (only MK2USB) , this has been described by several other posters here. Nonethe less, followed Mathias advice: save files, opened them up under device manager but again no MK3USB file to update. Cant use my Victron Multiplus Compact to charge my Victron Lithium batteries (which is mind boggling that the Multiplus doesn't have an easy preprogrammed lithium setting). Any help on this would be greatly appreciated. Thank You.
We loaded VE Configuration Tools; opened VEConfigure3; created a USB directory. The directory only shows a MK2 folder not a MK3 folder. With the MK3 device attached, I do not see the MK3 in Device Manager. There is an Unknown USB Device with a triangle under System Devices - Universal Serial Bus Controller; trying to update it fails with it saying it is the best (but I don't even know if that is the MK3 device to begin with). The Alienware laptop is Windows 11 would that be an issue? Also, my husband did this without the MK3 being hooked up to anything; would that be the issue?
I have searched the forum and seen a bunch of MK3 issues but not this.
I am using a Raspberry Pi setup to connect via MK3-USB to my MulitPlus II.
Now I am looking for a possibility to configure the AC power setpoint via software.
Is there a solution with Venus OS or by direct serial commands as described here: https://www.victronenergy.com/live/ess:ess_mode_2_and_3#using_the_mk3_directly_instead_of_via_gx_device
Or do I really need to buy the CCGX or Venus GX, and if yes, what is it, that makes the functional difference? My Raspberry can already collect all required data (energy meter, battery state).
When reading the RAM IDs from the MultiPlus, no HUB4 Assistant register (i.e. ID=3) is found.
I have a DIY 14.4kwh LiFePO4 battery with an Electrodacus BMS and Charge Controllers. The BMS is able to stop/start charging and stop/start discharging on Victron Inverters. The Multiplus II is the only Victron equipment in my setup other than a MK3 to connect to a computer/cellphone. I'm able to connect to VictronConnect but it doesn't have the ability to program Aux1 or 2 like VEConfigure 3 could. The VEConfigure3 doesn't seem to work with a MK3? What I'm I missing or do I need another $100 dongle to make this work?
I have a little problem.
When I'm connected with VictronConnect on Windows via USB MK3 to my MultiPlus (2609) I can see the MultiPlus, connect to it.
When I do it on my Mac, I get information that it has found a MultiPlus MK3, and I to update.
When I click update, it asks for a password. Can't seem to find it anywhere.
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
Will the MK3 interface work with an iPhone with USB-C and a USB-C to USB adapter?
I am trying to connect a Sony Z3 phone running Android 7.1.1 to a 12/3000 Multiplus inverter using VictronConnect v5.61 with a MK3 USB adapter. VictronConnect starts to search for devices but fails to see the inverter. It finds the BMV700 meter over bluetooth ok.
I know the MK3 USB adapter works as I have used it to connect a Windows 10 laptop using Victron Configure.
Have I missed something
This adapter is left plugged into the inverter all the time - is this OK to do or should it be removed after use.
Hi, i am programming some simple functions on top of the MK3 USB interface. I have read the 'Interfacing with VE Bus MK2 protocol' pdf from the site and i have most of the thinks working. My goal is to implement the AcPowerSetPoint via the MK3 interface.
Does anyone know that the correct MK2/MK3 protocol variable is for setting and getting the AcPowerSetPoint? (aka Grid Setpoint)
When i look at 18.104.22.168 'RAM variables' from the MK2 protocol pdf, i see ID 's 14,15 and 16 and that could be what i am looking for. Unfortunately these ID's don't seem to give the right values.
(Does anyone know the difference between ID 14 and 15? The text is the exactly same for both ID's but they return a different value..)
I have spent way to much time trying to get the V-configure app to run under Parallels on an apple OS X time to move on and buy a machine that will run the V-configure app with out any issues. i will most likely by a used machine with a freash install of a version of the Windows operating system. could some one please tell me a Windows version that they know will work?
Multi 24/5000 went off during running quick VEconfigure and does not appear in VE-bus anymore.
Three units in three phase configuration. Neutrals attached. No load or AC-IN connected. Battery negatives connected first and last rj45. Fuses, contacts, cables swapped and still that one unit is blank. Other two are working normally.
Reset by keeping fuse out 10mins without luck.
Any other ways to reset multi?
I cannot get the MK3 drivers to install on my Windows 10 machine. I have followed every tutorial, downloaded VE Config 3 and created the USB drivers. Tried to manually install them with no luck. Windows says it cannot find the drivers. Yellow triangle will not go away. I have rebooted, restarted, uninstalled, reinstalled. Any ideas? What is the exact filename for the driver?
