I have multiplus 40/3000 and my old FW is:
2620158 i believe i need 2620159 with im trying to update.
But having error.
I dont have problem to VeConfig, Victron Connect does not work becouse my FW is to old.
Swapped device, changed ports and all... still no luck.
Tried to google solution but cant find any,
I want to update FW and go with Generator configuration as every 60 sec there is a swap between charger to inverter.
I've tried another ethernet port and no luck still.
I'm under off grid so I only has batteries connected.
Please see the attached unlisted Youtube video.
Basically when I plug the ethernet cable in to the MK3 the inverter faults, unplug the cable from the MK3 it will recover ~20 seconds later. I've ensured the cable is not faulty, tried a few different ones, all none crossover.
When I first plugged the MK3 usb cable into the computer and ran VEConfigure3 the software found it no problem and asked to update the firmware which was successful.
Unfortunately I lost the top part of the case from my MK3 interface.
The interface is still fully functional but like this it is vulnerable.
It is somewhere in the bilge of a large ship under the motor, not able to find it there.
So if someone has a defective MK3 lying around I would be helped.
Any other cheap solution is welcome.
I suppose Victron is not able to deliver an empty case...
I'm starting to regret buying a Multiplus II as setting it up is proving impossible.
The Mk3 adaptor is working fine as it feeds data to a raspberry pi.
I run Linux, which Victron don't support, but I have an old Windows XP laptop which will run the software. However it will not connect to the Mk3. I have followed all the instructions multiple times. The download driver from the internet does not work. The one that VE config provides does not work. Does anyone know of a driver that does work with XP and where I can get it ?
It is a shame the Multiplus is so difficult to setup, the other kit is all very simple via bluetooth. Having various bits of software which half do the job is a complete waste of time. Victron need one cross platform program that will deal with everything, and built in bluetooth for the Multiplius, it costs enough...
Is there a site which explains how to upgrade and connect two multis in parallel using the mk3 ?
Every time I install the MK3-USB driver it becomes unavailable again in on a few seconds. Then i have to remove device, unplug it, replug and try again. Dozens of times, no luck.
Hello, i want to set the Victron Multiplus 24/1600/50 inverter or charger current with the mk3 usb interface. i read the VE.MK2 protocoll but it is not clear for me how to do.
i tryed to create a 'S' command, but it do not work.
if i switch the inverter with the switch on the inverter to inverter mode it starts to invert full power.
i do not know why?
i tryed the command
07 FF 53 02 03 05 01 01 9B -> answer is OK
but nothing happens.
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
Connecting the MK3 to USB cable to the USB port on my computer causes the computer to reboot. It will continue this reboot cycle until the MK3 to USB is removed. Any other USB cable plugged into the computer does not cause this problem.
Is an MK3 interface the same as an USB 3.0 to RJ45 interface?
The USB 3.0 interface communicates but there is no communication with my Multiplus Compact 12/800/35.
Multiple previous connections using VictronConnect on Win 10 using MK3 to my Multiplus. Upon launch of VictronConnect application today it auto upgraded to v5.45, now I am unable to connect to my Multiplus. Verified proper wiring, connections, and MK3-USB is active on COM3 in Windows 10 device manager. NO other changes on the PC that I had previous connection success with. Force Connection also does not work.
I am familiar with VictronConnect on bluetooth and Android - no problems there.
Today I purchased MK3-USB interface, installed VictronConnect 5.42 on laptop and desktop PCs, tried 2 brand new LAN cables to connect to new Multiplus 12|500|200 (which is powered on). VictronConnect simply reports "No devices found"
Have tried different computers and cables, reinstalled VictronConnect, turned firewall off, run as administrator. But result always the same, after a few seconds of searching: No devices found
What else can I try?
I can't get my Multiplus to be recognized in VEConfigure. I've got an MK3-USB, dowloaded the drivers, restarted the computer, reinstalled VEconfigure. My USB drivers are working OK, computer is fine, but for whatever reason I can't get my Multiplus recognized on VEConfigure3. It also won't show up on VictronConnect.
My CerboGX and Touch50 recognize the Multiplus just fine. What else can I do to adjust the parameters of my Multiplus?
I need to adjust some setting on the multiplus for my pylontech batteries.
Ich möchte mein multiplus 12v 2000 mit der HQ2101 gerne konfigurieren. Der multiplus ist über AC angeschaltet. Nun findet das Mk3 Dongle aber das Gerät nicht und ich habe nur die Möglichkeit zur automatischen Port Auswahl. Was mache ich falsch?
With two installers at site, two laptops, two MK3's (both with moulded in cables) both can connect to the Mulitplus-II GX with VictronConnect. But when they close VictronConnect and open VE Config (to set up PV Support assistant) they cant connect. They get 'Help on Connection' notification, etc, Have tried downloading drivers, running Prolific_DriverInstaller , etc etc but no change. (have also tried setting up via VRM but limited connection at site)
I have a 15KVA Quattro running ESS Assistant and set to use 60% of battery capacity for self consumption (Optimised without battery life).
I am looking to switch off/disconnect the AC output at 30% SoC in case of grid failure/load shedding/poor quality mains supply using assistants ( I understand from the ESS manual that the settings in the Ve Configure 'Inverter' tab for DC low voltage shutdown and shutdown on SoC are completely ignored while running ESS.
In the VeConfigure assistants page, I have set after the ESS assistant;
1) Programmable Relay (Drive on SoC), set 'Primary Programmable Relay' ON when SoC at 30%
2) Safety switch assistant set to switch off when the Aux 1 relay is set to ON.
3) Programmable Relay (Drive on SoC) to set Aux 1 back to OFF when SOC at 35%
I have written the assistants but nothing happens when SoC gets to 30%, the inverter keeps going and drains the battery beyond my desired setpoint.
I understand there is some additional physical wiring to be done for the safety switch to work - I have three questions.
1) Are the Primary Programmable Relay and Auxilliary Input 1 thesame?
2) If they are thesame is it safe to short the + and - on the Auxilliary input 1 without damaging the inverter?
3) Can anyone please help identify the specific physical contacts/safety switch connection points to use on a 15KVA Quattro and how to wire it up correctly?
I have a solar kit I bought recently with a Multiplus 48/5000/70 and a SmartSolar 250/100. The system has a CerboGX and Touch 50. The battery bank is 4 Pylontech US3000.
I was reading the Victron-Pylontech compatibility article, and just watched a webinar on the topic, but I'm still unclear.
To make sure all my Victron components are configured properly according to what the batteries need, can I just use the VictronConnect app via my smartphone? Does this operate via some sort of bluetooth connection internal to the CerboGX?
Or do I need to buy the Smart Dongle or MK3 USB separately?
Doesn't the CerboGX and Touch50 replace the need for the VictronConnect app or at least replace the need for the SmartDongle/MK3-USB?
In my boat I’ve got a Multiplus since 2013 (former owner placed it). I don’t think it has ever been updated. But now I want to connect it to a Cerbo which I bought recently: do I have to update the firmware of the Multiplus? I understood I have to buy a MK3-dongle then and it’s a waste of money when not necessary.
Please your advise.
New install in an RV with lithium batteries, all lights were on and working. Inverter was working properly. I got a MK3 dongle to be able to program the charge parameters for the lithium battery bank, and after doing so and updating all firmware and uploading settings, now I have no lights in the Multiplus and the inverter won't power up. Voltage measured at the terminals on the inverter checks out good. I suspect that my computer is being recognized as a virtual switch and it is waiting for a signal to power on, but now I can't connect to the inverter because it is off. Is there a way to do a "hard reset" or "trick" the unit into turning on?
I try-out to communicatie with a multiplus 12/3000 by a mk3 interface connected to my chromebook. The multiplus want show up in victron connect.
Last week i treed to connect a multiplus compact 12 /1600 by a ve-direct to usb connected to my chromebook. The multiplus dient show up in victron connect.
Is the mk3 compatible with chromebook?
Thanks in afvangen
Kind regards, Piet
Ok...finally got hold of a windows laptop. (Apple not working - no workarounds etc...)
Q1 - Do we 100% need the Victron MK3-USB in which to connect and use VEcConfigure?
Q2 -can you use VEConfigure via wifi??
Q3 - are there any other cables I need?
I've downloaded the Mac VictronConnect app on the Victron website, but it doesn't see my Multiplus, even while I'm connected using the MK3 USB. All other discussion here discusses using Wine or Parallels, yet there is a Mac app on the site for this purpose. Anyone have any luck using the app and seeing their device?
Although I have in the past been able to connect just fine, after a remote panel firmware upgrade I am now unable to get past the loading data in victron connect or any other app. Seems the mk-3 is connected but cannot find the multiplus. I have tried Uninstaling the apps and drivers, and have used a second pc and dongle.
When I switch off the MultiPlus 12/3000/120-50 with firmware 413 with my Venus Gx Remote Console with firmware 2.60, I can't switch it back on.
The workaround is to disconnect the network cable on the MultiPlus and reconnect it again.
This should be a known issue because I got the workaround by one of your installers.
My question is: Can VictronEnergy do something to fix the issue?
Thanks and regards,
I've been trying to configure a parallel system with 2x Multi Compact 12/2000/80.
But cannot communicate at all with one particular unit. I've been able to configure the other unit using a MK3-USB & Victron Connect software. I was able to update the firmware to 2608481.
I cannot connect to the other using the same setup (pc, patch cable, MK3, Connect software.) In connect it recognizes the MK3 and tries to retrieve the data from the multi - this fails to connect and the "Force Detection" button also fails to connect.
I have tried VE.Config to connect but this also fails. I have downloaded the firmware and also tried to force it to update using VE.Flash & this fails to connect as well. - As far as I am aware the firmware currently on the unit is 2608430.
I tried to use VE. Bus Quick configure to setup the parallel system, the program recognized the first unit as the master, recognized the second unit as the slave but was not successful because of the difference in firmware. Any ideas on where I can get version 2608430 would be helpful, then I can try VE. Bus quick configure with matching firmware numbers.
To ensure the equipment was not at fault I have now managed to try 4 different PC's & several different patch cables.
I'm resisting having to take the unit out and returning to the supplier until I know I've done everything possible.
Any help/things I haven't thought of would be appreciated.
Hi everybody ! Lately I am reading comments regarding "overpriced" hardware from Victron, and in many comments we can see examples of cheaper alternatives. Ok, but people if there is a higher price, it might be a reason.
Usually, when you buy a branded product from a valuable company, you get SUPPORT, WARRANTY and SERVICES. This has a cost, and it is also calculated in the final price.
I'll tell you my story : I created from A to Z my installation, buying cheaper components from Chinese products. They were working fine (Inverter with integrated MPPT), but it was no way to perform equalization. Then, I bought two MPPTs from the same brand, supposedly being able to be paired and providing enough energy to equalize my battery bank. The problem is they were not correctly fine tuned and the voltage was different from what my Fluke Meter was measuring. I had a serious fight with the seller, and finally the manufacturer connected on my PC remotely to fine tune the MPPTs. Unfortunately, my battery bank was already damaged (sulfation).
I decided to buy the Smartsolar 150/100 MC4 with screen, and since, no more problems with the battery banks (I still use the "damaged one"), but had also to buy new batteries. I spent 8 months with the Tech.Support from the battery manufacturer trying to fix them, and at a point I recovered part of them.
Conclusion : some cheaper solutions do work, some others don't ! If I consider the time spent trying to find a solution, the costs of the "unadapted hardware", the damaged battery bank, it would have been better buying from the start a brand with a serious tech. support. Unfortunately, when I designed my RE Solution, I had not all the needed money, nor the knowledge I have today.
So, better wait to have the financial ressources and buying branded products, than a cheaper solution that will cost you a lot more within a year !
My two cents..
I have been following the community post on this topic and it looks like that option was being developed. Is it available today? I currently only use a Mac.
my mk3-usb connection with either Mac or RPI venusos is very unstable. I have tried several RJ45 cables but no changes and even bought an original from Victron. Do You guys experience the same issues?
What is the difference between MK2 and MK3 interface? I have one MK2 now. Will I get stuck on certain products?
Trying to use the Config software with the MK3 USB connection. I have downloaded the drivers to my laptop but I don't think they are installed correctly. I can't get past the finding a com port, the software times out and just gives me a help box. I know the MK3 is working as well as the RJ45 cable because if I connect it to my cerbo GX the Multiplus appears on the color control 50 display.
Can I set the charging currents any other way or is this the only way to set the Multiplus up for my new Battle Born batteries ?
