VEConfigure 3

Using VEconfigure and the MK3 attempting to connect to Multiplus 3000 I occasionally see a "Range check error" window appear and the connection attempt fails. What is "Range check error"?

i am trying to connect to a multiplus to use ve config tools using a mac(not windows) i have downloaded wine bottler and have the software installed and it seems to run fine but when i try to connect using auto detect it cannot connect? any help would be greatly appreciated, cheers, stuart

Depth of discharge for a Multiplus ll GX 5kva

We have recently installed a Victron system but we would like the system only to use 40% of the battery capacity and to charge it using the grid, there are 2 X 4.8kwh pylontectech lithium batteries installed with 8 X 540W JA Solar panels with a 150/85 Mppt.2021-07-07 at 15.21.02.jpeg

Hello, As the title says, how do I use VEConfigure 3 to view ripple. Whenever I connect to the Quattro over VEConfigure 3 the load is turned off.

Multiplus C

currently going thru my config of the Multiplus Compact (24/1600).

I already adjusted some settings with help from a distributor, but I'm not happy as there are some unclear values, which I'd be happy to understand.

I plan to charge my LiFePo4 when connected to shore. That can be one day, or 1-2 weeks.

My idea is I don't need to charge to the extreme, as I am on 230V anyway in the charging situation.

Thus, my charging voltage settings are quite low.

LiFePo4 Balancing starts at 27.2 (3.4) end ends at 28.8V (3.6)

My Multiplus Compact float is currently set to 26.4 and absorption to 27.6V.

In The Victron Configure Software, there are some details I don't understand:

https://docs.victronenergy.com/veconfigure.html#charger-settings

Talking about these points:

Charger Settings

4) Lithium.

It seems, when I check this option, I don't have possibilities to adjust the absorption/float voltages, it's greyed out?

I'd like to use Lithium settings, but still adjust voltage values, for me the values are too high, my battery manufacturer suggests to set it lower.

So currently I've unchecked Lithium and adjusted manually.

Not sure if the resulting charge curve is good for LiFEPo4. In my understanding, especially after the absorption is done, it shouldn't hold the voltage any more to protect the LiFePo4 cells from overloading.

So would a "fixed curve" make sense, or what?

5) Storage Mode

How much will the voltage be reduced below float value? I find no values or percentage given in the manual. is there a storage mode for the Multiplus C at all?

11)Battery Type

My battery is a self built 2p8s LiFePo4 220Ah 24V,

So should anything specific be set here at all?

Again: the voltages which are preset for the Lithium mode are too high.

12) Absorption Time

I don t get it. Why will it be limited? Is it the time it stays on full voltage after that voltage has been reached?

Or is it the Time it charges with the Absorption Value, and after this time it goes to Float, even if battery is not full?

If so, where do I set the time it stays on full voltage after it is reached?

Currently set to 1h

13) Repeated absorption interval

I don't get this neither. Why is the loading dependent on an interval, and not on the "Full" status of the LiFePo4 pack?

e.g., the MPPT Smartsolar will load the LifePo4 till it reached the voltage , and eventually swith to float.

So how is this interval setting understood, related to the default loading whenever the battery is not in float or storage mode?

Currently set to 7d

14) Max Absorption Time.

I don't understand. Can u explain?

Currently set to 1h

Explanation to any of these setting values is highly appreciated !

thx

I am using MultiPlus-II controlled by Cerbo GX. I would like to try the "Dynamic current limiter" and "Weak AC" settings as my generator does not produce very stable voltage (it fluctuates sharply in the 220–230V range). These settings do not seem to be available via the GX LAN Remote Console so I would like to leverage VEConfigure on-site (I do not want to use any remote tools).

I have checked the requirements for wired connection: https://www.victronenergy.com/media/pg/VEConfigure_Manual/en/introduction-and-requirements.html

It appears that I need an MK3-USB dongle.

1. Cerbo GX and MultiPlus-II have two VE.Bus sockets each. They are connected together using one, so there is one left on each side. Should I plug the dongle into the GX or into the inverter directly?
   
   
2. Cannot the GX USB ports be used instead, without an MK3-USB dongle? Does not Cerbo GX work as a dongle itself?

Thanks in advance!

It appears that after I connect to a device with Victronconnect, I can no longer reach it using VEConfigure. I just bench tested with a multi and it worked fine with VEConfigure 3, then I connected to it with Victronconnect and now when I tried with VEConfigure or VE.Bus System Configure, I just get the endless dots, then the 'help with connections' message. But I can't reach the multiplus anymore.

Hi there,

Am I right in saying that the settings in this screen will effect how the BMS systems controls the charging of the batteries?

[image]

(NOT MY SYSTEM, ONLY A PICTURE I FOUND ON THE FORM.)

At the moment i have a Fronius 8.2-1 installed with 2 arrays (east and west facing). Each array is 6000w, so it is within the 150% PV over-sizing of the Fronius specifications. The system is setup to do zero feed in to the grid.

The plan is to add a Multiplus ii 48/8000 or 10 000 unit (when they are available in South Africa) to the system with a 16kwh Blue Nova battery. (plus Cerbo GX and what else is needed)

The installed PV inverter power will be 8200w (unit rating)

My question one is this:

What should i make the total installed PV panel power? 6000W or 12 000W

There is no setting or option in these settings that caters for twin array systems (that i could see)

The only time during the year that this system might be able to produce 12kwh is in the middle of Summer at midday, the rest of the time it should be much lower.

Question 2:

Once i do this installation, should (can) I limit the production power of the Fronius to eg. 8200W?

I don't know what will happen if the loads in the house are low and it is a really good production day for the PV. Will all the extra power be pushed into my battery or can you restrict the amount of charge current from the PV to the battery in these conditions. (PV will be connected to the AC-1 output of the Multiplus)

Thank you,

Naude.

I have had an issue with the SOC algorithm and voltage readings. After research on this forum I determined that it was a problem with the voltage measurement difference between the smart solar and multi. I got my SOC back up to 100% by increasing the absorption voltage to 59v from 57.6v. I didn't want to leave it this high so set about reducing the absorption voltage in the multi remotely (I do not have computer access where my solar is). So far, I have reduced the voltage down to 54v and the multi is still not recognising when the smart solar switches from bulk to absorption. I reduced the voltage again and now the multi will not start up, flashing low battery and then overload in quick succession and then switching off. Nothing else has changed in the set up which was working well for a month, SOC aside. I am assuming I have lowered the absorption and float charge voltage too low and it has interfered with another setting. Can I access the multi remotely with veconfigure even when it is off or do I need to buy a Mk3 to configure it directly? I'd prefer to avoid the $100 cost if possible...

Hi,

I have installed a grid-connected PV system (but not feeding back in to the grid), with battery storage and ESS, for a mix of back-up and self-consumption.

I am using multiple instances of the Programmable Relay Assistant to control water heating via the MultiPlus' secondary programmable relay K1, by:

• turning it on when insolation rises to a certain level (measured via a small PV panel's output current feeding a Schmidt trigger, which in turn drives a MultiPlus Aux input) AND AC load below a certain level AND SOC above a certain level, and
• turning it off when any one of the three parameters reverses to a lower / higher value (i.e. with hysteresis).

One particular question is about AND / OR logic - it appears to me that:

1. when more than one condition is set in the one assistant, then it uses AND logic, and
2. to implement OR logic, it is necessary to use multiple instances, each with one condition.

Can anyone confirm from experience or product info', that these are correct?

I understand that the order the Assistants are listed in, in VE Configure, affects how they operate, and that those lower in the list 'override' those higher in the list. I found that my system works approximately as I want when the 'switch on' Assistant is at the top of the list. If I move it to the bottom of the list however, then the K1 relay appears to remain on permanently, irrespective of inputs, and I don't know why that should be.

I'd be grateful for any more specific / exact information about how the ordering of the Assistants functions.

When I tested control using either one of the Aux 1 input or AC load (one at a time only), they behaved perfectly, including with the delay times. However, when I combined the two in one 'turn-on' Assistant, it then appeared to ignore the delay times, and switch on instantly when both conditions were met. Any ideas about what might have caused that?

Finally, with all three inputs combined in one 'turn-on' assistant, with 'AC load lower than 1250W', I had it switching on when AC load was still around 2500W, so either it is not actually AND-ing the inputs, or the parameter is not working correctly.

Does anyone have information about exactly what the 'AC load' parameter reads?

Thanks in advance!

I've got a cerboGX, Multiplus 48/5000/70, and SmartSolar 250/100

Can I configure my system via the software, VE Configure? (The first page of the manual makes it sound like the program is only compatible with certain Phoenix inverters and nothing else). If so, what accessory cable do I need to connect to my laptop if I want to do everything without internet access or bluetooth?

Hi Newbie to this and forums in general.

I have an old generation Phoenix Multiplus 24/3000/70 dual or daisy chained charger inverter system on our boat. We have used it with 10x250AH lead acid batteries configured for 24VDC. I want to change these for lithium and want to know if i can get the inverter charger programmed to charge the lithium batteries. I am also looking at purchasing an electrodacus SMS0 in support of it if that helps in answering the question?

Is this a reasonable graphic showing how to configure, control, and monitor Victron equipment?

Victron Configuration, Control, Monitoring Logic.pdf

I've got a 24V set of Fusion Traction for a my offgrid house in WA

7PzB525H Lead Acid 2v

I understand its a 27V float

What about Absorption, max Time, Equalization

My understanding is these batteries require no top up even though the cap comes off??

Am trying to get a hold of Fusion directly, but there is no answer and the email doesn't work

Are they still operating

Many thanks

Hi there,

One of my systems is not displaying the VEConfigure & Firmware Update buttons as well as reporting limited information of the Venus GX as shown below. Do you know the reason?

[image]

What is the minimum input current limit for Quattro?

Setting it on VEconfigure allows me to set it as low as I want. However, the input current limit won't go below 10.5 on the Colour Control.

It needs to be set lower as the customer only has a small generator. How do I do this?

I am installing VE Config for the first time on a an older windows Toughbook with windows 7 operating system which I run as it is compatible with some older Navigation software I have on the machine.

The error I am getting with installing VE confi is:

Fatal error:
Cannot find VERSION.DATfile!

I am a mac user so not sure if its a windows thing or and issue with VE Config

Thoughts on this appreciated. thanks in advance.

Thx

Hi everyone,

Does anyone know if the MultiPlus 3000 can be configured to allow the ac load only when plugged to shoreline? I want to make sure that my ac load is only working when I am on shoreline, and save the lithium house batteries for the dc load.

Thanks

I can download my Multiplus config through VRM and edit it in VEConfigure. But when I try to close VEC to upload the new settings it insists that a Grid Code is needed, although the Grid setting is 'No...'. So I can't alter the Multi. Any suggestions?

This only started recently and the only change might be a firmware upgrade.

MultiPlus 24/3000/70-16, firmware 401
VEConfigure 90.04.223

I recently bought a Multiplus control print of a Victron Multiplus 12/2000/80 and want to use it in the same Multiplus of which the control print is broken.

But when I connect it and want to set it with an MK3 with the VE config software, it shows that it is an inverter 'Phoenix Inverter 12/2000' while the firmware in the chip is version 1908159, see screenshot;

[image]

From the document 'VEBus firmware numbers' I read that firmware starting with 1908 is a 'MultiPlus Compact 12/2000 / 80-30' version. What do I have to set / configure to make the control board function as a Multiplus again?

Thank you

Hi,

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.

Is it possible to change the delay which it takes for AC out 2 to go live?

I have contactors which are being driven by AC OUT 2, but when the grid or generator input is live (after a mains failure or return) it takes around 2 and a half minutes for AC2 to go live, and hence close the contactors... Is there any way to change this to 30 seconds for instance?

Hi all,

Can someone point me in the right direction on how to connect to the above inverter/charger as it‘s an older model it seems I may need a different interface. I currently have the MK3 USB one which doesn’t want to work with this unit. I’m using VE Configure 3 and can connect to the newer multi plus’ no problem. It doesn‘t matter which one of the ethernet ports I plug into, it just wont connect.

I need to modify the charge and float voltages and using those buttons really isn’t straight forward when you‘re not used to doing it, hence laptop and being able to see the actual values is best here.

Client doesn’t have the manual and I’ve tried downloading it from this site but I can’t seem to find the right one.
It has another two sockets which could be VE. Direct but they are black and VE. Direct are usually white.

It also has a remote panel which I unplugged incase this was causing any issues...hence that unplugged RJ45 blue cable.

I’ll attach a couple of photos as it‘s better for you guys and girls to see the PCB.

Huge thanks.

Hi,

I have an old Phoenix Multiplus 24/3000/70 with family group 18 according to the documentation. Microcontroller sticker says "1812144.HEX". Is there a way to upgrade the firmware to a newer version that supports VE.Bus? I know the microcontroller is not compatible with firmware version 4xxx and newer.

I have a MK3-USB.

Good day to all. I am fighting since 3 days and do not understand what the problem i have can be .I use a new (but old !) laptop PC to make changes on VE Config to our system. I have downloaded all the VE config data from Victron website . I cannot change my configurations ; neither via VRM, nor with MK3 adaptor .

- When via VRM, I can access the installation, change all settings . I can download the existing settings, save them . When I want to upload the new settings , I get the error message saying : "YOU CAN UPLOAD ONLY A SINGLE .rvsc or .rvms FILE " ??

- When via hardware (MK3 ) , it never finds the port . I have the proper cables from Victron and had done it many times in the past, so quite familiar with how it should go ?

There is probably something wrong, but I can't find what .

Anybody having the great idea to help me solve this problem ?

Thanks and regards

Why can't I find veconfigure2.exe on the internet? My old Multiplus and my MK 2b interface only works with that software version - despite Victron telling me veconfigure 3 will work!!!!! I need to renew the old software which has worked for the last 15 years after my computer crashed.

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 ?

I would appreciate some assistance or feed back on VeConfigure . I don't know if I am the only one but I am experiencing difficulties to configure each time I try to. This week only , 3 times on 3 different installations with 2 different laptop PC and trying with 2 different MK3/USB adaptors and 3 different Victron RJ45 cables. I may be doing something wrong ?

This is what I do.

- disconnect CCGX or Cerbo

- Insert RJ45 on Vebus port of multi or quattro

- Open Veconfigure on laptop

- connect rj45 end to MK3/USB adaptor

- connect USB end to laptop

- in Ve configure, go to PORT/SELECT PORT/AUTO SELECT.

- system look for ports. Dots appear one after the other while searching .

From there , 2 different scenarios :

A/ no port is found. Get a popup. Help on communication. That's it

B/ Get a popup. MK3 detected. But the usual VEConfigure tabs do not appear. Nothing happens from there !

So I experienced these 2 issues this week.it's not the first time. These 2 installations are NOT connected to the internet so I cannot change settings via vrm. I need to change VS settings.

Grateful for some assistance or feed back. Hate thus situation in front of a customer !

Thanks and best regards.

Merry Christmas!

Is Victron planning to recompile the Victron Connect App to target the new Apple M1 MacBook Air and MacBook Pro?

I know you can run it in compatibility mode but this isn't optimal. It would be really nice for Victron to specifically target the new M1 Silicon!
