config

Hi.

I've a Multiplus 48/5000/70 with firmware 400. When I connect it with a MK2-USB and the latest version of VEConfigure 3, they retrieve all parameters but if I white new parameters to the inverter, the program stops at init of writing and show me an white error.

If I use an old version of VEConfigure (the version that need the password), is no problem to read/write parameters to the inverter.

The problem is the old version of the firmware?

And, other question: for change the Grid country, i will need a password? What is?

Thanks!

I’ve used a pc to update the firmware on the multiples compact 12/2000 to v209. (I could not update it from my Mac because the firmware was so old. So I had to borrow someones PC). Now I can see it with my ViltronConnect on my app on my Mac. When I start it, however, I get a message that states that my firmware needs to be updated from v209 to v4+. It does not update it automatically.

When I go to settings to update the firmware, I need a dealer passcode to do anything.

I’d like to update my firmware and settings - how do i get a passcode to do so?

Next, I have (3) Relion 300ah batteries. I don’t know the settings for the multiplus for these batteries. Do I need an assistant loaded? I am in desperate need of configuration help. I’ve looked at all the manuals and, frankly, they contradict each other or they don't outline the lithium settings by each tab. So I’m stumped.

When I use my toaster oven with the inverter, the “overload’ light comes on. The specs are 1800W max power consumption, and pulls 15amps when at full power. Is that a setting that I need to change on my inverter to allow it to work?

How do i configure the multiplus to use our Honda 2000i generator? Do I need any assistants?

Our boat is on the hard for 4 months this winter. Do I need to change the inverter settings for possible cold weather?

Help!

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

Is there any way to configure my easysolar 48/5000 without VE.direct to USB?

How can I set a static IP address for the Venus GX Ethernet Port using the VRM portal or the local WLAN access (Remote Console)? Whenever I set the IP modus to manual in the Remote Console there is no possibility to input the IP, network mask or gateway.

Thanks in advance,

Hi All,

I seem to be unable to configure what I was told the EasySolar could do. It’s possibly my fault, but if not it’ll be a feature request that I think would potentially sell a lot more victron units in Australia.

If one selects “grid code” of “none” it seems I cannot use PV power unless in powerassist mode, UPS (in Ac-in fail) or batteries need charging mode. Ie under normal operation (grid/generator present) PV power will reduce as the batteries charge, and even though I have 1.6kw of panels I’ll see charging of just 20w etc.

ESS cannot be started with a grid code of “none”

ESS cannot be started using the Australian grid code (it warns that a secondary relay is not present in the product)

Selecting UK (and others) will allow the ESS to start and one can then select “use excess PV power to feed into the grid” which then will use all PV power available (Which majority of the time is lower than the load).. but obviously this would be non compliant (and therefore illegal) if running without an anti-islanding relay.

I have also noticed I have to set “keep batteries 100% charged” for it to work, using “optimized” will cycle the batteries.

Setting “power assist” will work sort of... if I set the limit input to 4.5A it will use a couple of hundred watts to power the load, however it will never use less than 700w no matter if I set the input limit to 0.5A... (it just sets itself back to 4.5 in the GX) ... and worse (for my situation) should the load go over the available PV power it’ll discharge the batteries.

So nothing does what I want to do.

I want to use the easy solar as a UPS and have the PV power reduce grid power. Ie:

I have “cranker batteries” (24v 200Ah flooded flat lead plate) so they should be just used when there is a grid failure. Grid is stable for most of the year but I have a lot of computers hence needing/wanting to use “UPS” mode. I do not want to feed any power into the grid,.. just downstream to the loads. If there is excess PV power after the batteries are charge and the grid consumption hits zero just reduce the output of the MTTP charger. (This is got local regulations compliance... domestic premesies are not allowed to feed in more than 6kw of power.. which I wouldn’t anyhow, but as a consequence no installer will install greater than 6kw without an upstream limiter and non seem to want to do Victron stuff.. so I’m installing them (EasySolars) as UPSs for each power rail in my mini DC.. i’ll End up with >6 of them and 18kw of panels if they can actually do the job I need.)

Thoughts/direction welcome.

Je ne comprend pas les paramétrages à effectuer pour faire travailler un module MyPv Ac-Thor sur un système off-grid DC.

L'article (https://www.victronenergy.com/live/actor_offgrid ) parle de passer en mode “Frequency-Mode” et d'installer le "PV Inverter support Assistant". Je ne comprend pas la logique de cette démarche dans un système DC. L'information doit venir du BMV via le VenusGX, pas du multiplus.

Serait-il possible d'avoir plus d'informations sur ce couplage ?

Cordialement

Hello,

I do not understand the settings to make to work a MyPv Ac-Thor module on a off-grid DC system.

The article (https://www.victronenergy.com/live/actor_offgrid) talks about switching to "Frequency-Mode" mode and installing the "PV Inverter Support Assistant". I do not understand the logic of this approach in a DC system. The information must come from the BMV via the VenusGX, not the multiplus.

Would it be possible to have more information on this coupling?

Cordially

Hi, I'm trying to connect and "old" Multiplus with my computer to update some settings.
I'm trying with the latest VeConfigure 3 version with an updated MK2 dongle but I only get errors. (After "Retrieving supported functions" and the progress bar, appear another message "reading Block 1" and then "Error during communication, YES/NO/HELP").

Also tried with a new MK3 updated but I can't stablished connection to the unit.

Also tryed with the VeConfigure version 90.03.120 and the MK2 but the software says its not compatible with the Multiplus version 1812144.

Also I have updated the USB Serial drivers that I got from the VeConfigure in the "Special" tab in the main menu, but nothing change.

In every step I had restarted my PC and the Multiplus.

If somebody can send me a tip I will be very grateful.

Thank you in advence!

Dear All,

We are installer company and purchased a 30pcs quattro 48/10000, 60pcs MPPT smartsolar 250/100 and 30pcs CCGX display in last 2 years. now, i have problem on one inverter completely dead.

I can't find a picture, wiring diagram, or list of relay physical connections to the BMV-712 Smart in any of the posted Victron documentation.

But the manual defines all of these relay functions: "alarm relay", "low voltage relay", "SOC relay", "high voltage relay", "low starter voltage relay", "high starter voltage relay", "high temperature relay", "mid voltage relay".

In googling around, I found what claims to be a picture of the back of the BMV-712 with only two wire connection that might be a single relay interface. I don't know if that picture is accurate.

Are there multiple relays for user external connection or one? If one, are all those functions mentioned for setup using the same relay, implying I need to use the USB data connection to determine which function toggled the (single relay)?

I need this information to design my system.

Can it be done, how and where to install it?

Hi from a longtime Victron reseller in Colorado. I have a solar home sales opportunity where there are no code inspections--hence little worry that Quattro has no American style UL1741 label.

AC coupling or DC coupling is still undecided but either way I need approval to "sell" excess energy into the "mains". Lawfully grid-tied Victron may be a first for this side of the pond.

The public power company wants compliance with "IEEE Standard 1547 Guide for Distributed Generation Interconnection". Here's a link:

https://standards.ieee.org/standard/1547-2018.html

but is that equivalent to any of these grid code standards in VEConfig3?

The mains engineers are more likely to approve the intertie if I can document Victron compliance with IEEE1547.

How about that Victron Energy Staff? Any thoughts or help? Thanks in advance~

i have a BMV 712 that has been monitoring a 12v 200amp hour battery for the last year - working great. Yesterday i installed a 2nd battery to the system (2 12v in parallel for 400ah). I noticed after firing up the system that over night, the state of charge said 100%. I changed the number of amp hours in the setup for the BMV. Do i have to do anything else?

Hello Victron community,

I'm about to end my camper van conversion, and it's time to set up my electrical devices !

My system is the following : a multiplus 12/800 inverter/charger + a li-ion 160Ah battery + SmartSolar 100/30 + BMV 700 + VE.BUS BMS + DigitalMulti Control.

I read in the VE.BUS BMS manual that I needed to install the AC detector in order to restart the Multiplus. So I did, but it seems that I have now to set up correctly the multiplus with the "VE.Bus BMS assistant or the Self-consumption Hub-2 v2 assistant".

My question is : What is this assistant, and how to load into my multiplus ? Do I need the MK3-USB interface ? It's not so clear in the manual... I currently set up the Multiplus with the DIP switch only.

Thanks for helping

I was reading paper version manual for my BMV today, just to review my setting and try to learn more about it. But I got confuse cause I think there is contradicting information within. I had to go check the online version, to check if it was a typo that was maybe corrected. But I find the same error (!?) in the online version of the manual.

I'm saying this, but I might be wrong and confuse, please correct me if I'm wrong. I would really like to know which info is right or if the 2 info I think are contradicting are just 2 different info that I think should be the same..

so at 2.3 commons problems it is mentioned:

[image]

and when reading further, at 4.2.1 Battery settings under 02. Charged Voltage we found that:

[image]

and then if you just the mentioned section 3.7 (in blue ^) the mentioned voltage (13.2v) is proper for float and not for absorb, so think section 2.3 is wrong, unless I am just really confused and those 2 pieces of information are not related to each other...

so to add to my confusion, when I look at my own setup in the BMV, charged voltage is set to 14,8V, which I don't remember having set that, but I would really like to know if this is right or not

If ever i am proven to be wrong, i would like excuse myself in advance since english is not my first language

The Victron Connect App is reporting the voltage on my battery as approximately 1 (one) volt higher than it really is. By "really is", I mean that I am witnessing the battery voltage, firstly on the in-built voltmeter on the Motor Home control unit and again (using a good quality) voltmeter at the "BAT+ & BAT-" terminal of the 75/10.

The image below, hopefully shows my test layout. There is also a video.

My assumption is, that if the 75/10 is "miss-informed" on the actual battery voltage, all management functions are probably in error too? For example, when the 75/10 thinks that my battery is at 14.2v - it is not! It is only at 13.2v etc.

How can this be corrected?

Best regards, Martin

Is it possible to connect the MultiPlus directly to my laptop using only a RJ45 cable? Or is it absolutely necessary to use the MK2-USB or MK3-USB adapter? My laptop has a RJ45 port, but the Victron videos ONLY mention using the USB adapters.

red light low battery always on.

battery pack 13s3p of yuasa lev50n (max volt 4.1 and min volt 2,75 - 50 A)

REC Q BMS

min volt pack 2.75x13 =35,75 V

max volt pack 4.1x13=53.3 V

when not enough photovoltaic never works battery only the external grid as backup

ESS installed and all firmware ok

some help in ESS configuration

I have a MultiPlus 12/3000/120/16 connected to my batteries and also a BlueSolar MPPT 100/50.

Is it possible to configure the MultiPlus so that it will prefer the sun to charge the batteries, and if the sun isn't strong enough, it will be supplemented with shore power?

Good day. I am a bit confused with "how to" set / Program the easysolar 1600/24.

I have installed:

- Easysolar 24/1600

- BMV700

- Color control

i have purchased VE Direct to USB interface cable , Interface MK3 - USB (VEBus to USB) ,VE Direct cable.bluetooth dongle...

Where I need help :

1- I have connected the BMV 700 to the shunt and have all readings on the BMV 700.

2- I am having difficulties connecting the color control. I am a bit confused as to which ports must be connected.

- On the EasySolar, I clearly see the VE Direct port of the charge controler, but I do not see any port on the inverter part ; So I wonder how to connect ( to program) the inverter part of the easysolar to the color control.

Could someone help me by telling me which cables do I need to do this configuration, and where to connect them ? i have been looking for videos and tutos but can't find any .

Greatly appreciate your help.

Thanks

According to this video from Victron is should be possible to see Venus GX in the VictronConnect App.

Sad enough I can't seem to find my Venus GX.

It's online and working... WiFi is active...

Is there something in the Venus OS I need to enable?

Bonjour,

J'ai un régulateur victron mppt 100/20, un convertisseur victron 12/375va. Je souhaiterais utiliser la sortie de charge de mon régulateur en tant que sécurité basse tension pour mon convertisseur.

De ce que je me suis renseigné, je retiens que je dois laisser le shunt sur la prise "remote" de mon convertisseur et rajouter un fil qui part de la borne de gauche de ce shunt et le raccorder à la borne + de la sortie load de mon régulateur. Vrai ?

Merci par avance.

Is the consumption shown on the dashboard the total consumption or does it exclude those circuit breakers not backed-up?

I can't get CCGX to turn on. Help!

Situation

1: CCGX is powered from the positive and negative bus bars (confirmed power to end of cable). Red on top and black on bottom.

2: CCGX connected to Multiplus via UTP cable.

3: No power (i.e. CCGX screen is blank).

Remedy steps tried:

1. Unplugged power from CCGX and verified with multimeter.

2. Unplugged UTP cable from both CCGX and Multiplus, then plugged back into both.

3. Reset CCGX (Buttons E + A + B)

Note: CCGX has firmware version 2.04 out of the box. I have not updated.

Will Load output on SmartSolar MPPT 100/20 cut of on the positive (plus) side and the negative (minus) is unaffected or how is it works?

Can I ask if mixing different components from differing manufacturers is ok? For example I have a Stirling B2B charger, a victron inverter/charger, an Epever MPPT and a couple of Valence lithium batteries. Sorry if I sound a bit naive- I'm new on configuring things out!

Cheers

Hi all,

I understand you can build a multiphase system by using multiple devices, and also you can increase available power by parallelling multiple devices. I also understand the models and firmware used need to be the same.

Is it a requirement that all phases in a multiphase system have the same amount of devices in parallel?

Just clarify the question: Is it possible/desirable/supported to build a multiphase system where power for L2 and L3 are provided by a single device, and L1 has 2 devices parallelled because this phase has a higher power requirement?

Thanks in advance!

Best regards,

Johan.
