VRM

The application is http://www.wilhelmsk.com

It has been around for a while but has always required extra hardware and software to get data from Victron systems (a SignalK Server).

It now has the ability to display data directly from a Venus device or from VRM.

I'd like get about 5 testers to try it out before I release to the general public.

Requirements:

• Have a Venus GX or CCGX
• Be running the latest release candidate software
• Or your data is available on VRM
• Have an iOS device running iOS version 10.0 or later

If you'd like to help out, please send an email to support@wilhelmsk.com and include your Apple ID email address.

Thanks!

My installation is on a boat:

2x 110AMP batteries as "house bank" (bank 1)
2x 110AMP batteries as "Starter battery and bow thruster" (bank 2)
The batteries are: Lucas LX31 110ah Leisure Battery
The two banks are connected via a Cyrix-ct 12/24V-120A (CYR010120011).

Connected to bank 1 are the following:
One BMV-702 (BAM010702000R) with 3x 160Watt solar panels
One SmartSolar MPPT 100/50 (SCC110050210)
One MultiPlus 12/3000/120-16 (PMP123020001)
One Venus GX (BPP900400100) (https://vrm.victronenergy.com/installation/36369/share/820f64ab)

Connected to the Venus GX are the following:
BMV-702 (BAM010702000R)
SmartSolar MPPT 100/50 (SCC110050210)
MultiPlus 12/3000/120-16 (PMP123020001)

My question:
On the VRM portal and Venux GX I only can see the "AC Loads".
But the MulitiPlus has two AC OUT. And I have both AC OUT in use.
Is it somehow possible to see the use on AC OUT 1 and AC OUT 2 instead of only "AC Loads"?

Hi

Our system was working so far fine however since yesterday 2am we cannot see data on the vrm.

There is internet on the site. The system is up and running fine.

Could you please check if you receive any data :

System name is : Ezine Off-Grid System

Portal id : 9884e38d3c27

I’ve taken the following totals (kWh), from VRM from my last 290 days of operation:

[image]

(Rig: PV + Smartsolar 250/60 + Multiplus II 3000 + Venus GX + BYD 5,0kWh)

Total From = Total To = 12 130 kWh, so the losses must be "hidden" somewhere in here.

VRM reports 2016kWh charged to the Battery, but only 1325kWh discharged from the Battery. So, a 691 kWh loss.

Considering that the “From Grid” and “From PV” measurements are most certainly made before conversion losses [made, respectively, by the Carlo Gavazzi ET110 (in green) and SmartSolar MPPT (in blue)], am I correct to assume that this 691 kWh loss includes ALL inverter/charger losses, specifically:

• Grid AC -> Battery [charger] <- implied in the VRM data
• Battery -> AC Consumption [inverter] <- implied in the VRM data
• PV -> AC Consumption [inverter] <- this one is not implied.

Can anyone confirm this?

Sanity checks:

• The 1 325 kWh discharged from the battery are in line with the number of cycles I believe my battery has made (~1 cycle/day).
• 691 kWh losses / [2 519 kWh PV Production + 939 kWh Grid to Battery] = 80% total efficiency, which seems in line with the literature.

I've connected my SmartSolar MPPT with VE.Direct to a Venus GX and VRM. I have a DC load connected to the "Load" site of the MPPT and the Venus sees the load current in the Remote Console, but this is not logged in the VRM.

Is there a way to get the DC load readings in the VRM? Right now the solar yield in the VRM is net of the DC load on the MPPT. I tried enabling the "DC Load" in the settings, but this must be for another configuration.

As a general product suggestion, the Venus sees a lot of real time data that is not logged to the VRM. I hope this is on the VRM roadmap.

I have set up scheduled equalization for my Bluesolar 100/30 and 150/70 (EasySolar) MPPTs that are both connected to CCGX. The problem is that VRM graph does not show equalization even thought it happens - battery voltage is increased and VictronConnect shows it (if connected to MPPT). However, if I start manual equalization, that is properly indicated in VRM.

Somehow, remember that last year such scheduled equalizations were visible in VRM. Is there a reason why this has changed?

Probably not a huge priority for you guys, but could you please make an apple watch app for the VRM app?

I also remember reading about a new vrm app, is this still in the works?

Hi,

The internet at the customer site went down as did the mains power., The system was functional during the whole time as there are 10kwh LiP04 batteries and virtually no load to speak of. The internet connection is back up yet I have missing data for about 15 days.

Set up is 36 x 320W PV Panels 5kva Multiplus, 3 x 150 MPPT, GX Colour Control, 10kwh LiP04 battery. What could the reason be for the missing data. We log every 15 min and do not have a micro SD card installed yet have 26.43M bytes of free disk space. Will adding a SD card help and if so what is the recommeded size?

The graph selector on the dashboard disappears after the page has loaded and is not visible, and I can only see the system overview. What determines when this selector shows?

Thanks

On the map above "My installations" on the VRM portal the status of my installations are shown as "Alarm" even if the last alarm was cleared many days ago.

Also "Last update" is shown as Realtime on one of them even if the logging interval is set to 5 mins.

Hello. My installation: 3xVictron Multiplus II, 1x MPPT, 1xColor Control GX, PV installation 4kWp and 2 batteries lithium-ion BMZ 13kWh. Where i can find information about data meaning from VRM report? For example what the difference between "VE.Bus System [0] Battery current" and "Solar Charger [258] Battery current"? Or what does mean "System overview" position?

I have an older multiplus with a legacy CPU and control board that cannot report cumulated energy from its AC inputs/outputs. Because of that, I cannot see nice graphs in VRM about the energy used from the grid and thd energy obtained from the PV.

I would like to keep my Multiplus because it works well otherwise. I was wondering if I could install an ET112 energy meter at the AC input of the multiplus to get the same functionnality.

I'm not adverse at writing a service to generate proper data stream in Venus OS. My questions are:

- Theorically, if I mkdify VenusOS, can the ET112 provide simikar functionnality?

- Does it work out of the box ?

Thanks

Hello,

According to the „Last 24h/7d/30d“ diagrams in the VRM portal, someone could assume, that I use a lot of grid power. In fact, the meter of my grid company shows me a total consumption of only 4kWh(!) for the last full month (last 30 days).

[image]

Ok, it is true that a lot of power comes from one grid phase but that is nearly 100% compensated by the battery power on the other phase. I’m running a 1-phase ESS system with activated phase compensation. And exactly that is unfortunately not considered when calculating the above VRM diagrams and charts.

A test with my dishwasher (17:30 to 18:30) on phase L2 shows that nearly everything is compensated by the Multiplus 24/3000 on L1 (from battery).

[image]

Battery power (discharge) at the same time period

[image]

Consumption tab at the same time period

Here comes my issue - you can now see a lot of grid power usage, but in my opinion there should be nearly everything blue (battery usage).

[image]

For me, the above diagrams are quite worthless and it would be fine to have some VRM settings to change the behavior of the consumption calculations with activated phase compensation.

Any ideas how to improve this?

Best regards

Rainer

Hi Support my VRM Dashboard has stopped displaying data during the last week or so, some time during the last week in April 2019.

I've made no changes to my system and have all the latest updates on my equipment, nor have made any changes to my configuration.

This has happened before last year and when I reported the problem to Victron it was fixed. I think it is something to do with VRM cloud system.

Thanks in advance for fixing.

I am looking at the log data available from VRM and am trying to distinguish between the normal DC load and the dc load due to the inverter. It seems the current and voltage are in the logs but i am unable to find a log of the input KWhs. Is this available anywhere?

I would like to see my power usage on AC vs DC systems.

Thanks,

Dalon

Hi just some info for everyone incase you did not know about it, as I myself found this mentioned on a post and I was not aware of the feature.

If you enable two way comms on the Venus or the CCGX,

then you can remotly configure the units via the VRM

Nice Feature

Something's not right!

Just for one hour, seems the decimal place was moved!

[image]

I have a client who has a 3 phase 3x 10Kva quattros , 1 was giving problems I am yet to get to site its very far away. I sent a replacement unit and always was able with ve power setup to reconfigure an entire 3 phase system and re setup to work as a 3 phase system. It wont let me use ve power setup and when I download the file from VRM it only gives me the new master unit and cant get the system configured to 3 phase remotely? or I am I missing something ? Any help appreciated

Hi,

I have a system installed with:

- One grid inverter [SMA Tripower (STP) 20kW + SMA Home manager 2.0];

- Three multiplus II (3kW, each);

- And a 3.7 kWh battery made of eletric vehicle modules with a BMS with two signal;

- One carlo gavazzi meter ( EM24DINAV53DISX );

- I'm using ESS with two signal BMS control;

[image]

The 20kW SMA is setup for zero injection on the grid (self-consumption), but sometimes it does feed power back to the grid since the three fase loads vary in time.

I have 4 questions:

(1) - The multiplus II is not delivering power back to the loads when they need that power (i.e. when there is not enough sun and the battery has 100% SOC), how can I comand the inverters to pull the energy from the batteries and delivered back to the loads? I'm trying to avoid at all costs to inject power back to the grid.

(2) - I have a Venus GX + warning LEDs installed in the DC bus bar of the battery, this loads are pulling energy from the battery and voltage keeps following. The Remote console and the other graphs shows the SOC at 100%, but I know that it's not real, since for my battery 64V is 100% SOC and 52V is 0%, how can I control the SOC and display the correct SOC values?

(3) - I want to charge the battery with all the inverters installed in all three phases, but when I was configuring the assistant, he only offered me the possibility to have one comand to the battery BMS, how can I do this? I have already three relays for each inverter, but right now I'm using only one input.

(4) - I want to store the excess of eletricity in the phases that are unballanced, how can I do this? I can see in the tab (advanced) at VRM what are the phases, that are unballanced but I'm not able to pull that energy into the DC bus bar back to the battery or back into one of the other phases. I know that this is not the most efficient system, and that, I'll lose energy in this process, but I need that configuration.

I've already read many articles in the Victron Live web page, but didn't found the things that I was looking for, here are some examples:

https://www.victronenergy.com/live/ess:design-installation-manual

https://www.victronenergy.com/live/ess:quick-installation-guide

Etc;

Thanks for your attention and feel free to ask me another questions.

Have a nice week,

José.

I'm finalizing the design for a 2019 project. Clients prefer if VRM can display the wattage of their first Fronius Symo inverter separately from the wattage of their second Fronius Symo. I had planned for the two Symo's to share one Data Manager 2.0 card, hence only one connection to the LAN.

Does VRM always combine the Symo wattages into only one number? What if I used a second Data Manager card so each Symo has a separate connection to the LAN?

OR: is Fronius Solar.web our best bet for seeing the solar data in more granular form?

OR: your other suggestions would be welcomed. Thanks in advance~
