This is more or less continuation of my previous case:
I still don't understand the Quattro's algorithm when switching inputs:
- AC2 (lower priority) input is active from grid
- Generator starts in AC1 (higher priority), voltage is detected in AC1
- AC2 is instantly dropped + inverter activated
- AC1 remains inactive, AC2 remains inactive
Why drop the working grid (AC2) if the generator (AC1) is not accepted? What is the point in that? I've crashed my servers behind Victron many times because of that, when the batteries run dry. And yes, It's good reason to start generator when batteries are dry.
Inverter SHOULD NEVER DROP OUTPUT IF THERE IS POWER AVAILABLE.
I thought that would have been kind of obvious, but it's not. Could it be fixed?
Could GX provide clear information why Quattro doesn't accept generator power?
I'm trying to find led codes for Multiplus Compact.
The manaul shows only basic ones, the Victron Tool app doesn't cover Multplus Compact at all.
One of my two Multi Compacts working in parallel shows blinking both red and green led, what does it mean ?
The current setup is 3x5kw quattro to supply an AC bus and a 3phase AC bus ... this is used for many loads (like washer/dryer/fridge/etc AND steering pumps) ... lets call this the MAIN-INVERTER-GROUP.
I would like the steering pumps (which are 3phase AC) to be setup their own inverter group ... lets call this the STEERING-INVERTER-GROUP, this way the critical steering system is isolated from non critical things. I would also like the the option to flip the power source to the MAIN-INVERTER-GROUP in case one of the inverters in this STEERING-GROUP dies.
Basically some isolation and backup for steering.
Is there any issue/advice on setting up a system like this?
I have a few hand sketches which are not very good, but could add if that would help.
-- Thanks !
I have the following problem when setting up the Victron EV Charging Station:
When scanning for Wif-Fi networks, the EV Charger sees the Cerbo. When I want to connect to it, the message "An error occured during applying of new settings!" appears.
I think the problem is that the EV charger has a very weak wifi signal. At more than a meter away there is already almost no signal. If I stand behind the wall where the charger is hanging, there is already no signal at all.
It seems to me that the charger's wifi signal cannot possibly reach the Cerbo (about 4 meters away).
Is there a solution?
Hello Victron Community,
There is a new feature to make it easier to keep an eye on your Victron system,
These allow you to show the vital power system information right on your phone Home Screen without even needing to open the VRM app.
How to get started;
Step 1: goto your app store, and update the VRM app if it hasn't already
Step 2: open the VRM app, make sure you're logged in.
Step 3: go to the phones widgets screen, in iOS this is by swiping to the left-most screen.
Step 4: scroll to the bottom and press the edit button you see there
Step 5: click the plus button on top left
Step 6: select the VRM widget
Step 7: select one of the many types of different size and layout (try them all)
Step 8: press the + Add widget button on the bottom
Step 9: press done; (even though the widget says to select an installation wait till the next step)
Step 10: tap and hold the widget until the "edit widget" option becomes available
Step 11: choose an installation by tapping only once on the installation selection, and then choose your installation from the list that appears
Step by Step Video;
Further documentation is being prepared, so please feel free to ask any questions here.
We'd also love to hear any feedback, be it positive, problems and suggestions for improvements.
As an idea - a possible next step is that we are looking to also add widgets to VictronConnect, which work via Bluetooth.
It seems very likely, from the email below (names and some details omitted) that the docs you submitted to ENA in early October will not be sufficient to gain compliance "due to important information being either incorrect or missing altogether".
Please could you provide some kind of timescale for when you will be able to provide updated documents? I note that NGED are, helpfully, willing to liaise with you in order to speed up the process.
Providing a response on this forum would, I'm sure, be very welcome by customers like myself.
I have been asked to contact you, to explain the current compliance status, with regard to ENA EREC G99/1-9, for the Victron Multiplus II 48/5000/70-50 and Victron Multiplus II 48/5000/70-50 GX (which share a common compliance report).
As you may already be aware, as of 1st September 2022, any device that is recognised as an Energy Storage System (ESS) had to meet the full technical requirements of ENA EREC G99/1-8 (and subsequent revisions), where they were previously exempt from some of the newer requirements, that were introduced by the European Network Code: Requirements for Generators (RfG). This requirement was communicated well prior to September 2022, and was published in EREC G98/1-5 and EREC G99/1-7 in August 2021.
Many manufacturers pre-empted this change, and made their ESS compliant before need. Others waited until the deadline to submit renewed compliance documentation.
Where an ESS device had not met the requirements on 1st September 2022, it was marked as ‘non-compliant for new installations’, by WSP, in the ENA’s Type Test Register, and manufacturers were pushed to renew their compliance documentation.
The ENA, WSP and DNOs have the authority to determine Generating Unit compliance under (to name just one document, to avoid confusion) ENA EREC G99, which is an Annex 1 document of The Distribution Code of Great Britain (DCode).
DNOs have a statutory obligation (and licence condition) to abide by the DCode and (in particular) its Annex 1 documents.
As the Victron Multiplus II 48/5000/70-50 (ENA Type Test Register reference: VICEN/02689/V2) Energy Storage Device’s current status is ‘awaiting assessment’, in the ENA’s Type Test Register, I have conducted an in-house assessment, in order to provide our customers with a response sooner than we would be able to if we were to wait for WSP’s assessment. My assessment is based directly upon the requirements within EREC G99/1-9 alongside prior assessments by WSP (what they will be looking for), and my own experience.
I have assessed the Victron Multiplus II 48/5000/70-50 and Victron Multiplus II 48/5000/70-50 GX as being ‘non-compliant’ with ENA EREC G99/1-9, as things currently stand, due to a number of shortfalls in the compliance form. As Victron have made their form publicly accessible, via the ENA’s Type Test Register (i.e. it’s not a restricted document), I believe that I can elaborate upon this:
Advisory and failure points:
[information which could be considered commercially sensitive omitted]
Hopefully, you will be able to see that this compliance status has not come about due to minor inaccuracies, which could be forgiven, but due to important information being either incorrect or missing altogether.
As a consequence of these findings, National Grid cannot accept the connection of the Victron Multiplus II 48/5000/70-50 or Multiplus II 48/5000/70-50 GX, in parallel with our Distribution Networks, until such a time that Victron have provided alternative or additional information that demonstrates compliance with the latest version of ENA EREC G99.
I am comfortable with you informing Victron of the above, either directly or indirectly (through your equipment supplier), so that they may complete and provide alternative or additional evidence of compliance. They should do so primarily to the ENA, but National Grid Electricity Distribution would also be willing to take an early look at any documentation, should Victron see this as desirable.
I am confident that, given time to complete the documents accurately, Victron will be able to make these devices compliant (perhaps with another firmware update) but, unfortunately, we will have to wait until they have demonstrated this before we may accept these on our networks.
Bonjour à tous
Je possede actuellement un systeme pour site isolé comprenant 4 PV de 400 w ( connectés 2X2 orientés sud) connecté à un regulateur smartsolar 150/35 lui meme relié à un MultiPlus 48/3000/35-16 raccordé à un parc de batteries pylontech ( 3 modules US2000 , 48 v ) le tout géré par un Color control GX ( smartsolar en ve direct , batteries et multiplus en rj45 )
Je souhaite rajouter 3 PV supplementaires via un 2 eme smartsolar 150/35 qui eux seront orientés sud ouest afin de "soulager" mon parc de batterie en fin de journée et augmenter ma capacité de production par temps gris
Je précise que le parc de batterie se trouve à 7 metres ( en 50² )du coffret ou se trouvent le multiplus / mppt / ccgx
Mes questions sont plus précisement les suivantes :
Puis raccorder directement le 2 eme MPPT au meme endroit que le premier sur le multiplus ?
Dois je modifier la position du bouton rotatif sur le nouveau regulateur ou la connexion au CCGX en ve direct selectionnera t elle automatiquement les meilleurs parametres ?
Merci par avance pour vos réponses/conseils
Having some issues while trying to update my firmware on my multiplus via the victron connect app (via USB dongle on PC), after restarting the app it says failed to detected please force detection, Which I do and that takes me back into a loop of trying to update and the update failing.
Ive managed to reset everything via the VE config tools app, but still on a back level firmware, I know thats not bad, but It means I cant change any settings, such as battery type etc.
Anyone offer any help on why im getting this error?
I do have an installation with an ET340 and ABB B24 energy meter on the same bus. The Cerbo GX only sees one of the meters, never both at the same time. The ET340 is used to measure a third party PV inviter while the B24 monitors total import/export (Grid Meter).
What can be the cause that only one meter is seen? I did change the address af the B24 to 2, no difference.
Why can only 2 energy meters be connected to a single RS485/USB adapter. This is extremely inconvenient.
Thanks for the feedback
I have red many Victron documents, watched webinars and also searched through the Victron Community but was not able to clearly figure out how a Multiplus II behaves if no assistent is installed. Would be great if someone could provide some informations.
- ACin of the Multi connected to the grid, no feed back to the grid
- Critical loads connected to ACout1
- One Pylontech US2000C and a Cerbo GX
- no PV, no MPPT
a) Will the Multi keep the battery always 100% charged?
b) Will the load on ACout1 fed from ACin or from the inverter by discharging the battery?
c) In case of a grid loss, will the load on ACout1 fed by the inverter and battery?
- Same as scenario 1 but additionall with PV and MPPT
a) Will the battery primarily charged by the MPPT and in case there is not enough sun via ACin?
b) Will the load on ACout1 primarily fed by the inverter by discharging the battery and in case there is not enough sun via ACin?
Actually I would like to set up a self-consumption system with backup capability and the possibility to charge the battery with an generator in case of a long lasting loss of grid. For this an ESS seems to be the right choice. But Victron says, that an ESS should not be used in case of "Off-grid systems - either with or without generator". That surprises me because a long lasting grid loss leads to a kind of "Off-grid system".
Hello, I have questions about the Multiplus Victron Energy. In the case of Victron Energy, the grid (backup source) and the battery pack are connected to the Multiplus. And the latter is who will manage this is two sources, that is to say, for example, if the state of charge of the battery reaches its minimum and the PV system can not feed the load, the Multiplus will feed the load with the grid. In my case (I work on microgrid systems and energy management systems) I have to do this management with an independent control system, that is the control station that has to start the battery charging and connect the system to the grid to feed the load. For this I have two questions:
Q1. Can I use a PLC to control the Victron Energie Multiplus so that it works either in charger mode or as an inverter?
Q2. Can I connect the grid directly to the AC bus to be able to control the grid relay directly with the PLC? I don't think I can control the relay inside the Multiplus directly with the PLC (please confirm this if possible).
Hello, I hope you are well. I am a research engineer and currently I am working on microgrid systems. I have two questions about Victron Energy products and I will be very happy if I find answers as much as possible. My first question is that in my work I have to make a laboratory prototype of a microgrid, then move to the part of energy management. For that I chose to make a centralized control, that is to say a control station which will control all the system (control of the switches on the load side and on the source side -PV/Batteries/ public network or generator). So the question is can I eliminate the power management at the Multiplus level (I can detail question 1 if it is not clear!).
The second question is about the product "Interface MK3-USB VE.Bus to USB", do I have to use this device to access the configuration of the multiplus or can I configure the multiplus even with the application or via web?
Although my idea of solar installation has always been off-grid, having grid, suplier installed the ESS assistant for my AC-coupling + DC-coupling system. I am not at all happy with this configuration and I am reluctant to be hooked to the grid. I understand the grid as the last resort, as if it were a generator. In other inverters such as the Sunny Island, the configuration in this sense is very intuitive, but at Victron I am reading dozens of documents, experts opinions and moralists that do not clarify the matter as I think it deserves.I would like to know which assistant or assistants can be configured to work in isolation with an ac-coupling + dc-coupling, using the grid as generator.I found a post where they recommend the following: - AC-Coupled PV Inverter Assistant + General Flag and Generator Start/Stop -DC-Coupled Virtual switch - Dedicated ignore AC InputHonestly, if I'm asking, it's basically due to my ignorance and I totally don't know how these combinations work. All the best
I've recently bought a Victron Atlas Combi (12V 800W) for my friends from Ukraine.
Unfortunately the device came without a temperature sensor. The manual says, there must be one, temperature sensor type is specified as V.T.S. (Victron Temperature Sensor).
1. Will the modern temperature sensors for Multiplus/Skylla work with Atlas Combi ?: https://www.victronenergy.com/live/temperature_sensors
2. Is there a way to make the charger charge without the sensor (now it does not charge but shows no failure when no sensor connected and the jumper HD6 set to ON) ?
BTW. In Ukriane they have electricity now only at night for c.a. 4H (september 2022). Victron products are like blessing for them now. The goal is to run heating pump for few hours more. Atlas Combi, though an extra old device is exactly what should help them survive the winter.
The Multiplus II can control the output power of an inverter using the frequency: the higher the frequency the MP2 creates, the lower the output of the inverter. This works well with Fronius inverters.
Question: Does this also work with Hoymiles inverters? HM-1500 for example.
