Is there a way to open the AC-input relais on MultiPlus-II by a command submitted to GX-device or with an input signal on MultiPlus-II when using ESS- instead of a virtual switch application? I would like to avoid placing an additional motor-switch or relais in between grid and MultiPlus device.
Hello Dear Community and Staff,
We have a 3 phase system with Multiplus 2000VA inverters, Smart Solar Chargers, a CCGX and a Battery monitor BMV712. We want our system to use the grid only when batteries SOC is below 50% and when Load exceeds 1600W after a couple of seconds.
Somehow the Virtual Switch is doing its job for the battery SOC condition but not for the load condition, we tested with a constant 1800W for 60 seconds and the AC inpunt won't come in. This is important for us, as some loads in the house come in really fast and take the inverter inmediately to overload.
Does any have had this problem? what could be missing?
Please finde below some screenshots of the Virtual Switch configuration at VEConfigure for L1 Inverter.
Hello, I have a problem with a three-phase installation consisting of 3x Multiplus 48/5000/70-100. It is an off-grid installation with a Pylontech lithium battery bank and SmartSolar controllers, all controlled with a Cerbo GX through DVCC. The system works smoothly off-grid. But a three-phase electrical network connection was installed in the sector, and with this the house was connected to the network and increased consumption with the intention of using the electrical network.
The idea of the new operating mode is to use the solar system as a priority (and complete backup in case of grid failure), and to leave the grid as support at times when the loads exceed the capacity of the inverters or the batteries are low. For this, the virtual switch was configured in "Ignore dedicated AC input" mode, according to manuals this instruction must be configured only to Master L1 and when doing it in this way the instruction really works but only responds to the values of L1, and when it is exceeded the power (4500W) in L2 or L3 the system does not transfer, generating an overload in inverters and cutting the system. When configuring the virtual switch with the same instruction to ignore AC input in each inverter, the instruction of (no) ignore AC input definitely does not work or operate in any way, the AC input is always ignored and does not transfer at any time.
Is there a way to ignore AC input in 3 phase system and work for all 3 phases, and the system can immediately switch from inverter to main when the loads for any phase exceed the established power limit? (All devices are with updated firmwares.)
I have 3 Multiplus 24V/3000/70-16 configured as 3 Phase System, all are switched in a group. Firmware Version is 2612430 on all 3 ones.
I tried VS and the assistent to do not ignore AC input when the loads are higher than 2400W for 5 seconds. This works only for L1. When the loads are higher than 2400W on L2 or L3 the system does not switch to AC input. I tried now for 2 days, an i can´t figure it out. Maybe i am to stupid :-(.
Can somebody help me.
Tank you very much
I have a customer with:
- MP-II 3000 48V 30/50
- 4 x Pylontech US2000B
- MPPT 150/60
No GX device, no data connection, other than local VE-bus and Bluetooth
It has access to a mains supply available at certain times of the day (L1).
It all worked well, for about 18 months, then it ceased selecting the mains supply via the Virtual Switch. Customer believes it was after one of the firmware updates.
Please see the below screenshots and advise?

Please advise how I should load a firmware version from (say) April 2019?
I did some searching but did not find a response to this specific question. I have been using the monitor for grid failure functionality for quite some time and I am pleased with it. I have now been experimenting with the virtual switch features and in particular the one to ignore AC input when SOC and AC loads meet proper conditions. However, I get alerted when the shore power is cut off by the virtual switch rather than an issue with the grid. I would prefer to only get alerted that shore power is lost during periods when I have AC input on. Is this possible? (Maybe I am missing something obvious.)
Hello everyone, I would like to know my system a little better and I am investigating to find out which would be the best configuration option for my needs.
I currently have my system configured with the Virtual Switch function in "ignore dedicated AC input" mode.
Basically I have configured when I want my inverter to connect to the electrical grid and when I want the batteries to be disconnected when reaching a discharge limit. Nothing more.
I have never tried any of the wizards that are included in VE configure and I am curious if these wizards would allow me to do some things that I cannot do with the Virtual Switch.
In particular I am interested in the ESS assistant.
I have read information and documents on the Victron website about this wizard and I know that it is used for energy storage systems. In my case, I have several batteries to store energy during the day and that I use to charge the house at night.
My question is: Are there any benefits to using the ESS wizard that I don't have using the Virtual Switch?
Ve Configure does not let you use a wizard if you have the Virtual Switch activated, so I understand that each option must have its own characteristics. This is what I would like to know, what differences are there in using the Virtual Switch and the ESS assistant in practice.
As I have said before, I would like to know a little more about this and to know if I am really using the best option available.
Thank you very much in advance.
I have a really old victron multiplus compact 2000. I have tried to get the alarm output to drive a relay that will start a generator. I have had no luck in ever getting the alarm output to trigger the relay. I know the most likely option is that I have done something erroneous, but I can't help thinking the output is not working. I have programmed a lot of different options to debug the issue using VEConfig. To the very least I would expect checking the "invert VS" button would make the relay switch, but no.
What if the previous owner shorted the output, would that damage it? Any way I can see if has been shorted? The connector does not sit straight, seems like someone has used significant force to fasten the wires. What is the likelihood off damage? If damage is likely, have anyone tried repairing it? I am well above average on electronics and soldering, but I still need to know what to do.
I have connected the right alarm terminal to battery GND. The right terminal is connected to on terminal on the solenoid on the relay. The second terminal on the solenoid is connected to 12V battery. The intent is that the alarm output will allow current to flow in the relay solenoid and switch the relay on. If I short the wires going into the two alarm terminals, the relay switches.
Any ideas? Please do not ask med to deliver it to a dealer. It is installed in a cabin in the mountains and the unit is really old. The motivation to dissemble it, transport it back and forth, etc, is really low. If I cannot get it to work myself, then the unit will never start the generator.
Anyone had similar issues?
I have a Solar installation with LiFePo4 Battery on DC input and Grid on AC input.
LifePo4 works with Bms. If I connect the Vebus BMS to the MultiPlus, I need to add the BMS Assistant.
If I add the Bms assistant, I need to select "no vs switch" instead of "Ignore Ac Input".
Without "Ignore Ac Input", I use much more current from Grid, and too less from solar ! It's uninteresting !
So, I need ESS. But for France, with a MutliPlus v2614-481, there is no ESS Mode without "togrid" mode. So I need to buy a Ziehl anti-islanding system, which is quite expensive for an unknow result. And the main Electricity Provider of France (EDF) doesn't help small producer as me to establish a mandatory contract of buying the "to grid" energy. Well, it's very complicated and I turn in round.
Why it doesn't exist an ESS mode, without reverting to grid ? Because with "Ignore AC Input", we can't benefit some ESS cool function as : "Maintain mode", planning for loading Battery on grid, Bms Assistant, and so on".
I'm so annoyed !
Filax 2, When the priority souce is unpluged (shore support) yellow light, no red fault light on. we are then switched to the alternative source (Victron inverter) the yellow light glows on together with the Priority Source fault light (red), is this correct and working correctly or is there a genuine fault
unser System besteht auf 12 Volt Basis, 2x 150Ah lifepo mit BMS, SmartSolar Charger MPPT, Victron MultiPlus C 12/2000/80
Wieso kann das System nicht dauerhaft am Netz 230V hängen und wenn die Sonne scheint wird einfach anteilig die PV Einspeisung durch das Netz ergänzt???? also zB.: 500 Watt Solar - 1200 Watt Verbraucher liegen an, 700 Watt wird aus dem Netz bezogen - und das ganz automatisch?
Das wäre doch logisch.. aktuell schaltet das System die PV Anlage einfach komplett weg und nutzt nur das Netz - und über die VS (virtuelle Schalter) Funktion kann ich ja nur einstellen wann sich das Netz komplett zuschalten oder wieder wegschalten soll - das ist doch quatsch.. dann beanspruche ich doch permanent die Batterien... oder ist setze die Udc usw. so knapp, dass das Netz permanent zu und wieder ausgeschaltet wird
Gibt es irgendwo - die Einstellung oder wenn es nicht anders geht einen Trick wie anteilig IMMER automatisch die Solarenergie genutzt die zur Verfügung steht???
Bin für jede Hilfe dankbar!
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 have a MultiPlus Comapct and I'm just about to start installing my new Lipo4 set up using none Victron batteries and BMS. I have realised that the Compact does not have the same remote switching capabilities as the full version.
I have been told that I will be able to use my bms to switch over to charge only on low soc and I would use a solid state relay on the incoming generator feed to stop an over charge.
Is this the case and would these settings be done by an assistant on the ve configure software?
Any suggestions and advice greatly received as I'd assumed that the compact would have the same functionality in this situation.
I have set up a virtual switch on my Multi 12/3000 (it’s the “Ignore AC Input” switch so that I can prioritize solar over the grid). Is there a way I can add a switch on the mobile app (like in the attached photo) to be able to simply switch it on/off? I don’t even know if that switch is for a Virtual Switch... but it would be nice if it were and I could switch it on and off like that.
The reason I would like this switch is because I have downloaded Parallel and Windows 10 trials on my MacBook and the trial period is almost up and I’m not really interested in buying these programs. However I don’t know if I want to leave this virtual switch on without any way of turning it off once the trial period ends... I saw the pictires of the switch and wondered whatit was and if it would work as I am hoping.

My system was installed by a third-party, but since then I've been unable to get a response from the company. I was given little insight into how the system works, so I'm learning from scratch. Any help is appreciated. I recently moved into an RV and some of the time I'm connected to Shore Power. When connected to Shore Power, I want to limit the AC-In and utilize batteries and solar as much as possible. Only when the battery SOC drops to a certain level, or when the AC Loads exceed a certain wattage do I want to use Shore Power.
Whether I successfully disconnect AC-In using the Virtual Switch or via the Programmable Relay, once AC-In is cut, I also lose all AC-Loads (i.e., none of my AC appliances work), though DC Loads remain. Once I remove the Virtual Switch/Programmable Relay settings, all AC Loads return, along with AC-In. The only way I've managed to obtain (most) of the functionality that I'm after is by using an ESS Assistant, which is expressly forbidden for RVs*, so I'd prefer to use other options if possible.
Since I did not setup my system and since it's setup in a tight space, I can't get into my Multiplus to verify the wiring, but I believe my AC Loads are wired to AC1-Out (my understanding is that AC2-Out only works when AC-In is present).
*Note: I will disable the ESS Assistant prior to disconnecting from Shore Power to alleviate the concerns with disconnecting an RV while on ESS.
Does anyone have any ideas as to why this is happening and what I could do to resolve this?
We are having trouble with our virtual switch "Ignore AC Option" in our 3 phase system. We just recognized a text dipslaying "not in phase" as it can be seen on the attached image regarding de VEConfigure Monitor. Any idea what does this mean?
270W solar panels- EasySolar 48/3000 (Multi) with MPPT 150/50- 4x200 Ah gel batteries in series for 48V . BMV 700 - CCGX Color control. No Grid feed in allowed . Grid available for AC IN.
I am having serious difficulties setting up ESS / Assistant with VEConfig.
When looking at what Virtual Switch can offer, I realize this is far enough for what I want to do.
1_ Use as much solar as possible to recharge the batteries ,
2- Set VS for Grid ACIn to come ON when batteries are too low (50 V) or when a heavy load is powered .
I have set up VS on VEConfig . All seem OK; I have "sent" the settings .
However, I do not see my Multi behaving according to the VS settings . Example . i have SET AC IN "ON" if more than 3000 W is requested , or if batteries get lower to 50 V.
Right now my batteries are 52 V, and my AC OUT loads are 500 w.
Until I solve the VS settings problem, I have my EasySolar "ACIN" breaker on "OFF" as I do not need , nor want any AC IN .
If I turn on the AC In breaker with these voltage / Watts described above, my AC In comes in ? It should not.
Did I forget something after setting VS on VEConfig ?
I have my Multiplus II using the virtual switch to ignore ac and use solar and battery power. This works well during the day when there is sun.
But I would like it to switch to bypass or ac during the nighttime when there is no sun. And save the batteries from being charged and discharged.
I was thinking of using an external time switch but how do I connect this to the multiplus?
I also have a raspberry pi running Venus OS if that will help.
I recently programmed the virtual switch on the easy solar 48/5000 for a generator remote start (Dedicated generator setting). I have the settings for the genset to start when the load is at 4500watts and battery at 45 volts. When testing we loaded the circuit and the genset kicked in at 4500 watts as programmed but the AC in didn't switch over. Would this be because the battery was still at a full charge (showing 100%) and was approx 52 volts when we did the testing? Or should the AC in relay switch over under the above conditions.
Thanks in advance.
Hi I have a victron quattro 48v 70amp 5kw inverter I am completely of grid with no sure power. I would like to have my generator to come on when the batterys get low. I have wired to the k1 swicth with the 12 feed to common and then switch wire to n/open. I have set up the switch via the configuration via lap top but yet the still wont work it like they just there for show. I set it for generator control and set the voltage and the percent when I wont it to come on but yet they dont do anything. Not sure if I have missed something.
Thank you in advance
I would like your help concerning the virtual switch that i used.
I select in the virtual switch this usage : drive aux relay (VS =ON) +ignore AC input.
And i would like to switch ON the relay when the Udc is under 46volts. Switch Off when thé udc is above 51 volts. If power more than 4200w connecter to AC curent.
I know how to enter the value on the software but i didn't find the physical aux relay on the multi ? And how wiring ?
Is the Aux 1 relay with + and - ? Or Aux 2 ?
Thanks for your help.
I understand any ESS requires Anti-Islanding relay. Does the Virtual Switch Ignore AC also requires it? My PV is connected to the MPPT to charge the batteries and I want the Grid only to charge the batteries in case the PV power is not enough or I have used a lot of power at night and I have depleted the batteries.
What is the impact of disabling the AC_1_in on a Multiplus II with the virtual switch in an ESS system?
I have two systems, each with a Multiplus II 48/5000. Each has a single Narada 48NPFC100. The battery is generally sufficient for my requirements, with very little taken from the grid. My consumption doesn't justify additional battery purchases. However, the battery goes into protection mode the moment the output current exceeds 100 A.
We have pretty unstable grid supply. If the grid drops when there is no solar input, the battery often goes into protection mode with an overcurrent alarm. If I switch off the grid input via circuit breaker before the grid drops (it is loadshedding, so pretty predictable), the battery and inverter stays up. So basically, the battery really doesn't like that moment between where the grid drops and where the anti-islanding relays open. Also, the battery then struggles to boot up the Multiplus unless there's an additional powersource (grid comes back or power from the panels).
My plan is to use MQTT with a scheduler to disconnect the grid a few mintues before loadshedding is scheduled to start, and to then reconnect it after loadshedding is over. Any reasons why I can't use the virtual switch to do so? The rest of the time I'm perfectly happy with my ESS setup - it is only when the grid drops at night that I have issues.
The internal transfer switch stopped working. The system was setup such that when the battery voltage reaches 48V for 5 seconds the internal transfer switch brings in the utility to power the loads. I loaded the ESS assistant settings in the inverter as an attempt to bypass however I don't see the menu options for the ESS on the CCGX. I also have no option but to advise the client to switch manually. I need some assistance to resolve this issue.
I have a system with 2 MPPTs, Quattro 5000 24V 50/70 and Color Control GX.
When I connect to the shore, I want to use energy from the solar panels in priority, and complement with the grid. I do not want the batteries to be used at all, i.e. no discharge of the batteries.
Using the Keep Batteries charged mode would be great, but ESS is not possible on a boat (why?) and I've no anti-islanding material. Using hub-1 v2 assistant only use battery voltage and will permit batterie use. Virtual switch is not enought intelligent. Etc...
If you have a solution for a boat, it would be welcome !
Thanks in advance,
I am having challenges with a self consumption model in the following aspects
1. after installation of EM 112 meter and activating Zero feed in , the battery module discharges providing power to both AC out #1 and 2 instead of providing backup only to Critical loads and leading to a complete outage.
2. If i deactivate the EM 112 with Zero Feed in- the PV yield is considerably low as its only feeding the critical loads .
I have a simple outcome,
Use solar to power up loads and charge batteries when available and if the loads go higher than X W amount use the grid .
Now using VS options doesn't allow you to use Assistants.
With the below I achived the following :
If the loads are > 1500W for 2seconds the Grid kicks in.
If the loads are < 800W for 2mins the battery AND solar takes over.
The battery conditions work as stated below as well.
Now the issue is :
When the grid is NOT required the system is using nearly 50% from batteries and 50% from solar (+-) .
When the batteries reach < 50% the batteries are charged from the Grid rather than the Solar.
PS : My solar array produces about 1600W
How can I maximize the use of the solar ?
Our system is as below
- 12 solar panels 250Wc Trina Solar
- 8 batteries AGM 250Ah each
- 1 Easysolar 48/5000
What we will like to do:
we have used the tool Virtual Switch to configure but when you download the configuration the system is showing that the system is "blocked" and no more power coming in/out of the easysolar.
also it's seems like ESS would be the right tool to use, but we don't have it in our assistant lists in VE configure, also how to deal with country code and other parameters ?
here below what's we have configured.
we are little confused as our victron dealer can't help us since two weeks we are asking support from him
I hope getting a clear answer and procedure from victron support.
the matter is urgent as we are currently on site
many thanks for the support
Good day. I am facing a problem trying tyo set some settings on ESS via VE configure.
When I reach the VE configures, Virtual switch tabs, the values are greyed and cannot be changed ?
I probably did something wrong, but cannot figure out what ! I tried many other changes, but still non editable ? Any idea ??
This is the tab where I cannot change the settings : "when loads higher than " .....
ESS is definitively the best solution for self consumption. But there are still a few cases where it is not allowed to be grid parallel or it is too expensive to install an anti islanding device. Furthermore there are situations where ESS isn't the best solution to use, e.g. in a camper. But these people often don't want to waste their solar power while being connected to the grid.
So what I thought would be nice to have is to combine the "Ignore AC" functionality with the "BatteryLife" from ESS. This would give the option to use self consumption while keeping the batterys alive. I don't know how complicated it would be to implement this (in ESS, VS, HUB1 or other) but it would be great to have full batterys every few days without always looking after them. There should probably also be an option in Venus OS for disabling this (enable charger). So when the camper leaves the campsite the battery could optional charge to 100% from grid before.
What do others think about this?
