Multi Quattro - Fronius Primo - ESS - Dedicated Virtual Switch

Good morning to the community

I have a lot of doubts about the my system and can't find any answers.

I have a system of:

10KwHof solar panels.

PV solar Fronius 8.2

80 KwH of lithium batteries connected via Can Bus

Actually I am using the ESS assistant

Unfortunately I am very confused because my dealer insists that where I live (Kenya) it is not recommended to use ESS.

But it seemed to me the only alternative to have the Feed In 0. He tried it with contactor connected to a relay, but nothing worked well.

In ESS is worked well for a year, then there were problems with the charger section of the Victron the Victron was replaced promptly.

Now after another year I have a similar problem when connecting the mains the multi makes a lot of noise it switches from Bulk to Passtrough and disconnects the mains and does this all the time.

If I manually disconnect the grid the system works perfectly as an inverter.

I was considering the dedicated virtual Switch, to physically disconnect as much as possible, but how will the feed IN 0 work ?

Any suggestion?

Thank you

Virtual Switch Ignore AC not working on Multiplus with Firmware updated

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.

Thank you!

Problem with Ignore dedicated AC input in three phase system.

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.)

'Ignore AC input' stopped working after firmware update MP-II 3000

I have a customer with:

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?


- Dedicated Ignore AC input (therefore no Assistants)
- Power Assist=on; current boost factor 2

Please advise how I should load a firmware version from (say) April 2019?

Monitor for Grid Failure when using Ignore AC Input virtual switch


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.)

Virtual Switch vs. ESS Assistant

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.

Virtual switch / alarm output not working.

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?

BMS, Virtual Switch, ESS. Why it's not easyer ?

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 !

Regards. Laurent

Einstellungen Virtueller Schalter oder andere Einstellung um IMMER SolarEnergie zu nutzen?

Hallo zusammen,

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!

Multiplus not switching back on with Venus GX


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?

Multiplus compact remote switching with third party bms

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.

Virtual Switch on/off toggle on mobile app?

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.

Losing AC Loads when Disabling AC-In via Virtual Switch or Programmable Relay


  • Multiplus 12/3000/120

  • 3 SmartSolar MPPT 100/50

  • 800Ah Battle Born Battery Bank

  • 1625 W Solar Array


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?

Virtual switch settings on VeConfig

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 ?

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.

Virtual Switch Easy solar

I recently programmed the virtual switch on the easy solar 48/5000 for a generator remote start (Dedicated generator setting).

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.

Virtual Switch with ESS

Short version:

What is the impact of disabling the AC_1_in on a Multiplus II with the virtual switch in an ESS system?

Long version:

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.

Prioritze Solar charging when using "Ignore AC Input" option

Good Day,

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 ?

What we will like to do:

  • Solar consumption priority, 100% self-consumption
  • Call to AC grid when the battery voltage drops to 75% for 3 minutes and loads exceed 2000W, then reconnection when the battery voltage returns to 90% and loads below 1500W
  • Battery protection: disconnect batteries when discharged at 35% , reconnection when 50%
  • No battery charge by the AC grid only by the batteries

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 ?
