Programming a time delay for switching the Multiplus 24/3000 back to grid?


is it somehow possible to program a time delay for the Multiplus (in an ESS system) before it switches back from battery to grid in case of an power outage?

In case of repair works on the grid I observed, that the first few minutes are often not stable and so the Multi switches to grid, back to battery then again to grid....

Is there a way to program a delay with assistants(?) with the goal to switch back to grid operation only if the grid is present continuously for about 5 minutes?

I have a hardware solution in mind but a software solution would be much more comfortable.

Grid consumption/injection through Modbus or MQTT

I just bought a MultiPlus II, a Cerbo GX and a battery with the objective to charge the battery during off peak hours and use it on peak hours.

I do not have the EM24, but as I'm a Home Assistant user, how can I supply to my Victron the grid consumption / injection through Modbus or MQTT? On the end my idea is to emulate the an EM24 through Home Assistant

Ground Relay Error 8 with Fronius IG Plus when switching back to grid

Hy All,

we deliverd a new Installation (Number 8) to an "existing" Farm House with a 3 - Phase ESS 15 kVA - Multiplus II System.

There is a Fronius IG-Plus 120-3 running for more than 12 years. So good for now.

Everything is working fine except we start the system in "Island" Mode with an Active IG-Plus. When AC Mains is connected, the System performs its Relais Test and after about 5 Minutes it is going to switch back to grid. Immediately, when switching back we get an Ground Relais Test Error 8.

When starting in Island Mode with a disconnected IG Plus everything is working fine.. after switching back to grid and connecting the IG Plus everything is working like a charm.

When coming from Grid with a GridLost, we also encounter the same problem when switching back to grid.
To make a conclusion.. When the Fronius IG-Plus is "Connected" (we switched off the system, because it starts working after 30 seconds.. so we could not test, if its a problem when standing by connected and producing), we get an Ground Relais Test Error when switching back to grid. (Always)

Whats wrong...

There is no mixed Ground and Netral (We have controlled that several times)

The Multis are showing those ERRORS:

Phase L1, device 1 (0) #44 0x820002
Phase L2, device 1 (0) #15 0x800024
Phase L3, device 1 (0) #19 0x800024

From the wiring...

AcMainSwitch - SwitchOverToGenerator - 100 mA 3 Phase FI - MulitplusII - FI-s to different Loads

the IG Plus is connected:
IG-Plus - LS 16A - FI- 003 A -To The MulitplusII Ac Out

As talking to Fronius Service Personal the have no Idea what s going on, because they say they do not connect Neutral to Ground ... so do we have issues with the 100 mA 3 Phase FI, or the FI 003A connected to the IG Plus?

The System is running the latest Firmware 487.

Unfortunately there is no Support from our Dealer, because they do not have the knowledge.

Have a nice day, always Sun and I hope to get some good feedback...

thank s in advance

Basic support Multiplus with Generator and grid connection

Hi, i am new and have a question if my plan is realizable. My plan is to use a Multiplus with a connected generator and solar power to reduce my grid load.

Currently i only have a grid connection with 3 phases and N, i live in Germany.

And my final solution would be this:

Use always the generator source to reduce the load. If the generator does not deliver enough power also use power from the battery which will be loaded from the solar panel and a Victron MPPT solar controller. If these two sources do not have enough power, use grid power.

This is my expectation of the ESS System:

I would expect that ESS of victron with Phase-compensation is able to handle my load and will reduce the grid consumption of my house to zero, as long as the generator power (max input configured in Multi) and Multiplus inverter power is higher than the load of the house.

Is this correct?

If yes, i would expect these devices in my system:

EM24 grid meter


MPPT solar charger


Wiring setup:

Connect the generator to the input of the multi and of course the battery to it. The battery will also used from a Victron MPPT to power up the battery with solar power. Connect the output1 of the Multi to one phase of my House, thats it?

It sounds to easy to be true.

I know there are a lot questions and maybe the headline is also not really helpful, but maybe one of you will help me to get better knowledge of this. Or will post some info where i can get the information.

Thank you very much.

Control of the Quattro power via output voltage when working in parallel with the network

I use a 3-phase offgrid system on 3*Quattro 48-10000 inverters and 4 4*LiFePO4 25.6 A*200Ah batteries (+ Gerbo-GX, GX Touch). I plan the next option for its further use. For the power supply of consumers, we use an 3ph/380V distant power line with 60-80 kW distributed along the line load for each phase (200 kW in total). This line is powered from a 10 kV/380 V substation on one side. During peak load hours, at the most loaded phase, the voltage can drop to the level of 190V. At the same time, the voltage in the other phases may be within the normal range. Temporarily, until the reconstruction is carried out, we plan to solve the problem by connecting our 30 kW device on the opposite side of the substation to maintain the voltage level during peak times. That is, when the voltage drops below the threshold (for example, 200V), the installation, working in parallel with the network, outputs energy either from the battery or taking it from another phase (if its voltage is high enough), raising the voltage to the desired (for example, 220V). The Hub-4 mode is similar to the one I described, but the balancing is performed according to the power balance on the Energy Meter, not depending on the voltage level at the output of the inverter. How can such a mode of operation be implemented? Thanks a lot

Victron ESS + ET112 = slow response


Recently I've installed ET112 grid meter on my system (which was using CT sensor previously) and I've noticed that the Multi is very slow on response to load. Currently my system looks like this:


The grid set point is set to -10W. The multi needs a good 15-18 seconds to stabilize after large load kicks in and another approx 15s to stabilize after load drops off. Check the video from VenusGX (the load is switched on at about 16s of the clip and switched of at 43s of the clip):

Is that how it should be? The difference in the load is just about 1.4kW, why is it taking so long to handle that?

Previously I was using CT Sensor extended with Cat5e cable to over 25m long, the system looked like this:


The response to load was pretty much instant. I've recorder video using the same load as on the previous one (load switched on at about 10s and switched off at 23s of the video):

The system need seconds to stabilize

Also you can see a clear difference on the Grid use graph from VRM portal:



As you can see, with CT sensor the system is very close to grid set point, with ET112 grid meter it is way off and hardly ever stay close to set point. The situation is even worst during cloudy day when PV power is fluctuating (you cen see it on my other youtube video).

Is it normal behavior? It looks like Multi can handle this load easily, the problem seems to be in the feedback from the grid meter (or algorithm when ET112 is in use). Is there anything I can do to improve this reaction time??? Please advice.

Kind Regards

Compatibilité Générateur et Multiplus II


Mon motel est connecté au réseau électrique et je dispose de deux GE de 30kVA et 20kVA respective qui sont sollicités selon le besoin avec un démarrage manuel.

Je souhaite ajouter à l'installation existante 24x325Wc en deux sous champs couplés à 2 MPPT 250/100, 28kWh de stockage, 3*3kVA Multiplus II en configuration triphasée .

1) Pourriez-vous me dire à propos de mon schéma câblage coté AC, si mes équipements et les utilisateurs seront suffisamment protégés de tous les risques possibles (contacts indirects, surcharge + court-circuit + défaut à la terre ) ?

2) Pour la protection AC-in des Multiplus II que j'ai choisi , Victron préconise 32 A pour chaque Multiplus II. La configuration triphasée permettra t-elle de foisonner les courants entre phases? ce qui en réalité me permettra d'avoir sur chaque phase plus de courant?

3) Mes GE de 30kVA et 20kVA sont assez vieux, est-il possible de piloter automatiquement la marche et l'arrêt avec la BMV700 ou le CGX?

4) Avec ces onduleurs on va « rétrécir » la puissance max disponible en tête de TGBT : 32 A avec SNE/GE et 32+13=45 A avec SNE/GE+Victron, alors que jusqu’ici ils étaient limités à 50 A (disjoncteur en tête du TGBT). Quelles mesures devrait -je prendre?

Generator and Multiplus II compatibility


My motel is connected to the electricity network and I have two GEs of 30kVA and 20kVA respectively which are requested as needed with a manual start.

I would like to add to the existing installation 24x325Wp in two subfields coupled with 2 MPPT 250/100, 28kWh of storage, 3 * 3kVA Multiplus II in three-phase configuration.

1) Could you tell me about my AC wiring diagram, if my equipment and users will be sufficiently protected from all risks (indirect contacts, overload + short circuit + earth fault)?

2) For the AC-in protection of the Multiplus II that I have chosen, Victron recommends 32 A for each Multiplus II. Will the three-phase configuration make it possible to increase the currents between phases? what will actually allow me to have more current on each phase?

3) My 30kVA and 20kVA GEs are quite old, is it possible to automatically control the start and stop with the BMV700 or the CGX?

4) With these inverters we will “narrow” the maximum power available at the head of the main switchboard: 32 A with GRID/ GE and 32 + 13 = 45 A with GRID/ GE + Victron, whereas until now they were limited to 50 A (circuit breaker at the head of the TGBT). What precautions should I take?

VRM grid lost alarm will not clear

I labelled my Quattro AC input 1 as ‘shore power’, then set up an alarm rule on my CCGX where all input labels (not available, grid, generator, shore power) were enabled.

When I disconnected my shore power, the CCGX and VRM gave me ‘grid lost’ alarms. I acknowledged the alarm on the CCGX and reconnected shore power but it took a reset to clear the CCGX, and I can’t clear it on the VRM.

I’ve tried deleting the rule and setting up a new one, re-labelling my input as ‘grid’ to see if that’ll clear it - no luck.

Any advice appreciated - would like to clear from the VRM.

No idea why the compensation setting in the venus gx is not working. Please help!!

AC L1,L2,L3 is connected to MPNr.1-ACIN, MPNr2-ACIN, MPNr3-ACIN. The system is useless. If the electric car is plugged in on one phase with 7kW it only delivers max. 2.4kW from one inverter, if no other loads are switched on. If someone cooks on L2, i only get 2.4kW from the inverter on Nr.2.

  • The battery will always be charged.
  • Maximum load on AC output-1 ≤ 7kW
  • Maximum load on AC output-2 ≤ 10kW (when the input network is available)

Unstable Grid with ESS

We have a 3-phase ESS system (grid connected) that is giving us grief:

The customer's house is about 2km away from the road, so the grid connection is very unstable and if any significant current is drawn, the voltage drops and lights flicker and other appliances turn off in the house.

The problem seems to be that when the load is large enough for the system to switch over to the grid, the entire system follows the grid voltage, rather than creating a stable voltage from the Multis.

Is there any way to make it so that the AC Out of the system is stable regardless of the AC In?

second battery bank on the MultiPlus grid ?

I have a working system with PV panels charging 220Ah/48V victron batteries connected to a MultiPlus providing AC, and optionally recharged by grid or (soon) a fuel generator. It is monitored by a VenusOS device.

I have the opportunity to have a second different battery bank (I already got them) and I would like to use it to extend the capacity of the system. The batteries are very differebt and I'd not want to connect them in DC with the first bank.

I wanted to know if it was possible to connect them on the AC local grid, possibly giving more power (sometimes the loads exceeds the first multiplus capacity). I'd imagine connecting them to a Quattro or Multiplus. Is it possible ? How can the second battery bank be instructed to recharge when the generator is up or on excess solar energy, and discharge when load is needed ? Is it automatic somehow ?

Additional question. When I have excess solar energy available, I'd like to power up some devices (heat up the water tank). Is there some way to do that ? At a distance (much like how the electrical grid sends signals over the wire to trigger the day/night mode)
