Single Phase Charging/Supplying in a Three Phase System possible?


Hello together,

we installed a Three-Phase System in a Truck for sewer rehabilitation.

Following Components are in the system installed:

3x Quattro 24-3000

1x MG Master LV 1000A

4x MG HE 24V/200Ah

1x Cerbo GX

1x DMC

1x Battery Protect 220A

1x Fischer Panda 8000x 3ph 400V with CI-Interface

Now my customer wants to have the option to charge the system in his vehicle hall with 230V 1ph. I tried to configure this with the VE.Bus System Configurator but failed.

I heard of a possible solution in the online-training at victron professional to configure a three phase system with a 1ph 230V supply and a 3ph 400V outcome at the inverters.

Is there anybody who can tell me if it's possible (and how to do) to combine a solution using the ACin #1 (of only Inverter 1 for example) to charge/supply with 230V and alternatively using the 3 x ACin's #2 of all Quattros together for charging/supplying the system with 400V?

Thank you very much for your support!

ESS, why the Battery is used for an AC load ? which does not go through to the multi plus !


One question on the ESS and the AC load from Grid.

Previously I had a question with the ESS and an energy meter that I have exposed here. Is resolved

Now I don't understand why the ESS used batteries to supply energy to the load located on the Grid and which does not go through to the multi plus ?

The multi only provides critical charges via the AC1. The load like heater are only on the Grid.

I will empty the batteries !!! justo to turn on the heater !

Why does the multi supply the AC loads knowing that I have a grid ?

In the ESS parameters : no injection and Grid value at 0 watt.


Thanks you.

How to change owners of Victron CCGX?

Good day all

I have resently got a easy solar inverter with a coler control. Unfortunately the system was already registered on the vrm portal and do not have access to the portal for that specific CCGX unit

Who can advise me to remove it and change ownership of the portal ID. I find it on a regular basis where the installer registered the product and the system falls in new hand and no one can access the vrm portal

BMV-702 voltage reading

I have a Victron-702 used in a solar system, 640W solar panels, 60A MPPT controller, 2 x 200AH batteries, wired for 200AH @ 24v. My problem is that the Victron consistently under reads voltage cf controller. eg controller 28.4v cf Victron 27.6v, this creates the problem that the batteries never reach 100% capacity according to Victron. I have checked the true voltage with a multimeter and controller always shows correct voltage. Does this indicate that the Victron has a fault?

Carlo Gavazzi requirement: 3 phase, individual phase balancing OVER 100Amps - has anyone done this?

Hi Victron Genius's! I am in New Zealand where the revenue metering is done on a PER PHASE basis - not like the rest of the world which seems to be Net Metering.

For ESS installations below 63A we install the ET340 and the system runs along nicely.

However Lately we are getting mor enquiries for larger commercial systems where the mains are over the 63A limit and often over 100A per phase...

QUESTION: Is there a Carlo Gavazzi metering solution we can use?

Or do we have to try to extend the CTs.. and put up with a 100 A limit on the 100A:5mA CTs..?

Victron Multiplus 12/1200 does not charge

Dear Community,

i have a fairly new Victron multi 12/1200 (charged 3 times with it already) and I run a LiFePo4 200 Ah with BMS in my camper. Now all of a sudden, the charger Relais clicks when I plug external power in, but the Relais flips back out and does not charge the battery. Temperature is above 7degree and the votronic booster charges fine, so the battery is not the issue. I did not change the settings either after it initially worked nor did I fuck up the wiring... also, the settings fit the German power grid and leave enough room for

Quatto indicator low battery

Hello I need help not the manuals! I'm desperate! It turns out that this morning we miscalculated and we have used up all the batteries. We have run out of energy. We are off the grid. We have no alternative to energy.

The batteries began to charge but the electricity did not return home. I have been touching in the app where the programming is and I think that the error code is not eliminated in the Quatro device and the indicator of low batteries continues flashing but there is 64% of the charge but The electricity is not coming home and I am on the verge of an attack. The food is going soon to the trash and we don't have water either because it goes through the electric pump.

Does anyone know what I can I do in the programming so the quatro returns to its programming and does not continue giving low battery error?

Has anyone had this problem?

Thank you

All seems ok except for UPS function which does not seem to work when switching on and off from grid; basically all load gets disconnected for less than a second. Load on the quattro's is less than 50%.

If i switch to single Quattro and monophasic, UPS function works ok.

Single phase ESS in a three-phase system - Values not making sense?

We require some clarity on the following phenomenon:

Single Multiplus-II 5kVA installed on L1 in a 3-phase house. ET340 3-phase meter is utlilised since we wanted to measure consumption on other two phases (L2 & L3) for design of future expansion options.

9.6kWh Pylontech battery bank and 4.02kWp on a SmartSolar 250/70.

See attached screenshots:

1. No input from inverter to show meter reads correctly on L1, L2 and L3


2. Multiphase regulation set to "Total of all phases"


3. Multiphase regulation set to "Individual phase"


What we would like to know is how is it physically possible for L3 to have a negative value regardless of the Multiphase regulation setting when the inverter can only supply L1 with no other equipment on L2 and L3 that can generate power or export?

Customising discharge rates

Hi guys, I have a colour control GX running 3 Quattros and 60kwh (soon to be 90) BYD batteries. My situation is a different one in that we have a lot of dirty power issues and a huge amount of electrical equipment. I would like to customise discharge to a maximum of kwh at nighttime - relying on the grid for the remainder of operations.

I also want to make sure the GX jumps in to save low volatge issues that I seem to get daily.

Right now the batteries get sucked dry and then my equipment ceases every time there is a dirty power issue from the grid.

How do I go about programming something like this?

Thanks kindly,

MultiPlus Compact turns off when connecting network cable to MK2 USB adapter

Recently the AC input plug to which my MultiPlus Compact is connected stopped working for a reason that I have not yet identified. The inverter continued to work as long as the batteries (solar-charged) had energy to supply.

I connected the MultiPlus to another working AC input plug, and the situation seems back to normal except for one thing: when I connect the RJ45 ethernet cable to the MK2 USB interface, the Multiplus turns off (all LEDs turn blank and I can hear a relay switch) as if I had switched it off with the button. The moment I unplug the network cable, the MultiPlus turns back on immediately by itself.

This happens even when the MK2 is to connected to a USB port.
I tried replacing the RJ45 cable, the problem remains.
This does not happen if I connect the RJ45 cable to the Ethernet port of a computer.
I opened the MK2, it looks brand new with no trace of anything melt or burnt, no loose connection. Likewise, I see nothing worrying when I open the front of the Multiplus.

What could cause such a behaviour and what can I do to identify the root of the problem?
I suspect the problem lies in the Multiplus rather than the MK2, because it would be an odd coincidence that the MK2 stops working just after the recent events (it was connected when the AC failure happened).

Any idea?

We measured the voltages and on the plus side we had 22V and on the minus almost 0V! Do you think that we can eliminate this leakage by installing one big resistor maybe?

Monitoring suggestion: Cerbo GX vs (MK3-UB plus VE.BUS Smart Dongle plus Smart Battery Sense)?


I am narrowing down to an overall system design for my RV that will consist mainly of the following components:

+ MultiPlus Compact 12/2000/80

+ SmartSolar (or BlueSolar) MPPT 100/20 (12/24V-20A)

+ NoName - Lithium Iron Phosphate Battery 12V 200Ah with active BMS

The end result should be monitorable and configurable from an iPhone or Mac. As far as possible I would like avoiding the installation of control panels for this time being.

Also, the system should take in care of both leisure and starting battery charging and status.

I had in mind 2 solutions:

A) Point to point - Accessed/Managed only with VictronConnect

+ MultiPlus Compact 12/2000/80

- Accessory: MK3-USB interface (for cable configuration/monitoring on Mac i.e grid current limit)

- Accessory: VE.Bus Smart Dongle (for Bluetooth monitoring of the Inverter/Charger/Battery on iOS and Mac)

+ SmartSolar MPPT 100/20 (12/24V-20A)

- Accessory: Smart Battery Sense (for propert charging and Bluetooth monitoring of the MPPT/Battery on iOS and Mac)

- NoName - Lithium Iron Phosphate Battery 12V 200Ah with active BMS

- Accessory: ?

B) Centrally coordinated - Accessed/Managed with VictronConnect/VRM

+ Addition: Cerbo GX

+ MultiPlus Compact 12/2000/80

- Accessory: VE.Bus Cable Connection to Cerbo GX

+ BlueSolar MPPT 100/20 (12/24V-20A)

- Accessory: Ve.Direct Cable Connection to Cerbo GX

+ NoName - Lithium Iron Phosphate Battery 12V 200Ah with active BMS

- Accessory: ? Some kind of connection to Cerbo GX

There is an evident extra expense for the Cerbo GX, at the same time it looks like I am saving using a BlueSolar instead of SmartSolar and also not needing a VE.Bus Smart Dongle and Smart Battery Sense

There is a gain i ncentral management and expansion possibility using the Cerbo GX also being able to connect it to tank levels monitoring and so on.

I am in doubt of the following:

is the MK3-USB interface is still needed to program the MultiPlus ?

How should the leisure 200 Ah be managed from the Cerbo GX?

How should the starter battery be managed from the Cerbvo GX

Are there missing components in the picture?

Any expert eager to comment on the two a) b) setup and maybe pointing out missing pieces? (like shunts, bms, lynx distributor..) .I am also concerned in how much the managing system (Cerbo GX) would consume.

VE.Bus BMS and MultiPlus / Cerbo combination

I have wanted to be able to control the Multiplus via the Cerbo, but the VE.Bus BMS and VE.Bus BMS Assistant on the Multiplus block the Cerbo from changing the invert state between On / Off / Invert Only / Charge Only.

Having done some testing I have reverted to the 2-Wire BMS assistant on the Multiplus and wired the VE.Bus BMS Charge Disconnect to the Aux 1 port and Pre-Alarm to Aux 2, using an Inverting remote on-off cable. I am now able to change the status of the Multiplus from within the Cerbo Screens. The Cerbo correctly shows the VE.Bus BMS status through the relevant MultiPlus screen. Both disconnected at the moment.


I also had a VE.Bus Smart Dongle and found I could modify the status of the Multiplus via my phone as well. When status changed the Cerbo reflected that changed status. So I have a system working as I would like, but not using any functionality of the VE.Bus. I guess I could have achieved the same thing using the smallBMS with pre-alarm.

What I was wondering is if anyone can advise what functionality I might have lost by disconnecting the VE.Bus BMS from the VE.Bus?

I have noticed during my testing today that there is no Alarm or Error that is logged when the VE.Bus BMS signals load or charge disconnect, simulated by disconnecting the signal. The Cerbo clearly isn't triggering on the change of the Multiplus VE.Bus BMS status. I am not sure if it ever did alarm/alert when the VE.Bus BMS was connected via the VE.Bus port to know if I lost functionality. I do know a few weeks back I had a VE.Bus BMS Charge disconnect event and never saw anything on the Cerbo.

Hope people find this useful and it would be good to understand what functionality has been lost by taking this approach and not have the VE.Bus BMS communicating on the bus.
