Burnt neutral in AC in

I've been having problems getting my generator power to reach my Multiplus 12v/3000 inverter. I went to check today at the multiplus system to see if the wire had been pulled, but I found a burnt neutral in the AC in connection. How could this have happened? How do I fix it?

Are Assistant Programmable Relay 'Switch conditions' evaluated as AND or OR?

I want to make sure I've configured my MultiPlus' correctly. So far when I've used more than one 'Switch condition' all conditions were natually met so I still don't know if selecting multiple conditions are 'AND' values (all must be met), and not 'OR' (any combination).

I was able to verify the 'Extra drive options' are OR values by selecting 'in case of general system failure' and the assistant worked despite being selected. I've created quite a few programable relays to ensure they're evaluated as 'OR' values.

I suppose I can add another programmable relay with mutually exclusive switch conditions. I'd rather know from the source how they are supposed to behave rather than assume and potentially get tripped up on a new firmware release.

MultiPlus Compact Schaltet nicht auf Netz um

Liebe Leute,

bin seit kurzem Besitzer eines MultiPlus Compact 12/1600/70-16.

Nach langer Problemlösungsversuche hier meine Frage:

Er schaltet nicht auf NETZ 230V um. Die Einstellung für die "Ignorieren AC-Eingang" Funktioniert aber sobald mehr Leistung entnommen wird, klickt es paar mal und fertig, bleibt auf Batteriemodus.

237V 50HZ liegen an. (Ist Netzstrom kein Generator oder Ähnliches)

Kennt jemand das Problem? Ist der MPC vielleicht defekt oder ich nur zu Dämlich? :)

Bin um Hilfe Dankbar...

Connection error while updating firmware Multiplus compact???

Who can help, because similar topics seemed to be unanswered.

I‘ve tried to upgrade the 2606413 firmware of my Multiplus 12/70/1600 to firmware 2606482 for ESS and to connect the Bluetooth dongle.

Followed the steps precisely but at connect part 2 I get “Error connecting. Please try again!”

The Multiplus was disconnected from the color control. Then the dipswitch settings were re-programmed (DS1 was on, now off and DS2 was off and now on) followed by switching DS8 from of to on and off again to store.
Power was removed as mentioned in step 1.
MK3 to USB was connected via COM4 and working.

I found that when I switched the Multiplus of (step 1) and on again while connected to the MK3 the unit doesn’t turn on and there is no connection at all.
LED’s remain off as well.

When I switch the multiplus off with the MK3 cable disconnected and then switch it on, it starts in inverting mode with the green light on.
However, then I get the connection error.

I tried both ports on the Multiplus; doesn’t matter.

Hope anyone can help!

Multiplus Compact 12/2000/80-30 230V: came with firmware 2608430, should I upgrade? And to which version?

As per the subject.

I have already registered on, reviewed the Changelog[1] and read the associated documents[2][3], and I understand that I need a 26084xx file; on, I can see that:

a) There is *no* 2608430 file, so I understand that, after I upgrade, there is no going back to the version that came with the equipment (unless I can download or back it up from the equipment itself?)

b) The only versions I can see are 2608433, 2608459 (these, located in separate subdirectories) and (in the main directory) 2608485; the latest version (486, as mentioned on the Changelog) is not available for my equipment (ie, there is no 2608486.vff file available), despite being available for very similar ones (eg 2609, which according to [3] would be a MultiPlus 12/3000/120-16). Any reason for it not being available for my equipment?

c) Between 2608433, 2608459 and 2608485, which one should I install?

Thanks in advance!

Victron Multiplus Compact best setup in a motorhome?

Hello everyone,

I'm installing a Multiplus Compact 12/2000/80-30 230V in my motorhome, and would like to validate my planned setup with y'all.

The Multiplus is connected to a bank of 3 parallel LiFePO4 12V 100Ah batteries, thru a 300A megafuse on the positive cable and a BMV712 shunt on the negative cable, and as soon as I finish upgrading its firmware and configuring it, will be connected "in between" my motorhome's external AC cable -- the plan is to cut the cable at the point it comes in from the street, and the part coming in will be connected to the Multiplus "AC IN", and the part going into the motorhome will be connected to the Multiplus "AC OUT".

The idea is to be able to use the Multiplus charging and automatic transfer switching capabilities).

What do you think?

Thanks in advance,

-- Durval.

Quattro AC power in from micro inverters

I have a 12v system on my boat which has

victron Quattro 3000 120

1200 ah of AGM batteries

6kva diesel generator

900 watts of solar panels with mppt going to the batteries.

I am putting another 1000 watts of solar on the boat.
Is it possible to put micro inverters on the new solar and feed it to one off the Quattros AC inputs?

Will the Quattro use the 1000watts AC in bypass mode and effectively have 3900w output?

What will the battery charger section of the Quattro do with just 1000w of AC power?

VE Lithium Battery Bank, Which BMS to Use?

Hi All,

I appreciate that this question may come down to preference, but I would greatly appreciate anyone's input on this if possible. My dad and I are currently installing the VE setup I've purchased for my liveaboard, which includes:

3 x 100ah Lifepo4 batteries

1 x Multiplus 12/3000/120

1 x BMS 12/200

1 x BMV 712 shunt

2 x Power In Bus bars

1 x Cerbo GX & Monitor

1 x Standard 105ah lead acid starter battery

70amp alternator

The Victron setup above was recommended to us by the agent who I purchased it from. Since then we have done a good bit of research on the Victron setup, and we are now questioning whether the BMS 12/200 is the best option for our setup... Would anyone recommend the Smart BMS CL 12/100 and or the VE.Bus BMS along with the Cyrix Li Ct?

The Smart BMS does not appear to limit the current draw of the house batteries which the BMS 12/200 does appear to do. The Smart BMS also appears to offer better protection to the starter battery..

Can anyone weigh in on their experience or opinion of these BMS options?

Cheers, David

Is it safe to turn off a MultiPlus under load via VRM?

I have a MultiPlus 24/2000/50 connected to a VenusOS device which allows me to connect to it via VRM.

About the only thing I will be using with the inverter is a small air conditioner that uses 420W while the compressor is on.

Is it safe to connect to VRM and tell it to turn off my inverter while the A/C is running? This is just incase I end up being away from the trailer unexpectedly for a few hours and realize I left the A/C on.

DC Leakage via Protective Earth Conductor

I'm have this weird problem that during a no-load condition with an Smartsolar MPPT charging, I'm seeing a phantom load of around 22 W that doesn't seem to exist. The MPPT is mounted in a cabinet along with a Multiplus, and the whole cabinet and both devices are tied to a protective earth bus bar, which is bonded to battery negative, aka before the SmartShunt in the system. The Multiplus and the MPPT are then grounded on the load side of the SmartShunt. I also measured the current in the earth conductor, and it's around 1.4 A, which correspond quite well to the 22W phantom load on the system (12V system). There's also an equal discrepancy between the battery + and - conductors of the MPPT. So, is there an issue with my MPPT charger, or should I bond the protective earth bus bar on the load side of the SmartShunt?

Rest of system unaffected. Doesn’t seem to correspond to anything unusual… no large loads at the time, etc. We’ve had storms the last day or two, not sure if this would be a factor.

Ripple Warning On Shore Power

I am having a problem that I don’t understand. When I am plugged into shore power and use a high drew item like the microwave (12.5amps) or air conditioner I am getting a low battery, battery voltage ripple, and sometimes an overload warning from the Victron App.
It’s strange because I don’t get any warnings when high draw items without shore power, everything seems to work fine when the power is coming from the batteries through the inverter.

At first, I thought maybe the shore power source may have not been providing 30amp’s and the inverter was kicking in to make up the difference. But it is happening anywhere I plug into a 30amp service.

Below is what I have installed.

Multiplus not connecting to Onans HDKBB-6880 Generator

I have a Multiplus 12 | 3000 | 120 - 50 | 230/240V , I recently purchased a Onans HDKBB-6880 diesel generator which i have just installed . the problem i am having is the Multiplus won't connect to the Generator unless I put an external load on the generator 1st.

The generator is producing 232 volts but until I introduce a load the output of the generator the Frequency on the multi meter shows as over 100hz, once the load is introduced the frequency stabilizes at 50hz.

Can the Multiplus be set to create a load on the Generator prior to full connection.

The only change was ESS set from "Keep batts charged" to "Optimized with battlife"

By returning it to "Keep batts charged" does not help

Accepted frequency ranges of MultiPlus/Quattro and effect on charger, pass through and AC2 output.

What is the frequency range if the "Accept wide frequency range" is not checked ?

Does this apply only to the passthrough mode, or the charger as well ?

What happens to the AC2 Output ? Is that in parallel with the passthrough mode ? I.e only active is AC in and out are synchronized ?

I found this is the manual . Doesn't specifically related to the "Accept wide frequency range" though.

Input frequency range

Input frequency range accepted by the Quattro. The Quattro synchronises within this range with the voltage present on L1-1 of AC-in-1 (priority input) or L1-2 of AC-in-2. Once synchronised, the output frequency will be equal to the input frequency. Adjustability: 45 – 65 Hz; 45 – 55 Hz; 55 – 65 Hz

I noticed that I have a permanent power on the 4A line when the charger no longer has any power. From this I conclude that the starter battery is charged with the lithium battery in the situtuation without external charge power. Unfortunately, this is a problem for me because the BMS can't intterupt this.

Quattro shutting down when Lithium batteries are full

Hi I have a Quattro that I have just replaced the Failing AGM battries with 4 24v 100Ah batteries wired in parallel and changed all settings as per Victron specs the problem in having is when the batteries are full the Quattro is completly shutting down and restarting without any alarm.

my observations are that the dc voltage starts to climb and when it gets to approx 30v it faults out, I,m wondering if the bms in the batteries is disconecting causing the spike in voltage causing the inverter to trip.

if so is there a work arround for this? the batteries are standalone not connected to the inverter, im using the standard Victron LifePo settings which is lower then the batterys recomended im pulling my hair out here any help would be appreciated thanks.

Ok I disabled the charger in the Quattro and am charging off the solar and is cutting off as it should and not spiking the voltage the problem is the quattro pushing the voltage up to 30v then tripping any ideas?

MultiPlus 48/5000 stuck on Mains, Bulk/Absorption, and DC voltage fluctuations

I recently replace my AGM batteries on my Victron Multiplus 5000/48 with 2p16s LiFePo4s. The system worked as intended the first day charging from solar panels and inverting. Since then, it would just stay on Mains (not inverting) and shift from bulk to float with the DC voltage fluctuating between 52v to 59v. I checked voltage at the battery terminals and it was a constant 52.6v. On the Color Control and BlueSolar Charger MPPT 150/70 it would show the wild swings in DC voltage. I tried switching the Multiplus off then on. After switching on it would go into inverter mode for about 10 seconds (DC voltage stable) and then would switch to mains and bulk and DC voltage would fluctuate again. I've checked the cables and battery connections and they're all okay. I've tested with loads disconnected. I also tried changing the Absorption and Float voltage settings to no avail. Any help or suggestions to a solution would be greatly appreciated.

This is my device list:

MultiPlus 48/5000/70-100

BlueSolar Charger MPPT 150/70 (VE.Can)

Color Control GX


32 x 280Ah LiFePo4
