How have 2 victron systems caught fire?

i would like to understand how 2 separately installed victron systems failed with devastating consequence.

first system was installed in 2019 - 5000w 110v inverter - a/c input burnt out - fortunately we smelt the burning wire and managed to disconnect the system before further damage occurred.

on our return to the uk in 2020 we had another victron system installed at a total cost of over £25,000. Including other items - by a victron approved dealer. This time it was a 5000w 220v inverter system

within a few weeks from completion this system failed catastrophically with a total and devastating loss of my rv, my friends rv, 3 cars, a horse trailer and nearly my home!

a forensic fire investigator has established the location of the fire and it was in the locker with all the victron equipment

Victron IP22 ABS parameters with LI-ION battery.
col asked · 2 hours ago

Victron IP22 ABS parameters with LI-ION battery.

I hae just purchased a Bluesmart IP22 charger. I have a lithium 120AH battery. The charger is 30A, however when I put it on charge at 69% it goes to ABS and only puts in about 18A. would have thought that a lithium battery wouldn't go into ABS until considerably higher charge. I have set the mode to LI-ION , which has its own algerithum, can anyone tell me if I am able to raise the charge rate or make it so that it doesn't go into ABS mode until the battery is in a higher state of charge. Thanks. Col.

Smartsolar MPPT 75/15 enough?

Hi guys. I am thinking of getting a second 275ah deep cycle gel sealed battery, at 12 volts. Thinking of using 3 100 watts solar panells connected in series, with a total Voc of 64 volts. My question is if a Victron 75/15 Mppt solar controller is a good option or capable of well charging and maintain that battery, in a 12V solar system?

Victron BMV 712 Smart battery monitor -- WTH??

I have the Victron BMV 712 Smart battery monitor (with two 100Ah BattleBorn 12V Lithiums), and while the monitor works great when boondocking, it does not work great on shore power; the readouts then make no sense: State of Charge (after a week on shore power): 13% (and dropping); Voltage: 14.44V; Current: -2.52A; Power: -36W; Consumed Ah: -186.9Ah.

Any idea what's up here?

Thank you!

Victron MultiPlus Compact 24V | 2000 VA | 50A - AUTO SOLID RED ALARM LED

Hello All,

I recently bought a Victron MultiPlus Compact 24V | 2000 VA | 50A from Northern Arizona Wind & Sun (

I followed the manual that came with the unit and plugged the device into my wall outlet.

Whenever I turn on power I automatically get a solid red alarm light whether the device is in "inverter" or "charger". I tried powering down the unit and providing power to it again to no avail. I am not sure (based on the solid red) where or what the alarm would be triggering.

I have attached images of my setup for reference. I have tried the unit with and without the temperature selection and seem to get the issue.

Connection Victron IP22 24/16 & Cyrix & Smart Hunt


I have an Landcruiser from 1983. 24V system, so double battery in the front as starter. I added 2 batteries in the back so have also 24V. These are household batteries.

I connected the Smarthunt on the starter battery pack, the Victron Cyrix relais in between the front and back battery pack. I connected the IP22 Charger in on the back battery pack.

My first question is: My alternator will charge while I'm driving the starter pack and when these are full the relais will switch to the household pack. But will this also be the other way around. If I'm parked and I'm connected with the charger on 220v. Will the relais also work the other way around and charge the starter pack when the household pack is full?

My Second Questions: I have connected the Smart Hunt to see what happens with the battery starter pack. If I'm connected to the 220 Volt in the back, I see in the front the Smart Hunt says it takes around 4-5amps form the front starter pack. This can't be the Cyrix Relais or the Smarthunt, as they take just 0.1amp.

I hope you can help. I don't want to be stuck in the woods with no power to start the engine :-)

Connecting victron 75/15 to existing fuse hub

Currently we have 640w of solar going to an mppt controller, in parallel, which goes to a 200ah lithium battery via a fuse hub.

Have just added 2 x 100w solar in parallel using victron 75/15 smart controller directly to battery.

We a drifter monitor which reads battery soc and amps etc of original 640w but does not include victron input. We think this is because its all linked to the fuse hub.

Our question is if we run the positive battery cable from controller to the fuse hub, can the negative be left directly on battery, or, does it need to go to fuse hub as well ?

Hopefully we can then get readout of combined input.

Any help appreciated

Please take a look at my final install

Attached is a schematic of my electrical power system on my 1977 Trojan F26 cruiser. Everything is working fine. BMV712 is networked with the MPPT100/30 and the 2 170W PVs are supplying adequate power to the 200AH LiFePo4 house bank. The original system powered by FLA deep cycle batteries.

Please take a look at the schematic and give me your thoughts. Much appreciated!

Updated Pylontech wiring

Victron has updated its Pylontech Wiring. See the picture below.


In the version before, the GND cable was connected to the negative pole of the DC Distributor.

Now they have excluded the GND cable at the negative pole of the DC distributor. So the system is not grounded at the negative pole anymore.

Why did they change it?

Is it true, that the negative pole of the Battery is connected to Ground over the case Ground, as this fellow says:

I have read in the MPPT manual:


So the MPPT should be grounded on the negative pole am I right?

power and current data missing: Smartsolar MPPT status in VictronConnect App

There is something very odd happening here, even though the system works ,there is no data for current and power in the VictronConnect App status the firmware has been updated to the most recent version .I am able to determine that the system is working because if you look at the history, all the data is there however status is zero.

Has anybody encountered this before?

What is the solution? comments and suggestions are welcome

The details of the installed system are

24x 250w Trina solar polycrystalline solar panels

1 X 5KVA Victron energy Multiplus inverter 48v 230V

1x 150/85 Tr VE CAN MPPT Controller

Cleaning Panels

I have 2 x 175 watt monocrystaline victron solar panels mounted on the stern arch of our yacht. We were recently hauled out in the yard for maintenance and were unlucky enough to be downwind of another boat that was spray painting epoxy and we have some fine windblown airborne particles of epoxy on our panels.

Can anyone recommend how to clean this off without damaging the panels and the surface?

Many thanks

Warum wird Strom aus dem Netzt entnommen?

Hallo Leute ,

mein ESS System funktioniert soweit sehr gut und zuverlässig:

Multiplus II 3kw

Color Control

2x Pylontech us2000B

Zähler netzt und Zähler pv

Nun kommt es immer wieder vor das Nachts oder am Morgen Strom aus dem Netzt entkommen wird obwohl der Akku noch mehr als 10% hat(10% ist mein Soc) . Wie auf dem Bild zu sehen ist wird Strom aus dem netzt entnommen obwohl der Akku 30% hat und zudem wird sogar noch aufgeladen.

Teilweise habe ich beim Laden den Eindruck das Victron nicht richtig misst oder Werte fürs laden als Verbrauch annimmt ???

Victron MPPT 75/15 Low PV Voltage Reported - Won't Charge

When I test the voltage at the controllers terminal screws it shows 66V (I'm using 3x 20W panels in series) - In the app its only showing 12.7V; which means my 12V batteries won't charge. If I connect each individual panel to the controller it still shows 22V at the terminal but still only 12.7V (each one shows the same) in the app. Is my controller toast?

Victron Multiplus 2 - bridging the neutral conductor
Hello everybody,

I'm planning a PV system with storage for a buddy and I've run into a problem ...

-Two-family house, two counters
-Common batteries
-Two Multiplus 2 500/70, one for each apartment
-Fronius SYMO 5kVA
-CEEE socket in the garage
-ESS, zero feed

So there is no problem with the independent power distribution to the apartments, but there is a problem with the CEEE socket. Here I would have to bridge N conductors from multiplus input and output.

Is it allowed?

I don't understand why the input and output are separated from N (?)

To understand my problem, I am adding the scheme I have planned so far. There is a mistake. Apartment 2 gets L2 instead of L1 from Fronius. And CEEE doesn't get an L2 from Fronius.
