Tracking stolen Multiplus II GX

Good Day

I had a incident where they stole some stock from my shop.

Is there a way to track a stolen inverter if you have the serial number? Is it possible for Victron to flag the inverter and check to what account is it registered when/if it comes online? Is there a GPS in a Multiplus II GX? Can I add it to my VRM using a serial number (with the help of Victron if needed)

Orion-TR Smart 12/12V-30A Isolated Charger in non-isolated design

I want to use a Orion-TR Smart 12/12V-30A Isolated Charger on a new install in a motorhome.

The chassis and house batteries both use the chassis frame as ground. I want to simply tie the two negative sides of the Isolated charger together and use a single cable to ground. I can't see the need for two separate cables to ground. Am I missing something?

Or is this just a bad idea and I should get a non-isolated charger?

240V AC earth bonding to hull with 12/200 BMS

Hi. I'm working on a customer's boat with 2* Victron lithium batteries fitted with 12/200 BMS and 1600 Multiplus. I've noticed the 240V AC earth isn't bonded to the hull which is a requirement of UK narrowboat regulations. I assume it's not possible to bond to hull as start battery/alternator negative will connect to the LB terminal through this lead? Can anyone confirm this?

Also I've increased alternator size and trying to improve alternator charging as much as possible. Fitted a 100 amp mega fuse made by Littlefuse and getting around 70 amps max charging current. Wonder if there's a specific brand of mega fuse recommended or sold by Victron? - hoping to get closer to the 80 amps which should be possible reading the manual. Or is it a matter of trying a few different 100 amp fuses. The brand I can easily get are Littlefuse.

Hoping someone knows the answer. Thanks, Ed

AC current sensor & Shore power


I have a boat provided with Skylla TG, AGM batteries, Smartshunt and Phoenix Inverter. monitoring is made by Cerbo GX.

I have the issue that I can't see AC from shore on GX, due to the fact that skylla TG is not VE.CAN.

Is it possible to use AC current sensor normally used on PV inverters to do the job?

CANvu-GX does not update to show the status/operation of the Skylla-i.

From NZ Defence Force.....

I’ve got our new Victron Power System all together. Everything is working well except the interface between the CANvu-GX and the Skylla-i. I am able to get the information from the Skylla-i to come through the VE.CAN bus so it can be read on the CANvu-GX, but despite this the graphic display (the main reason I wanted the CANvu-GX) does not update to show the status/operation of the Skylla-i. (Display page example shown below – my setup only shows the Battery Information, not the AC input Power or any battery charging animation that shows the Skylla-i charging the battery bank).

Quattro/Multi Temperature Derating/Overheating behaviour in AC coupled mode

Just asking for some confirmation of what I believe I am seeing here,


This data is showing the quattro temp derating in AC coupled mode correct? The stepping of the AC output frequency and corresponding PV inverter yield coincides with the temperature warnings. The co-located MPPT yield is not throttled, the batteries are at ~65% (LA) and are in absorption, however the throttling is seeing the voltage not holding.

To me the device looks like its heat saturated, The PV Inverter reductions are too symmetrical and correspond with the temp warnings to be clouds.

It would be great if there was an indication the unit was derating or a internal temp sensor to verify.


So have a little more info from the site, the fans in the unit are slowly winding up then try to go to full speed and shutoff, this happens at exactly the same time the unit derates.

This leads me to believe that the power bus that runs the fans is exceeding its current and shutting down. Maybe by a self resetting fuse?

This unit runs a small island so sending the unit away will have problems.

It is possible for victron staff to look at any more internal data via the console to possibly determine the issue?

Error codes for victron 48/5000/70-50 multiplus

I have a victron 48/5000/70-50 multiplus running a Redflow ZCell which stopped working (No power from UPS circuit).

LED error codes - absorption, float, Flashing Invertor and low battery.

The system was reset a number of times with no change in status

The system logs don't show anything for the period of time the Victron was down for (2 days). It came back up again with no user intervention (suspect maybe a short power outage may have reset the system).

The BMS for the ZCell is on the UPS circuit and was down as well.

Any help would be appreciated to prevent this happenning again.

VictronConnect Improvement Requests - Offline mode, history metrics, dashboard, background mode

Hello VictronEnergy,

I'm a big fan of your products, I use the SmartSolar, the SmartShunt, the Phoenix Inverter and the LoRaWan Module happily.

As many before, I do also have feature suggestions to improve the usability of the VictronConnect App. I strongly believe you should invest more UI development resources into the App, as todays mantra is "mobile first" when it comes to building UIs. Don't get me wrong, I like the Apps structure and easiness of use, but I believe some crucial things are still missing for a happy user experience.

Many other such posts where made before this, so I'm sorry if there are a few duplicate requests.

Some of these other posts reported a flawed bluetooth connection and thus the app constantly needs to re-connect. I must say the App is most stable and very smoothly useable with Iphones. I tried several Android Phones and even with Victrons suggested Samsung Phones, the app runs far slower and not as smooth as with an Iphone.

Anyways the troubles of us VicrtonConnect users are still always the same, no matter which phone, the pain is only amplified on Android. So here is my which list:

* general offline mode

* more history metrics

* remove trends - replace with daily metrics

* Dashboard

* background mode

Let me elaborate in detail:

general offline mode


I think that's pretty obvious: I want to access my harvest history and all the relevant historic statistics, even when I'm not connected via bluetooth. I'd also like to see how "old" the history data is, so to speak, when was the last update.

Currently the "Status" tab is the Entry tab when connecting to the device. I would change this to the history tab and grey out the Status tab. When clicking on the status tab, the app could try to reconnect via bluetooth while still showing the history data.

I would consider this to be very important, with only little difficulty.

more history metrics


Some other posts mentioned some missing metrics, here is my wish list:

I'd like to see the current temperature (in Status) and also the historic values (Minimum, Maximum, Average).

I'd like to see daily average values for the solar power and the battery voltage.

I'd like to see the minimum, average and maximum power on the load port (on MPPT with Load connectors).

I consider this medium important, with only little difficulty. Not sure if the MPPT firmware would need updates to calculate the averages and send the temperature information.

remove trends - replace with daily metrics


I'd really like to see a solar, battery, and power output curve for the last and current day. more or less similar to the ones from the VRM but with a slightly higher resolution (e.g. every 15 minutes).

The trends functionality is rather useless, as many suggested before, as it requires the app to run constantly in foreground. I would completely remove this function.

I consider this to be medium important and medium difficult. This would surely require firmware upgrades and changes to the app.



When using multiple Smart Victron Products It would be fantastic to have a status dashboard which includes the most important stats into a single page. I'd like to see the current Solar Yield, DC Load Power, AC Load Power, Batter Fill level for my setup. I can imagine other metrics could be interesting in such a dashboard too.

I consider this to be less important and rather difficult as it might require multiple parallel bluetooth connections, which might be different on each platform.

background mode


This has been requested often, and I would request it once more. I'd like to have a background mode which leaves the bluetooth connection open even when the app is in background, so that the app doesn't need to reconnect and load all values again when switching to it.

I consider this to be medium important and difficult as it might be different on different platforms.


I understand it is a lot work to improve the app, build the firmware test everything and finally release it for multiple platforms. Some of these features might be very difficult or even impossible to add. But keep the mantra "mobile first" in mind.

I always recommend your products to friends and colleagues. It would be much easier if I could show them my real offline data with my mobile. I know there's the demo function, but still I'd like to share my stats with them, so they can learn how much energy they can harvest with a similar setup like mine.

ESS - 3 Phase system feeding back to grid


I have a 3-phase system consiting out of 3 Mulitplus 2 GX 5kVA inverters, a Cerbo GX, Pylontech batteries and 3 MPPT's.

When Inverters supply non-essential loads on AC Input side, the one inverter (L1) frequently feed power to the grid although I have a similar 1.8kW load on all three phases (3-phase element). The second inverter (L2) also pushes a bit back, but not as bad as L1 and then L3 is perfect. The Grid-meter (EM24) seems OK as when I deplete the batteries and it supplies the same 3 phase from the grid then all is good.

I have set grid feed-in to 0, and minimum set-point to 150W. Any additional items I could check?



I have tried to elaborate in another post, but seems I was just not descriptive enough and not found a solution.

Multiplus Stops Charging

I'm at the end of having any idea what to do next. Here's the setup...

Victron Multiplus 12/ 3000/ 120

Smart Solar MPPT 150/100


4 Battleborn 100ah Batteries

4 325W solar panels

This is installed in a 2004 Tiffin Phaeton

Connected to shore power

Solar is switched off for testing Multiplus

I am 67 and have an extensive electronics background

The Issue
The past several months, and it seems like this happened after installing a BIM in place of the charging relay, the Multiplus will run as expected for roughly 48 hours. After that, the charging stops, and batteries begin to discharge.

If I switch off the Multiplus - or disconnect it from shore power - for a few minutes, the Multiplus will begin charging again (Bulk @14.4v) for several hours and then drop to 13.56V. Eventually, I will see there is a zero amp draw, even with all our equipment running, it occasionally drops to -.5a for a short time and returns again to zero. Batteries are then fully charged and all 12v systems we have running are supplied by shore power.

It will stay this way for 36~48 hours and then, a 7 or 8 amp draw shows up, the system stops charging, and the process repeats.

Looking at the color monitor, the marching dots show the Multiplus is supplying power to all A/C. However, the batteries are actually supplying the power because they are quickly being drained.

If I disconnect from shore power, there is a change in the display. Marching dots from batteries to the inverter to coach outlets.

Reconnecting shore power, the inverter starts charging again. Marching dots to a/c load and also to batteries (bulk charging at this moment).

Smart Solar voltage: 13.22v
BMV Voltage: 13.02v
Shouldn't these be the same???

What I've Tried
For starters, I fully disconnected the BIM. The charging system seems to remain fully active for days. I reconnect it, and within roughly 36 hours or so, the Multiplus charging stops. At that point, I switch it off and on or switch shore power off and on at the receptacle... Ready to run again for a few days.

Like you reading this, I thought the BIM was the issue - and maybe it is. But what I have been told about this device tells me it is either switch on or it is not. I have checked dozens of times. It is switched off. That mentioned, it will occasionally click on for a brief time (less than a minute) and switch off. I'm told this is expected and would not cause the issues we have.

I removed each battery to check voltage. Fully charged, 13.56v. During discharge, it goes as low as 11.8v.

As I write this, there is a strange 5.8 amp draw, though nothing has been switched on and different since noon today when all was well and the draw was 0.5 amps. Currently, my voltage is 13.06v. The charge shows at 88% and dropping slowly. It was at 100% three hours ago.

The starter battery trickle charge is connected to the starter batteries from the Multiplus. It drops to 12.55v during failure times and returns to 13.49v for a short time, then on to 12.7v when all is working well after a restart.

I have no idea what this issue is. Is the Multiplus faulty? Is the MPPT faulty... though the solar panels are currently switched off, the MPPT is connected. Is this issue due to the BIM we bought from Battleborn?

One final item; The color monitor (Victron) will not show there are any traveling beads going from the inverter to the batteries during the failure. Likewise, while watching the Victron app while all is working correctly, if the amp draw drops below 0 amps the system shifts rapidly from "Infinite" to "nanm" to 10 days. If charging is working correctly, it jumps back to Infinite within a few minutes. However, when it fully fails, ten days drop over a few hours to only a few days or a few hours... all the while connected to shore power.

I simply can't figure out WHAT to look at or test next.

The shore power switch (permanently mounted inside a bay on the coach) is brand new. Shore power, as I have carefully monitored it, never changes at the Multiplus or the pedestal.

I've taken this apart so many times, checked every connection, and carefully reconnected according to the schematic we originally used to install this system...Which worked flawlessly for nearly two years before this happened.

I'm thinking the Multiplus is failing... But how do you test something like this???

Does anyone reading this have any ideas... If so, thanks in advance. I really am at the end of reasoning this out.

Blue Solar MPPT 75 10; new to me and causing confusion and difficulties

I hope someone can help with some difficulties and confusion I am having with my new Blue Solar! Many thanks if you can!!

Tiring of the spurious claims and poor performance of cheaper solar controllers I bought a new MPPT 75/10 about a week ago. It is required for a sailing boat I will be taking around Ireland this summer, and energy is a very important part of safe passage making.

I have looked through forums/online but cannot find information required, please can you help with some advice?

I have two batteries, (12v) to serve primarily engine and secondary VHF, navigation and domestics. The set up I have (the chinese controller removed and the Victron put in its place) is a 3 way switch on the + output from the controller : primary battery, off and secondary battery. Readouts: I have an amp metre on the output of the controller (after the 3 way switch) and a battery monitor giving voltage and amps.

Installation of the Victron: I followed the instructions in the little booklet, connecting battery first, then solar panel.

Problems: At first (few days, to see it works) I switched to secondary battery. The green soon showed it was on ‘Battery Life’ and the yellow on ‘bulk’ (terms from victron toolkit app). About 20 minutes and it showed , if I can recall, battery Life and Float (I was not sure of the meaning, the booklet is not clear and I had not yet seen the victron toolkit definitions). Next day I switched to primary and the same seemed to happen.

Problems started yesterday morning after I started the engine. Before starting the engine I turned off the controller feed to the batteries (turned 3 way switch to off) . This left the controller still connected to the PV and not connected to either battery. I ran the engine for routine engine checks for about 25 minutes and after turning off the engine I turned the 3 way switch to the secondary battery (waiting a few minutes after turning the engine off). The green soon showed it was on ‘Battery Life’ and the yellow on ‘bulk’, both blinking quite fast. From readouts it seems to have been charging and the voltage was going up. Unfortunately it kept going up and going up all day reaching 16.5 volts. It appears to me the controller no longer switches mode and, it seems is overcharging.

I waited all day for it to switch to float ( a sunny day, yesterday). I turned the switch to the primary battery and for half an hour it also did not revert to float (the primary had just had full charge from the engine.

I cannot find information on bootloader mode, I cannot find information on firmware does or if it needs updating.
