Thermal breaker on AC IN of Multiplus

Hi dear community, I know this question has been asked before, but I didn't see any answers. I want to check whether the thermal breaker has tripped on a Multiplus Compact 24/2000 at one of my clients´ installation. The charger is not taking the generator input and I have already done all the recommended generator parameters adjustments on the Multiplus via Remote Config. The problem has to be something else. The manual says to reset the thermal breaker if the charger is not working, but the front plate of the Multiplus does not have any sign of a breaker. It must therefore be on the inside I presume. I am not physically close to the installation, so I want to guide my customer on how to do it.

Thanks for any pointers.

EM24 Ethernet - lockup issue

Hi Everyone,

I am running an ESS, everything fine, BUT: My EM24 Ethernet is regularly losing the connection to the LAN. This is not a DHCP issue or such, it clearly hangs.

After disconnecting the EM24 from power (cold restart) it works again, but only for 1-2 weeks.

I would like to update the firmware and then see whether the problem goes away. This is just a way of saving time from further troubleshooting.

My problem is: Nobody will help me to get newer firmware. Victron Dealer says to contact Carlo Gavazzi. They say to contact Victron. And Victron says to contact the Dealer. Stuck in a loop.

Anyone here to help my get new firmware for the EM24 Ethernet?

My Device is a EM24-DIN.AV2.3.X.E1.X

New MultiPlus-II 2X 120V doesn't show full AC load on Victron Connect

I just installed the new Multiplus-II 12v 2x120 inverter. It's working great but the data I'm seeing in Victron Connect doesn't look right. For example, I'm on 50amp shore power and with one 15k A/C running in my RV, Victron Connect shows AC Loads at 231w. When I shut that A/C down, the load stayed at 231w. When I start up the second 15k A/C unit, Victron Connect shows 1,868w. It appears Victron Connect isn't seeing power from one of the legs on my 50 amp service. Thoughts?

Connect "ground" of load output to vehicle body? MPPT 75/15

Hi everyone!

Is there any reason I should or should not connect the ground/- pin of the load output to the body of the vehicle?

I'm having issues with my fridge (Dometic CB40 compressor, 60W) shutting down due to low voltage, so I connected the fridge as the only load to the load output of the MPPT 75/15. I used 6mm² cables, roundabout 1.5-2m length. In this first setup, ground of load output was connected directly to the ground pin of the fridge.
With that setup I was able to measure the current (up to 7A) that the fridge used. Unfortunately I still had a misterious voltage drop of 0.5V-1.0V along this connection, so the fridge would shut down due to low voltage (<10.5V).

Now I have connected the ground of the fridge to the vehicle body and the voltage seems to drop significantly less, at least the fridge doesn't swithc of any more....

But it seems that I can't measure the load current anymore?

Victron mppt 100/50 controller not charging battery

I am setting up my RV with solar power and this is my first system. The solar panel is tested and working. It is putting out 32 volts in the sun. The controller is a victron BlueSolar charge controller 100/50 mppt controller. The battery is a bigbattery 12V OWL - LifeP04 - 170 Ah - 2.176kWh.

When I connect the battery to the controller it starts flashing "bulk". However, the battery never charges. The battery is currently showing 10.99V on the front display on the battery. On the bluetooth app, it shows the same and it shows 0 volts from solar and 0 amps from solar. It only shows the battery volts and the 'current state' shows 'off'.

I believe the controller is set up correctly. If I go into settings it is set for 12V, max charge of 50 amp, charger enabled, battery set to lithium iron phosphate (LiFeP04), absorption voltage is 14.20V, float voltage is 13.50 V.

I can't get any solar charge at all. If I leave it plugged in, the battery and the charger just shut off entirely.

SmartSolar 100/15 compatibility with 125W panel
  • Hi there,

I have a basic question to ask before I buy a SmartSolar MPPT controller for my solar panel.
I have a 124.5W solar panel
Specs here:
Voc: 24.48V
Isc: 6.32A
Vmp: 20.88V
Imp: 5.97A
Ptol: +/- 3%
124,5 W
Pmax - Maximum achievable power
124,5 W
Voc - Voltage open circuit
24,48 V
Isc - Ampere short circuit
6,32 A
Vmp - Voltage maximum power
20,88 V
Imp - Ampere maximum power
5,97 A

I was was wondering if I can use a 100/15 solar controller rather than a smaller 75/10 as I will maybe add another 124.5W panel in the future.
I know a 75/10 would be proficient but I was wondering if the 100/15 will still work ok with just a 124.5W panel.
(The nominal PV power at 12v of the 100/15 controller is 220W and nominal PV power at 12v 75/10 controller is 145W.)
Does the nominal PV power have to be close to the power of the solar panel for it to work correctly.
Apologies I am new to this and would really appreciate before I buy the 100/15 controller just to make sure it will work ok and isn’t to powerful for just the 124.5W panel.
It says in the SmartSolar manual:

“PV array too small”
“If the PV array power rating is less than the solar charger nominal power rating, the solar charger cannot output more power than the connected solar array can provide”

Many thanks

BlueSolar PWM arrow fast blinking

I have a BlueSolar PWM Charge Controller – LCD - USB and a generic PWM charing the same LiFEPO battery with build in BMS (LionTron).

Very often when the sun shines, the BlueSolar 's arrow between the Solar Panel icon and Battery starts blinking fast. ( not the slow float blinking, but fast like 4x per second ). The charge current is also low (but not zero).

When I reset the PWM ( disconnect solar panel and battery / Or switch between B4 and B5 and back, so PWM reboots ) the blinking stops and the PWM charges maximum current.

I wonder why it is doing that. There is no mention about fast blinking in the manual. I asked the question to Victron through my reseller, but that did not get me an answer.

Does anybody know what this blinking means ?

Remote VE.Bus firmware updates

Hello all! On April 6th we've released Venus OS version v2.65. It adds a feature which many distributors and installers have been looking forward to for a long time: being able to remotely update the firmware of our Inverter/chargers as well as Inverters: Multis, Quattros, MultiPlusses, and so forth.

The purpose of this topic is to have one - easy to update - place to confirm the latest status, issues and improvements.

Currently, the feature is still in beta, and clearly marked as such on the VRM Portal.

Current status:

UPDATED 2021-04-19: this feature has been used a lot, and without issues. Its no longer in beta; its now a normally available feature.

General advise:
Fully study the manual (link below) from the beginning to the end before you start. The inverter/charger is the heart of a Victron Energy system, during the update AC will be switched off for a while, as such comms. might be lost as well, and so forth and forth: its a super powerful feature but does require more care than -for example- firmware updating a Solar Charger.

Where to report issues:
Preferably by posting a question here below. We're monitoring this thread.


Updates 2021-04-19:

  • Feature is no longer in beta.

Updates 2021-04-13:

  • Venus OS v2.66 released officially. Has some minor stability improvements.

Updates 2021-04-09:

  • Small bug in the VRM portal was fixed, that (sometimes) caused the final error message to not become visible. That could for example happen when uploading a settings template file without first merging the file in VE.Bus System Configurator

Updates 2021-04-07:

  • Released Venus OS v2.66~1 for testing; with some minor stability updates for Remote VE.Bus firmware updates. There is no need to use that test version to update your inverter/charger firmware.

Updates 2021-04-06:

  • Venus OS v2.65 released officially

Updates 2021-04-01:

  • A new VE.Bus System Configurator tool version was released, adding the Merge function. See FAQ Q3 in above linked manual for what that is and what its for. And also this new version has a bugfix, to fix a crash when processing the settings template from a system with Quattros.
  • Documentation and in-app texts are being updated wrt setting the charge current to zero after the update, since it works slightly different than was documented. Not the charge current is set to zero, but the charge voltages are set to the nominal battery voltage. Ie. both float and absorption are set to 12V for a 12V system, to 24V for a 24V system and 48V for a 48V system. We’re doing this instead of setting the current since this works better. Also, in a DVCC system, its good to know that these settings will be overruled by the managed battery; and thus the system will be charging, even though the settings havent been restored yet. Which is fine: there is no risk of battery being overcharged when the battery BMS is in charge via DVCC.
  • The mechanism works stable. No known issue.
  • The release of Venus OS v2.65, the version adding this new firmware update feature, has been delayed to after the Easter weekend.

Model selection needed - Also Input Voltage 120V versus 230V. Help please.

In my RV, I currently have 12V battery and 120V "shorepower". My generator is Onan 10KV "Quiet Diesel", configured to output 120V.
The inverter for this system is junk. It does not "power share" and it's constantly breaking down.
I am also considering a new airconditioning system that requires 240V (US Standard).

So, there are a couple of background situations.
1) I can easily reconfigure my generator to 240V output (240V on two 120V output "legs"). My shore power cord and transfer switch are already configured to handle 240V but the actual feed into my current inverter-charger is single-leg 120V.
2) I will need to install new 240V wiring to the new airconditioning system from a new 240/230V interter charger. No problem.
3) I have approx. 700 Amp/hr of battery capacity (AGM, 12V). This battery bank would be easily reconfigured to 24V by recabling pairs in series. Again, no problem.

My technical issue : Frequently, I find that I'm limited to 120V input on the road. This can be 15Amp/120v (ordinary household current outlet) or 30Amp/120V ("TT" RV connector). I have 240V service at my home shop/garage and many RV parks have 240V outlets, but not all.
So, a basic question, Does Victron make an RV-suitable unit with about 4KW, 240V output that will accept either 120V or 240V shorepower/generator input? If so, which Victron model will do this?

Assuming the answer is no, what's the best arrangement?
Using a 120V - 240V transformer with a 240V inverter charger (with 240V input from the generator) and running a normal 240V house system from there? With load-balanced split legs for house 120V circuits and 240V to the airconditioning system.
Or use a 120V inverter charger, continue to use 120V from the shore power and generator, with a 120V - 240V transformer fed from the inverter-charger output to power the airconditioner system?
(All the above considers the battery bank configured for 24V). Which Victron model inverter would be best?

Thank you. I look forward to converting to Victron for my RV power needs.

Virtual switch / alarm output not working.

I have a really old victron multiplus compact 2000. I have tried to get the alarm output to drive a relay that will start a generator. I have had no luck in ever getting the alarm output to trigger the relay. I know the most likely option is that I have done something erroneous, but I can't help thinking the output is not working. I have programmed a lot of different options to debug the issue using VEConfig. To the very least I would expect checking the "invert VS" button would make the relay switch, but no.

What if the previous owner shorted the output, would that damage it? Any way I can see if has been shorted? The connector does not sit straight, seems like someone has used significant force to fasten the wires. What is the likelihood off damage? If damage is likely, have anyone tried repairing it? I am well above average on electronics and soldering, but I still need to know what to do.

I have connected the right alarm terminal to battery GND. The right terminal is connected to on terminal on the solenoid on the relay. The second terminal on the solenoid is connected to 12V battery. The intent is that the alarm output will allow current to flow in the relay solenoid and switch the relay on. If I short the wires going into the two alarm terminals, the relay switches.

Any ideas? Please do not ask med to deliver it to a dealer. It is installed in a cabin in the mountains and the unit is really old. The motivation to dissemble it, transport it back and forth, etc, is really low. If I cannot get it to work myself, then the unit will never start the generator.

Anyone had similar issues?
