Using ESS off grid without a generator but with Solar PV

Hi All,

I've seen the ESS manual where it says not to use offgrid/intentional islanding but not sure I fully understand why. My use case is :

  • ESS system with Quattro (sized to handle all house loads), batteries sized to run house loads for >24 hours.
  • On a cheap rate tariff (6 hours overnight) - plenty of time to fully charge batteries - uses ESS scheduled charging.
  • System also has Solar PV and I have an automation to estimate to what SoC batteries need to be charged overnight so that they shouldn't reach 100% during the following day. Uses ESS settings to control overnight charging level.
  • No generator
  • I want to run on-grid for the scheduled charge window, then off-grid during the day until the next scheduled charging window. Thus I can guarantee that when the inverter is running it is not connected to the grid (and absolutely guarantee that there is zero feed-in to the Grid).

I could just physically cut the AC1 IN via the isolator but I don't want to get up at silly-o-clock! From what I read elsewhere this might be possible using a flag and generator options but comments mostly seem to say don't since it it's not a supported combination with ESS.

Appreciate any comments/thoughts?

Octopus Agile API Support by Victron For Controlling Charging Off Peak Times

Thank you so much for the very informative webinar on 23/11/22.

Octopus Energy in the UK is disrupting the energy industry for good and their Kraken platform is in many countries bought by suppliers and growing.

Will Victron please look at integration with Octopus Kraken API to allow us to auto set charging times when energy prices are low and export when high?

“Works with Octopus” is a standard attained by many ESS systems and it would be great if Victron would look at putting this on their roadmap.

NodeRed and some technical challenges aren’t for all of us and I believe it would help in adoption of Victron into many domestic installations where people just aren’t getting the quality and support from certain other brands.

Standards to help home storage and EV take-up are so very crucial to environmental gains and the rapid change needed to combat climate change.

Many thanks for your great work. New Solar ESS Victron User in the UK, Installed by Callidus, another great cutting edge supplier and supporter of Victron.

connexion et parmétrage sonde T° sur cerboGX


après avoir connecté 4 sondes T°(autoconstruites LM335Z) sur les entrées analogiques d'un cerboGX, je n'arrive pas à les nommer , personnaliser et calibrer dans la liste d'appareil, meme en rentrant dans le sous menu configuration ou appareil (qui ne laisse que 3 choix tres restrictifs batterie, generic, refrigrerateur) et ce malgré ce qui est annoncé dans le manuel cerboGX :

Le paramètre de la température peut être configuré comme Batterie, Réfrigérateur ou Général. Vous pouvez également déterminer un nom personnalisé dans le menu de l'appareil.Vous pouvez régler le décalage et l'échelle de température.

pour info la version micro logiciel est v2.56

merci de votre attention.

Température Pylontech

Bonjour Tout le monde,

Par ces fortes chaleurs, notre matériel est mis à rudes épreuves...

Même si la plage de fonctionnement de nos batteries Pylontech va jusqu'à 60° et que 25° semble le top, quelle est la valeur "raisonnable" avant d'acheter un climatiseur pour nos locaux techniques?

ET112 ESS Distribution Board Installation

I am confused as to how to install my ET112 meter. I have a zigbee to send the meter info back to the Cerbo GX located in the garage.

(my setup is a DC coupled PV ESS install on a house in the UK)

Question 1: how do I wire in the meter? I need a simple-to-follow picture/diagram, my presumption is that is goes to the left of the main breaker switch and the live goes in position 1and out of position 2 with power from the Neural at the bottom?

Question 2: should I be running AC in to the inverter? At the moment I don't think I have setup the system to charge the batteries via any other means than via the MPPT. So should I run an AC in and also an AC out on the same cable that feeds the garage circuit?

Question3: I have 2 sockets running off AC out 2 - I wanted to have these as 'always on' even if there was a power cut but I can't see where you enable this output (the system isn't get wired into the house circuit which I was going to use AC out 1 for).

Multiplus II 48/10000 and VE transfer switch instead of Quattro

Given that the Quattro II 48/10000 isn't yet available and probably won't be by the time I need it (and I don't want to use the old Quattro model), can I get exactly the same functionality (for switching between generator and shoreline) using a MP II and the VE automatic transfer switch?

As well as changeover, is it possible to use the ATS auxiliary relay output as an input to the Cerbo/MP II to tell it to automatically change the input AC current limit from 39A (generator) to 16A (shoreline)?

MPPT Too long in Absorption

I have the old style Blue Solar MPPT , the one with a small screen and 4 buttons on the front . I cant understand the Absorption , Manufacturer says absorption time should be 5 hours so to achieve this I set the MPPT for 15 hours . Voltage prior to it charging is between 24.4 and 25.7 every mornings so it should stay ion absorption for 1/3 of 15 hours which would be 5 hours , 300 mins . Sometimes it stays in absorption for exactly 300 mins to the minutes other times its longer , yesterday 446 mins . I know if the tail current gets down to 2 amps it will end sooner but no explanation foe it going on for longer other than if a heavy load is used which there never is , i have compared the days that its correct at 300 mins and the days its longer and i cant see anything to explain the additional time . I only have a Solar Array , no other input . Is there anything i can do .

Victron Smart Solar MPPT 150-85 and MultiplusCompact 3000 /12V 120A

I have 12V traction batterie bank consisting of 6 ETERNITY 8PzS-ET 1000-LM 2V batteries in series.

For my 12V battery bank ETERNITY informs the following values: the absorption voltage is 14,7V, the floating voltage is 13,5V and the equalization voltage is 15,3V. Have I understood right that with "Victron Connect app " with PC I can put these right values into MultiplusCompact inverter charger and SmartSolar MPPT 150-85 charging controller?

If I will execute the equalization in one day with MultiplusCompact, shall I only put the item "use equalization" ON in the APP?

Can GX generator start/stop feature control AC in of Quattro?

Hello all,

For a setup on a yacht, I want to control the AC in 2 of the Quattro so that during the sunny hours of the day, the shore power does not charge the Quattro. The result is that during the day only my solar panels charge the batteries.

I enabled in the Venus GX the feature generator start/stop, in such a way that the generator starts at 18.00 and stops at 08.00 hrs. I then set AC in 2 in the GX to generator. I am assuming this then controls relay 1 of the GX and switches it on and off based upon the indicated hours.

I then wired relay 1 of the GX to the auxilary relay of the Quattro.

With VE-configure, I added the following assistant to the Quattro:


Will this work? Will the AC in 2 be ignored from 08.00 till 18.00 hrs?

Inverter state control doesn’t seem work for “power on” mode from vrm

Multiplus 3K connected to venus os 2.92 on Raspberry Pi


The image above shows the 4 ways that I should be able to control inverter state. If the inverter is on, i can set to the other 3 states (off, charge, invert only). However, if inverter is off, the only way I can turn it on is using the victron connect app (bottom left of image). With any of the other 3 interfaces, the buttons indicate the unit is on after pressing on and then refreshing displays but the inverter remains in the off state.

Michael Ziegler asked a potentially related question on Mar 16 2022 at 8:52 PM under the topic: “Control your devices in VRM showing incorrect inverter state” and i attempted to ask if this had been resolved but there was no response.

I have tried reinstalling venus OS and that did not help. The general settings for remote access/remote control are set to True. I would have to believe this isn’t an issue on a true cerboGX and touch control otherwise it would be a major issue. My reason for implementing venus was to allow my wife (not overly technically inclined) easy control of the inverter. Without this functionality I will just have to depend on Victron connect app as I have for the last year.

Victron VRM Presentation: VRM Push Notifications on iPhone - Not Working

@mvader (Victron Energy) I really enjoyed the presentation yesterday on what the VRM enhancements are and what it can do. So many great new features. I am excited about the push notifications so I went through the steps you outlined in the presentation, but upon downloading the Victron VRM app, it did not ask me about push notifications at all. And in the VRM, I do not see any way to add push notifications to my phone at all. I'm running the new iPhone 14 Pro Max. Just downloaded it, went through the steps. Isn't working for me. The new Preferences selection inside the app is not there. There does not seem to be an update available in the App Store.

Please can you clarify if the app has not yet had this feature enabled since the presentation was only yesterday?

I'm also not seeing in the app the ability to add those custom widgets. I'm only seeing the widgets from my Advanced page, but not in the same way as was shown in the presentation.

Thanks for your contribution to the community!
