Remote VE.Bus firmware updates

Introduction:
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 2021-04-09: this feature has been used a lot, and no issues have been found so far; if this continuous like this, we'll remove the BETA sign next week - its working really well.


General advise:
welcome to use the feature, but be prepared to have to self merge the configuration (see FAQ in the manual) and in more unlucky cases to have to travel onsite.

And (of course) fully study the manual 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 cool 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.


Manual:
https://www.victronenergy.com/live/venus-os:remote_ve.bus_firmware_updates


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.

updated above text, now that v2.65 has been officially released.

Thank you! Has the latest version of the Large OS also been updated to add this feature set?

Yes; see Venus OS Large latest release notes to see what version exactly. All basics are in; some error handling such as for example precisely telling a user what else he needs to do in case he uploads a file without merging it first is missing. There will be a new Venus OS Large version soon. Probably a week or two from now.


ie after the v2.66 that I expect to come with some more VE.bus fw update error handling is finished.

Sounds great. Thank you!

Could you please point me to the location for the Venus OS Large latest release notes? All I can seem to locate is the DropBox folder with the images.

Hi, yes see in the manual: https://www.victronenergy.com/live/venus-os:large#status_and_where_this_development_is_going.


It links to everything, including the release notes. I made it a bit more clear just now.

I successfully updated my system (Multiplus-II 48/3000/35-32), from version 478 to 481, using the Remote VE.Bus firmware update.

My only concern is that, during the update process, the mains charger was enabled until the "merged settings" were uploaded. The total charge current into my battery was therefore very high (70A) since my MPPT 150/70 was also charging the battery at 30A.

I had expected the mains charger function in the Multiplus to be disabled - as per the online documentation - see section 3.2 Note 4 below.

"After the firmware update is completed, the settings will have been reset to their defaults. Also, to prevent overcharging, the charge current is set to zero amps, and then the inverter is switched on again."

Any chance also older CCGX can have this feature or is it "impossible by hardware"?
Our (yes, old) test system fulfills all requirements except

If there is no other way, we'll replace the CCGX with a Cerbo.

Hi, a CCGX not meeting the stated minimum requirements will never get this feature. Not soon and also not later.

I've got a Venus GX running V2.63. when I go into Online Updates, the bottom line is "Update available Press to update to v2.65". When I press this, it changes to "Installing V2.65"

After a few minutes, it goes back to saying "Press to update to v2.65".

when I press it again, it says "Error during installation", then goes back to "Installing V2.65"


Any ideas what's going on here? Internet connection is stable as I can see real-time info from the device in my VRM.


Many thanks

Ceri

Does this apply for parallel and 3-phase systems aswell?

Did you even read the manual? This is clarified at the beginning ;)

Brilliant! Can someone get this feature on a too old CCGX by using an MK3-USB?

Hi Porcini, probably, yes.

That's interesting..

Hey @Porcini if you do get to test it using:

Multi/Quattro --->MK3-USB --->CCGX (Old version)--->Pc (VRM)

..and it works, please report back! I might have to swap out my MK2-USB and use a MK3-USB in the CCGX USB port for VE.Bus communication.

Thanks Al

The release version shows up af 2.65~9 in my Cerbo GX, when I check for updates (I am on "Latest release" channel).

Should be named 2.65 (without ~9).
