Venus OS v3.10~32 available for testing

UPDATE 2023-09-01: This thread is now closed, see here instead: https://community.victronenergy.com/questions/228708/venus-os-v31032.html

Good morning!

Per just now, a new pre-release of v3.10 is available, v3.10~22.

Detailed change log below, but first more details and screenshots of the v3.10 highlights:

Solar and wind priority for boats, vans, and other systems with a shore power connection.
New ESS "Self consumption from battery" setting
New Marine MFD HTML5 App
Generator improvements: CoMap integration, a resettable service interval counter and autostart-disabled alarm.

Here are the details for those highlights:

1. Solar and wind priority for boats & vans

The new Solar & wind priority gets to work when plugged into shore. It then ensures that solar & wind power are used to charge the battery, while the shore power is only used to prevent the battery from becoming too deeply discharged.

Its a new installer setting in our range of inverter/chargers, and a new charger mode: Sustain. Here is a screenshot, also note the graphics in the battery icon:

For further details, see the Solar and wind priority draft manual.

2. New ESS "Self consumption from battery" setting

This setting allows for ESS to only use battery power for essential loads. This is relevant for ESS systems with (a) a grid meter, (b) quite significant non-essential loads, (c) Feed-in disabled. The setting allows battery banks to be sized to get critical loads through the night, without the battery being discharged into the non-essential loads.

Screenshots of the new setting, first one shows the default, all system loads:

And here the other, new, option: only critical loads:

3. Completely renewed Marine MFD / HTML5 App

And here a more extended system, with more tanks, and more energy sources:

Note that above two screenshots are taken from the design files, it might differ a bit from actual implemenation.

These are screenshots taken from the new implementation, but there I'm not able to now have them embedded in actual look on a marine MFD like above:

And white mode:

And for comparison, here is a screenshot of the old version:

4. Next, there are three more improvements related to Generators

adds support for ComAp generator controllers. Integration via ethernet/ModbusTCP; using the ComAP CM Ethernet module.
adds resettable down counting service interval for generators
add an alarm when generator is not in autostart mode for more than 10 minutes. This is to help prevent systems shutting down because during service someone had to enable manual mode; and then forgot to put it back to auto mode. The alarm is optional and can be enabled from generator start/stop settings.

Here is a screenshot on how to enable this on a CoMap generator controller.

(click for large)

The data that is being read from the controller is:

AC Power, Voltage, Current and Frequency and Energy
Engine speed, coolant temperature, Oil Pressure, Load percentage, Operating hours and starter battery voltage.
Status (init, stopped, error, preheat, and so forth)
Auto-start status (off, manual, auto, test)

We'll later publish a list of ModbusTCP registers.

For the developers amongst you, the driver that reads that data is public; commit here. And we'll be looking to integrate other popular generator controllers as well. In case anyone can help; or has a generator with for example DSE or Deif, then please post some details (which model / modules for example) and perhaps it can be of help. A large part of the work is figuring out which model is the popular one, which is the right protocol to use, and so forth. As you can see in that commit, the actual integration is not that much code.

Then, onto the other two new features, service interval and autostart-is-off-alarm:

Here is how the new service interval is visible in the menu:

Here is how to configure and reset the new service interval:

Here is how it looks when the interval is exceeded:

Still open for this is to show this, for a whole fleet, on VRM.

The new autostart alarm setting:

Short explanation when enabling it:

Introduction to Venus OS beta testing & how to join/install

In case you don't know what this message is about, please start with reading this link, which explains the Venus OS beta program. Venus OS is the software running on all our GX devices, such as the Cerbo GX.

How to post an issue?

By posting an answer below. Do please keep all findings organised: one answer issue per issue. So first check the existing threads if your issue has already been seen. And if it does, add a comment saying "me too". And preferably some more details. And in case its not listed yet, add a new Answer.

Note that Answers and Comments are two different things on this portal.

Lastly, before posting issues, preferably first revert to the latest official release (v2.93), to double check if the issue you're seeing was present there as well. Regressions require a different treatment than other issues and bugs.

And include information about the results/differences in behaviour in your report.

Running, Node-RED, Kevin’s GuiMods or other add-ons?

Then please at least say so in your bug report.

GuiMods and other 3rd party add-ons: don’t report your gui issues here. Do it elsewhere instead.

Changes made by us often cause a compatibility issue with the GuiMods; and these betas report pages are for official firmware only.

Changes v3.10~31 and v3.10~32

ModbusTCP:

Make the ESS max discharge current a signed integer
- This is so that -1 can be set, which is needed to disable the limit
Add MppOperationMode registers Individual Trackers on RS devices
- adds registers 3731 t/m 3734 for MPPT RS
- adds registers 3169 t/m 3172 for Inverter RS
- adds registers 4605 t/m 4608 for Multi RS
Add registers for reading- and resetting generator service interval: Registers 3510 (32-bit) and 3512

Other:

Dynamic ESS beta: Correct a situation in DynamicESS where it locked out charging/buying under the DESS MinSoc.
Further improve vrmlogger stability in case of storage issues, to enhance remote diagnostic options.

Venus OS Large:

node-red-contrib-victron v1.5.0
- Adds a custom input and output node. This is an extremely powerful new tool in the Node-RED tool box, which I’m sure many will enjoy. Here is the summary, also in the documentation:
- The input node allow to read from and the output node allows to write to all found dbus services and paths. This obviously comes with a risk, as not all services and paths are supposed to be written to. So only use the custom output node if you have read the documentation and know what you are doing. Also note that used services and paths might change, so there is no guarantee that a node will remain functional after a Venus firmware update.
- So, enjoy, but be careful!

Changes v3.10~28, 29 and ~30

Fix connection issue with ABB meters
Further developments on the new MFD/HTML5 app.
- Add 'time to go', voltage and amps to batteries
- Make the Batteries Overview component bigger
- Show tanks with missing remaining and total capacity
- Add support for all tank measurement units
- UI improvements: change icons and make them bigger, increase text size and line height based on screen size, decrease box padding on smaller screens.
- Fix battery names not showing on Garmin in certain splits
- Fix missing spacing on Furuno due to unsupported CSS properties
- General layout and spacing improvements
- Change the breakpoints for box components.
- Add padding for phases.
- Remove hidden overflowed text in Boxes.
Fix issue causing GX Touch 50 showing the wrong resolution in case the GX device can't read the resolution data from the display. Note that this only fixes it for the GX Touch 50, not GX touch 70. What it does now is use GX touch 50 resolution by default, rather than some much larger resolution. In case you have such issue, remove/re-insert the HDMI plug a few times, that is known to solve it. And otherwise, RMA.
Improve vrmlogger fallback in case storage is corrupt.
DVCC / Managed batteries: add per module diagnostics, so that technicians and support personall can more easily identify, especially remotely, which battery module has an issue. There are currently no battery makers yet that support this.
Improvements for EM300 and EM500 meters in case using them for single phase systems, with their main measurement on L1, + piggybacking an inverter on L2.

Changes v3.10~26 and ~27

Developer only: changes to mqtt, introducing heartbeat topic. Further details will be added to the mqtt issue, and see meta-victronenergy as well as dbus-flashmq commitlog

Changes v3.10~24 and ~25

Internal changes

Changes v3.10~23

Fix bug where sometimes, consumption from a Multi-RS is not correctly logged to VRM
Add support for upcoming Victron Energy Meter (VM-3P75CT)
Few Modbus-TCP additions:
- Add 32-bit registers for ESS/Hub4 setpoints. This is for systems larger than 32kW, using external control. The existing registers were only 16-bit.
- Add registers for PreferRenewableEnergy and Generator selection. This allows using modbus-tcp to force a charge cycle on a system with Prefer Renewable Energy enabled. Indicating that a generator is running, or reading the state of generator selection has been added as well.

Venus OS Large:

Update SignalK server from signalk-server v1.46.2 to v1.46.3
Update signalk-venus-plugin from v1.29 to v1.30.2

Changes v3.10~22

Finish work for the new "Solar and wind priority" feature, for boats, vans, campers and other systesm with a shore-power connection. More details on that feature here.
Add new ESS setting that allows for ESS to only use battery power for essential loads. This is relevant for ESS systems with (a) a grid meter, (b) quite significant non-essential loads, (c) Feed-in disabled. The setting allows battery banks to be sized to get critical loads through the night, without the battery being discharged into the non-essential loads. Thank you @Warwick Bruce Chapman for your help in that!
Prepare for Dynamic ESS in VRM, the next step that is coming after our Node-RED implementation of Dynamic ESS.

Changes v3.10~21

fix bug in digital inputs, related to recent generator changes.

Venus OS large:

signalk-server: fix issue that caused the app overview page on Navico MFDs be slowish every 30 orso seconds.

Changes v3.10~18 -> v3.10~20

Stability improvements related to recent digital inputs change icm generator/transferswitch status
Internal changes

Changes v3.10~17 -> v3.10~18

Various improvements to the new HTML5 Marine MFD App:

Update the keep-alive mechanism to include missing data
Add Amps to battery overview component
Change theme settings menu UI&UX
Fix Remote Console control buttons
Fix "Request denied for security" issue

Changes v3.10~16 -> v3.10~17

Add new solar and wind priority feature for boats, motorhomes, trailers, service vans and other systems that (a) hook up to shore power regularly, (b) have solar or wind or other renewables, and (c) have a Multi or Quattro. More on this asap.
Add “stopping” state to the generator. Its now first running, then, if enabled, cooling down as long as configured in GX, then 15 seconds stopping to accomodate generators that take a while to stop, and only after those seconds the inverter/charger will reconnect to mains; if available. Fixes issues with generators that take a while to stop in combination with the recently added cooling down option.
Digital inputs: when configured to measure generator- (or perhaps more precise, external transfer switch- ) state, pass that info over to the Multi. Used for new solar in wind priority option when used on systems with shore, generator, external transferswitch and Multi; rather than Quattro.

Changes v3.10~12 -> v3.10~16

Fix issue in CAN-Bus timing for Ekranos, as well as RaspberryPis icm FD HaTs based on the MCP2518FD chipset.
Add support for Quattro-II 12/3000/120-2x50 2x120V
Add support for 12V Pylon batteries

Venus OS Large:

node-red-contrib-victron v1.4.33
- When 'only changes' is checked make sure the initial is reported.
- Updated documentation.
- Support for reading from and writing to ESS schedules.
- New examples: generator, load shedding and sum power inputs.
- Don't show rounding on output node.
- Minor fixes in the services file.

Changes v3.10~11 -> v3.10~12

Marine MFD HTML5 App: improve load speed on the MFD as well as reduce CPU load on the GX device induced by opening that app, by changing the underlying data connection. Previously this used Mosquitto MQTT broker (and a python script), now this uses a new broker called FlashMQ (and a Cpp plugin). Its mainly an (enormous) performance improvement. For comparison, on a system having 1500 data points, in the old solution this took 3 seconds and 2900 TCP packets to transmit. In the new solution this is down to 10ms and 179 TCP packets. Tech details in next bullet point:
Local MQTT websockets connection: use FlashMQ + dbus-flashmq instead of Mosquitto + dbus-mqtt, see above for details. Details:
- FlashMQ and Mosquitto are now running side by side.
- Local websocket requests, ie Marine HTML5 app, are served by FlashMQ + dbus-flashmq. All other requests, ie local MQTT requests as well as all that comes from VRM, still goes over Mosquitto + dbus-mqtt + mqtt-rpc. Changing that is the next stel.
- Further details in this github issue. Though please don't clutter that issue with all sorts of requests, doing so triggers mails to many developers, and I'd like to keep focus / efficiency.

Changes v3.10~9 -> v3.10~11

vrm real time mode / mqtt: fix bug where a network issue could cause the data connection to VRM be lost, and real time display to not work properly.
Modbus-TCP: fix Multi/Quattro state register reporting "External control", while it should not.
Renewed HTML5/MFD app:
- The back button has been moved to the footer making it reachable on Simrad devices.
- The pagination buttons are now in the center of the footer.
- Sensors in the Environment tab are now identifiable by the custom name of the sensor or device.
- Implement data unavailable state for tanks.
- Increase button touch area.
- Fix tanks not being displayed correctly.
- Fix Inverter control.
- More contrast on the settings page.
GUI
- Update translations
- Add support for new Quattro-II 2x120V model
Various internal changes to prepare for the full featured version of Dynamic ESS, that works with Solar irradiance forecasts and dynamic tariffs as we have in the Netherlands. Proof of concept here.
raspberrypi: support the RS485 on the Waveshare RS485 CAN HAT (B). Thank you herrfrei!

Changes v3.10~8 -> v3.10~9

Add support for Pylontech Pelio-L model, including auto detect and configuration. (DVCC on, SVS off)
Fix bug in remote firmware updates for systems of three units and more. Bug was introduced earlier in v3.10 beta series.
Complete ModbusTCP mapping list for unit ids above 255. From now on it will not longer be required to get into difficulties when having a VE.Direct-connected or other type of device that has a VRM Instance above 255.

Changes v3.10~7 -> v3.10~8

GUI: Fix energy meter showing only a blank page. This was missing in ~7.

Changes v3.10~2 -> v3.10~7

General:

Allow temperature sensors to measure down to -40 °C, was -20 °C.

Under water / developer / Venus OS Large:

Add wifi for raspberrypi zero2w and rpi4. Thank you @Bathnm for your work on this!
Remote VE.Bus firmware updates: changes to accommodate new models.
NodeJS: update from v14.17.6 to v18.16.0. This brings us on the latest version of an LTS branch: all good for some time to come. Thank you @Bathnm for your work on this!
Various updates to system packages, including security issues.
MQTT: pre-install, but not activate, a new broker: FlashMQ. We're replacing Mosquitto, plus our dbus-mqtt service, by FlashMQ + dbus-flashmq. Further details are here.

Changes v3.00 -> v3.10~2

New html5/Marine MFD app. First time we’re beta testing this new UI. Its a complete redesign (totally new look including larger font size, adds tank levels, adds temperature and humidity, and more improvements) looking forward to hear what everyone thinks of it. Some things still need fixing:
- Temperature, Humidity and Pressure sensors are not shown using their name.
- On Simrad, the tank levels are not all aligned on the left side
- On smaller split views, the section title, graphs and values are very squeezed together
- On Raymarine the component in the top left overlaps the home button
- Scroll behavior is different when component is horizontally aligned (pagination vs scroll to see more tanks)
- Locking controls not clickable in horizontal split
- When more than 2 batteries, battery component overflows. Not sure if this is a bug or a feature
- Changing the units to Fahrenheit in remote console doesn’t change them in html5
Support for ComAp generator controller, details above
Adds resettable down counting service interval for generators
Add option to get an alarm when generator is not in autostart mode for more than 10 minutes
Fix VRM Portal connection for a small batch of EasySolar-II GXes (double VRM Portal ID)
Add Inverter and Multi RS DC Power path; fixes an issue with the EV Charger.

Developers:

Change how venus-data files are handled:
- pass extraction result as argument to the post-hook ('success' or 'extraction-failed'), so it can cleanup in case of failure and/or stop continuing.
- look for venus-data-*.suffix as well, so the file name can be changed to describe what it does. Multiple files can be present now.

From Local, unfound address message.

From VRM Portal: Receive the following messages: first requests a security certificate, then:

Error: remote installation does not seem to have a running Signal K service.

Reverted to V3.10~22 and Signal K server came back online.

@mvader (Victron Energy) , thanks for the response.

Following your post, attempted again to upgrade to ~23. Note that I am upgrading from a fully functional/accessible SignalK server on version ~22. Still receiving the following on local access and VRM. This time I captured a screen shot of the security certificate request mentioned in the original post. Per the original post, the local certificates do not resolve this issue.

Above from VRM Portal

This from local.

The above accessed from a fully updated Windows 11 computer. Below is access from an android phone/tablet via VRM:

Appreciate further followup. Advise if I can provide further. For now reverting back to ~22 again.

hi @Kelzamedic , what is the url of your installation on VRM, and is it ok if I login remotely to see if I can find anything?

You'll then have to update again to the non-working version ofcourse.

Note that any reports about accessing SignalK via VRM are not necessary, lets focus on getting it to work locally first.

kelzamedic mvader (Victron Energy) ♦♦ commented · Sep 01, 2023 at 03:29 PM

Access is granted, pm'd with URL previously. System is currently v3.10-32 awaiting your login. Please advise when you have completed so that I can revert back to 3.10-22 as the current version continues not to work and I routinely use the Signal K server.

It should be noted that the Signal K server is completely offline, not reporting any data to the WIFI system and/or internet, and is not running in the background and inaccessible.

@mvader (Victron Energy) Same error messages as @Kelzamedic

When connecting via SSH the service is listed as running but with very short up time, 1-10 seconds, seems it is constantly restarting? Web and VRM is not working. Node Red seems to have the same issues but that might have been since earlier FW.

I have not tried reverting to V3.10-22

Thanks for the great work on the fantastic Victron products.

Hey @MasterJR , can you take a look at the logs?

should be something like:

then you'd see all of them, timestamped, and can scroll through them.

I've noticed something similar (v3.10~23):

the marine app overview shows my 5 tanks: LP R, LP L (mopeka sensors); Waste, Black, Fresh (SeeLevel N2K sensors).

When clicking on the Tanks icon, that page only shows 4 tanks (Fresh is missing).

I still have this same issue as well - Blackwater tank shows up in the overview screen, but not in the tanks screen. That particular sensor is a Garmin GFL-10. My other four tanks show up just fine (one other is also a Garmin and the others come from my arduino).

Hi @andre, does the KUS NMEA 2000 fuel tank level sender show up on the device list of the GX and VRM? If that is not the case, then the HTML5 app won't show it either.

There are two flow pages. The the basic flow overview (not shown here) is used when the system AC connections are simple. The PV Inverter tile appears lower right above the PV Charger tile if present. The PV Inverter tile in this flow page DOES include the leg powers. This is also true for the "tile overview" shown above.

The "grid parallel" flow overview has three optional PV Inverter tile locations and none of them include leg powers. I'd agree this is an omission and the grid parallel PV Inverter tiles should include leg powers.

However, this is NOT new to v3.10 beta so should probably be moved to a new question.

Hello, I try to understand the advantage of the new funktion "self consumption from battery" but I can't find it at the moment.

For my understanding for overall balance it should be the same if the System supports all loads for 5h (in my example) until minSoC and than supply all loads from grid as supporting only the critical loads for 10h while the normal loads are powered from grid all night. In both cases 10kWh are bought from grid and battery SoC is at 50% in the morning. I would think that the case "all loads" may be even more efficient because inverter runs on higher load in a more efficient working point.

Can someone explain this?

Prioritizing solar and wind power over grid is a way to minimize energy cost IF you have enough renewable energy to support your loads and don't need to pull energy from the grid most of the time.

The current solution only prioritizes renewable energy for DC loads so if your AC loads are significant then this won't help much either.

ESS is a better solution overall since it allows peak shaving and managing power for all loads (AC or DC).

ESS can't be used for mobile installations however so this is a step in the right direction for RVs and boats.

I just installed the new firmware so I have to see overnight what is does. But in my opinion it helps avoiding to empty the battery when heavy loads like EV Chargers, heatpumps etc. are on the non-essential loads side of your ESS. If you have only a 10kWh battery and your EV charger is running at 11kW you can calculate how long it takes when you are left with an empty battery. So with this setting (I assume) ESS will not compensate the non-essential energy at the grid setpoint and will take that energy from the grid.

with regards to no longer needing the Ext. Transferswitch mod by @Kevin Windrem :

What happened during our development of solar & wind priority development is that, you could say as a bonus, the GX as well as the Multi can now know status of an external transferswitch. And the GX will also use that to either show "Shore" or Generator" in the AC input box.

@Kevin Windrem can you comment on this further?

Note that there is a bug in the current betas, causing that box to show Generator always when having a Quattro and shore wired to AC in 1.

Kevin Windrem mvader (Victron Energy) ♦♦ commented · Aug 25, 2023 at 02:54 PM

Victron's recent work is a partial solution for an external transfer switch. It uses the "generator is running" digital input to change the names of the AC input tile and to override renewable energy priority. It does not change parameters like the AC input current limit or the stop on AC present parameters. There is also a potential conflict with using "generator is running" to also indicate AC input source. If the generator is running but NOT feeding the Multi/Quattro then the GX device will improperly switch the AC input to generator. It is possible to filter the generator running state externally by including the state of the external transfer switch to minimize the conflict.

What ExtTransferSwitch adds is a second digital input to reflect the state of the external transfer switch to the GX device that is independent to the generator running digital input.

ExtTransferSwitch also allows different AC input current limits to be set for shore/grid and generator, Separate settings for stop on AC input present are also provided. The latter allows the GX device to override automatic generator run if shore/grid power is present.

As a side note, GuiMods uses the generator is running digital input to qualify time accumulation. This allows the total, daily and service time accumulation to be more accurate. It also synchronizes the GX manual run with the generator is running digital input. Together this allows external generator run control to integrate with the GX device. For example, if the generator is started by local control, the GX device manual run state will update to indicate this, and time accumulates. If the generator is stopped by local control, the GX device will deactivate manual run, but more importantly, will stop time accumulation even if an automatic run condition is still telling the generator to run. With these enhancements, it is essential that generator is running and transfer switch state digital inputs remain separate.

Hey both, after some discussing internally:

Having (limited) support for external transferswitches slipped in with the work on the solar and wind priority project.

And already there is a bug in there, when having a Quattro with shore wired to AC in 1.

I’ve decided to remove the showing of generator/shore in the UI depending on the digital input. I’m sorry, but we don’t have the resources now to get all into this.

Plus: there already is a nice solution by Kevin.

Solar and wind priority will still work as documented, since its completely independent from the GX device. On a Quattro, AC in 1 is, by that feature, assumed to be the generator, and thus charges at full power. And AC in 2 is for shore.

Hi @mvader (Victron Energy) and @Kevin Windrem

Thanks for the great responses.

I am going to get stuck into some testing over the next few days.

As I'm using 2x multis the Quattro issue wasn't a worry.

I am using dual digital inputs though I am cheating a little as the are Actully triggered at the same time, somthing I might have to investigate altering though hasn't been an issue, the contactor is Actully controlled via a timer relay so when it switches in the Multi goes into ac ignore now for the warm up period (which is what the timer was for originally)

The GUI mods solutions been working great for me regarding the system information, tbh I have quite a lot turned off but the generator overview and the addition of alternator info really are the two things I feel should be core to Venus OS, though I know the new GUI is in the pipeline!

I'm exited to get stuck in to testing the solar priority feature, when the boats alongside we often have periods where we miss out on the benifits of our panels.

One thought I had as I was typing this, and I'm sure it's possible to achieve in node red but, linking to the forcast solar and consumption algorithms in VRM, could the Multi be switch to ac ignore when the vessels statiinary and the contactor is on shorepower? Then we would also take care of the AC loads in an intelligent way.

The assistant in the Multi is quite clunky for this and I have experimented a bit and at the moment I just use relay 2 and vrm to remotely achive it.

Thanks @mvader (Victron Energy) for the update.

I'll make sure GuiMods / ExtTransferSwitch functions properly for v3.10, including with a Quattro. I'm currently using the changes made to show Generator in the AC Input tile based on the override but will back that out also.

I think we have a very workable solution with the Victron changes for v3.10 and my mods.

One thing: Some will want the grid to override generator. I think that will work if the stop generator when AC 2 available works on the Quattro. That would need the AC 2 input to detect power when the Quattro is using the AC 1 input. Does that happen? If so, I'll make sure my changes to startstop.py handles this case if it does not already.

I selected the option to power only critical loads from battery but it doesn't seem to make any difference. I suspect that maybe my meter is not installed correctly. I have mine measuring grid usage. Would I have to install a meter elsewhere? When I tested it a few minutes ago by turning on my water heater which is connected to AC out 2 it still used the battery. What are the prerequisites for this to work? I would think that the inverter would pull from the grid and supply AC out 2? Am I misunderstanding the workings of this setting?

Hi,

@mvader (Victron Energy) - in regards to Dynamic-ESS, is the ambition that it shall be integrated/included in the 3.10 release or is the native implementation of the Dynamic-ESS targeted for a a post 3.10 release of Venus OS?

I know I seen comments on menu alternatives visible in the later betas so I'm guessing its targeted for v3.10?

I'm asking since I'm eager to test it out, but are not running Venus OS large/Node Red, if the native implementation is targeted for 3.10 then I might as well install the v3.10 beta now, otherwise I'll wait until it starts to materialize a bit more.

My install is a 3P MP II with 20 Kwh Pylontech battery bank - I'm currently controlling the ESS system with Homey & the Victron integration in Homey (3rd party) to control self consumption/export to grid in the summer and price shaving in the winter- interested in seeing how much the upcoming native implementation will help me / simplify the control setup and perhaps permanently replace the Homey control loop.

I'm not sure if this is actually an issue but I've been looking at the prefer renewable energy mechanism. It appears that the automatic return to normal operator following a "charge battery to 100%" (from grid) is triggered when the Multi/Quattro internal state changes from Absorption to Float. The first issue is that the minimum absorption time is 1 hour and absorption may actually end sooner, at least with other charging sources

But with a managed battery that controls the charging, the absorption voltage set in the Multi/Quattro configuration might never be reached. This would cause the system to never return from "charge battery to 100%".

With non managed batteries, when the Multi controls the charging the Multi also returns to normal operation once the Absorption cycle is finished

The aux battery charging output does not have it's own algorithm, it will maintain a voltage slightly below that of the main battery bank, regardless of what state the charger is in. (Also stands true of when disconnected from incoming power) The aux battery output is not actually a "charger" perse, but the output is connected to the main battery bank via a diode which acts as a sort of one way check valve.

I Upgraded my Venus GX to v3.10-32 and it broke Generator auto on/off over Relay 1. No settings were changed after the firmware update - but Generator function will auto turn on (at set SOC) but will not auto turn off (at set SOC). VRM shows Generator graph going on and off correctly - but the Relay 1 graph shows it stays on even when Generator has "turned off". The result is the actual generator auto starts but will never turn off because Relay one is no longer switching it when it should. Obviously a bug in the new firmware. I downgraded back to v3.10-17 and it is working as normal again (correct auto on and auto off on Relay 1). Something to fix in the next firmware version please.
