Marine app issues:

I really like where this is going.

Tanks that should warn of low levels are showing high levels in red (see your screen shot above for e.g., oil. Also tanks that should warn of low levels are not showing levels in red e.g., water in your example above.

AC input is showing as unplugged but is obviously not since there is current flowing:

Energy Overview is mostly blank with large areas between the main number and the line below that shows other values. Seems like there is space for more info. Regardless, the summary line (e.g., voltage, current, power for AC output) should be brought closer to the top line in each section.

And in the example above, AC input current is shown as -- when the summary page shows current.

AC Load power and current are shown as negative values. In all other places in Victron GUIs these are shown as positive. This is also inconsistent with DC Loads which is shown as a positive number.

I can't find a way to select power as apposed to current. I realize that many want to see current but power is more constant across multiple subsystems (AC in/out and battery or PV charger.

Under Devices, not sure what the line "Bulk charging" is. If this is the Multi's charger output (to battery, it should be labeled as such. But this is not consistent with what's happening in my system at the time of the screen shot as the Multi is charging the battery at about 900 watts.

The Generator detail has a single button (Auto start/stop) which leads to a button set On/Off/Auto start/stop. Can't these be moved to the devices page? It's also not clear how to manually start the generator because of the button label.

For the non-technical people, I feel gauges are much more meaningful in that they show the value relative to its maximum. Gauges could in most cases be predominant over the numeric value.

Here is the main GUI screen shot of my system at the time the others were taken. Yes, I'm running GuiMods but have tested these issues without it.

Looking good, working well for me, however the generator input is signed as kw but the number is certainly Watts!

Note I am running GUI mods haven't had a chance to test without.

So a long time coming I have had some wema sensors for the tanks onboard, and I got around to installing them today.

Water tank went in perfectly, fluid was approx mid tank.

Black water tank no so much. Tank was empty and when I had connected everything it still said disconnected, checked my wiring which was fine then had a dive around the menu which said sensor 247.5 ohm. Ah! So I setup a custom range and away we go.

I thought though this probobly causes some confusion else where, so would a possible tweak in this scenario be rather than saying disconnected, instead out of range.

I really like the new GUI !

• The control page shows ESS control tile, even there is no ESS installed
• The control page does not show water pump control tile even a pump is configured.

Is there already or will there be a way to get the new GUI displayed on a touch 70?

Hi,

On updating to ~4 I had a lost BMS issue (lynx smart BMS) restarting didn't cure it.

Reverted to ~2 and that cured it.

Is there a possibility or can it be implemented in the software that the gui is cleaned up a bit, e.g. hide menu items that have no values in the bms view?

Not sure if this is the right spot to report this, vrm.victronenergy.com portal updated this morning, as was the Cerbo. Did that to check.

But I still cannot see the Serial Number of my replaced inverter on the portal under Firmware updates.

Just mentioning, in case that is an issue.

One issue I just noticed in the MFD app in both 3.2-7 and 3.1 (normal). My system as three Quattros plus lithium BMS. The battery BMS is configured to have battery status visible. Battery status for the three Quattros is hidden. In 3.2-7, none of the Quattros show up under Devices. I would like to see all three Quattros in Devices so I could turn them on and off. Thre is however a blank entry under Devices.

In 3.1, only one of the three Quattros shows up in the Inverter/Charger section

Hello! Please have in mind that all FRONIUS SYMO ADVANCED models are recognized by the GX devices as single phase pv inverters instead of multiphase. This makes all the readings to appear wrong. Fronius is already informed, but probably this is a Victron issue.

UPDATE:
I'm going to have to admit that I think this was my fault somehow.
After downgrading to 3.20~4 and step by step upgrading back to 3.20~7 so far I can NOT reproduce the problem.

ORIGINAL

I think there is an issue with graphed consumption on the "System Overview" graph on VRM with 3.20~7 that aren't in 3.20~4. I'm not 100% sure what it is but my graphs were way off.. reverted to 3.20~4 and it's normal.

I have ESS, with grid-tied solar on the input side.. Multiplus-II 3000/48 with PV via MPPT on the inside. At night we charge vehicles at 1am (about 20Kw)... and on average have 1KW on the inside of the Multiplus-ii as critical loads.

The graph before ~7 is correct... consumption at night, generation during the day while at work.
After ~7, the consumption at night is flat.. basically our constant 1KW of critical loads. And the consumption during the day is roughly the exact same as grid-tied solar generation minus critical loads (haven't done the math).... I have a Smappee monitor as well and it's accurate.

After downgrading to 3.20~4 VRM matches the Smappee output.

I think the grid meter output is being reversed with 3.20~7 such that consumption at night is treated as a negative number and during the day, production (negative) is treated as a positive number.

UPDATE:
Alright... I came back and looked at pictures and something is for sure up. I think it's with the VRM graph though. I exported the values from the "Advanced" view to excel and the output values for the cars charging at night show up, but not on the VRM graph.

I also went back to 9/27 (day ~7 came out)... Now I can't remember when I or it upgraded but 10/1 is when things started going sideways, middle of the day. Same with 10/2 middle of the day generation.

Here is today, solar graph.. everything from AC solar being consumed (we're not home...)... I remotely downgrade to ~4 around 11:30'ish..... and things change.


Here is Smappee output vs VRM today.. they start to align around noon.

Again.. the exported data from VRM advanced is correct but the graph is wrong (I think)

Hey,

i was updating from 3.11 to 3.20~9 and the presets of my Carlo Gavazzi counters were alll set to default "gridmeter".

and now i have the issue that i have a new device ID for my PV-meter

And as so often, once again the changelog before or shortly after the release (this time from 3.20~4 to 3.20~9) would be forgotten. Guys, this has to be better. It's not soooo hard, is it?

After updating to the 3.20~ 9 version, my ess system starts charging from the network even though the battery is sufficiently full.

Regarding this change: "Changes v3.20~5, 6 and 7"

• Dynamic ESS:
  • Fix problem with oscillation around the Dynamic ESS minsoc point. Once the system reached the minimum SOC, it would go back into normal ESS mode. This could cause the battery to start recharging, causing oscillation. Now we remain in DESS mode, but we go to idle, and set the ErrorCode accordingly (Low SOC).

Isn't this a bit simplistic workaround to the ESS bug described here:

https://community.victronenergy.com/questions/236751/ess-cycling-the-battery-10-of-minimum-soc-above-th.html?childToView=237032

that seems to originate from ... these lines at BatteryLife.py (also in "Optimized (without Battery Life)" ESS mode ?

It looks like oscillating between State SocGuardDefault and State SocGuardDischarged, with the small hysteresis from constant SocSwitchOffset.

A better fix to the Dynamic ESS oscillation around the dynamic MinimumSocLimit could possibly be to fix the non-dynamic ESS code when it cycles too around MinimumSocLimit , e.g. by adding one, possibly two States when self.soc is between MinimumSocLimit and MinimumSocLimit+SocSwitchOffset that is basically first stopping discharging the battery, then second state keeping the battery at least at that voltage/charge, and charging it with any solar in excess of loads?

I have a Cerbo GX with a GX touch 50 screen.

On updating to Venus OS V3.2 the screen stays on permanently, altering the time delay to shut off does not change anything.

Any ideas?

Thanks
