The running dots showing current flows between the components shows current going to my Easysolar, even though it's switched off. (Switched off from VRM, physical switch on unit is on).

yesterday i created my account with victron professional and watched some training videos under training, after that i did the tests and passed them, unfortunately the next button is missing at the end. so i can download the certificate. it is also not displayed in my account, it says i haven't done any training yet.

Good morning,

I have just tried the MPPT calculator with a strange result.

I have 6 new Modules WINAICO WST-410MGX-P3 Gemini 410 W and hacked in all data and Victron recommended the SmartSolar MPPT 250/70 Tr VE.Can.

This is really strange, because my first Solarpanels set has 6 series panels with 310Wp and my SmartSolar MPPT 150/70 Tr VE.Can is at the limit.

How is it possible, that I get for 600Wp more power the same SmartSolar?

The 6 new 410Wp module have at 27,6V output already 89,13A.

Note: I have deactivated the 130% oversizing.

The primary VRM dashboard has been displaying old or erroneous temperatures intermittently for the past several days, for my Ruuvi Pro sensors. The advanced graphs show the correct readings, as do the sensors themself when you go into the device list on the Cerbo. The following screenshots were taken thirteen seconds apart, note the OUTSIDE reading. The other readings have small discrepancies as well, but not nearly as much.

What I have to report here obviously is not related to the devices I bought from different dealers but to the VictronConnect app which I bought (for 0 €) from the Google Play Store and the seller there is listed as Victron Energy BV. So the dealer to contact is Victron Energy. Yet on a similar occasion writing to the developer contact email address named in the app info in the Play Store I got a terse reply referring me to "the dealer". Thus, finding no more appropriate place I'm reporting the issue here.

When I opened the VictronConnect app this morning and headed to my BMV I got a warning message it could not load the settings file as it allegedly was created for a newer firmware but the Product Info page showed the device being on the latest firmware already. The same with my BlueSolar MPPT and it already happened once before.

I have a BVM712 Smart, that is transmitting Battery Voltage and Current sense. And I have a Smart Solar MPPT 150/85 that is receiving Battery Voltage and Current. The are in the same VE.Smart network. Firmware of the BVM is 4.12 and the firmware of the MPPT is 1.61

I have set the Max Charge Current in the MPPT (settings menu: Battery) to 26 A to make sure my battery is charged at 1C (my battery bank is 260 Ah).

When I look what happens now, is that when I have a load of 10A, the battery wont charge higher than 16A. With a load of 20A, only 6 A is charged into the battery.

This means that this setting is limiting the charger output instead of the battery input as provided by the BVM712.

I think this is a bug in the MPPT firmware.

As the setting clearly says "Max CHARGE current", and the charge current is provided by the BVM - the current measured by the MPPT itself is the charge current + load, so it should use the BVM value instead.

After adding a Victron EV-Charger to my system on inverter output, energy flow direction within VRM to and from Battery (here: Pylontech/BMS) works wrong (See also pivture). The flow sign shifts in both directions even it is actually in charged or idle mode. Before i upgraded the system with the EV Charger, energy flow was working fine and as expected.

Tried to post a question.

All fine until I tried to add a topic. No keyboard came up.

Phone was fixed in portrait orientation.

Removing the orientation lock and switching to landscape brought up the keyboard and I was able to post.

Hi Victron Energy,

if I initiate a CSV download in the advanced view of VRM portal with the range of a whole month, then sart and end timestamps in the CSV/XLSX export file do not match with "From" and "To" of custom range. The curious thing is that the data presented in the diagrams corresponds to the expected result, but the export contains a slightly different data slice. Even the generated file names contain different time specifications.

I would expect to have timestamps with values greater than or equal to "From" and less than "To", but the start and end timestamps in the resulting file will vary depending on the selected month.

Some examples:

Can this behavior be fixed?

Hello,

I have been using the Victron EV Charging station for two months now and it is installed close to an Wifi Access point. My problem is, that the unit becomes unresponsive over the network at times and the solution is to reboot it. Now for example, the dashboard looks like this in my browser. It never finishes loading the page. When the problem occurs it is sometimes possible to ping the unit.

Installed fw is 1.23.

On my Gx device screen the following is shown, where it says that the EV charger is not currently connected:

I hope that this is resolved in the coming firmware, something is making the unit really sluggish!

When selecting "this year" as the timespan for the system overview. I get different values for the consumption and production compared to hand selecting the time span 1.1.2023 0:00 until now.

The diagram shows that "this year" starts at monday 26.12.2022. I suspect it is a bug.

My Cerbo is running v2.92 and when creating a temperature alarm for my Ruuvi, the temperature is in celsius. Being from the US, my foundation is fahrenheit. Is there a way to change it for the alarm config? I changed my displays to F, it's just alarm creation that is still C.

Most LifePO batteries request absorption time To be set below 2 minutes. You guys need to fix this ASAP. This is a known issue with these Victron chargers.

I have Quattro-II 48/5000/70-2x50 + BMV-702 + SmarSolar MPPT 450/200 + LiFePO4 48V.

The 220V grid is connected to Quattro's AC In-1 and all load is connected to AC-Out-1 for now. There is no AC load bypassing the Quattro's AC Out.

I noticed that whenever I charge my battery from grid (both scheduled & unscheduled charge), I see that measured AC output power in VRM drops about 150w.

Which means that:

• If I have AC output power about 150w and start charging the battery from grid, the measured AC output current & power fluctuates below & above zero.
• If have output power about 1000w it will drop to about 850w. Which means that the inverter is capable of measuring output AC power while charging, but it is 150w off.

And the actual load does not change. This is measurement or calculation error.

Is this expected behavior? I can reproduce this consistently during day & night.

Also on the screenshot below you can see that input power is 3232w battery power measured by BMV-702 is 2781w. 3232-2781=451w. Output power is shown 14w but I know that it is fluctuates at about 150w.

If we do the math 2781/(3232-150)=0.90233614536 charger efficiency.

I have AC in limit set to 16A and grid charge power is about 3kW.

I did not limit inverter's output power via configuration. If I enable heavy load like 2kW and start charging, it charges at about 1kW not exceeding 16A which looks correct to me.
