Quattro firmware upgrade leave me with no ESS

A Split Phase system with two Quattros 48/10000/140-2x100 120v with Product ID 2754 was working with Venus v2.42 and we performed an upgrade of firmware on the Quattros to version 469.

After the upgrade of both Quattros we reconfigured via VE Config all the setting by uploading a saved version of the configuration. The setting where saved with no issues.

Once we brought the System online the Venus shows "No ESS Assistant found". We proceeded to go back and remove the assistant using VE config and adding it again, but the Venus still does not see the ESS Assistant.

Is Quattros firmware 469 for Product 2754 compatible with Venus OS 2.42? If not what would be the recommended software versions? If they are compatible what can I do to get the Venus to recognize the ESS Assistant from the Quattros?

How do I use the digital inputs in cerbo GX

Community, I’ve installed a Cerbo GX. I think I’m happy with the relay functionality. 3v3 octocouple relay to allow power to a 12v fan. The digital inputs are a whole other issue and are doing my head in.
I’ve read the manual and some background stuff but I think I’m not getting it.

1. Are the inputs powered at 3v3? Do I just need to complete a circuit to change the input state, I.e. short across the digital inputs (I don’t think this is the case but I need to check)?

2. So what I‘d like is a digital signal when the bilge pump goes on. Here’s what I think I need to do… Put a relay across the pump power. Have that provide a 3v3 signal to the cerbo digital input. I’m aware that I need a diode or octocouple to protect the cerbo from inductive current/voltage due to the relay coil. The problem is I can’t find such a circuit anywhere.

3. Because I can’t find anything it makes me think I’m way off with my plan. Can you guys suggest a better way of getting an on/off output from the bilge pump?

Thanks in advance,

Float/Absorption signal on Venus GX


I want to use the float/absorption signal to control an external device (geyser) Js this signal available on one of the Venus GX external terminals?

I am making useof the extra power after the batteries arefully charged, hence "float" despite some kWh would still be available.

Any other way to pick up that signal.

Thanks a lot

Add a second LiFePO4 battery bank - is my schematic ok?

Dear all,

For those interested: I'm going to add a second battery bank to my parents' installation.

This is the existing schematic:


I would modify the system using:

15 (not 16 as mentioned initially) times a 3.2V 200AH prismatic LiFePO4 cell, so 15s configuration. (click to open)

A would use a 16s 300A Daly BMS (because I hear nothing but good things about this BMS) (click to open)

Basically I would connect the now 15s (not 16s as mentioned initially) battery in parallel with the other 15s6p pylontech batteries.

Given that each battery in the future system will be connected in parallel, and each with it's own BMS, I don't see a problem;

The schematic would become (adding my homemade battery):



In practice I would simply add the homemade battery to the 2 copper bars, since there is room (free holes):


In theory I could add the system to VRM using CAN cable between Daly BMS & Victron Venus GX, but I don't think that's really needed. But it would be nice to see the battery in the system overview so that my dad can monitor it.

Please let me know if I'm being realistic or about to make a huge mistake.

Venus GX Remote Console White Screen

A strange thing has happened to my Venus GX Remote Console today. I connected using my laptop browser through VRM early in the day and all was fine, then later the screen just shows a white panel. Nothing I do seems to change the Remote Console display.


The Dashboard and other pages in VRM work fine and data is being measured by the Venus GX from my system, it is just the Remote Console that is blank. I have tried the following things:

1. Connect via VRM on my mobile phone: the screen is also white

2. Connect directly to the Venus GX using its WLAN connection from an iPad: also white screen

3. Power cycled the Venus GX: no change

4. Disconnected everything from Venus GX, power cycled then connected with WLAN on iPad: still no difference.

I am setup to receive beta Firmware drops automatically and the WLAN connection from VictronConnect shows Firmware: v2.60~21

Any ideas anyone? I love my Remote Console and really need it working again!

Multiplus-II with BlueNova BN52V-100-5.2k BP - What CAN Cable?


I am looking to install a Multiplus-II / Venux GX with a BlueNova BN52V-100-5.2k BP but am unsure what the the correct CAN cable/wiring/ is as the available Victron documentation is not conclusive for me and does not exactly match the BlueNova specification:

Can anyone provide a reference to the correct Victron CAN cable type to use or confirm if the BlueNova spec is correct?

In my testing I have been using the BlueNova recommended pin-out and I am seeing the battery appear as a connected device,


but the Details Page do not appear complete.


Can anyone confirm the correct CAN cable specification for this combination and any other relevant related configuration information?

The system has been set-up following this configuration as a Backup System.

Thanks in advance,

Venus GX - Two IP connections?

Today I noticed a new device in my (Unifi) network. The device was connected on the same switch port as the Venus GX and after connecting to the IP I did see the Remote Terminal Console interface of the Venus GX.

The device has it's own MAC address and is connected with an IP outside of my home network "IP range". I think this additional device is a result of the new firmware v2.30, but I'm not sure. I did btw disable the WIFI of the Venus GX.

The properties of the unknown/new device.


And the settings of the Victron Venus GX.


Anyone an idea why the Venus GX is connecting with a second IP connection?

Can the Venus GX control its relay based on battery SOC

When discharging the batteries to run a heat pump I want to switch off the heat pump if the batteries get to 10% SOC so that the pump doesn't start drawing from the grid. By switching off the HP it will automatically bring on the gas boiler which is more economical than the HP on grid lekki.

Time to go not changing

I just installed a BVM 712. I set the battery capacity and everything appears to be working but the time to go does not change. i ran every light and the fridge for over 12 hours last night and this morning the time to go is at 240 H which is the same as it was last night prior to running these things. The battery charge percentage came down from 100% to 93% so it seems to me that the time to go should have changed as well. What am I missing?

More than 2 MPPTs with Venus GX

Good day,

I currently have 2 * 150/60tr mppts on my solar system. They are connection via VE-direct ports (which the Venus GX only has 2 ports).

How can I go about adding another 1 or 2 150/60tr to the system?

is there no way to get them to sync using Bluetooth or something?

MPPT RS 450/100 connect via VE.can to Venus GX


i've 3 MPPT RS 450/100 connected via VE.Can to Venus GX.
At the end of the VE.Can bus are resistors connected.
I used normal UTP Network cabel cat.6. Max. Length of the cable is 3 meters.

Firmware MPPT 1.05
Venus 2.73

Remote Console
Settings/Services/VE.Can i cannot see any devices.

It seems the VE.Can is disabled ....

With the VictronConnect App connected via Bluetooth to the MPPTRS i found
no settings about VE.Can.

I hope everybody has an idea.

Thanks Thomas
