Cerbo GX Current Consumption

Hi, I am looking for current consumption of Cerbo GX @ 12VDC. For comparison, the Venus GX is listed at 210mA at 12VDC in the manual. Cerbo does not list any power consumption in the manual.

I would like to install on a boat mainly to link my MPPT via Wifi to the VRM website, but am concerned that the current consumption will drain batteries too much. I will be using 2x 50W panels, but would like them to primarily charge the batteries.

Hello. I would also like a know what the current consumption of Cerbo GX is. It's pretty basic info especially with this kind of gear. I'm trying to decide whether to go with Venus GX or Cerbo GX for my new installation.

I'm also interested (when powered by 24V).

Just a reminder, can you check current? Preferably with wifi on, wired ethernet off.

Sorry I doesn't had the time yesterday and today I'm also full of work.
I hope I have some time tomorrow.

Thank you! That's hugely appreciated. Is that with ethernet or wifi on, or both?

The range is typically between 2.5W and 5W - with a few more details in point 19 here - https://www.victronenergy.com/live/venus-os:start

It can be difficult to get a certain maximum - for example connecting additional USB accessories will draw more, as will more processing if there are many VE.direct devices, and if there is a GX touch screen connected how bright it is set.

But generally - Cerbo GX power draw without GX Touch mounted: around 2.8W. With GX Touch 50 connected, and backlight off: 3.8W. Backlight at max intensity: 4.8W

caf01399-b473-4501-ada7-6c372e3a5977.jpegIn line with the others above. Mine is drawing 0.4-0.5A (5-7W) with Cerbo GX, Touch 50 GX backlight off and a Glomex 4G/WIFI antenna.

cerbo-gx-160522.jpgHi everybody,

I have a Cerbo GX, together with a Quattro Multiplus 12V/5000, a BMV712 and a MPPT Solar from Victron.

I have been wondering about the power consumption of the Cerbo, which you can see on the picture is in the range of 70w to 130w. It is quite far away form the 20w mentioned here and I wondering what is going on.

I also noticed that the Ah deducted by the BMV 712 is higher that the real Ah consumed. for example, overnight the % of the batterie decrease from 100 to 90% and the following day, the battery charge to 95% reaching floating. The BMV noticed that the battery are full and reajust the SOC to 100%.

The problem is if I am not reaching the required voltage corresponding to 100%, the SOC reduce too much from about 5% everyday. for example 1 week ago, my battery voltage was 12,8V under 250w consumption but the SOC was 60%. This can not be right.

Can somebody help me? I hope it is quite understandable.

Thank you.


Best


Syl

one more precision: Cerbo is the only 12V device connected to the battery.
