Cerbo GX Water Tank Level Sensor Recommendations Needed

Hi Folks,

I am excited about the tank monitoring capabilities of the Cerbo GX but I see so many different and highly technical posts. I really am hoping that by now there is a "plug and play" recommendation. I have three fresh water tanks and would prefer outside sensor install but whatever is proven and most accurate. I have access to all tanks from the top and sides. I also have the Cerbo connected to a BMV-712 and a Multi-plus inverter by the appropriate wire cables and then on to the Raymarine Axiom Pro(where I will hope to read the water levels in addition to the phone app or VRM).

Appreciate your recommendations.

Neil

Cerbo Reading Input Power different to Input Voltage and Current

In Advanced on VRM, I have put Input Power from the VE Bus System and Input Voltage/Current ontop of each other to check this over time. The Grid Setpoint is 0W and the input current is bouncing between -1.2 and +2.2 amps. The Input Power is however referencing a Power that is about 2kw lower than the AC Loads (Upto .

Site Info
The is no meter on site. The site is set up of 3 x Multiplus II inverters setup as a single phase. The GX is a Cerbo. All Firmware is latest firmware. The Cerbo Touch Display shows the Power reading. ESS is set to 40% without battery life.

Below are three different readings I have pulled from VRM.
Time/ Input Power/ Input Current/ Output Power
02:06/ 4248/ -1.5/ 7127
10:07/ 1827/ -1.4/ 2820
11:27/ 3023/ 1.8/ 4550

For all three of the above, the battery SOC was above the 40%.

The Current Values seem correct, and the input power values seem incorrect, however I will check the current values with a Clamp meter on site tomorrow.

Temperature Sensor with Cerbo GX and touch 50

Hi, I'm using a temperature sensor (ASS000001000) connected to the Victron Cerbo GX to measure the ambient temperature in one of the cargo bays in my vehicle. Two questions:

1) How do I configure the Victron Cerbo GX to show Fahrenheit instead of Celsius on the Touch 50?

2) The sensor is showing about 5 degrees higher than measured with other temperature devices. Probably because of its placement. Is there a way to adjust the display so it will display the actual ambient temperature? I would like to keep the sensor it its current place.

Thank you!

Cerbo losing connection to LTE modem

I've got a cerbo (with 2.60 f/w) and the newer LTE modem but the cerbo seems to lose the connectivity with the modem itself every day or so. When I look at the console, the message in the GSM page is "No GSM modem connected".

A reboot of the cerbo always restores the connection, so this isn't an electrical issue (USB plug being disconnected etc).

There doesn't appear to be any firmware update available/necessary for the modem.

Is it possible (I have root access enabled on the cerbo) to look at more detailed logs to help determine what the problem is?

Is this a known bug in 2.60?

Thanks for any advice.

How to display battery voltage from two BMV-700s on Raymarine Axiom 7?

I have two BMV-700s hooked up via VE.direct to a Cerbo GX. I have the Cerbo GX integrated with a Raymarine Axiom 7 via the network port AND VE.can. I can access both BMV-700s via the Victron App on the Axiom. I can get only one of the BMV-700s to populate the Battery 1 data box on the Axiom. I can't get either BMV-700 to populate the Battery 2 data box on the Axiom. I read the instructions and can change the data instance of each BMV-700, but I can't change the instance to 1. I can change the instance to 2,3,9, or 0, but I can't change it to 1. I used Actisence NMEA Reader and a NGT-1 to change data instances. All equipment and software has been updated to the latest rev.

12V Marine system help

Hi,

I will do my best to keep this short:

I have a 26ft. Sailboat on the Ossiachersee in Austria.

Because of weight, I want to switch from Lead Acid to Lithium. Because Lithium is so expensive, I want to switch from PWM to Victron MPPT for max battery protection (and max batt/solar efficiency.)

Unfortunately, due to different solar panel sizes, I can't have the PVs in series (see diagram).

Is my diagram here correct, or do I need less or more components?

Any info is greatly appreciated!

Cerbo GX Wifi access point connectivity issues

Hi all,

I installed an off grid system in my home last April which has been running fine with no issues.

Set-up: Cerbo GX (firmware 2.60 - no touch screen), Smartsolar MPPT150/60, MultiPlus 48/5000/70-100, 4x pylontech US2000

No AC input from grid or generator.

Mostly it is connected to the house wifi with no issues - in fact I didn't need to touch it until December.

During the middle part of December and up to the present I have been shutting down the Multiplus over night to conserve the batteries due to overcast days and/or thick frozen snow on the panels reducing production.

The problem: Connecting to the wifi access point after several hours. More precisely if I use the reset button on the Cerbo I can connect using an iphone or ipad, but after some time (variable between 2 and 12 hours) it seems impossible to reconnect without recourse to the reset button. I get a message that connection is impossible, or the password is incorrect etc.

I've tried using the "forget network" on the iphone and trying to reconnect, a la Blue tooth etc, but no joy. The only solution seems to be to physically reset on the Cerbo. This is somewhat inconvenient as access to the Cerbo is difficult.

I've also tried connecting with a Linux laptop with the same symptoms.

Question: Is there something I am missing in the network setups - I haven't changed any settings form the defaults. Networking is a bit of a dark art to me! Any ideas????

Thanks in advance

Cerbo GX Bluetooth connectivity limits

Hi I’m planning to get Cerbo GX and a GX Touch 50. Installation will be on a Sailing boat.

I already have an MPPT Snartsolar 100/20. I am planning to get also a smart shunt and use it to monitor two different battery packs.

First question: I want to connect the MPPT and the shunt using their Bluetooth capabilities. Is there some limitation in terms of functionalities compared to the cable option?

Se con question: I mentioned that the smart shunt should monitor two battery packs (two batteries for “house load”, one to start engine). I would like also to have a temperature sensors. Is there any Victron products that can use Bluetooth to share the data with the Cerbo GX? Or would be better to get two shunts and use the port for the temperature sensor? In this case I would have more questions to understand if temperature info is shared to the Cerbo and how the two shunts are displayed.


Thanks a lot!

Cerbo GX with 4 ve direct connections?

Hello,

I have a job existing with 3 MPPTs connected with a Cerbo GX and need to add in a shunt.

Reading the online manual for the Cerbo GX it only supports 3 ve.direct devices due to cpu power limitaions, but my supplier said a 4th one running off the usb to ve direct will work.

The lynx shunt is too exspensive and not practical here. Should I get the depricated vbc ve.net shunt or go for the 4th ve.direct to usb connection?


"The listed maximum on the `Performance` section in above table is the total connected VE.Direct devices such as MPPT Solar Charge controllers. Total means all directly connected devices plus the devices connected over USB. The limit is mostly bound by CPU processing power. Note that there is also a limit to the other type of devices of which often multiple are connected: PV Inverters. Up to three or four three phase inverters can typically be monitored on a CCGX. Higher power CPU devices can monitor more. "

Or am I interpreting this note incorrectly?

Should the system yield actually be the combination of the Total from each unit? How does one tell if they are working as a synchronised network pair. I have been unable to find any detail on the web or gain access to the Cerbo itself to look at the dBus data elements to see how they are interacting with the system.

Cerbo GX best connection to an old ESP DC link box shunt with Ve.net battery controller

On a motorhome I have an old ESP dc link box with ve.net shunt connected to a Ve.net battery controller to a Blu Power Panel, controlling a Multi 24/3000. Now I installed a Cerbo GX but I cannot view the Ve.net battery controller. I thought I could see it through the Ve.bus interface but I don’t.

As a solution I could install a smart shunt but I find it difficult to replace the ve.net shunt inside the ESP Dc box. Or I need to install a Bmv battery monitor and try to connect his shunt electronic to my old shunt on the ESP DC box? I do not like this solution as I have no panel space for the BMV display so I would prefer to have a smart shunt in the old ESP Dc link box to communicate via ve.direct with the Cerbo gx. Or a could replace my Blue power panel with a BPP2 that should have a ve.net to ve.bus converter so I should connect the Cerbo to the ve.net VBController ?

VRM monitoring site shows wrong data when bulk loading battery

All connected the way they should be, the smartshunt directly at the - of the battery, no mistake there.
When unloading, the vrm portal shows correct data.

However, when loading the batteries with the multiplus, I get the following data

This is not correct.
The only DC consumption I have is the shunt itself and the cerbo and that should be no more than 4W.
There is no AC consumption AT ALL, ie : nothing is connected on the AC-side of the inverter.

MultiPlusII Overreading Grid Power Value

I have a single phase 15kw system with three MultiPlusII inverters in parallel. There is no grid meter. The system is linked to four 150/100 MPPTS, with ESS set with battery life.

The Same is true for the output. What is causing this completely incorrect reading on the Power?
