Cerbo GX can’t see Victron MPPT Charger

Hi, I bought a Cerbo GX few days ago, all is fine except that it doesn’t show MPPT charger (150/35). It sometimes shows it as a DC Power. I also have the BMV in this setup and I can see it on device list. Any ideas what could be wrong?

Try a different VE.direct port or try to use the cable from the BMV for the MPPT.
So you can figure out if the VE.direct port or the VE.direct cable are defective.

Can you see the MPPT via Bluetooth with the VictronConnect App?

You are spot on! I swapped the cables around and problem solved. Thank you so much!

I think this issue with the MPPT disappearing and appearing must be a bug. I don’t think it’s a cable issue. I get this a number of times per day.

A wrong contact between the connecter inserted into the mppt and itself. It happened to me.

Do you have an VE Direct cable hooked up between the mppt and your Cerbo?

Yes I do, sorry I forgot to mention that. I bought two cables. One for the BMV and the other for the mppt

My apology, I forgot to mention that I also have the direct cables for the BMV and MPPT hence I can see the BMV.

Check if one of the pins in the VE.Direct port in either the MPPT or the Cerbo is bended.

How long are the cables, and is there any inverter on the DC?

I have bad experience of cheap inverter killing all communication on CCGX when turned ON.

I have 2 x 1,8m cables. One is for BMV and the other for MPPT. My installation is made up of Victron products namely:

Multiplus 48/3000 50amp

1x Victron 150/35

1 x BMV

Cerbo GX

I have been monitoring my MPPT 150/35 charger for over six months now, the issue of the mppt disappearing and re appearing has nothing to do with lose cable. This is the sequence of events:

1. Once it disappears, I go to setting of the Cerbo GX and refresh the device list and delete the the MPPT

2. Refresh the page and exit from there onwards the MPPT reappears again.

My setup is as folllows:

Victron Multiplus 48/3000-35/50, Cerbo GX, 4x Shoto 200AH batteries in series, 3 x Victron battery balancers, Victron MPPT 150/35 rev 2 and they are all on latest firmware.

Surely this has to do with the software, I look forward to hear from other forum users.
