Cerbo GX shuts down multiplus 12/1200/50

Cerbo GX shuts down multiplus 12/1200/50

Hi,

I installed a Cerbo GX initially everything worked apart from the A.C input, there is a lot of information why this might happen and I tried the recommended changes to the A.C inputs on the Cerbo GX touch screen, this did not work.

I then tried a software update using the touch screen after a couple of minutes my Multiplus 12/1200/50 had a low voltage alarm come on and the inverter turned off and now has a red light.

i still have communication to Multiplus and can switch the unit off and on through the Cerbo GX touch screen but still throws low voltage error and red light stays on.

I changed the software back to the old version on the Cerbo GX no change.

i disconnected the Multiplus and only connected the main positive and negative no change.

i think the inverter is still good i just cannot get rid of the low battery alarm, the D.C side is showing up perfectly on the Cerbo Gx and telling me that the batterys are full, I touched something on that cerbo touch screen i don't know what but it has stopped the Multiplus from working.

The software version in the Multiplus is 2662496

I have 3 active alarms on the Multiplus 291/288/276

Any assistant would be appreciated.

Regards

low battery warning

Did you update the multiplus firmware? If yes, then it might reset the settings to factory standard.

Was the multiplus working before you added the cerbo? Or did you install both devices at the same time.

What did you change on the ACin? That should not need configuration just to get it running, maybe some finetuning.

Whats the setting for low battery on the multiplus? Does it measure a DC voltage lower that that?

The inverter needs to be updated, there are some issues with 496.

You also then need to do the GX to 3.41 and make sure you update the mk3 bus, it will be in the inverter tab on the GX.

Configs have to be reapplied after inverter updates.

img-20240827-095832-hdr.jpgThankyou did the updates everything working except no data on the pages tab of Cerbo screen, but all the data I can see when i click on the inverter on the screen.

I am on a boat at anchor so I am super happy that the inverter is working again, I am not too fussed at the moment if I can not see data on the pages screen will fix it next time i am at port, but if you have any ideas would be appreciated.
