ESS System with some problems after power outages

Dear friends,

I have experienced a problem with a customer's ESS system. Multiplus and Fronius inverters are connected in parallel to the grid. There is a TOPzS batteries installed. ET112 meter and BMV700 is installed too.

My customer told me he noticed 2 power outages. I think the problem comes from the BMV monitor, but a problem from the grid meter has more sense as I have read in FAQ4 from ESS manual. I attached pictures from the VRM portal:





The previous night of a power outage, I found some error from the BMV monitor:




And this 25th april when I enter in the VRM portal, It showed an error message in a red window, it says something like "a device is trying to send data". I had to restore the token authorization in order to solve the problem But before restoring the token, I noticed this:



I called my Victron Seller in order to request them to write to level3support mail. But I have no news and no technical explanations.

Please, could you help me? If you need more information, please let me know.

Best regards,

Daniel.

Hi @Daniel Toribio

You asked 'How I have to check the grid meter?'

download the data on the timeframe where things go wrong and check in spreadsheet program.

And can you please resize the images? very difficult to read your posts.
