It is not clear from your post what model chargers you are using.

@cagatay.sa hinoglu Communication via VE Can or VE Direct?

Seeing as it looses coms at night, is there battery voltage present at night on the mppt battery terminals?

We have 3 chargers. In the middle of the day we have same problem. Charger-1 via VE.direct, other chargers via ve.direct to usb.

In the same time battery voltage is good.

Communication comes back when I reboot the system anyway. It means there isn't any problem with voltage, is it? I think, It's a communication problem. But communication cables are good. Is there any possibility there is problem with venus?

It is looking like a comms problem with the 2 mppt's connected to the usb hub.

Is the BMV connected via VE Direct?

I would try another usb hub. Powered??

Venus GX, or CCGX?
