SBV restart?

Yesterday I updated the master, AC and DC firmware.

Today, after about 24 hours, there was a restart of the SBV. I know about this because my IT lab restarted completely and sent me emails. I use the SBV as UPS.

This is the first time of seeing this behavior. I use the SBV for about 3 months as UPS and there were no restarts - only after updating the firmware. It's only plugged to the AC input (230 V).

There are no error codes in the display.

AC firmware 2.2.2, DC firmware 1.1.6, master firmware 1.0.45. Between 08:00 and 19:00 I don't see any charging activity in the diagram. But it doesn't look like there was a long discharging of the battery because after 19:00 there were the normal short grid peaks when the SBV is charging the battery. And the battery ist charged to 89 %. I Set a charging limit to 90 %. If the battery would be discharged IT wouldn't be at 89 % now because I also limited the charging to 400 W.

I will see if this behavior will be repeated today and I will update this thread.

I forgot to say that the restart of the SBV or the AC output happened at about 22:40.

Yesterday there was no restart of the SBV or of the AC output. But I see error code 049 on the display and don't know what this means. Zendure still hasn't documented the meaning of this codes.

The Superbase V shut down and trips the circuit breaker when I turn on AC while charging from the grid. It doesn’t happen when using solar to charge.

There was no more reset of the AC output or restart of the SBV.

But I See now an error 049 in the display. What does this mean? It would be very helpful when the app can also display the error codes of the SBV - and ideally the meaning of these codes, too.
