MPPT RS 450/100 off during sunny day, error code 27 during power up

I've 3 MPPT RS 450/100 which I installed 2 weeks ago. One of them had a problem during firmware update using Victron Connect and Bluetooth. Further updates in Victron Connect weren't possible because the device always reported firmware up2date (1.09).

But after startup of the Cerbo GX this device reported an error on the MPPT RS, error code 117, incompatible firmware error. Then I was able to update the firmware again and this time successfully, it seems.


And this device stopped working, produced no energy today. It was off most of the time.

In the evening I switched off the device. After powering it up again the Cerbo GX reported an error 27, Charger short circuit until I heared a clicking in the MPPT RS device.

Is the device faulty, or any suggestions what to do?

Thanks

Here is the same problem.
After the FW update to V1.09 the MPPT 450/100 the error 27 shows up.
This always happens during low load conditions in the morning or evening. (See time)

Victron please fix the firmware.
