Random shutdown Quattro without any alarm

Hello, we haven a 3-phase configuration with quattro 48/15000/200 converters.
Last week the quattro’s shutdown during bulk (soc 70%) without any reason, no alarms detected.
What I saw was that the characteristics looks frozen 10 minutes before shutdown. After general reboot problem was solved. Attached some examples of the characteristics.
SW Cerbo GX : V3.54
SW Quattro : V552
Anybody has simular problem.

Kind regards, Rudy.



Events like this can happen. If it becomes frequent enough to be annoying, then it will need to be looked into. Possible cause could be a loose connection either in a data cable or in a dc power cable.

Thanks for the answer Mike. Unfortunately it’s more then annoying for us when you deliver power for a international cycling race at the finish line ;-). I saw it already with the new cerbo SW on several machines that settings freeze and that have to perform a general reset.
Anayway,I will follow your advice and check the connections. Thanks.

Nothing goes over traditional technology, rent a diesel generator from Boels…

You get problems with diesel gens too, particularly noise…
Best to keep things as simple as possible.

Do you know something simpler then a diesel ?
